1.0 2012-03-22 Gregory Nutt * The initial release of the NxWidgets package 1.1 2012-05-19 Gregory Nutt * Updated and verified the NxWidgets DOxygen documentation. Contributed by Jose Pablo Carballo. * IBitmap, CRlePalettBitmap: Extended class to support differnt LUTs for selected and non-selected images. * CImage: If selected, uses different LUTs based, different borders. CImage is now basically a button type. * CImage: Add logic to hightlight an CImage (using the selected LUT). * nxwm: The tiny NX window manager (NxWM) is being developed in this directory. * UnitTests/nxwm: A unit test for the NX window manager. * CWidgetControl: Add a semaphore to force clients to wait if the size or position of the window is not yet known (multi-user mode only). * During integration of NxWM, corrected numerous problems with NxWidgets running on toolbars and framed windows. That capability was commented out in the 1.0 release but is verfied functional in 1.1. * CRlePalettBitmap: Fix an error in the text that determines if we need to "rewind" to the beginning of the image. * CRlePalettBitmap: Fixe a positioning problem. It was actually losing the last row of every image! * CNxWidget: Removed support for "shelving" widgets. I will be removing some lesser used feature over time in order to reduce the NxWidgets footprint. * CNxWidget: Removed support for reference constants and close types. The goal is to ge the base widget class as small as possible. * CNxTkWindow: Fix uninitialized pointer value. * CNxToolbar: Need to "fake" the fix position callback to avoid deadlock waits for the callback that won't happen. * CNxTkWindow: Fix toolbar background color * CWidgetControl: Don't declare the the geometry is good until a non-NULL window size is received. * CGraphicsPort and CWidgetControl: If the underlying graphics device is write-only, then we have to render fonts a little differently. * CNxWidgets, CWidgetControl, and CRectCache: Big change! Remove all support for widgets in a "vertical" hierarchy. Now widgets exist in a flat, two-dimensional space and should not overlap. This should greatly reduce the memory requirements and, since, NuttX already supports a hierarchical windowing system, does not result in loss of functionality. * CNxWidgets and CWidgetControl. Remove specific built-in support for modal loops. There are too many different control mechanisms that might be needed. Replace with hooks to control widget events from totally external logic. * CWindowEventHandler, CWindowEventHandlerList, CWidgetControl: New callback classes to receive notifications about window events. * NxWM::CFullScreenWindow and NxWM::CTaskbar: Add support in NxWM for full screen window applications. * All application windows now use CWindowEventHandler and CWindowEventHandlerList to get notifications about mouse and keyboard events. These class will then automatically handle polling (with no need for a modal loop). * NxWM::CTouchscreen and NxWM::CCalibration: Add touchscreen support (still a long way to go). * NxWM::g_playBitmp: Change the play icon again. These tiny touch icons must be very simple. * NxWM::CCalibration: Beef up touch input handling logic. Now changes the color of the touch circle to yellow when it is touched. * NxWM::CTouchscreen: Do not read touchscreen data when there is no consumer. * NxWM::CWindowControl: Add new class to wrap CWidgetControl and provide some special mouse and keyboard input event handling. * NxWM::CTaskbar: Correct the calculation of the physical size of the display. * NxWM::CCalibration: run method must clear m_stop when returning, or you can never restart the Calibration window. * NxWM::CTaskbar: On a failure to start an application, the application icon CImage was being deleted twice. * NXWidgets::CImage: Now handles mouse click callbacks. CImage is now really a button. Probably should separate basic imaging functionality as CImage and create a new CImageButton. * NxWM::CStartWindow: Now ignores any close application button presses (You can't close the start window). * NxWM::CCalibration: The calibration application now has its own thread. This was necessary for a proper integration with the taskbar. * NxWM::CCalibration and NxWM:CTouchscreen: Changed the mechanism use to report calbration data. It is now reported directly from CCalibration to CTouchscreen. If external logic needs calibration, it can now get it from CTouchscreen instead of CCalibration. This change was necessary to make the termination conditions of CCalibration clean (it used to have to persist until some external logic got the Calibration data). * IApplication, IApplicationWindow, and all classes that inherit from these: Now support method to report if the application is a full-screen or a normal application. This is necessary to prevent CTaskbar from displaying a task bar on top of a full-screen window. * NxWM::CTaskbar: Ooops... minimizing the wrong application! * NxWM::CNxConsole: Add a on_exit() exit handler that will close the NxConsole window when the NSH thread exits. A correct build now depends on having CONFIG_SCHED_ONEXIT defined. * NXWidgets::CNxWidget: Add a new onPreRelease() method. * NXWidgets::CButton, CButtonArry, CImage now post action event at pre-release time. * NxWM: ICON touches are now drive by action events instead of click events. * NXWidgets::CNxTkWindow: Reported size of a framed window must exclude the height of the tool bar (if present) * TODO.txt: Add a file to keep track of issues. * NxWM::CStartWindow and IApplicationFactory: This is a substantial redesign. IApplication wraps an application. However, if we want to be able to start multiple copies of an application, then we need to be able to create multiple IApplication instances from the start window. Enter IApplicationFactory. Icons in the start window now correspond to application factories; icons in the task bar no correspond to application instances. * NxWM::CStartWindow and CWindowControl: The above change necessitated another architectural change: When create applications, it is sometimes necessary to wait for windows events. The above change moved the application creation to the window event thread, hence, causing deadlocks wheneven the logic tried to wait for a window event. The solution was to create a new thread, called the start window thread, that runs asynchronously and can wait for windoew events. * doc/NxWM-ThreadingModel.ppt: Documented the now rather complex NxWM threading model. 1.2 2012-06-15 Gregory Nutt * NXWidgets::CCallback: callback arguement is now type CCallback and not CWidgetControl; Added a method to redirect keyboard contacts to either the widgets in the window (via CWidgetControl) or to an NxConsole (via nxcon_kbdin()). * NXWidgets::INxWindow, CBgWindow, CNxTkWindow, CNxToolbar, CNxWindow: Now pass the CCallback intances as the callback argument instead of the CWidgetControl instance. New method redirectNxConsole() will support redirection of any window keyboard input to the NxConsole (via CCallback). * NxWM:CNxConsole: Configures the NxConsole window to redirection keyboard input to the NxConsole; redirects standard input to the NxConsole device driver. * NxWM:CKeyboard: Add a new class that implements a keyboard listener thread. This thread reads from /dev/console and injects the keyboard input into NX. NX will determine which window is at the top of the heirarchy and re-direct the keyboard input to only that top window. This solves an important problem with, for example, running multiple copies of the NxConsole: On the copy of the NxConsole at the top of the heirarchy should get the keyboard input. * UnitTests/nxwm/main.cxx: Now starts the keyboard thread if CONFIG_NXWM_KEYBOARD is defined. * NxWM::CTaskbar: After drawing the task bar, need to raise the application window otherwise the taskbar will be on the top and keyboard input will not be received by the top application. * NxWM::CTaskbar: Bugfix... previous window should not be minimized when a new window is started. It should stay in a maximized state so that it will re-appear with the window above it is closed or minimized. * NxWM::CHexCalculator: Add a hexadecimal/decimal calculator example. * NXWidgets::CNxTkWindow: Back out height adjustment in the getSize() method. The code was correct as it was before. * NXWidgets::CButtonArray and NXWidgets::CGraphicsPort: There is a kludge in there to handle the case where we cannot read the background data because the LCD does not support read operations. In that case, we just use the default background color. However, that doesn't work either for the case where the background color changes when the widget is selected. Then the background color in the font is wrong. Fixed in CButtonArrary, but the problem probably exists in other places as well. * NxWM: Increase default spacing of icons on the Start Window. * NxWM::CHexCalculator: Fix some non-standard calculator behavior after = is pressed. Use upper case hex. Increase font size. * nxwm/Makefile: Fix error that creapt in during some other recent check-ins. 1.3 2012-09-29 Gregory Nutt * UnitTests/*/main.cxx: Change entry point name to be consistent with with entry point naming conventions introduced in NuttX 6.22. * Kconfig: Added a mconfig configuration file. Eventually, NxWidgets needs to get hooked into the NuttX mconf configuration. Still not exactly sure how to do that. * libnxwidgets/Makefile and NxWidgets/nxwm/Makefile: Need updates for consistency with recent changes to NuttX build system (>= 6.22) * Kconfig: Add option to turn on the memory monitor feature of the NxWidgets/NxWM unit tests. 1.4 2012-12-20 Gregory Nutt * libnxwidgets/Makefile, NxWidgets/nxwm/Makefile, and NxWidgets/UnitTests/nxwm/Makefile: Makefile improvements from submitted by Petteri Aimonen. Other Makefiles in the UnitTests directory probably also need these changes. * libnxwidgets/src/ccallback.cxx: Fix misplaced #endif. Provided by Petteri Aimonen. * libnxwidgets/src/cnxserver.cxx: Reduce delay to allow NX server to start. One second was un-necessarily long. Reduced to 50 MS. Reduction suggested by Petteri Aimonen. * tools/bitmap_converter.py: This script converts from any image type supported by Python imaging library to the RLE-encoded format used by NxWidgets. * NxWidgets/nxwm/src/capplicationwindow.cxx: If the "desktop" is empty, users have no need to minimize any windows. If the buttons are small, it's easy to hit minimize button accidentally when trying to close an application. Contributed by Petteri Aimonen. * NxWidgets/nxwm/src/ctaskbar.cxx: Add an option to eliminate the background image. Contributed by Petteri Aimonen. * NxWidgets/nxwm/src/chexcalculator.cxx and NxWidgets/nxwm/src/cstartwindow.cxx: The config settings CONFIG_NXWM_STARTWINDOW_ICON and CONFIG_NXWM_HEXCALCULATOR_ICON allow changing the icons used for these applications. However, to declare symbols for these icons user would need to modify NxWidgets header files. This commit adds a simple forward declaration to the relevant files, based on the configured icon. If the icon does not exist, linker will give an error about it. Contributed by Petteri Aimonen. * NxWidgets::CTaskBar: Highlight the current window in the task bar. Contributed by Petteri Aimonen. * NxWidgets/libnxwidgets/src/glyph_cycle.cxx: Width of glyph_cycle was wrong; Destructor needs to by public. From Petteri Aimonen. * NxWidgets::CNumericEdit. This is basically a label with plus and minus buttons. Contributed by Petteri, Aimonen. * NxWM::CStartWindow: Fix mq_receive error handling with signal is recieved. From Petteri Aimonen. * NxWidgets::CNxTimer: Replace the original (apparently non-functional) signal- based solution with a work queue-based solution. This raises some isses about using the internal work queues from user space. I have decided to implemented user-space work queues (someday) in order to accomplish that functionaliy. Submitted by Petteri Aimonen. * NxWidgets:CText and NxWidgets:CNumericEdite: Fix some memory freeing bugs (from Petteri Aimonen). * NxWidgets::CScrollingPanel: Usability improvements. It is borderless for now, because there was no easy way to redraw only the required part of the border. Contributed by Petteri Aimonen. * NxWidgets::CNxWidgets and NxWM::CStartWindow: Small changes to make sub- classing easier (from Petteri Aimonen). 1.5 2013-02-01 Gregory Nutt * NxWidgets::CGraphicsPort::move(): Fix typo bug in bounding rectangle calculation (from Petteri Aimonen). * NxWM::CScrollingPanel::scrollChildren(): Avoid unnecessary redraws in CScrollingPanel (contributed by Petteri Aimonen). * NxWM::CCycleButton: Remove the separator from CCycleButton. It draws in wrong place, and doesnt look very good in the correct place either. (from Petteri Aimonen). * NxWidgets::CGraphicsPort: Many times we only want a constant background. In that case the old code fills the background, reads it back, renders the text and then writes it back. When used with LCD's (instead of framebuffers) this causes unnecessary delay and screen flicker. This commit adds a variant of drawText that takes background color, so that the background and text can both be rendered at one go. The old functions still function as before (Petteri Aimonen). * NxWidgets::CLabel: The label was drawn as a single rectangular region, then a text was added to the on top of this. The result is that the text would flicker when the CLabel was updated. With this change, the two step update is replaced with a five step update: The background is updated as four rectangulear regions (leaving the previous text in place), then the new text is updated. This eliminates the flicker (Petteri Aimonen). * Kconfig: Many NxWidgets/NxWM settings do not have meaningful, generic default values. Colors, for example, depend on pixel depth. Some geometry settings depending on other geometry settings. Font IDs are not know-able by the configuration system. etc. In these cases, it is best if the settings are just not undefined so that the system can calculate a reasonable default. however, if no default is provided in the .config file, mconf will complain and generate errors. So work around this, I added several "enabling" settings to override the default setting. This is awkward and I preferred the configuration as it was before, but this avoids the mconf errors and warnings. * UnitTests: Changed occurrences of lib_rawprintf() and lib_lowprintf() to match recent changes to NuttX (will be in NuttX-6.25) * CGraphicsPort::_drawText: Renamed from CGraphicsPort::drawText in order to eliminate some naming collisions when overloaded in some configurations (i.e., when both bool and nx_pixel_t are uint8_t). From Petteri Aimonen. * CNxWidgets::drawContents: Change base drawContents from a do-nothing function to a function that fills the widget with the background color. This is useful when using CNxWidgets as a "panel" , i.e. a container for other widgets. Subclasses will override drawContents and decide themselves how to draw the background. * CNxWidgets::CTabPanel: A new widget contributed by Petteri Aimonen. This widget provides a tab panel, which has a button bar at the top and panels below it. Pressing a button will select the corresponding panel. 1.6 2013-03-15 Gregory Nutt * Type of argv[] has changed from const char ** to char * const * * NXWidgets::CNxWidget: Add an inline function to get the current style. * NxWM::CTaskBar: Make a some methods of CTaskbar virtual to allow customizations. From Petteri Aimonen. * NXWidgets::CCycleButton: Make CCycleButton change state in onPreRelease(). This way the new value is already available when a listener gets the action event. From Petteri Aimonen. * NxWidgets/tools/bitmap_converter.py: Fix bitmap_converter.py so that it works with indexed input images. * NxWidgets::CLabel: Fix backward conditional compilation in the "flicker free" logic. * NxWidgets::CNxTimer: Previously repeated timers were re-enabled after the timer action event. Consequently, if the action event handler tried to stop the timer, the request would be ignored. Changes the order so that the timer is re-enabled before the callback. There is still no risk of re-entrancy, because everything executes on the USRWORK work queue. From Petteri Aimonen. * NxWidgets::CMultiLineTestBox: Fix text placement error. From Petteri Aimonen. * NxWidgets::CWidgetControl: Added another semaphore, boundssem, which is set as soon as the screen bounds are known. This corrects two problems: 1) Due to the way nxgl_rectsize computes the size, it will never be 0,0 like CWidgetControl expects. Therefore the size is considered valid even though it has not been set yet. 2) After the check is fixed to test for > 1, NxWM window creation will hang. This is due to the fact that it uses the screen bounds for determining window size. This was being blocked on geosem, which is only posted after the size has been set. From Petteri Aimonen. * NxWidgets::CImage: Two enhancements: 1) Allow changing the bitmap even after the control has been created. 2) Allow giving 'null' to have the control draw no image at all. From Petteri Aimonen. * NxWM::CTaskBar: Allow windows with null icon. This makes sense for e.g. full screen windows. From Petteri Aimonen. * NxWM::CApplicationWindow: Add config options to override NxWM stop/minimize icons. From Petteri Aimonen. * NwWM::CStartWindow, NxWM::CWindowMessenger: Get rid of the start window thread. Instead, handle all events through the USRWORK work queue. For me, this was necessary because I would open some files in button handlers and close them in NxTimer handlers. If these belonged to different tasks, the close operation would fail. Further benefits: + Gets rid of one task and message queue. + Reduces the amount of code required + Decouples CStartWindow from everything else - now it is just a window with application icons, not an integral part of the event logic. + All events come from the same thread, which reduces the possibility of multithreading errors in user code. + The user code can also send events to USRWORK, so that everything gets serialized nicely without having to use so many mutexes. Drawbacks: - Currently the work state structure is malloc()ed, causing one allocation and free per each input event. Could add a memory pool for these later, but the speed difference doesn't seem noticeable. - The work queue will add ~50 ms latency to input events. This is however configurable, and the delay is anyway short enough that it is unnoticeable. From Petteri Aimonen. 1.7 2013-04-28 Gregory Nutt * NxWidgets bitmap_converter.py: Fix bug when image width > 255. From Petteri Aimonen (2013-4-22). * NxWM::CScrollbarPanel: Fix spelling error in class name: CScollbarPanel should be CScrollbarPanel. From Petteri Aimonen (2013-4-22). * NxWidgets:: CGlyphButton: Generate action event, like CButton does. From Petteri Aimonen (2013-4-22). * NxWidgets:: CGlyphButton: Prevent drawing outside of the bitmap size. From Petteri Aimonen (2013-4-22). * NxWM::CTaskBar: Add option CONFIG_NXWM_TASKBAR_NO_BORDER to suppress drawing of the border on the taskbar. From Petteri Aimonen (2013-4-22). * NxWidgets::CNxTimer: Add function to check if CNxTimer is running. From Petteri Aimonen (2013-4-22). * NxWidgets::CNxWidgets: Allow overriding of the checkCollision() method. From Petteri Aimonen (2013-4-22). 1.8 2013-06-14 Gregory Nutt * NxWM::CMediaPlayer: shell application for an MP3 Media Player with Kconfig settings to enable it. I plan to write this app to help develop and test the MP3 codec chip driver. It really doesn't do anything yet except display a text box saying "Coming soon", and I need to minimize the icon size a bit. From Ken Pettit (2013-5-11). * NxWidgets/nxwm/src/glyph_mediaplayer.cxx: Smaller version of the media player glyph. From Ken Pettit (2013-5-12). * NxWidgets/nxwm/include/ccalibration.hxx and src/ccalibration.cxx: Fix a race condition that would cause the calibration screen to fail to come up when its icon was touched (From Ken Pettit, 2013-5-12). * Kconfig: Default priorities for NxWidget and NxWM threads should be 100, not 50, to be consistent with other default priorities. * NxWidgets::CGlyphSliderHorizontal and NxWidgets::CGlyphSliderHorizontalGrip: New widgets added by Ken Pettit (2013-5-15). * NxWidgets/UnitTests/CGlyphSliderHorizontal: Adds a unit test for the NxWidgets::CGlyphSliderHorizontal class. From Ken Pettit (2013-5-17) . * NxWidgets::CGlyphSliderHorizontal: Fix a drawing error. From Ken Pettit (2013-5-17). * UnitTests/*/Makefile and .gitignore: Update the way that NSH the Unit Tests are registered as built-in NSH applications (2013-5-30). * NxWidgets::CImage: Allow a NULL pointer for a bitmap. Add protection to prevent dereferencing the NULL pointer. From Petteri Aimonen (2013-6-4). * NxWidgets::CNumericEdit: Delay before auto-incrementing now varies: A longer delay is required to start auto-incrementing and speed increases while pressed. From Petteri Aimonen (2013-6-4). * NxWM::CTaskbar: Add a method to redraw the taskbar and the current application. This should only be necessary if the display loses state due to e.g. powerdown or other manual intervention. From Petteri Aimonen (2013-6-4). 1.9 2013-10-28 Gregory Nutt * NxWM::CCalibration.cxx/hxx: If CONFIG_NXWM_CALIBRATION_MESSAGES is defined then CCalibration will provide some instructions in the center of the display (2013-10-14). * NxWM::CCalibration.cxx/hxx: Add options to collect and average multiple samples at each location. Also logic to discard the most extreme samples before averaging (2013-10-14). * NxWidgets::CScaledImage: This new class is a wrapper for an class the exports IBitMap. It will perform scaling via bi-linear interpolation so that images can be scaled to any size desired (2013-10-15). * NxWM::CTaskbar:: Can now be configured to scale taskbar icons using NxWidgets::CScaledImage (2013-10-15) * NxWidgets/libnxwidgets/src/glyph_nxlogo320x320.cxx: Add a big, 320x320 NuttX logo image. The older, smaller NuttX logo was renamed from nxlogo to nxlogo160x160 in all places (2015-10-15). * NxWM::CCalibration and NxWM::CTouchscreen: Add a complex touchscreen scaling algorithm to handling the case where the measured X values also vary with y position (and vice versa) (2013-10-17). 1.10 2013-12-07 Gregory Nutt * Kconfig and UnitTests/nxwm: Add logic to enable saving and recovering touchscreen calibration data. This depends upon having platform-dependent support for storage of configuration data. Portions suggested by Ken Pettit (2013-10-30). * NxWM:Calibration: Saving of calibration data must be performed in CCalibration, not in UnitTests/nxwm. Why? Because the touchscreen calibration could also be initiated from other ways other than through the one-time, start-up initialization logic (2013-10-30). 1.11 2014-01-30 Gregory Nutt * NxWidgets/Kconfig and NxWidgets::CNxServer: Server initialization can now be disabled in the configuration (in fact, it is disabled by default). This is because in the kernel build mode, the NX server must be initialized in kernel mode by the RTOS before applications using the server run in user mode. * NxWm: Added CONFIG_NXWM_NXCONSOLE that can be used to disable the NxConsole window (2013-12-30). * NxWm::CTouchscreen: Added CONFIG_NXWM_TOUCHSCREEN_DEVINIT that can be used to suppress calls to initialize the touchscreen device from the listener thread. This is necessary if the kernel mode build is used: In that case, the touchscreen must be initialized in kernel space before NxWM is started (2013-12-30). 1.12 2014-xx-xx Gregory Nutt * libnxwidgets/include/nxconfig.hxx and libnxwidgets/src/cscaledbitmap.cxx: Fix typo RBG -> RGB. This makes NxWidgets incompatible with versions of NuttX 7.2 and below. * nxwm/src/glyph_*.cxx: Rename all ICON glyph files to include the size of the ICON as part of the file name. This is in preparation for supporting a set of larger ICONs (2014-7-12). * nxwm/src/glyph_play48x48.cxx: Add a larger NxWM play icon (2014-7-12). * nxwm/src/glyph_caclulator47x49.cxx: Add a larger NxWM calculator icon (2014-7-13). * nxwm/src/glyph_cmd49x43.cxx: Add a larger NxWM NxConsole icon (2014-7-13). * nxwm/src/glyph_calibration48x42.cxx: Add a larger NxWM Calibration icon (2014-7-13). * nxwm/src/glyph_minimize42x42.cxx: Add a larger NxWM minimize icon (2014-7-13). * nxwm/src/glyph_stop42x42.cxx: Add a larger NxWM close icon (2014-8-13). * nxwm/src/glyph_mediaplayer44x50.cxx: Add a larger NxWM media player icon (2014-7-14). * Kconfig, nxwm/include/nxwmconfig.hxx, nxwm/src/capplicationwindow.cxx: Toolbar font ID can now be separately configured (2014-7-14). * nxwm/src/cmediaplayer.cxx: Will not dynamically position player controls based on the display and image sizes (2014-7-14). * nxwm/src/glyph_mediagrip30x30.cxx and glyph_mplayer_controls43x41.cxx: Add larger images for the media player (2014-7-14). * Kconfig, nxwm/src/cmediaplayer.cxx: Add options to manage spacing of media player buttons and borders vs. borderless buttons (2014-7-14). * NxWidgets::CImage: Fix setImageLeft and setImageTop methods (2014-7-14). * NxWidget::CImage: Now supports helper methods to align images in the widget region (2014-7-14). * NxWM::CMediaPlayer now uses the new CImage methods to align media controls in buttons (2014-7-14). * NxWidgets::CStickyImage: A version of CImage that sticks in the selected state when clicked (2014-7-15). * NxMW::CMediaPlayer: Now supports a pause button (2014-7-15). * NxMW::CMediaPlayer: Fix some memory leaks (2014-7-16). * NxMW::CMediaPlayer: Change spacing, make text region big enough to support a multi-line, scrollable region (2014-7-16). * NxMW::CMediaPlayer: Correctly catch the volume level change event (2014-7-16). * NxMW::CMediaPlayer: Concert CLabel to a CListBox to support selection of one of many media files to play. This should be a CScrollingTextBox to support an indefinitely large number of media files (2014-7-16). * NxWidgets::CGraphicsPort: Fix drawBitmapGreyScale method. Actually drew nothing because of several errors in positioning and buffer usage (2014-7-17) * NxWidgets::CImage: Should not attempt to draw the "empty" regions at the top and the bottom of the image box in greyscale (2014-7-17). * NxWM::CMediaPlayer: Fix some state-related bugs introduced yesterday. Improved state-related button displayes. Now correctly catches and handles file selection events (2014-7-17). * NxWidgets::CImage: Cannot use NxWidgets::CGraphicsPort:drawBitmapGreyScale() because it does not respect transparent or background colors in its current form. The end result is that makes the image background grey as well as the image (2014-7-17). * NxWM::CMediaPlayer: State variable was left in a bad state and caused some problems down the road (2014-7-17). * NxWidgets::CGlyphSliderHorizontal: No longer uses a hard-coded slider height; the slider height is now provided as a parameter, replacing the widget height which is now calculated from the glip image height (2014-7-17). * NxWM::CMediaPlayer: Now calculates the volume slider height from the grip image height (2014-7-17). * NxWM::CApplicationWindow: Created the custom font for the toolbar title, but never used it! (2014-7-17). * NxWidgets::CNxString: Make destructor virtual. From Petteri Aimonen (2014-7-22). * NxWidgets::CTaskbar: Fix type of return value fromopenRawWindow() method. From Petteri Aimonen (2014-7-22). * NxWidgets::CTabPanel: Modify behavior in showPage() method. Eliminate a duplicate redraw that caused flickering; re-order some logic so that widgets are hidden before operated on. From Petteri Aimonen (2014-7-22). * NxWidgets:CTabPanel: Make CTabPanel raise action event when tab is changed. Also add a function for getting the currently selected tab index. From Petteri Aimonen (2014-7-22). * NxWidgets::CNxTimer: Make CNxTimer stop itself before destruction. Otherwise a call to an invalid work queue entry may occur. From Petteri Aimonen (2014-7-22). * NxWidgets/Kconfig: Add configuration options to filter CMediaPlayer files based on extension (2014-7-23) * NxWM::CMediaPlayer: Add logic to read files from the media mountpoint, filter them by extension, and display the file names in the listbox (2014-7-23). * NxWM::CMediaPlayer: Beginning integration of NxPlayer into Nxwm::MediaPlayer. Gets handle, sets device, and releases handle. Lots more to be done (2014-7-23). * NxWidgets::CNxString: Add a getAllocSize() method to make it easier to convert CNxStrings to NUL-terminated C strings (2014-7-24). * NxWM::IApplicationFactory: dd a do-nothing, virtual destructor to eliminate a warning (2014-7-24). * NxWM::CMediaPlayer: Lots of changes to integrate with Ken's NxPlayer (2014-7-24). * NxWM::CMediaPlayer: Revise state logic. We need an additional state for the case where a file is selected, but playing has not yet start. Several other state-related fixes (2014-7-25). * NxWM::CMediaPlayer: Need to remember last text box selection or else each new Value Change event from the volume slider is confused with a new file selection (2014-7-27). * NxWM::CMediaPlayer: Correct handling of increments to sub-sampling rate (2014-7-27).
