apps/graphics/nxwidgets/src/cbuttonarray.cxx: Correct an error CButtonArray. Was not correctly resizing the widget when the dimensions of the button array changed.
apps/graphics/twm4nx: Trival correcion of some typos in comments.
apps/graphics/twm4nx: Rename IDragEvent interface to IEventTap. I intend to reuse this interface for window resizing as well as dragging.
apps/graphics/twm4nx: Some trivial elimination of some unused logic in CResize.
apps/graphics/twm4nx: In the Icon Manager, do not use the window name to identify which button press corresponds to which Window. Window names are not unique. Instead, it now keeps track of thich row x column was assigned to the window name. That row x column uniquely associates a window with a button and does not depend on the window name in any way.
apps/graphics/twm4nx: Fix an error in event notification sent by the Icon Manager when a window is selected.
apps/graphics/twm4nx: Correct logic in Icon Manager for the case where the number of windows causes the Icon Manager to increase in size by one row.
apps/graphics/twm4nx: Add logic to detect collisions with reserved regions in the backgroud or with other icons when moving an icon on the desktop.
apps/graphics/twm4nx: When moving icons, erase the old icon image before drawing the new one.
apps/graphics/twm4nx: Fix several errors associated with the NxTerm buttons. Most changes involved fixing crashes with the exit button is pressed. Now the NxTerm windows behave well. However, they are not receiving console input so there is still more to be done.
apps/graphics/twm4nx: Various fixes to get the NxTerm window to come up properly. It does now come up okay, but the system basically loses its mind thereafter. Goods good until some buttons are pressed.
apps/graphics/twm4nx: Simpify application startup.
apps/graphics/twm4nx: Fix some errors in debug statements.
apps/graphics/NXWidgets/: NXWidgets::CNxWidgets: Fix some issues with returned values. On setting the widget size or position, it was returning false if there was no change in size or position. Many places in the code were treating the false return value as an error.
apps/graphics/twm4nx: Fix a couple of errors in the unused resize logic: It was not hiding the resize menu to it appeared as a artifact in the uppler left hand corner. Was calling setSize() on the window instead of getSize(). That was causing errors because the size being set was uninitialized.
apps/graphics/twm4nx: Add missing event generation logic when a window is closed.
Squashed commit of the following:
apps/graphics/twm4nx: Revamp the event system to support notification of external applications when the window is being closed.
apps/graphics/twm4nx: A little NxTerm progress
apps/graphics/twm4nx: Clean up some logic associated with use of multiple Icon Managers.
apps/graphics/twm4nx: Add CNxterm to the build. It is a long way from compiling.
apps/graphics/twm4nx: This resolves the problems noted in the previous commit comments. Window events are now communicated properly to the appliation-specific event handler. Menus now seem to be receiving events and working well.
apps/graphics/twm4nx: Revamp application event handler. Better design but still crashes when a main menu entry is clicked.
apps/graphics/twm4nx: First cut at application window event distribution. Has some issues. Not ready for prime time.
apps/graphics/twm4nx: Add more controls for the events that will be generated on basic window redraw, mouse/keyboard input, and keyboard input.
apps/graphpics/twm4nx: Add a 'Desktop' item to the main menu that will iconify all windows and menus and just show the open desktop.
apps/graphics/twm4nx: Remove some unnecessary twiddling with widget settings.
apps/graphics/twm4nx: Correct an error in how menu windows are created.
apps/graphics/twm4nx: Use button array vs list box for menus.
apps/graphics/twm4nx: Mostly cosmetic stuff.
apps/graphics/twm4ndx: In icon manager, fixing some places where width was used when height was intended. Fixe uninitialized variable.
apps/graphics/twm4nx: The Icon Manager now adds a Main Menu entry that will de-iconify the Icon Manager or raise to the top of the hieararchy if not iconfified. This is useful when there are many open windows.
apps/graphics/twm4nx: In resize operation, don't let window get narrower than the minimum toolbar width.
apps/graphics/twm4nx: Add logic so that the main menu is place at (or near) the position where the background was clicked.
apps/graphics/twm4nx: Better integrate menus and iconifiction: Bringup up a menu is like de-iconifcation, except there is no icon to be erases; taking down a menu is like iconification except that there is no icon to present.
apps/graphics/nxwidgets: Add methods to all windows to query if a window is visible or hidden.
apps/graphics/twm4nx: Use NxWidgets methods which work in all contexts instead of trying to come up with a way to know if a window is displayed through complex flags.
apps/graphics/twm4nx: CWindow: Add a global function that can be used to determine the minimum width of a window. If the window is set to a width smaller than this, then toolbar items will overlap and the toolbar will be corrupted. This is a global function (rather than a method of CWindow) because in some cases, this minimum width must be known before the window is created.
apps/graphics/twm4nx: CMenus now uses CWindows, rather that raw NX windows. This rippled through to many other things due to conflicts between NUL-terminated C strings and NXWidgets::CNxStrings.
apps/graphics/nxwidgets: CWidgetControl::handleLeftClick now returns a value to indicate if the click was actually processed or not. CWidgetControl::pollMouseEvents: Correct return value.
apps/graphics/twm4nx: CBackground::event(): Implement logic to handle a left click on the background and to bring up the main Menu. CWindowEvent: Extend message to distinguish between keyboard and mouse input. Mouse position and buttons now accompany the mouse input data. CMenus: Add methods to query and control the visibility of the menu.
apps/graphics/twm4nx: Additional redesign. Window draggin now sort of works in an unreliable hurky-gurky way. More to be done.
apps/graphics/twm4nx: First cut at redesigned dragging logic
apps/graphics/twm4nx: Replace most usage of NUL-terminated C strings with NXWidgets::CNxString.
apps/graphics/twm4nx: Add initial support for the main menu. The main menu will come up when a left click is performed on the background. The main menu is used for starting applications. The adds the CMainMenu class that implements the main menu and an IApplication interface class the provides th template for how any external C++ application can add itself to the Main Menu.
Still missing is the logic that responds to the meny item selection and sends the event to the Main Menu as well as the logic in the Main Menu that handles the event and either brings up a sub-menu or starts and application.
Things are still basically functional after these changes, but my gut feeling is these changes added some instabilities that will need to be smoothed out.
apps/graphics/twm4nx: Try to improve icon text spacing. Not noticeably better, however.
apps/graphics: Split long icon title on two lines below the icon image.
apps/graphics/twm4nx: Both iconification and de-iconification work.
apps/graphics/twm4nx: Various fixed toward de-iconifying a window. Progress but still not there yet.
graphics/twm4nx/src/window.cxx: Add flags to CWindow initializer to support customization of toolbar buttons and other window properties. Add framework to handle toolbar button presses. Window minimization (aka, iconification) does not work.
graphics/twm4nx/src/input.cxx: Add support to scaling touchscreen. Not needed for the current testing because the touchscreen naturally matches the display size. But will be needed, along with calibration scren, in the future.
graphics/twm4nx/src/ciconmgr.cxx: Correct initial window size and position in the upper righthand corner; Need to fill draw the button array immediately on window creation.
graphics/twm4nx/src/cwindow.cxx: Need to fill the toolbar initially with the widget background color.
Some improvements could be made by anyone. For example, I know the main routine in perform() shall be split into several parts for readability. I apologize in advance for this kind of spaghetti code, but I was short on time to refactor it. Also chunked HTTP transfer encoding would be a nice contribution from anyone interested. It is detected but not yet supported.
apps/graphics/twm4nx: Fix various bugs found in bringup: Re-order object instantiation to account for inter-object dependencies. Correct mq_receive() buffer size. Fix a backward comparison.
apps/graphics/twm4nx: Twm4Nx debug can now be separately enabled so that it does not get overwhelmed by other graphics debug output.
apps/graphics/NxWidgets: Fix a possible deadlock condition when waiting for window geometry data that will never come. Fixed by re-requesting geometry data if we don't already have it.
apps/graphics/twm4nx: Add some debug output.
apps/graphics/twm4nx: Rethink how background events are handled.
apps/grephics/twm4nx: Expermimental organization to capture background events.
include/ and netutils/: Remove references to CONFIG_DISABLE_SIGNALS. Signals can no longer be disabled.
nshlib/: Remove references to CONFIG_DISABLE_SIGNALS. Signals can no longer be disabled.
system/: Remove references to CONFIG_DISABLE_SIGNALS. Signals can no longer be disabled.
testing/: Remove references to CONFIG_DISABLE_SIGNALS. Signals can no longer be disabled.
examples/: Remove references to CONFIG_DISABLE_SIGNALS. Signals can no longer be disabled.
Squashed commit of the following:
apps/nshlib: Remove NSH initialization. Now uses the common apps/netutils/netinit logic (which was cloned from nshlib to begin with).
apps/netutils/netinit: Clone network initialization logic from NSH to this directory so that it can be available for general use.
apps/graphics/twm4nx: Remove Icon Windows; replace with IconWidgets that are draw on the background.
apps/graphics/twm4nx: Add CIconWidget event generation.
apps/graphics/twm4nx: Add event handling logic to CIconWidget.
