A graphics example using pre-window frame buffers. The example shows three
|
||
|
|
windows containing text moving around, crossing each other from above and from
|
||
|
|
_below_. The example application is NOT updating the windows any anyway! The
|
||
|
|
application is only changing the window position. The windows are being updated
|
||
|
|
from the per-winidow framebuffers automatically.
|
||
|
|
|
||
|
|
This example is reminiscent of Pong: Each window travels in straight line until
|
||
|
|
it hits an edge, then it bounces off. The window is also raised when it hits the
|
||
|
|
edge (gets focus). This tests all combinations of overap.
|
||
|
|
|
||
|
|
**Note**: A significant amount of RAM, usually external SDRAM, is required to
|
||
|
|
run this demo. At 16bpp and a 480x272 display, each window requires about 70Kb
|
||
|
|
of RAM for its framebuffer.
