Hello,
I've been playing around with some of the apps in the directfb-
examples package learning how directfb works. I tried to add window
resize support to df_window, and now the application segfaults when
resizing. In its origonal form, the windows simply disapear when
resizing. Can someone please tell me if I'm resizing correctly, or
the proper way to resize if not?
Any help is much appreciated.
Thanks,
Ryan Burns
Here is the relevant code:
df_window.c
//draw rectangle with video support removed
void draw_window2()
{
int width;
int height;
window_surface2->GetSize(window_surface2, &width, &height);
window_surface2->SetColor( window_surface2, 0x00, 0x30, 0x10,
0xc0 );
window_surface2->DrawRectangle( window_surface2, 0, 0, width,
height );
window_surface2->SetColor( window_surface2, 0x80, 0xa0, 0x00,
0x90 );
window_surface2->FillRectangle( window_surface2, 1, 1, width-2,
height- -> 2 );
window_surface2->Flip( window_surface2, NULL, 0 );
}
[snip]
//switch inside while loop in main()
switch (evt.type) {
...
case DWET_SIZE:
if (active == window1)
draw_window1();
if (active == window2)
draw_window2();
break;
