Hi,
this does not work because the window does not exist yet; it is only
created once you start the event loop.
A possible solution is to do your drawing right after initialization.
First, you must include a single-shot callback handler with a timeout of
zero:
lite_enqueue_window_timeout( 0, timeoutfunc, lite_box, 0);
Then, in the callback handler, you can do the drawing like so:
DFBResult timeoutfunc(void *data)
{
LiteBox *lite_box = data;
IDirectFBSurface *test=lite_box->surface;
test->SetColor(test,155,155,155,255);
test->FillRectangle(test,10,10,260,160);
lite_draw_box(lite_box, 0, true);
return DFB_OK;
}
And then you can call the event loop:
lite_window_event_loop( window, 0 );
note that will not be permanent, since the box will simply CLEAR itself
on any redraw.
The correct solution is to overrule the box->Draw function like so:
lite_box->Draw = drawfunc;
and then have a drawfunc like this:
DFBResult drawfunc( struct _LiteBox *lite_box, const DFBRegion *region,
DFBBoolean clear)
{
IDirectFBSurface *test=lite_box->surface;
test->SetColor(test,155,155,155,255);
test->FillRectangle(test,10,10,260,160);
return DFB_OK;
}

Hi,
i have changed the code of checktest.c . I have got one LiteWindow,LiteBox and
just
want to display the LiteBox in LiteWindow with another color. But it does not
work.
I can only see the empty LiteWindow. For help, i would be grateful.
