Well I have other things on my screen drawn out such as the following:
//this is my window
Main {
..............
...
rect.x = 0; rect.y = 0; rect.w = 320; rect.h = 240; //Screen
dimensions
lite_new_window( NULL, &rect, DWCAPS_NODECORATION,
liteNoWindowTheme, NULL, &screen );
lite_set_window_background_color( screen, white.r, white.g, white.b,
white.a );
lite_hide_cursor();
lite_set_window_opacity( screen, liteFullWindowOpacity );
...
Function1
Function2
...
}
//I am placing this image on one location, and I want to draw on top of it
(you can see the coordinates are similar in the code below)
Function1{
DFBRectangle rect;
LiteImage *image;
/* setup image */
rect.x = 185; rect.y = 4; rect.w = 56; rect.h = 20;
lite_new_image(LITE_BOX(window), &rect, liteNoImageTheme, &image);
lite_load_image( image, "image.png" );
}
//And then I attempt to draw a figure:
Function2{
static IDirectFBSurface *batt = NULL;
static LiteBox *batt_stat = NULL;
static DFBRectangle batt_rect[2];
batt_rect[0].x = 188; batt_rect[0].y = 7; batt_rect[0].w = 47;
batt_rect[0].h = 14;
batt_rect[1].x = 235; batt_rect[1].y = 9; batt_rect[1].w = 3;
batt_rect[1].h = 10;
lite_new_box( &batt_stat, LITE_BOX(window), 188, 7, 50, 14 );
lite_init_box( batt_stat );
batt = batt_stat->surface;
batt->SetColor( batt, green.r, green.g, green.b, green.a ); //green
batt->FillRectangles( batt, batt_rect, 2 );
batt->Flip( batt, NULL, 0 );
}
I have defined green as the following:
static DFBColor green = {0xff, 0x2A, 0xff, 0x02 };
V/R,
Bryan
