Hi,
I dont understand the code of this function : gdk_drawable_get_image
the back trace of gdb shows that :
#0 gdk_drawable_real_get_composite_drawable (drawable=0x482e558, x=0, y=0,
width=359, height=322, composite_x_offset=0xbfffe428,
composite_y_offset=0xbfffe42c) at gdkdraw.c:1189
#1 0x0050ae20 in gdk_drawable_copy_to_image (drawable=0x6269108, image=0x0,
src_x=0, src_y=0, dest_x=0, dest_y=0, width=359, height=322) at
gdkdraw.c:1057
#2 0x0050b008 in gdk_drawable_get_image (drawable=0x6269108, x=0, y=0,
width=359, height=322) at gdkdraw.c:1150
when I check "gdk_drawable_real_get_composite_drawable", I see that only
drawable is returned whereas I need to return a part of drawable. Am I wrong
? if not, How can I return the drawable according to x, y, width, height
values ?
static GdkDrawable*
gdk_drawable_real_get_composite_drawable (GdkDrawable *drawable,
gint x,
gint y,
gint width,
gint height,
gint *composite_x_offset,
gint *composite_y_offset)
{
g_return_val_if_fail (GDK_IS_DRAWABLE (drawable), NULL);
*composite_x_offset = 0;
*composite_y_offset = 0;
return g_object_ref (drawable);
}
Best regards,
Malik
