Hi!

I try to draw part of image in drawing area, but all I get is access violation:

Code: (C)
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22	static gboolean expose_event( GtkWidget widget, GdkEventExpose event ) { gdk_draw_drawable(widget->window, widget->style->white_gc, pixmap, event->area.x, event->area.y, event->area.x, event->area.y, event->area.width, event->area.height); gdk_draw_image(widget->window, widget->style->white_gc, img1, 0,0, 0,0, 50,50); return FALSE; }

First function, where I copy portion of hand-made pixmap works fine, but img1 loaded with gtk_image_new_from_file() fails. Image loaded correcrtly, I can show it, if I use gtk_container_add().

Image is simply 128x128 bmp file.

Can anyone help me?

PS: Yes, I saw demos like images.c, but they use gtk_container_add() instead of gdk_draw_image().

You can draw a GdkImage onto a GtkDrawingArea. Why not just use that or GdkPixbuf?
