Re: can anybody help with bebugging a little displaying program?

nw

the second argument is the drawable, ie pixmap. the third is the GC
which can be the window style your gonna put the pixmap in.

So you might use:

gdk_pixbuf_render_to_drawable(pixbuf, pixmap,
  window->style->fg_gc[GTK_STATE_NORMAL],
  sx,sy,dx,dy,w,h,GDK_RGB_DITHER_NORMAL,0,0);

alternatively you can create a default gc style for the pixmap and use
that for the second argument.

ps- yep i got them really confused. :(

Hi, there,

do u mean I should use:

GtkPixmap *pixmap;

pixmap=gtk_pixmap_new();
gdk_pixbuf_render_to_drawable (pixbuf, ???,???, 0, 0,0,0,

but how can I fill in the 2nd and 3rd arguments for
gdk_pixbuf_render_to_drawable ?

sorry, I am really new in GTK, thank you so much!
