BTW, I am just trying to get icons, but there is strange problem:

I am getting only the sort of alpha channel (no colors and perhaps that alpha is one of channels).

Code fragments used are:

		ImageDraw iw(cx + 2 * margin, cy + 2 * margin);
		iw.DrawRect(0, 0, cx + 2 * margin, cy + 2 * margin, back);
		static G_obj *cm = GDK().gdk_x11_colormap_foreign_new(
			GDK().gdkx_visual_get(XVisualIDFromVisual(Xvisual)), Xcolormap);
		G_obj *gw = GDK().gdk_pixmap_foreign_new(iw.GetDrawable());
		GDK().gdk_drawable_set_colormap(gw, cm);


(above is common for painting widget elements too, so there most likely is not problem).

				G_obj *b = GTK().gtk_widget_render_icon(widget, detail, state, NULL);
				GDK().gdk_draw_pixbuf(gw, NULL, b, 0, 0, 0, 0, -1, -1, shadow, 0, 0);
				GOBJ().g_object_unref(b);


(I am iterating state and shadow using several values to investigate the issue, all of them are just alphas...)

Any ideas?

Looking into the API docs, it should be:
				GdkPixbuf *b = GTK().gtk_widget_render_icon(widget, detail, state, NULL);
				GDK().gdk_draw_pixbuf(gw, NULL, b, 0, 0, 0, 0, -1, -1, shadow, 0, 0);
				GOBJ().g_object_unref(b);

and widget has to be != NULL, but I think this is the case. Otherwise one should call gdk_drawable_set_colormap() on b again.

As I am basically redefining the whole interface in U++/.dli and I am using it in just single .cpp file, I have simplified it by "merging" all GTK/GDK/GOBJ pointer types into single one - G_obj (defined in U++).

When I set the font size to "8", the font is different in U++ and Ubuntu. Therefore I tried to alter the code to

	Draw::SetStdFont(Font(fontname, (fontheight * xdpi + 512*72) / (1024*72)));


(rounding the value). This seems to work OK for me, please check with your platforms...

BTW, what was the problem with the pixbuf.

Edit: Size is ok, but I always get default font Arial.

"prototype" widget was set into "insensitive" state for some reason (most likely as result of fact that our hacking of GTK to make it display things for us is really very fragile). Therefore it returned "insensitive" map.

What font have you set? (Just name).

It is simply called "Sans", but it does matter what font I choose, it is always Arial in theIDE even after restarting theIDE.

Indeed, going DejaVu Sans -> DejaVu Serif for the GTK default font has no effect on upp apps Confused

In Draw/Draw.h there are some case sensitive issues for Linux compiles.

#define DLIMODULE GTK
#define DLIHEADER <draw/gtk.dli>
#include <Core/dli_header.h>

#define DLIMODULE GDK
#define DLIHEADER <draw/gdk.dli>
#include <Core/dli_header.h>

#define DLIMODULE GOBJ
#define DLIHEADER <draw/gobj.dli>
#include <Core/dli_header.h>


should be

#define DLIMODULE GTK
#define DLIHEADER <Draw/gtk.dli>
#include <Core/dli_header.h>

#define DLIMODULE GDK
#define DLIHEADER <Draw/gdk.dli>
#include <Core/dli_header.h>

#define DLIMODULE GOBJ
#define DLIHEADER <Draw/gobj.dli>
#include <Core/dli_header.h>

Well I downloaded last night from the dupp-developent 611-dev4 (from Nov 27) and this was the problem I ran into. It's easy to check for yourself.
