Hello there. I would like to save a series of Pixbuf's as an animated
GIF. I'm wondering if I can use gdk_pixbuf_save() for this. I can't
seem to find out for sure if it supports the GIF format. And even if
it does, I'm not sure how to do the animation stuff. The GIMP can
obviously do this, and I'v
What do you mean by transparent? What is "behind" the drawing area
that you would like to show through?

Ah, I see. Thanks for showing that pitfall, I could easily have done
the same thing.

You should use the GINT_TO_POINTER() macro on your variable. Then use
GPOINTER_TO_INT() to extract the int back out of the pointer.
See this:

This method will work, but only for integers (since poi
Madeningly, it is not included with Fedora, or Mandrake. Fortunately,
on Mandrake at least, it is easy to install with urpmi (assuming
correct repositories are set up). I assume it can also easily be
installed on Fedora with yum.

Here's one way:
1. Create an empty pixmap:
GdkPixmap *pix_work;
pix_work = gdk_pixmap_new(widget->window, xsize, ysize, -1);
2. Draw your pixbuf (which I assume you have already created) onto the pixmap:
gdk_draw_pixbuf(pix_work, NULL, pixbuf, 0, 0, 0,
Hi there. No offense, but I think this question would be more

At first, I would suspect that the use of deprecated widgets could
cause this problem. As it turns out, GtkClist is indeed deprecated
(use GtkTreeView instead). However, GtkEntry is not deprecated, so I
am surprised that it too doesn't work properly. I would go through the
GTK 2.x documentation and
The problem is that, as Tim said, hitting cancel emits a
GTK_RESPONSE_DELETE_EVENT, not a GTK_RESPONSE_CANCEL. So with your
code, if the user hits escape, your if statement will go to the "ok"
part. Here's what you should use instead:
switch (response) {
case GTK_RESPONSE_CANCEL:
The documentation says the action_area is indeed a GtkHButtonBox. I
doubt that you can change this to a GtkVButtonBox, because that is not
the way dialog widgets normally behave. Perhaps, instead, you could
put all the choices as entries in a GtkComboBox. Then simply have the
usual Ok and Cancel bu
Does the .gif file have transparency? If not, try making the
"background" areas of the image transparent, and see what happens.

To convert to greyscale, just look through each pixel, apply the
transformation you mentioned, and then set all three components to
that value:
value = 0.299*Red+0.587*Green+0.114*Blue;
Red = value;
Green = value;
Blue = value;

I don't think you can change the size of the actual button, as this is
determined by the system you are running on. You could perhaps create
your own radio button widget and write custom drawing code for it.

I beleive you can just use gtk_window_set_position () on your main window.
