That’s ok now, I have found
something better to suit my needs for now.
I do a pixbuf animation on the keypad
panel and take out the pointer location to change the frame content.
I think this wat I can do more than just
display the buttons, but also animate them J
I appreciate the help Ravi.
Your suggestion will help me in another aspect of my project.
Once again I appreciate the help on this.

doesn't work like this with errors

doesn't compile like this (passing
argument 1 form incompatible pointer type)
Use gdk_window_shape_combine_mask
(GTK_WIDGET (button)->window, mask, ...);
I wanted to ask something else.
I want to create a keypad with 34 buttons
So I create the buttons in a loop.
And assign a callback function to the button
But I have only 1 callback function and 34 buttons so how do
I know which button has been pressed in that callback ?
I have to create a separate callback function for each button
? and create the buttons separately? Or can I have an array of this buttons ?
but then with an array I still have to have a separate callback ? please help
out.

I have done it like this: gtk_widget_shape_combine_mask(GTK_WIDGET(button->window),mask,0,0);
You are
type-casting a GdkWindow to a GtkWidget, which you cannot do.
In this case its sufficient if you do
gtk_widget_shape_combine_mask(GTK_WIDGET(button),mask, ...);
or
gdk_window_shape_combine_mask (button->window, mask, ...);
It compiles
But when I run the application I get:
gtk_widget_shape_combine_mask: assertion 'GTK_IS_WIDGET
(widget)' failed
What am I doing wrong?
How should the function look like ?
Hi,
GtkButton has its own GdkWindow. It can be accessed like GTK_WIDGET
(button)->window.
You can do the "shape_combine_mask" for
the GtkButton's window also. See that "shape_combine_mask" is done
when it is realized.

Hi
everyone.
Forgive
me if my question is going to sound silly. But I'm new to GTK so I have to ask.
I
want to create a button that would not be as a normal button, but with a shape
I have from a PNG image(with transparency)
I
have tried to do "shape_combine_mask" , created the masks, but it seems
this works only for windows.
But
I need a button with the shape from a PNG image and if I press it I would call
a function so the button would have roll_over, or atleast "clicked"
signals. Plus I want to make a bunch of them to create a keypad so I would have
to move them and arrange them in a loop.
How
could I do this ?
PLS
help out.
Yours
truly, Demetris Z.
