>>>>>gtk_widget_shape_combine_mask(GTK_WIDGET(button),mask, ...);
doesn't work like this with errors
>>>>gdk_window_shape_combine_mask (button->window, mask, ...);
doesn't compile like this (passing argument 1 form incompatible pointer type)
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.
