>>>>>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.
