>>>>>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. _____ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Gautam Ravi Sent: Friday, February 29, 2008 12:11 PM To: [email protected] Subject: Re: Button from an image (round Button) 2008/2/28 Demetris Zavorotnichenko <[EMAIL PROTECTED]>: 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 ? _____ From: Gautam Ravi [mailto:[EMAIL PROTECTED] Sent: Thursday, February 28, 2008 3:19 PM To: Demetris Zavorotnichenko Cc: [email protected] Subject: Re: Button from an image (round Button) 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. -- Regards Gautam 2008/2/27 Demetris Zavorotnichenko <[EMAIL PROTECTED]>: 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.
