Re: GtkImage mouse click signal

[Brian Clark <bc viz tamu edu>]

If I understand what you're looking for, I recently had the same 
question.

Here's what I've got, though it might not be the best way.

First, you have to put your image in an event box, so you can generate 
events when you click on it.  Then you have to connect the event masks 
that you want to be notified about.  The rest is like hooking up a 
button.


    myeventbox = gtk_event_box_new ();
    gtk_widget_show (myeventbox);
    gtk_container_add (GTK_CONTAINER (frame2), myeventbox);
    gtk_widget_add_events(myeventbox, GDK_BUTTON_RELEASE_MASK);
    gtk_widget_add_events(myeventbox, GDK_BUTTON_PRESS_MASK);
    gtk_widget_add_events(myeventbox, GDK_BUTTON1_MOTION_MASK);

    myimage = gtk_image_new_from_pixbuf(/*blah blah*/);
    gtk_widget_show (myimage);
    gtk_container_add (GTK_CONTAINER (myeventbox), myimage);


Hope that makes sense....
