Re: Alt+Button click and events

["richard boaz" <ivor boaz gmail com>]

not sure what's could be going wrong since you didn't supply any code, but...

first, see the accelerator documentation:

http://library.gnome.org/devel/gtk/stable/gtk-Keyboard-Accelerators.html#gtk-accelerator-set-default-mod-mask

and to "see" if the ALT key is pressed, in your mouse callback:

gboolean mouse(GtkWidget *widget, GdkEventButton *event, gpointer nil)
{
    static guint    modifiers = gtk_accelerator_get_default_mod_mask();
    gboolean  ALTkeyActive;

    ALTkeyActive = ((event->state & modifiers) == GDK_MOD1_MASK) ? TRUE : FALSE;
    switch (ALTkeyActive)
    {
        case TRUE:   // do something when pressed
        break;
        case FALSE:  // do something when not pressed
        break;
    }
}

cheers,

richard

I have an odd feeling that this is a stupid question because I'm overlooking something very obvious, but does Alt+Mouse button click have any special meaning in Gtk?

What I mean to say is, I have an application where I draw to a drawing area widget, and also handle various events for it "by hand" via the button-press-event and button-release-event signal, among others. This all works rather fine, but if the Alt button is pressed, my event handlers doesn't seem to "see" the button presses. Is there any obvious reason for this?
