Dear all,

I need to create a modal child window.  
So far I use gtk\_window, but it has one problem

# usually I have _self.modal = true_ in initialize method and \*self.modal

false\* in close method.  
problem is close method doesn’t work if the child window is closed by  
clicking x button at the frame,  
so if a user click it, child window disappear but modal state doesn’t  
change to false so parent window can’t be accessed

so my question is,

is it the right way to create a modal child window, if not, what widget  
should I use?  
or  
if it is, what event can I use for changing modal state before close,  
I already use \*delete\_event _and_ destroy \*but it doesn’t work

Thanks

When I need a modal window, I use Dialog:

dialog=Gtk::Dialog::new(“Title”,@parent\_window,Gtk::Dialog::MODAL)

I pack dialog.vbox with whatever I want to show, and I add one or more  
buttons - for example, if I just want the user to close the window I  
write:

dialog.add\_button(‘CLOSE’,Gtk::Dialog::RESPONSE\_CANCEL)  
dialog.signal\_connect(‘response’) do |w,r|  
dialog.destroy()  
end

and I complete with

dialog.show\_all()

I hope this helps

Thanks  
I manage to get it right using dialog like your suggestion, although  
many  
part of code needs to change
