[glade--]Re: [gtkmm] Double Window Hell

Hi Dennis,

at first I thought you were using glademm (the sample code looked much 
like the generated code by glademm). But now on second reading I realize 
that this is not the case (kit is not the name used by glademm for the 
main loop and there's no UI base class).

Libglademm has a method to specify the toplevel widget to create 
(glademm uses this variant but I don't remember it easily). Try this 
one. IIRC of course.

The following might be good for the bit bucket but would have been the 
correct answer if you had used glademm.

It makes sense. What Murray does not know is that you use glade-- to 
generate the skeleton for your program.

And since glade-- can not know better it creates sample code for every 
window you define. It is your task to fill in the callback flesh and to 
decide which window to generate during main and which during a callback 
(move the widget include/creation code into the appropriate callback).

So your problem is not with libglademm, your problem lies within a 
missing tutorial for libglademm projects generated by glademm.

Feel free to ask more ([email protected] might be better suited for 
this task) [Murray reads it, too].

glademm choses the first window as the main window (which's destruction 
will end the main loop). Alter the sample code within main and it will 
do what you want.
