[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.

The issue isn't with the window NOT appearing. The window that I want to
appear does appear. The problem is that the second window is created
along with my application. Every time I execute my code, two windows
appear where I only want one. Of the two windows that appear, one is my
application, and the other is a blank window with the word "main" in its
title bar. That's the one I'd like to get rid of, but I don't know where
it is coming from. This window also seems to have control of killing the
application. Does this make sense?

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 (glademm-list gnome org might be better suited for this task) [Murray reads it, too].

This is something probably pretty simple, but it is making me quite angry. I've used regular GTK+ before, but this is my first time using gtkmm and also my first libglade(mm) attempt. The problem is that when I execute my code, I get two windows; one that I intended on getting, and one that is just a blank window with the title "main". It appears that the mystery window is dominant, as it is the only one (when it's wm close button is clicked) that will kill the application.

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.

I don't know if the contents of the .glade file is of importance, but it maybe since my code doesn't look much different than the examples that came with the packages. Could it be that the problem lies in the .glade file? Is there any documentation for the gtkmm/libglademm combo? If I ever get this figured out, I might write up a simple tutorial myself.. Something just to get people started using these two packages in unison.
