Re: Label on a button - bit more complicated than I thought.

[Harring Figueiredo <harringf yahoo com>]

 This is a bit more complicated than I thought.

 I looked into the gtktoolbar.c source code. ( Gtk 1.2.10)

 I noticed that the toolbar_append func. calls the toolbar_insert func. It then
creates a GtkToolbarChild widget. Then it sets the widget's child to the type
it was passed in.

 Here is the pseudo code:

===========
  Child = new GtkToolbarChild.
  if type is GTK_TOGGLE_BUTTON, then  set 
  child -> widget = new Toggle button.
  if label text != null, child->label = new Label(label text)  <===== And here
is the problem. The label is set on this GtkToolbarChild object, and not on the
togglebutton itself.
  and then they  return the child->widget -- wich is the toogle button. But the
label "stays" behind.

===== End pseudo code.

  How the heck  I am going to get a reference to the object that holds the
label is beyond me, since this child GtkToolbarChild is "private".

   this is going to be fun !!!!

Any takers on the search for the solution ??

Thanks again.
