Re: [gtkmm] itīs driving me mad ... (replacing contents of VBox)

Hi Martin,

thx for your reply.

My VBox is part of a scrolled window.
I just donīt know how to remove a widget
from a scrolled window...

To follow your hint I do:

myBox = Gtk::manage(new Gtk::VBox());
myBox->pack_start(widget1);
myBox->pack_start(widget2);
myBox->pack_start(widget3);
m_scrolledParamWindow.add(*myBox);
show_all();

Then I should do:

m_scrolledParamWindow.add(*myNewBox);
myBox->pack_start(widget4);
myBox->pack_start(widget5);
myBox->pack_start(widget6);
// I should delete myBox from scrolledWindow
m_scrolledParamWindow.add(*myNewBox);
show_all();
