Hello,
I am a newcomer to Gtkmm and this mailing list, I have a question
regarding the use of the reparent command using gtkmm-3.
I am attempting to add several text labels to the MessageDialog. I wish
to position these labels below the dialog-secondary text using a grid
to achieve this. The following snippet of code works but gives the
following warning.
Gtk-WARNING **: Attempting to add a widget with type GtkBox to a container
of type gtkmm__GtkWindow, but the widget is already inside a container of
type GtkBox, please use gtk_widget_reparent()
I understand that the format for the reparent function is
gtk_widget_reparent(original widget,new widget);
I am trying to reparent the MessageDialog's vertical box with my new one
Every attempt I have made so far has failed...
//Snippet of my code
// The true in Messagedialog is becuse the Message string contains pango markup
Gtk::MessageDialog
dialog(*this,Message->c_str(),true,Gtk::MESSAGE_INFO,Gtk::BUTTONS_CLOSE);
// some text labels that I wish to add to the MessageDialog
Gtk::Label *label1 = Gtk::manage(new Gtk::Label("some text"));
Gtk::Label *label2 = Gtk::manage(new Gtk::Label("some more text"));
// then the box and grid I wish to add
Gtk::Grid *grid = Gtk::manage(new Gtk::Grid);
Gtk::Box *vbox = Gtk::manage(new Gtk::Box(Gtk::ORIENTATION_VERTICAL, 0));
vbox = dialog.get_message_area(); // make vbox the new message area
// The next line of code is where I have the problem.
gtk_widget_reparent(???,???); //What do I place here ?
add(*vbox); // add the new vbox
vbox->add(*grid); // then the grid
grid->attach(*label,0,2,1,1); // finally position the labels
grid->attach(*label,1,2,2,1);
dialog.set_secondary_text("secondary text");
vbox->show_all(); // display it
dialog.run();
I would appreciate any pointers on how I can achieve this.
Thank you.
