I'm a bit rusty on C++ namespaces but I think that Gtk::manage and manage are the same here...

DocumentProperties inherits from UI::Widget::Panel, which inherits Gtk::VBox. As such, you can access stuff in the Gtk (or UI::Widget) namespace without using the prefix.

If you try to write your own code (which *doesn't* inherit a Gtk:: class) then you can't access Gtk namespace stuff without putting "Gtk::" on the front.

I suspect you have a similar problem with Gtk::ButtonBox but it's hard to tell without seeing the troublesome code.

Can someone with stronger C++-fu confirm?

What is the difference between manage and Gtk::manage ?

ui/dialog/document-properties.cpp:290 Gtk::HBox *space = manage (new Gtk::HBox); ui/dialog/document-properties.cpp:95 _page_page(Gtk::manage(new UI::Widget::NotebookPage(1, 1, true, true))),

Use of manage in my own code produces ‘manage’ was not declared in this scope even when every head has been included from the dp code. very odd.

I'm also having trouble with ButtonBox:

error: no matching function for call to ‘Gtk::ButtonBox::ButtonBox()’ even with include gtkmm/buttonbox.h

What is going on?
