Widget Overview
- Widget Hierarchy
- Widgets without Windows
The general steps to creating a widget in Inti are:
- Create a new widget on the heap by calling operator new, then
- either, connect all the signals and events you wish to handle
- or, derive a new class from an existing widget class and override
it's virtual signal handlers.
- Set the attributes of the widget.
- Pack the widget into a container using the appropriate call to
Gtk::Container::add() or Gtk::Box::pack_start().
- Call Gtk::Widget::show() to let GTK know that you are done
setting the attributes and the widget is ready to be displayed.
You may also use Gtk::Widget::hide() to make it
disappear again. The order in which you show the widgets is not
important, but I suggest showing the window last so the whole window
pops up at once rather than seeing the individual widgets come up on
the
screen as they're formed. The children of a widget (a window is a
widget
too) will not be displayed until the window itself is shown using the
Gtk::Widget::show() method.
Widget Hierarchy
For your reference, here is the class hierarchy tree
used to implement widgets. Deprecated widgets and auxiliary classes
have
been omitted.
