Implemented Interfaces

HildonStackableWindow implements AtkImplementorIface and GtkBuildable.

Description

HildonStackableWindow is a top-level window that can be stacked on top of others. It is derived from HildonWindow. Applications that use stackable windows are organized in a hierarchical way so users can go from any window back to the previous one or directly to the stack's root window.

The user can only see and interact with the window on top of the stack. Although all other windows are mapped and visible, they are obscured by the topmost one so in practice the user will see the whole stack as if it was a single window.

To add a window to the stack, just use gtk_widget_show(). The previous one will be obscured by the new one. When the new window is destroyed, the previous one will appear again.

Alternatively, you can remove a window from the top of the stack without destroying it by using gtk_widget_hide(). The window will be hidden and the previous one will appear automatically.

It is important to note that all HildonStackableWindows on a stack are always mapped and visible (from the Gtk point of view) and all visible HildonStackableWindows are always on a stack.
