Description

Note

This widget is available in PyGTK 2.22 and above.

gtk.OffscreenWindow is strictly intended to be used for obtaining snapshots of widgets that are not part of a normal widget hierarchy. It differs from gtk.Widget.get_snapshot() in that the widget you want to get a snapshot of need not be displayed on the user's screen as a part of a widget hierarchy. However, since gtk.OffscreenWindow is a toplevel widget you cannot obtain snapshots of a full window with it since you cannot pack a toplevel widget in another toplevel.

The idea is to take a widget and manually set the state of it, add it to a gtk.OffscreenWindow and then retrieve the snapshot as a gtk.gdk.Pixmap or gtk.gdk.Pixbuf.

gtk.OffscreenWindow derives from gtk.Window only as an implementation detail. Applications should not use any API specific to gtk.Window to operate on this object. It should be treated as a gtk.Bin that has no parent widget.

When contained offscreen widgets are redrawn, gtk.OffscreenWindow will emit a "damage-event" signal.

Constructor

    gtk.OffscreenWindow()

Returns :

A pointer to a gtk.Widget

Note

This constructor is available in PyGTK 2.22 and above.

Creates a toplevel container widget that is used to retrieve snapshots of widgets without showing them on the screen. For widgets that are on the screen and part of a normal widget hierarchy, gtk.Widget.get_snapshot can be used instead.

Methods

gtk.OffscreenWindow.get_pixmap

    def get_pixmap()

Returns :

A gtk.gdk.Pixmap, or None.

Note

This method is available in PyGTK 2.22 and above.

Retrieves a snapshot of the contained widget in the form of a gtk.gdk.Pixmap.

gtk.OffscreenWindow.get_pixbuf

    def get_pixbuf()

Returns :

A gtk.gdk.Pixbuf, or None.

Note

This method is available in PyGTK 2.22 and above.

Retrieves a snapshot of the contained widget in the form of a gtk.gdk.Pixbuf.
