Method GTK2.FileChooser()->set_preview_widget()


Method set_preview_widget

GTK2.FileChooser set_preview_widget(GTK2.Widget widget)

Description

Sets an application-supplied widget to use to display a custom preview of the currently selected file. To implement a preview, after setting the preview widget, you connect to the "update-preview" signal, and call get_preview_filename() or get_preview_uri() on each change. If you can display a preview of the new file, update your widget and set the preview active using set_preview_widget_active(). Otherwise, set the preview inactive.

When there is no application-supplied preview widget, or the application- supplied preview widget is not active, the file chooser may display an internally generated preview of the current file or it may display no preview at all.
