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 gtkFileChooserGetPreviewFilename or gtkFileChooserGetPreviewUri on each change. If you can display a preview of the new file, update your widget and set the preview active using gtkFileChooserSetPreviewWidgetActive. 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. Since 2.4
