We used to explicitly map and unmap the child GtkRecentChooserWidget when mapping and unmapping the dialog, respectively. Now that GtkContainer actually unmaps child widgets (instead of avoiding that), we can assume that the child GtkRecentChooserWidget will be unmapped when we want it to be. This fixes a warning from gtk_widget_verify_invariants(), as we were mapping our child widget before calling our parent class' ::map() handler. Bug #659257.

* @Short_description: Displays recently used files in a dialog
|
|
* @Title: GtkRecentChooserDialog
|
|
* @See_also:#GtkRecentChooser, #GtkDialog
|
|
*
|
|
* #GtkRecentChooserDialog is a dialog box suitable for displaying the recently
|
|
* used documents. This widgets works by putting a #GtkRecentChooserWidget inside
|
|
* a #GtkDialog. It exposes the #GtkRecentChooserIface interface, so you can use
|
|
* all the #GtkRecentChooser functions on the recent chooser dialog as well as
|
|
* those for #GtkDialog.
|
|
*
|
|
* Note that #GtkRecentChooserDialog does not have any methods of its own.
|
|
* Instead, you should use the functions that work on a #GtkRecentChooser.
|
|
*
|
|
* <example id="gtkrecentchooser-typical-usage">
|
|
* <title>Typical usage</title>
|
|
* In the simplest of cases, you can use the following code to use
|
|
* a #GtkRecentChooserDialog to select a recently used file:
|
|
* <programlisting>
|
|
* GtkWidget *dialog;
|
|
*
|
|
* dialog = gtk_recent_chooser_dialog_new ("Recent Documents",
|
|
* parent_window,
|
|
* GTK_STOCK_CANCEL, GTK_RESPONSE_CANCEL,
|
|
* GTK_STOCK_OPEN, GTK_RESPONSE_ACCEPT,
|
|
* NULL);
|
|
*
|
|
* if (gtk_dialog_run (GTK_DIALOG (dialog)) == GTK_RESPONSE_ACCEPT)
|
|
* {
|
|
* GtkRecentInfo *info;
|
|
*
|
|
* info = gtk_recent_chooser_get_current_item (GTK_RECENT_CHOOSER (dialog));
|
|
* open_file (gtk_recent_info_get_uri (info));
|
|
* gtk_recent_info_unref (info);
|
|
* }
|
|
*
|
|
* gtk_widget_destroy (dialog);
|
|
* </programlisting>
|
|
* </example>
|
|
*
|
|
* Recently used files are supported since GTK+ 2.10.
