GtkIconTheme doesn't scale icons beyond the size specified in the theme anymore. This can result in arbitrarily large menu items when a theme only provides large icons. Force icons to always be 16x16 to ensure that menu items always have the same height. https://bugzilla.gnome.org/show_bug.cgi?id=741259

|
|
* @Short_description: A menu item with an icon
|
|
* @Title: GtkImageMenuItem
|
|
*
|
|
* A GtkImageMenuItem is a menu item which has an icon next to the text label.
|
|
*
|
|
* This is functionally equivalent to:
|
|
*
|
|
* |[<!-- language="C" -->
|
|
* GtkWidget *box = gtk_box_new (GTK_ORIENTATION_HORIZONTAL, 6);
|
|
* GtkWidget *icon = gtk_image_new_from_icon_name ("folder-music-symbolic, GTK_ICON_SIZE_MENU);
|
|
* GtkWidget *label = gtk_label_new ("Music");
|
|
* GtkWidget *menu_item = gtk_menu_item_new ();
|
|
*
|
|
* gtk_container_add (GTK_CONTAINER (box), icon);
|
|
* gtk_container_add (GTK_CONTAINER (box), label);
|
|
*
|
|
* gtk_container_add (GTK_CONTAINER (menu_item), box);
|
|
*
|
|
* gtk_widget_show_all (menu_item);
|
|
* ]|
|
|
*
|
|
* Note that the user may disable display of menu icons using
|
|
* the #GtkSettings:gtk-menu-images setting, so make sure to still
|
|
* fill in the text label. If you want to ensure that your menu items
|
|
* show an icon you are strongly encouraged to use a #GtkMenuItem
|
|
* with a #GtkImage instead.
|
|
*
|
|
* #GtkImageMenuItem has been deprecated since GTK+ 3.10. If you want to
|
|
* display an icon in a menu item, you should use #GtkMenuItem and pack a
|
|
* #GtkBox with a #GtkImage and a #GtkLabel instead. You should also consider
|
|
* using #GtkBuilder and the XML #GMenu description for creating menus, by
|
|
* following the [GMenu guide][https://developer.gnome.org/GMenu/]. You should
|
|
* consider using icons in menu items only sparingly, and for "objects" (or
|
|
* "nouns") elements only, like bookmarks, files, and links; "actions" (or
|
|
* "verbs") should not have icons.
