|
||
* @short_description: A widget that shows a popup when clicked on
|
||
* @title: GtkMenuButton
|
||
*
|
||
* The #GtkMenuButton widget is used to display a popup when clicked on.
|
||
* This popup can be provided either as a #GtkMenu, a #GtkPopover or an
|
||
* abstract #GMenuModel.
|
||
*
|
||
* The #GtkMenuButton widget can hold any valid child widget. That is, it
|
||
* can hold almost any other standard #GtkWidget. The most commonly used
|
||
* child is #GtkImage. If no widget is explicitely added to the #GtkMenuButton,
|
||
* a #GtkImage is automatically created, using an arrow image oriented
|
||
* according to #GtkMenuButton:direction or the generic "view-context-menu"
|
||
* icon if the direction is not set.
|
||
*
|
||
* The positioning of the popup is determined by the #GtkMenuButton:direction
|
||
* property of the menu button.
|
||
*
|
||
* For menus, the #GtkWidget:halign and #GtkWidget:valign properties of the
|
||
* menu are also taken into account. For example, when the direction is
|
||
* %GTK_ARROW_DOWN and the horizontal alignment is %GTK_ALIGN_START, the
|
||
* menu will be positioned below the button, with the starting edge
|
||
* (depending on the text direction) of the menu aligned with the starting
|
||
* edge of the button. If there is not enough space below the button, the
|
||
* menu is popped up above the button instead. If the alignment would move
|
||
* part of the menu offscreen, it is “pushed in”.
|
||
*
|
||
* ## Direction = Down
|
||
*
|
||
* - halign = start
|
||
*
