GI.Gtk.Objects.MenuButton

Description

The MenuButton widget is used to display a popup when clicked on. This popup can be provided either as a Menu, a Popover or an abstract MenuModel.

The MenuButton widget can hold any valid child widget. That is, it can hold almost any other standard Widget. The most commonly used child is Image. If no widget is explicitely added to the MenuButton, a Image is automatically created, using an arrow image oriented according to MenuButton:direction or the generic “open-menu-symbolic” icon if the direction is not set.

The positioning of the popup is determined by the MenuButton:direction property of the menu button.

For menus, the Widget:halign and Widget:valign properties of the menu are also taken into account. For example, when the direction is ArrowTypeDown and the horizontal alignment is AlignStart, 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

  • halign = center

  • halign = end

Direction = Up

  • halign = start

  • halign = center

  • halign = end

Direction = Left

  • valign = start

  • valign = center

  • valign = end

Direction = Right

  • valign = start

  • valign = center

  • valign = end

CSS nodes

GtkMenuButton has a single CSS node with name button. To differentiate it from a plain Button, it gets the .popup style class.

new

menuButtonNew Source #

Arguments

Returns: The newly created MenuButton widget

Creates a new MenuButton widget with downwards-pointing arrow as the only child. You can replace the child widget with another Widget should you wish to.

Since: 3.6

setAlignWidget

menuButtonSetAlignWidget Source #

Arguments

:: (HasCallStack, MonadIO m, IsMenuButton a, IsWidget b) 
=> a

menuButton: a MenuButton

-> Maybe b

alignWidget: a Widget

-> m () 

Sets the Widget to use to line the menu with when popped up. Note that the alignWidget must contain the MenuButton itself.

Setting it to Nothing means that the menu will be aligned with the button itself.

Sets the direction in which the popup will be popped up, as well as changing the arrow’s direction. The child will not be changed to an arrow if it was customized.

If the does not fit in the available space in the given direction, GTK+ will its best to keep it inside the screen and fully visible.

If you pass ArrowTypeNone for a direction, the popup will behave as if you passed ArrowTypeDown (although you won’t see any arrows).

Since: 3.6
