Struct gtk4::WindowControls[][src]

pub struct WindowControls(_);
Expand description

WindowControls shows window frame controls.

Typical window frame controls are minimize, maximize and close buttons, and the window icon.

An example GtkWindowControls

WindowControls only displays start or end side of the controls (see property::WindowControls::side), so it’s intended to be always used in pair with another WindowControls for the opposite side, for example:

<object class="GtkBox">
  <child>
    <object class="GtkWindowControls">
      <property name="side">start</property>
    </object>
  </child>

  ...

  <child>
    <object class="GtkWindowControls">
      <property name="side">end</property>
    </object>
  </child>
</object>

CSS nodes

windowcontrols
├── [image.icon]
├── [button.minimize]
├── [button.maximize]
╰── [button.close]

A WindowControls’ CSS node is called windowcontrols. It contains subnodes corresponding to each title button. Which of the title buttons exist and where they are placed exactly depends on the desktop environment and property::WindowControls::decoration-layout value.

When property::WindowControls::empty is true, it gets the .empty style class.

Accessibility

WindowControls uses the AccessibleRole::Group role.

Implementations

Creates a new WindowControls.

side

the side

Returns

a new WindowControls.

Creates a new builder-pattern struct instance to construct WindowControls objects.

This method returns an instance of WindowControlsBuilder which can be used to create WindowControls objects.

Gets the decoration layout of this WindowControls.

Returns

the decoration layout or None if it is unset

Gets whether the widget has any window buttons.

Returns

true if the widget has window buttons, otherwise false

Gets the side to which this WindowControls instance belongs.

Returns

the side

Sets the decoration layout for the title buttons.

This overrides the property::Settings::gtk-decoration-layout setting.

The format of the string is button names, separated by commas. A colon separates the buttons that should appear on the left from those on the right. Recognized button names are minimize, maximize, close and icon (the window icon).

For example, “icon:minimize,maximize,close” specifies a icon on the left, and minimize, maximize and close buttons on the right.

If property::WindowControls::side value is PackType::Start, self will display the part before the colon, otherwise after that.

layout

a decoration layout, or None to unset the layout

Determines which part of decoration layout the WindowControls uses.

See property::WindowControls::decoration-layout.
