Action.Value (gb.qt4)

Returns or sets the toggle value of all controls associated with an action.

The effect depends on the control:

• If the control is a true toggle control, like a ToggleButton, or a ToolButton with its Toggle property set, then its value is just set or unset.

• If the control is a SidePanel, a ToolBar, or a Window, then the control's Visible property is set instead.
