fsleyes.actions.togglecontrolpanel

This module provides the ToggleControlPanelAction class, an action intended for use by ViewPanel classes to manage the addition/removal of control panels.

class fsleyes.actions.togglecontrolpanel.ToggleControlPanelAction(overlayList, displayCtx, func, instance, cpType)[source]

Bases: fsleyes.actions.base.ToggleAction

The ToggleControlPanelAction class is an action which is intended to augment ViewPanel actions which add/remove a control panel.

The ToggleControlPanelAction keeps track of the ViewPanel state, and updates its own ToggleAction.toggled property whenever its designated control panel is added/removed from the ViewPanel.

This sounds a bit silly, but is necessary to ensure that any bound widgets (most likely menu items) are updated whenever the control panel managed by a ToggleControlPanelAction is added/removed.
