TRVAControlPanel is the component allowing to change settings for RichViewActions

Unit RichViewActions;

Syntax

TRVAControlPanel = class(TComponent)

hmtoggle_arrow1Hierarchy

Description

This component contains properties affecting many RichViewActions.

Main control panel

If an application does not contain TRVAControlPanel on a form, a default control panel is used (accessible as MainRVAControlPanel). If an application contains a single TRVControlPanel on a form, it becomes the main control panel automatically (assigned to MainRVAControlPanel). Another control panel can be made a main one if you call its Activate method.

Linking

All actions and many components in RichViewActions have links to a control panel, including:

TrvCustomAction.ControlPanel

TRVStyleTemplateCombo/ListBox.ControlPanel

If this link is not assigned (nil), the action/component uses the main control panel (see above).
