Overview

The actions are an alternative way to perform operations in a TRichViewEdit editor for FireMonkey. The TRVWidget component provides the same operations as the actions, as well as many additional ones.

Unlike actions for VCL and Lazarus, FireMonkey actions do not work with the editor that currently has the input focus. The editor must be specified explicitly in the ControlPanel.Editor property.

An important requirement for all such actions is that they must be placed in the TActionList assigned to the ActionList property of a TRVControlPanel component. Only in this case are the action states (Enabled and Checked properties) updated correctly.
