TAction.OnExecute

Event called when action is executed.

Declaration

Source position: actnlist.pas line 245

published property TAction.OnExecute;

Description

OnExecute is the event triggered when the action is activated (executed). The event is triggered e.g. when the user clicks e.g. on a menu item or a button associated to the action. The application programmer should provide a OnExecute event handler to execute whatever code is necessary when the button is pressed or the menu item is chosen.

Note that assigning an OnExecute handler will result in the Execute method returning a True value. Predefined actions (such as dataset actions) will check the result of Execute and will not perform their normal task if the OnExecute handler was called.

Since version 1.1 setting OnExecute no longer sets the owner's OnClick. You can now specify an event for the action and a more specific OnClick for control and both are called. OnClick is called before OnExecute.
