TCDButton.Action property

Declaration

property Action:;

Description

Not described here; this is what TControl.Action says of it:

The Action associated with the control.

Action is a TBasicAction property with the action assigned to the control. The value for the property is read from the Action property in ActionLink (when assigned). If ActionLink has not been assigned, the property value is Nil.

Assigning an action to the property causes ActionLink to be updated. If the new property value is Nil, the TControlActionLink instance in ActionLink is freed and control style flags are updated to remove the value csActionClient.

Conversely, a TControlActionLink instance is created for a non-empty action assignment. Its OnChange event handler is set to the private DoActionChange method in the class instance. Control style flags are updated to include the value csActionClient.

Action is used in the Click method to signal its OnExecute event handler when assigned and enabled. Preference is given to the OnClick in the control (when assigned).

Values in the Caption, Enabled, HelpType, and Hint properties can be linked to the Action through the property values in the ActionLink.

Use AssignTo to copy property values in the control to a TCustomAction instance.
