Description
Determines whether an object can be inserted into a container.
Vcl.ComCtrls.TToolButton.ValidateContainer inherits from System.Classes.TComponent.ValidateContainer. All content below this line refers to System.Classes.TComponent.ValidateContainer.
Determines whether an object can be inserted into a container.
ValidateContainer is called by a component when it is about to be inserted into a container object. By default, ValidateContainer calls the ValidateInsert method of the component specified by the AComponent parameter.
Descendent components can override ValidateContainer to disallow a component from being inserted into specific containers. To disallow an insertion, raise an exception in the derived method.
