TButtonControl.Click procedure
Performs actions needed when a click message is handled for the control.
Declaration
procedure Click; overrideDescription
Click is an overridden method in
TButtonControl. Click
calls the
DoOnChange method which signals the
OnEditingDone and
OnChange event handlers (when
assigned).
Click calls the inherited method prior to exit. The inherited method (in TControl) signals either the OnClick event handler or the OnExecute handler in the Action. OnClick is used when Action has not been assigned, or when OnClick contains a handler routine that differs from the one assigned to the OnExecute handler in the Action.
Click can be called in two different usage scenarios. If standard click events have been enabled in ControlStyle, it is called when the left mouse button is released. It can also be called from a private LM_CLICKED message handler in the control when standard click events are not enabled in ControlStyle. This avoids duplicate click notifications when csClickEvents is enabled in ControlStyle and Click is handled when the WMLButtonUp method is executed.
