TTabControl.Enabled property
Determines whether the control responds to mouse or keyboard input.
Declaration
property Enabled:;Description
Enabled is a
Boolean property which indicates whether
the control can respond to focus, input, or mouse events. The default value
for the property is
True. When Enabled is set to
False, the
control is displayed with a "grayed-out" appearance. It is unable to receive
input focus, handle keyboard navigation or input, respond to mouse click
events, or execute its Action.
Changing the value for the property causes additional actions to be performed. EnabledChanging is called to signal any chtOnEnabledChanging control handlers assigned for the control. The property value is updated, and a CM_ENABLEDCHANGED control message is dispatched for the control. The EnabledChanged method is called to signal any chtOnEnabledChanged control handlers for the control.
Use IsEnabled to check the effective enabled state for both the control and its Parent control (when assigned).
This description is the one of Controls.TControl.Enabled.
