invalidate() [2/6]

virtual void xtd::forms::control::invalidate ( bool  invalidate_children ) const

virtual

Invalidates a specific region of the control and causes a paint message to be sent to the control. Optionally, invalidates the child controls assigned to the control.

Parameters

invalidate_children

true to invalidate the control's child controls; otherwise, false.

Remarks

Calling the invalidate method does not force a synchronous paint; to force a synchronous paint, call the update method after calling the Invalidate method. When this method is called with no parameters, the entire client area is added to the update region.
