TControl.Visible

Allows the control, and all of its children, to be displayed or hidden.

Declaration

Source position: controls.pp line 1825

public property TControl.Visible : Boolean read FVisible write SetVisible stored IsVisibleStored default True;

Visible is set to True by Show, or to False by Hide. Calling these methods is equivalent to setting the Visible property.

Remark:

Reading the Visible property does not take into account control's parent visibility. Use the IsVisible method to get the real visibility.

TControl.IsVisible		Gets the effective visibility for the control and all of its Parent controls.
TControl.Show		Makes the control visible by setting Visible to True.
TControl.Hide		Hides the control by setting the Visible property to False.
