protected procedure TWinControl.SetChildZPosition( |
const AChild: TControl; |
const APosition: Integer |
); |
AChild |
|
Control to locate and move in the method. |
APosition |
|
New ordinal position for the control in the Controls property. |
SetChildZPosition repositions the child control in AChild in the display order for the child Controls in the class instance. No actions are performed in the method when:
APosition contains the new relative display order on the Z-axis for the specified child control. A value in APosition must be in the range allowed in Controls (0..Controls.Count-1). Smaller values in APosition move the child control towards the front or top of the display order. Larger values move the child control towards the bottom or back of the display order.
SetChildZPosition calls the Move method in Controls to change the ordinal position for the specified control in the list.
If AChild is a TWinControl descendant, the SetChildZPosition method in the widgetset class is used to notify the child controls which have a valid handle. If AChild is a TControl instance, its InvalidateControl method is called to redraw the control using its visibility and opacity settings.
SetChildZPosition is used to implement the SetControlIndex method.
