BBjWindow::setRepaintEnabled

Description

In BBj 16.00 and higher, this BBjWindow method controls whether program action (such as adding controls or setting attributes of controls) will cause a repaint on the window.

Syntax

Return Value	Method
void	setRepaintEnabled(boolean `enabled`)

Parameters

Parameter	Description
enabled	Specifies whether repaints should be enabled. By default, enabled is true (1). true (1) = Repaints are enabled. false (0) = Repaints are not enabled.

Return Value

None.

Remarks

After setRepaintEnabled(0) has been called, adding controls or modifying controls will not cause the window to be repainted. Calling setRepaintEnabled(1) will cause the window to be repainted and all modifications to the window that have been made since calling setRepaintEnabled(0) will appear.

Certain major structural changes to the window always force an immediate repaint.
