BBjMenuButton::setDisableOnClick

Description

In BBj 16.0 and higher, this method sets a boolean value indicating whether this BBjMenuButton should be immediately disabled when the user clicks it.

Syntax

Return Value	Method
void	setDisableOnClick(boolean disable)

Parameters

Variable

Description

disable

Specifies whether this button should be immediately disabled when the user clicks it.

0 = Don't disable on click (default).

1 = Disable this button when the user clicks it.

Return Value

None.

Remarks

When clicking a button triggers a long-running action, the application might want to ensure that only a single click is processed. This can be an issue in high-latency environments when the user clicks the button multiple times before the application has had a chance to start processing the resulting action.
