BBjAppletProxy::setBounds

Description

In BBj 2.02 and higher, this method sets the location and size of a running Applet.

Syntax

ReturnValue	Method
void	setBounds(int x, int y, int width, int height)

Parameters

Variable	Description
x	Specifies the horizontal position of the upper-left corner of the control in current units.
y	Specifies the title of the menu.
width	Specifies the width of the control in current units.
height	Specifies the height of the control in current units.

Return Value

None.

Remarks

Applet is always constrained by the height and width parameters given in the HTML from which the Applet was launched. The setBounds method can only move and resize the Applet within those original parameters.
