BBjAppletProxy

Description

The BBjAppletProxy provides control of the Applet and AppletContext when a BBj program is being run through an Applet.

Creation

BBjAPI > BBjAppletProxy

The BBjAppletProxy object is created through the following BBjAPI object method:

Return Value	Method
BBjAppletProxy	getAppletProxy()

Methods of BBjAppletProxy

Return Value	Method
void	setBounds(int x, int y, int width, int height)
string	getParam(string paramName)
void	showDocument(string URLName, string frameName)
void	showStatus(string statusMessage)
void	playAudio(string URLName)
void	playAudio(string URLName, string relativeName)
void	addFrame(int x, int y, int width, int height, string URLName, string frameName)
void	removeFrame(string frameName)

Remarks

A BBj program cannot obtain an Applet Proxy if the program is not being run from within an Applet environment (BBjAPI().getAppletProxy will fail).

Constants

None.
