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.

Example

REM Demo program for controlling BBjApplet through AppletProxy

REM Obtain the instance of the BBjAPI object
LET myAPI!=BBjAPI()

REM Open the SysGui device
SYSGUI=UNT
OPEN (SYSGUI) "X0"

REM Obtain the instance of the BBjSysGui object
LET mySysGui!=myAPI!.getSysGui()

REM Set addWindow param values
X=0
Y=0
WIDTH=960
HEIGHT=100
TITLE$="BBj Window"

REM Set the current context
mySysGui!.setContext(0)

REM Create a window
myWindow! = mySysGui!.addWindow(X,Y,WIDTH,HEIGHT,TITLE$)

REM Add buttons to the window
changeSize! = myWindow!.addButton(101,20,20,100,20,"be Large",$0800$)
innerFrame! = myWindow!.addButton(102,140,20,140,20,"show Internal Frame",$0800$)
outerFrame! = myWindow!.addButton(103,300,20,140,20,"show External Frame",$0800$)
text! = myWindow!.addStaticText(104,460,10,189,10,"select item to display on status bar")
listBox! = myWindow!.addListBox(105,460,25,160,50,"",$0000$)
listBox!.addItem("Program Name")
listBox!.addItem("Config file")
listBox!.addItem("AppServerPort")

REM set their colors and text
green! = mySysGui!.makeColor(mySysGui!.GREEN)
blue! = mySysGui!.makeColor(mySysGui!.LTGRAY)
magenta! = mySysGui!.makeColor(mySysGui!.MAGENTA)
changeSize!.setBackColor(green!)
innerFrame!.setBackColor(blue!)
outerFrame!.setBackColor(magenta!)

REM get AppletProxy and use it to set bounds of Applet
applet! = BBjApi().getAppletProxy()
applet!.setBounds(200,200,140,100)

REM define some boolean values
isLarge = 0
showingInnerFrame = 0
showingGoogle = 0

REM Register the CALLBACK routines
CALLBACK(ON_BUTTON_PUSH,CHANGE_SIZE,mySysGui!.getContext(),changeSize!.getID())
CALLBACK(ON_BUTTON_PUSH,DO_INNER_FRAME,mySysGui!.getContext(),innerFrame!.getID())
CALLBACK(ON_BUTTON_PUSH,DO_OUTER_FRAME,mySysGui!.getContext(),outerFrame!.getID())
CALLBACK(ON_LIST_CLICK,DO_LIST_BOX,mySysGui!.getContext(),listBox!.getID())
CALLBACK(ON_LIST_DOUBLE_CLICK,DO_LIST_BOX,mySysGui!.getContext(),listBox!.getID())
CALLBACK(ON_CLOSE,APP_CLOSE,mySysGui!.getContext())
