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())
