Maintain display list on window

Hi everyone,

I'm using the dlAttachDlistToWindow to draw on window, but I'm struggling with two things, this only render one time and if I move the mouse or pan the image disappear.
and when I draw something, the layout disappear. 

For the erase stuff the closes thing I found is dlSetClearOnDraw but don't prevent that.

For the disappearing problem, I was thinking about using loops to keep the drawing but is not the optimal solution.
is there any extra documentation about this apart from the Cadence User Interface SKILL Reference ICADVM20.1?



 


/* First, make the DisplayList. */
dl = dlMakeDisplayList( )
/* Now make a pen table for it. */
penTable = dlMakePenTable(5)
/* Assign the penTable to the display list. */
dlSetPenTable( dl penTable)
/* Define a couple of colors. */
colorIndex = hiStringToIcon( nameToColor( "blue"))
dlSetPenColor( 1 colorIndex penTable)
/* Set this pen "filled." */
dlSetPenFillStyle( 1 "SolidFill" penTable)
/* Put the objects in. */
dlAddBox( dl 1 0:0 100:100)
dlAddBox( dl 2 10:10 90:90)
dlAddCircle( dl 3 50:50 20)
dlAddStrokeText( dl 4 50:50 "Window" "0" "gothic" 20 "center")
/* Make a window. Put the DisplayList into the window */
/* and set the windows icon. */
w = hiGetCurrentWindow()
;dlSetClearOnDraw(dl w)
dlAttachDlistToWindow( dl w)
