Why doesn't setPos() work to position a dialog box?

If setPos worked, the following code should put a dialog box at the top left of the screen, but it doesn't do that and placement doesn't seem to be related to the coordinates in the setPos() call. Anyone know why?

DB dB=topMost "hello world"
setPos(dB,0,0)
label(dB,"Why?")
show dB

Actually, I did get it to work once when run after freshly starting DOORS. But then subsequent invocations kept moving the origin lower and right. Kind of defeats the purpose of the function!

Interesting.
 

DB dB=topMost "hello world"
label(dB,"Why?")
realize(dB)
set(dB,0,0)
show dB

As you said, this works for me the first time I run it after I log into DOORS. But after I close the dialog box and run it again, it does not work as it should. However if you use numbers other than 0 for both it seems to work all the time. And yes if you use realize(DB, int, int) that seems to work all the time as well.

Yes, you can set the original position with the realize(DB, x, y) command. Yes, you can dynamically change the position after its realized with the setPos(DB, x, y) command. This may come up in a callback or button. The following demonstrates it.

DB dB
 
void applyMoveIt(DB dbXX)
{
   int x = 0, y = 0
   getPos(dB, x, y)
   if (x == 10)
        setPos(dB, 200, 10)
   else setPos(dB, 10, 200)
}  // end applyMoveIt()
 
 
dB=topMost "hello world"
label(dB,"Why doubt me?")
apply(dB, "MoveIt", applyMoveIt)
realize(dB, 200, 200)
show dB

DB dB

{
   int x = 0, y = 0
   getPos(dB, x, y)
   if (x == 10)
        setPos(dB, 200, 10)
   else setPos(dB, 10, 200)
}  // end applyMoveIt()
 
 
dB=topMost "hello world"
label(dB,"Why doubt me?")
apply(dB, "MoveIt", applyMoveIt)
realize(dB, 200, 200)
show dB

Thanks Louie, I never knew that.
I wonder what use that could be?

Try this

DB db = null 
DBE dbeTimer = null
 
void doClock(DBE dbe) 
{ 
    setPos(db, random(900), random(600))
} 
 
 
db = create(dbExplorer, "Catch", styleCentered) 
 
label(db, "Catch me if you can!")
 
dbeTimer = timer(db, 1, doClock, "") 
 
realize db 
 
setCenteredSize(db, 200, 100) 
 
show db
