Example : <copy and paste script below to CE Table and execute>

Code:
f = createForm()
f.width, f.height = 300,250
pnl = createPanel(f)
pnl.left,pnl.top = 10,10
pnl.width,pnl.height = 280,180
pnl.Caption = 'Panel for mouse pos action'

lblX = createLabel(f)
lblX.left, lblX.top = 10, pnl.top+pnl.height + 20
lblX.font.size = 14

lblY = createLabel(f)
lblY.left, lblY.top = lblX.left + lblX.width + 150, pnl.top+pnl.height + 20
lblY.font.size = 14

function pnlOnEnter()
 z=createTimer(nil)
 z.Interval=100
 z.OnTimer=function(z)
 local x,y = getMousePos()
 x,y = pnl.ScreenToClient(x,y)
 lblX.caption = 'X.pos : '..tostring(x)
 lblY.caption = 'Y.pos : '..tostring(y)
 return x > 0 and x < pnl.width and y > 0 and y < pnl.height
 end
  z.Enabled=true
 end

function pnlOnLeave()
 z.destroy()
 x,y = 0,0
 lblX.caption = 'X.pos : '..tostring(x)
 lblY.caption = 'Y.pos : '..tostring(y)
end

pnl.onMouseEnter = pnlOnEnter
pnl.onMouseLeave = pnlOnLeave

Thats mean "set the x value must be greater than 0 and less than panel width and set the y value must be grater than 0 and less than panel height"

oh ok, but I don't think it helps in this code, since it returns to pnlonenter, and you can hold left mouse down when your on panel and drag it.
anyways, thx for help!! Cool

If you fully understand the 'return'' statement, then you will know, how that return command on that function is needed.

"A return statement returns occasional results from a function or simply finishes a function. There is an implicit return at the end of any function.

So you do not need to use one if your function ends naturally, without returning any value.
