@DISPLAY vs CreateDisplay arguments

[amyren]

Is there any reason why @DISPLAY does not accept variables for arguments, while CreateDisplay does?

I made an example to show what works.

Code: Select all

mywidth = 600
myheight = 400
mycol = "$959595"
CreateBGPic(1, mywidth-400, myheight-300, #WHITE)
@DISPLAY {width = 800, height = 600, color = #GREEN}
CreateDisplay(2, { Width = mywidth, Height = myheight, color = mycol})
OpenDisplay(2)
CreateDisplay(3, { bgpic = 1})
OpenDisplay(3)
Wait(100)

This will not work, since @DISPLAY does not seem to take any arguments.

Code: Select all

@DISPLAY { Width = mywidth, Height = myheight, color = mycol})

Also, @DISPLAY does not accept the argument bgpic = 1

@DISPLAY is a preprocessor command, which are processed before the rest of the script, so your variables mywidth, myheight and mycol don't exist yet.

Thank you, that explains it. I was not aware of that preprocessor also ment that it would be processed before any code written above.
