[Closed] Change rollout color dynamically

As it looks to me the bgcolor property of a dialog can only be set on creation.
however, you can use a bitmap for the bgcolor and then use the ‘SetDialogBitmap’ method to change the color, like in this example:

rollout testRollout "rollout"
(
-- Local Variable Declerations
------------------------------------------
	
	local w = 200
	local h = 50
	local bgMap = bitmap w h color:white

-- User Interface
------------------------------------------
	
	colorPicker cpBG "BG Color:"

-- Functions
------------------------------------------
	
	fn changeBGColor col =
	(
		bgMap = bitmap w h color:col
		SetDialogBitmap testRollout bgMap
	)
	
	fn openDialog =
	(
		createDialog testRollout width:w height:h bitmap:bgMap
	)

-- Event Handlers
------------------------------------------
	
	on cpBG changed col do changeBGColor col

) -- end of rollout

testRollout.openDialog()

And it immediately shows that the bitmap is not gamma corrected and the color picker is! When you use gamma settings of course.

That really really needs to be fixed ASAP.

It’s retarded that all of my buttons etc are wackobizzaro gamma-ed.

as annoying as that is, surely a very swift getPixels -> apply gamma -> setPixels will take care of that?

Zeboxx you’re right and in this instance you can even replace the changeBGColor fn

	fn changeBGColor col =
	(
		bgMap = bitmap w h color:col gamma:(IDisplayGamma.gamma)
		SetDialogBitmap testRollout bgMap
	)

Thanks TZMtn. Thats is a good work around. Too bad you can’t change the position. Oh well. I could try using a normal bitmap to.

Can’t change what position?

The position of the bitmap using SetDialogBitmap. I have a toolbar in the window. It looks a bit weird having different colours undeneith the buttons.

Well you could setpixels per row for only the upper rows… and change the colors to something more appropriate.
