[Closed] Floter's height depends on rollouts ?

fn resizeRolloutFloater theRollout =
 (
 	local theHeight = 0
 	for i in theRollout.rollouts do 
 		if i.open then theHeight += i.height else theHeight += 21
 	local theMaxHeight = sysinfo.desktopSize.y - theRollout.pos.y - 32
 	if theHeight > theMaxHeight do theHeight = theMaxHeight 
 	theRollout.size = [theRollout.size.x, theHeight]
 )
 
 --for example (I tested with the Krakatoa floater, replace with your own rollout)
  resizeRolloutFloater Krakatoa_Gui_floater 

The function gets all rollouts from the floater and adds their height together to a user variable. If the rollout is closed, it adds 21 (the height of the title bar), otherwise it adds the actual height.
Then it compares the accumulated height with the actual desktop height minus the vertical position of the upper left corner of the floater and if the floater would be higher than this size, it caps it there (remove it to allow the floater to grow infinitely regardless of screen resolution).
Finally, it assigns the old width and the new height to the size property of the floater and thus resizes it.

Awesome

But now, when do you call the function ?

how would I call this function as soon as the user changes the “opening” of a rollout ? :deal:

you know, something like

On RolloutOpening changed do
(
resizerollout
)

is there anything like this or will I have to use like callbacks wich I really don’t know how to use

Well thanks a lot maXster :love:

Declare the floater variable as global.
Define the function in a higher scope than the rollouts.
Put the call in each on open handler in each rollout.

THANKS A LOT

This is great really
