My definition follows a more "windows" slighted definition. When one uses the file explorer the right border of the folder listed tree control is a splitter it splits and allows resizeing of the folder listing.
There's no pre-made control that does this but they are trivial to write. You can either place a narrow button where you want the splitter to go, or you can just track the mouse position without using a control. When the mouse goes down, get the rect of the field on the left and the field on the right. Set the right edge of the left-hand field to the mouseH and the left edge of the right-hand field to the same mouseH. That's it.
For example (this assumes a narrow, transparent button between the fields):
-- note: untested, but should basically work
on mouseDown -- script of the narrow button doSplitter end mouseDown
on mouseUp stopSplitter end mouseUp
on mouseRelease stopSplitter end mouseRelease
on doSplitter put item 1 of the loc of me into theH get the rect of fld theLeftFld put theH into item 3 of it set the rect of fld theLeftFld to it get the rect of fld theRightFld put theH into item 1 of it set the rect of fld theRightFld to it set the loc of me to it,item 2 of the loc of me send "doSplitter" to me in 100 milliseconds -- adjust as needed end doSplitter
on stopSplitter repeat for each line L in the pendingMessages if L contains "doSplitter" then cancel (item 2 of L) end repeat end stopSplitter
If you don't want to use the transparent button, then just check the x position of the mouse on mouseMove and calculate whether you should start the splitter or not. (That's usually how I do it, it avoids an extra control.)
