Looking for short script for Viewer Pane hor/ver layout

Hello,

I was away from dopus for a long time and it would take me a while to figure out the whole scripting stuff myself hence I'm asking for a ready solution.

if lister height > lister width then open Viewer Pane in vertical layout (Viewer under lister)
else horizontal layout (viewer to the right)

I will replace default F7 shortcut with it.

Thanks in advance for any help !!

Option Explicit
Function OnClick(ByRef clickData)

	Dim lister
	Set lister = clickData.func.sourcetab.lister

	if lister.viewpane > 0 then
		clickData.func.command.RunCommand "Set VIEWPANE=off"
	else

		Dim w, h
		w = lister.right - lister.left
		h = lister.bottom - lister.top

		if w > h then
			clickData.func.command.RunCommand "Set VIEWPANE=vert"
		else
			clickData.func.command.RunCommand "Set VIEWPANE=horiz"
		end if
	end if

End Function

Thank You - that did the trick.
