OSX: revBrowser won't allow you to turn scrollbars back on

[David Bovill]

>From the docs:


> Cross Platform Caution: Due to a limitation in the current browser
> implementation, the behavior of the scrollbars property is slightly
> different on Windows and OS X. In particular, under OS X, when navigating to
> a page for the first time after disabling scrollbars, revBrowser won't allow
> you to turn scrollbars back on. The way to work around this and create a
> browser that allows scrollbars to be toggled on both platforms is like this:
>
> local sBrowserId
>
> on browserOpen
>   put revBrowserOpen(the windowId of me, "http://www.runrev.com") into
> sBrowserId
>   if the platform is "MacOS" then
>     send "browserDisableScrollbars" to me in 1 second
>   else
>     revBrowserSet sBrowserId, "scrollbars", false
>   end if
> end browserOpen
>
> on browserDisableScrollbars
>   revBrowserSet sBrowserId, "scrollbars", false
> end browserDisableScrollbars
>
> on browserToggleScrollbars
>   revBrowserSet sBrowserId, "scrollbars", (not(revBrowserGet(sBrowserId,
> "scrollbars")))
> end browserToggleScrollbars


I'm not quite sure what the issue here is with OSX, and am trying to create
a pair of getprop / set prop handlers that work on OSX:

getprop browser_ScrollBars
   put the browser_ID of the target into browserID
    if browserID is empty then
        -- a default if the browser is not open
        return empty
    else
        return revBrowserGet(browserID, "scrollbars")
    end if
end browser_ScrollBars

setprop browser_ScrollBars someBoolean
    put someBoolean is not false into someBoolean
    put the browser_ID of the target into browserID
    if browserID is empty then return "Error: no browser open for this
object"

    if the platform is "MacOS" then
-- not sure what to do here to fix OSX issue?
        -- send "browserDisableScrollbars" to me in 1 second

        -- this does not work to trun them back on?
        revBrowserSet browserID, "scrollbars", someBoolean
    else
        revBrowserSet browserID, "scrollbars", someBoolean
    end if
    return the result
end browser_ScrollBars

Is the issue one that I need to send a message on OSX rather than issue it
direct?
