Re: Moving vertical scrollbars from Right to Left Side of Windows

Thanks for insulting me. :)

I'm young, but I am not by any means new to software development. My
argument was not that changes to the API would require recompilation to take
advantage of the features. I know what version changes are like.

However, when you create a multiline textbox, or (an even simpler example)
when you create an HTML application or web page that uses IE as the
container, you simply request the presence of a scroll bar. You are not
responsible for creating that scroll bar nor does your application need to
know anything about the location of the scroll bar. That's the operating
system's job of drawing.

Someone mentioned PointToClient and ClientToScreen needing to be changed. Of
course they'd need to be changed, but that's part of the OS implementing it.
My argument was not that it wouldn't require changes to several API's,
rather that these changes should be able to be transparent to existing
applications. That's the whole reason PointToClient and ClientToScreen were
created, because you aren't supposed to know what's outside of your client
area or how your client area relates to the screen -- that's the OS's job.

So let me play devil's advocate here. Let's say I am wrong about the Win32
API (not saying I am or am not wrong, just have not yet heard anything that
makes me think it's not possible to do transparently). Why can't Internet
Explorer easily have a left hand scroll bar option? Web pages are not
dependent on the scroll bar being on the right.

Granted, you won't be able to catch custom scroll bar implementations
(flash, java, etc) but your OS-supplied scroll bars (such as on listboxes,
multiline text boxes) and your browser-supplied scroll bars (scrollable
DIV's, BODY, frames, etc) should be able to be relocated with minimal
application changes.

I can see I'm outnumbered here so I'll stop wasting space on Microsoft's
servers. I just still don't see what requires a recompilation.
