Jacob, I followed your advice by posing at the apple discussions
forum – Here is a link to the post:
http://discussions.info.apple.com/thread.jspa?messageID=11438654
Basically, from there they sent me here:
http://stackoverflow.com/questions/1981453/getting-the-main-window-of-an-app-via-an-nsrunningapplication-instance
Saying it is difficult, if not impossible to get the main window
of other apps unless they participate in inter-Application Communication –
I don’t have any guarantees that that will be the case; but, there seems
to be at least one person who has posted here that thinks this IS
possible. Unfortunately, I don’t have any Objective-C experience by
which I can begin implementing a solution, and it seems that when I do find a
particular Objective-C hint or clue, I have no way of using it in eclipse’s
SWT. Case in point: I have no idea how to access CGWindow.h’s
methods/variables in SWT – I can create an NSWindow, but then comes the
problem of initializing it with my application.
So I’m back to the original issue, and whether or not it
is actually possible. Unless there is a different approach or hack that
someone knows about.

Subject: Re: [platform-swt-dev] Window Position - Mac
I think this is looking more like a question for a Mac
specific channel. I suggest posting in Apple's forum: http://discussions.apple.com/index.jspa
. When you've got a solution to your problem in Objective-C/C we can help you
integrate/port it to Java and SWT.

Do you have an example of how to access the window information
with the current process? The bare minimum that would get me by would be
to find it’s x,y screen coordinates… anything else beyond that is
icing.
I think it may be what he wants
but I don't know how to get from a window number to an actual window.

If the "any application"
means the application in other process, the answer is: no. Mac do not have
global window or control handle as HWND on win32. So you can just get window
information within current process but have no idea about window in other process.
But there is other method to get
position of window in other process, you could try Accessibility API on Mac.
You may need to write c code to use it.
sendmsg
in cocoa is object-c method. It is totally different with SendMessage on win32.
I have been searching for awhile
now for a Mac equivalent of the org.eclipse.swt.internal.win32 functions
FindWindow() and GetWindowRect(). I would like to be able to launch any
application, gain control of it and query it to find out where it’s top
left position is. If there is a way to do it by setting its position,
that would also work for me.
In the
org.eclipse.swt.internal.cocoa I have seen some things about sendmsg –
but I haven’t been able to find any good examples of how that works in
swt, or if that is even what I need.
