We're making a user-space device driver for OS X that moves the cursor using Quartz Events, and we ran into a problem when games — especially ones that run in a windowed mode — can't properly capture the mouse pointer (= contain/keep it within the boundaries of their windows). For example, it would go outside the game window and click on the desktop or nearby inactive applications.
We could fix this if only we could detect when an active application calls CGAssociateMouseAndMouseCursorPosition.
How would you do this? Any ideas are appreciated.
I dont know if this can help you
There is an option called Focus Follows Mouse
Focus Follows Mouse - The Mouse pointer will grab automatically change focus to a new window inisde this one app if you mouse over it, instead of having to click a window to get focus, then clicking to do something.

I have written a few different mouse logical layers (for bridging different input devices, etc.). I have found that hooking into the OS level WM_INPUT event is a sure way of getting very real-time mouse position information. There is also a less rigorous solution of just polling the mouse data you need from one of Windows' very primitive DLLs. They are lightning fast. You could poll on a 10ms timer and never see performance loss on a modern machine.
I've been searching for a mouse broadcaster for Mac for a while and it seems there are no solutions for doing this, so I must look for alternative solutions now. I'm wondering if AppleScript is capable of performing such a task. Basically, what I would like to do is read mouse position and action when performed in one application for as long as the script is active, and broadcast/replicate it in one or more other applications. Is AppleScript capable of this?
Just to clarify, I'd need to simulate mouse movement in the other applications... for example, if I opened up several instances of a drawing program, assuming that the program had the same resolution, anything I drew in the main program, would replicate on the other programs.
Really applescript cannot do what you need. It's not made for that. Applescript is made to run the commands in an application's applescript dictionary. I assume that the dictionary of the applications you want to control give you no way to read and control the mouse.
You do have an applescript alternative though. I have made a command line tool to read the mouse position and also to move the mouse. So theoretically you can do what you want with applescript and my tool. I do not believe you will get the results you expect though. Anyway you can try. Here's a link to the web page for my tool. I hope it helps.
Get it here.
Your basic approach could be 1) activate the application you want to read the mouse position, 2) run my tool in a repeat loop and record the mouse positions, 3) activate the second application that you want to duplicate the mouse movements, 4) use a repeat loop with my tool to make the mouse move according to how you recorded it.
Is it possible to create an invisible X window? For initialization of an OpenGL ES 2.0 context, one has to create a X window manually, but I can't find a way to make it invisible. Since I'm only doing GPGPU I don't need an output window. In fact, it is rather annoying in my case.
I'm aware of a solution from an earlier question, where it has been pointed out to use InputOnly in XCreateWindow(). This, however, leads to the X error GLXBadDrawable. Probably because EGL requires the window to respond to graphics request. Is there another way? Maybe create it minimized? But I can't find anything on that either. Also setting the window's size really small doesn't help, since it always occupies the whole screen on my device (Nokia N9).
When you create an X window, it is created unmapped, so what about creating an InputOutput window and leaving it unmapped? Another option would be (if the window must stay mapped), to move it out of the screen.
Although I have a feeling that this isn't technically possible, it's worth asking anyways. Is it possible to turn on the Macbook Pro's keyboard backlights for individual keys? I am working on a piece of grid-based software which allows the user to navigate around by pressing any key on the keyboard to position the cursor at that point in the grid. It would be very cool if I could somehow just turn on the backlight for certain keys to give the user an easy way to see the current position of the cursor.
Is it even possible for an application to control the keyboard backlighting at all, let alone for individual keys?
Yes, on programs controlling the backlight.
iTunes visualizer that pusles keyboard backlighting to music:

How to manually adjust (via plugin):
http://osxdaily.com/2006/11/30/how-to-manually-adjust-the-macbook-pro-keyboard-backlight/
Not sure on programs controlling individual keys, but as that would require additional hardware to be installed on Mac's part, i doubt it.
Well after trawling the webs, it looks like the answer to that is no. But I'd like to point out that each key does have its own key- a tiny little LED (same kind they use under phone keypad buttons). Also, I've seen some people saying that flashing these lights on and off repeatedly is bad for them. Bullshit- all digital electronics control light output from LED's by flashing on and off many many times a second. Read up on PWM on wikipedia or something..
Anyways just had to get that out there :)
Thanks,

Is there anything like Winsplit Revolution for Mac OS X?
Try these:
Zooom/2 ($15) has been my favorite since I installed it. Fast, flexible, and minimizes the number of key combinations I need to remember
Divvy ($15) might soon replace Zoom/2 for me. It's closer to Winsplit. You can arrange windows on a grid, define your own grid arrangements, and define your own shortcuts. It also minimizes the number of keystroke combinations you need to remember. BONUS: There are Mac and Windows versions, which means if you use both platforms you can use the same window management method across all your machines.
Breeze ($8) makes it easy to make windows fullscreen, split left, or split right. It also lets you save screen states (generic) and for specific apps.
Moom ($5) is a more recent entry. It supports both keyboard shortcuts and mouse shortcuts. For the mouse shortcuts, moving the cursor over the greeen zoom button displays a popup list of different layout options: full screen, left/right half, top/bottom half, or any of the corners.
SizeUp ($10) mimics various aspects of WinSplit functionality, but it relies on many keystroke combinations that take time to learn. The advantage is quickly moving windows. The drawback is that it uses up a lot of global keyboard shortcuts, and there are so many I couldn't remember them all.
Cinch ($7) is a mouse-driven app by the makers of SizeUp. Drag your window to various hot zones on the screen edges and the window will "cinch" to that edge and resize to fill half the screen. Similar to the built-in resizing feature in Windows 7.
MercuryMover ($20) is quite powerful and offers fine-grained control. However, there are a lot of different key combinations and, overall, I didn't find it as easy to learn or as elegant as WinSplit. I uninstalled it almost immediately. It struck me as powerful, but inefficient and unwieldy.
The DIY approach (free) mentioned in another post is to combine some applescripts and bind them to quicksilver triggers. I haven't tried this. But it is a free solution.
I found the weak window management one of the hardest things to cope with when I started using a Mac.
Why go beyond spaces and expose?
Winsplit significantly adds to what spaces and expose can do. I didn't understand the appeal until I actually used it. Before that, I thought virtual desktops (ie, like spaces) was enough. Now I consider it must-have functionality, especially on large monitors and multi-mon setups.
On my Windows machine running 3 monitors, I would rank the importance of these different apps in the following order:
Winsplit-like window rearranging
Spaces-like virtual desktops
Expose-like application switching
On my MacBook, I've learned to approach it the other way.
Expose-like application switching
Winsplit-like window rearranging
Spaces-like virtual desktops
From the Winsplit website I understand more or less the functionality; in the past I actually used to have my window manager (Waimea) configured to do exactly that in linux.
You may try using Quicksilver to trigger one of a custom set of applescripts; each applescript would resize and move the currently focused window to a predefined location.
See this macosxhints post for inspiration...
ShiftIt is a free option. Assignable hotkeys to resize to different portions of the screen (Left, Right, Top, Bottom, Top Left, Top Right, Bottom Left, Bottom Right, Full Screen and Center with current size)
Link to ShiftIt on github
Just click on the big download button towards the right of the screen.
Spectacle is a good option, its free and open source. And easy to use with keyboard shortcut :
Windows can be moved to a number of predefined regions of the screen:
Move to the left half ⌥⌘←
Move to the right half ⌥⌘→
Move to the top half ⌥⌘↑
Move to the bottom half ⌥⌘↓
Move to the upper left ⌃⌘←
Move to the lower left ⌃⇧⌘←
Move to the upper right ⌃⌘→
Move to the lower right — ⌃⇧⌘→
Another question on StackOverflow adresses the same issue
https://stackoverflow.com/questions/276760/tiling-window-manager-for-os-x
One answer provided links to an app called TwoUP. It's free, and does the job on OSX!
Thanks to Dong Hoon's answer, I have developed a hybrid solution. Using the AppleScript Editor, you can create scripts to resize the current window, like this:
tell application "System Events"
set _everyProcess to every process
repeat with n from 1 to count of _everyProcess
set _frontMost to frontmost of item n of _everyProcess
if _frontMost is true then set _frontMostApp to process n
end repeat
set _windowOne to window 1 of _frontMostApp
set position of _windowOne to {5, 0}
set size of _windowOne to {1150, 735}
end tell
such a script will work on a 13" MacBook. Using subtle variations of this script saved to /Users/[YourUserNameHere]/Library/Scripts, you can have configure the AppleScript Editor to show itself in the menu bar, where it will allow you to select a script to run.
Using several different scripts, I'm able to resize and reposition any window with only two clicks.
Hope this helps.
It looks like TwoUp is dead, but here are some other options:
Cinch ($7) is like Aero Snap for Mac.
Breeze ($8) allows you to save window states and restore them like a template to another window.
Divvy ($14) shows a grid on the screen where you can select boxes to indicate how you want the window to fill your screen.
I haven't used Winsplit, so I don't know how it compares, but an app I developed, Optimal Layout, offers very flexible window tiling, as well as moving and resizing from the keyboard:
http://most-advantageous.com/optimal-layout/
You can also try Arrange application which features resize and reposition with keyboard shortcuts, on screen menu and by dragging window.
You should also try out secondbar. gives you an extra menubar at the second display + re-arrange options. See this link.
You can even try SplitScreenapp.com. It allows you to resize Mac Windows in many ways including full split, half split, drag and snap, etc.
I doubt it. Between Spaces and Expose, there's not much need for a third-party app to help manage multiple windows.
