Display a Red frame on the screen
Hello I have two monitors attached to the computer, and when i click in System Preferences/Displays Preferences on the display image (Display arrangement tab), the screen of the clicked scematic monitor's image monitor is being surrounded by a red frame. How could i do something like this from my application? I don't need the red frame around the whole screen, but i would like to have some area on the screen. Is it possible to do using some kind of API? Thanks! ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

You probably want a borderless window (which is a flag you can pass when you create the window) so that the window doesn't have content by default. -- David Duncan ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Display a Red frame on the screen
Hi David, thanks for the answer I was thinking about the window. But then it has to be something with a big hole inside. This hole ought to be transparent for mouse clicks (so if there's something below my window, that 'something' has to be clickable and focused, and receive keyboard input)? Is it possible to do somehow? Borderless is a window without a title (as i understand). What kind of properties should i specify to make a window as that Red frame? I mean, i really want it to be just a mark for the user, without any windowing behaviour (well, the user can drag it, if he clicks on the 'red frame' with mouse, but that is the only relation to a real window it should have). In OS Windows i would probably use Regions API, but i have no idea what to do in Mac OS. Could you give me a clue? thanks 2011/4/8 David Duncan david.dun...@apple.com: You can use NSScreen to get a list of available screens and then just create an NSWindow on whatever screens you want.

See this little project. It uses a (borderless) window to place a 'puff* graphic under the mouse cursor. http://www.harmless.de/cocoa-code.php#floatingimage Andreas___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
