Dears,
I have been developing a project which use web cam as source of input to imitate as mouse event on mac. I'm always handle with opencv for image processing and Qt framework for GUI framework.
My problem is, I want to write a program which imitates mouse. I don't know how to control a mouse out of the window form and sent the interrupt to the operating system. Is there any simple code? or could any one give me some hint?
Any comments will be appreciated. Thanks in advance, nofortee
For modern Operating Systems, a mouse is a fundamental input device. As such it's handled by a driver in the OS. There the mouse is tied closely to the pointer. For programmers like you, it's important to get the distinction between mouse and pointer right. It sounds like you actually want to control the pointer, not the mouse.
One option is to use X11's XTEST extension and other Xlib functions.
To enable this on a mac read the answer from this question: http://stackoverflow.com/questions/1264210/does-mac-x11-have-the-xtest-extension
defaults write org.x.X11 enable_test_extensions -boolean true
Here is a tool already built using this technology: http://www.semicomplete.com/projects/xdotool/
UPDATE: Another option could be to use the built-in Automator tool.
