The example of this article describes the implementation method of Java simulation QQ desktop screenshots. Share it for everyone for your reference. The specifics are as follows:
The desktop screenshot function of QQ is very convenient. Last year, I used Java to simulate one, and it is now sorted out.
This method first needs to catch the entire image of the screen, display the image in a JFRAME, and then display the full screen of JFRAME. In this way, a desktop is simulated, and Java can get the action area of the mouse to achieve the small on the desktop in the desktop Screen screenshot.
