    Default Draw outside JFrame

    I need to be able to make a line right on my computer screen without using a JFrame. I am using Java.awt.Robot's getPixelColor, and would like to draw a "crosshair" on the screen to tell me what pixel is being tested. Therefore, I need to draw a line on the screen without JFrame. If you have a different solution to the problem, feel free to share. I'm not set on the crosshair idea. If you have a different way I can see what pixel is being tested, that would also work. I just need the crosshair to set up my program for the correct coordinates to test, because I don't know yet where the pixel is that I am testing. So if you have a way to get the coordinates of a pixel I click on, that would work too.

    Default Re: Draw outside JFrame

    If I were the one creating an application similar to this, I don't think that I'd use Java to do it, but rather a language that could allow closer interaction with the operating system such as C or C++. Your mileage may vary.

    If you've updated to Java 7 (or at least 6u10), you could try using a transparent window: How to Create Translucent and Shaped Windows (The Java™ Tutorials > Creating a GUI With JFC/Swing > Using Other Swing Features)
