fullscreen

I am using the following code for taking a screenshot: Robot robot = new Robot(); BufferedImage image = robot.createScreenCapture(screenRectangle); ImageIO.write(image,"png", file); This code is running good. It takes screen shots of my desktop when I run the program, etc. However, when I try to run first some game, application in full screen , it doesn't work properly. It renders either black screen, either the same "initial" picture. Is this problem known, and how to fix this please? Second question : Is this possible to simulate some "Print Screen" key we can have on keybord in order to

I am new to OpenGL and Qt, and I am learning both simultaneously(3 days already:). I couple of years ago I did some exmerimenting with DirectX and I clearly remember that it was possible to make a full-screen window there. By full-screen I mean really full-screen, even without the top part where you have the close fullscreen and minimize buttons. I have this program so far: #include <QApplication> int main(int argc, char** argv) { QApplication app(argc, argv); QGLWidget w; w.show(); return app.exec(); } What should I add to it to make w full-screen?

I have created a borderless application in WPF, and it works pretty good. However, when I set the WindowState to full screen, the application takes up more space than my screen resolution, so there are some pixels outside the screen in all directions! (looks like some hard coded negative margins are added to hide the default border) Any Ideas how to prevent this from happening? My xaml: <Window x:Class="MyApp.Shell" WindowStyle="None" BorderThickness="0" AllowsTransparency="True" Background="Transparent" ResizeMode="CanResizeWithGrip" WindowState="{Binding MainApplicationWindowState}" ...

I'm writing an application that is intended to be run on a dual monitor setup, with a "Display" JFrame going fullscreen on one monitor and a "Control" JFrame on the other monitor, sending instructions to the Display. I've tried two separate methods of setting the Display fullscreen; the success of each seems to depend on the OS. display.setUndecorated(true); display.setExtendedState(JFrame.MAXIMIZED_BOTH); Works in Windows, but the JFrame gets hidden under the dock/panels in OS X and Linux. My other method, utilizing GraphicsDevice.setFullScreenWindow(display); Works in all three OSes that I

I am making a simple game and so far I've been using the Blank Activity. Now I want it to cover the entire screen, Will I need to Recode the entire thing using a FullScreen Activity? I've tried looking for something online but every thing i came across had adding this bit:​ requestWindowFeature(Window.FEATURE_NO_TITLE); getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN); Which causes the app to crash as soon as it is launched on a device. SO please if anyone can show me my error. Here is a link to the logcat output as well as the game
