fullscreen

问题 I want to create a fullscreen panel that visually blocks access to everything on the screen (desktop, menu, Unity Panel, etc in Ubuntu (11.10)), but stays below other applications' opened windows. This is mainly to make the laptop child proof. I want the kid (4 years old) to have access to some selected apps ie. gcompris, childs play, tux math, etc. but not really to other apps and settings. Something like custom desktop + launcher panel without anything to break, no access to files, etc. I

问题 In Cocoa/AppKit, given a screen from [NSScreen screens] , how can I find out if there's a full-screen app running on that specific screen? I'm mostly interested in apps that use the Cocoa APIs for full-screen, but if there's a solution that also encompasses other types of full-screen apps, even better. The solution needs be able to pass Mac App Store approval. My specific use case involves a menu bar app ( NSStatusItem ) and figuring out whether or not a menubar is shown at all on [NSScreen

问题 I have seen dozens of tutorials on this, and it seems straight forward. All I want is to make my HTML5 canvas element go full-screen (as in total full-screen, taking up the whole monitor). Here's my HTML: <p><canvas id="screen" width="800" height="500" style="background: #FFFFFF; border: 5px solid black;" role="img"> Your browser does not support the canvas element. </canvas></p> <p><a href="javascript:goFullScreen();">Go Fullscreen</a></p> Here's my Javascript (in its own .js file): function

问题 Running into the following problem specifically in Safari 5.1.2 when attempting to use the javascript fullscreen api.

问题 I am designing a psychology experiment with java applets. I have to make my java applets full screen. What is the best way of doing this and how can I do this.

I googled and found that link: Dani web But in the method described in above link you have to put a JFrame inside the applet which I have no idea how to do it. Whatever I need a quick and

问题 (Testing with C++ on Qt 4.8 and Ubuntu 12.10 unity) I've got a main window which displays a QDialog. When I put the Dialog window full-screen it does not seem to always work even though it seems to be a proper window. Meaning, the window can appear full-screen, though only sometimes. Anyone got an idea? I know Qt states it might not work for all X environments, but it can't be that bad, can it? MainWindow::MainWindow(QWidget *parent) : QMainWindow(parent), ui(new Ui::MainWindow) { ui->setupUi

问题 I've integrated AVCam in my iOS app. The problem is in iPhone 4 the preview frame isn't fullscreen, it has empty side borders... How can I solve this? Thanks. 回答1: You need to use the videoGravity property of the AVCaptureVideoPreviewLayer . Take a look to the doc. You need to use: AVLayerVideoGravityResizeAspectFill Edit: Based on that the solution founded by the asker is: - (void)setSession:(AVCaptureSession *)session { ((AVPlayerLayer *)[self layer]).videoGravity =

问题 I am creating a multi-monitor full screen DXGI/D3D application. I am enumerating through the available outputs and adapters in preparation of creating their swap chains.

问题 My app correctly runs in full screen when it's started. However after minimizing and then returning to the app, the status bar pops up and pushes my views down a little. How can I keep the status bar from moving my views?
