Fullscreen without taskbar with java
1
i am working on a java application that will serve as a lock screen for my Windows PC. I designed the lock screen to display using swing, when i run the app i works but the task bar is still visible under the app which is not what i want because it can be used to overwrite my app.
I have tried
private Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
setDefaultCloseOperation(javax.swing.WindowConstants.DO_NOTHING_ON_CLOSE);
setAlwaysOnTop(true);
setUndecorated(true);
setSize(screenSize.width, screenSize.height);
but it didn't work, so i tried the answer provided for this question, it still did not work.
Any suggestions on how to make the app display in full screen mode and completely hide the task bar?
Below is a Sublime Text screenshot of what i mean.
I am running JDK1.8 on windows 8.0

setSize(screenSize.width, screenSize.height);

so it tried the answer...- works for me. The key is the undecorated frame. If it is not undecorated then you can use the mouse to drag the frame which defeats the purpose. I'm using JDK1.8 on Windows 7.

LoL at the mistake. Thank you for pointing it out.

My form is undecorated. I will edit now and add that part.

As I stated it works fine in my environment. Tell us your environment and post code that can be copied/compiled and tested. Maybe others who use your environment will test and report the results.

Why did you post all that code? Your requirement is to display the frame over the entire screen. You don't need any components on the frame to test out the basic concept. First get the code working without components. The whole test class will be about 10 lines of code. Once you get that working, then you start playing with the rest of your application and add components. When problem solving you need to simplify the problem if you want us to read the code and test the code.

so it tried the answer...- works for me. The key is the undecorated frame. If it is not undecorated then you can use the mouse to drag the frame which defeats the purpose. I'm using JDK1.8 on Windows 7.

As I stated it works fine in my environment. Tell us your environment and post code that can be copied/compiled and tested. Maybe others who use your environment will test and report the results.

Nov 20 '18 at 16:52
Why did you post all that code? Your requirement is to display the frame over the entire screen. You don't need any components on the frame to test out the basic concept. First get the code working without components. The whole test class will be about 10 lines of code. Once you get that working, then you start playing with the rest of your application and add components. When problem solving you need to simplify the problem if you want us to read the code and test the code.

pack();
Why are you using the pack() method?
It will cause the frame to be displayed at its preferred size, which is based on the preferred size of the components added to the frame.
The pack() method will override the size set in the setSize(...) statement since it is executed AFTER the setSize(...) statement.
