Writing Eclipse plugin to modify Editor Preferences
(3 answers)
Closed 8 years ago.
I am working on a Eclipse plugin and I want to change some settings for the user in able to be able to use the plugin correctly
I need to make some changes in the settings of Eclipse using the code instead
For example:
If I want to access Window-Open perspective-Debug
Instead of telling the user these steps, I want to make it in the code
Any help ?
You have to be more specific, otherwise you're only going to end up at http://www.eclipse.org/eclipse/platform-core/documents/user_settings/faq.html . Your example is a bad one since you shouldn't be changing the perspective without the user's consent. Even then, that's not a Preference, that's an API call: http://help.eclipse.org/juno/topic/org.eclipse.platform.doc.isv/reference/api/org/eclipse/ui/IWorkbenchWindow.html#openPage(java.lang.String, org.eclipse.core.runtime.IAdaptable) .
Your plug-in should not require the user to be in any specific perspective. They should be free to arrange the editor and views any way they like.

How to get a list of current open windows/process with Java?

Closed 6 years ago.
I am currently writing a Java Application, that needs to filter the name of the Program whichs UI is front. Sorry for my bad english.
So let's say the Java App is running in Background and I open Windows -> Games -> Minesweeper then i want the App to only tell me "Active: Minesweeper". Without any additional information. Just the name "Minesweeper"
I already tried using JavaNativeAccess but I'm still unfamiliar with it.
Thanks you all in advance

How to use Java to move Windows windows around on screen?
(1 answer)
Closed 6 years ago.
I am wondering is it possible somehow to move another window on the screen to different location using Java ?
Example: I would like to move this window to the marked location.
Interfering with other programs is usually only allowed with superuser access (root). If you do not mind executing your program as root, there are possibilities, but they are certainly not cross-platform, so you would have to write a version for every OS around. I would not use java for such things.
Also, the answer about using the Windows API will not work, since you will not be able to get the window handle of a different process. Just check the documentation:
SetWindowPos Changes the size, position, and Z order of a child,
pop-up, or top-level window.
Java APIs will not help you out here.

Is it possible to run C source code from Java?

I want to make a Java app that uses the Razer Chroma SDK, but the Chroma SDK is in c++
Is there a way I can run c++ code from Java?
I must use Java for what I want to make.
I have almost no experience in c++, but I understand enough to get doing what I need.
EDIT:
This question is slightly different then others, because it is about a specific SDK, not about general c++ libraries. For this library I was able to use a simpler approach then learning to use things like JNI
You probably want to look into using JNI
The easiest way I found, and then one that doesn't require learning stuff like JNI:
Create a console application with commands that fire off what you need
In Java, launch the console application and redirect it's input and output streams so you can send it commands, and log it's output (see 12013910)
Have a command in the console application that you can pass a PID, and have the console application watch for when it closes, and then it will close itself. (This fixes having the console application not being closed if the Java application crashes and doesn't call the closing method(s))

How to detect if a graphical interface is supported?

Update: as marked duplicate, I just want to mention, this seems like a duplicate, but the answer to the other mentioned question is not completely correct. Instead refer to the accepted answer below.
isHeadless would return unexpected true in certain cases.
Its a bit weird situation, but recently I build a very simple java application which can be run in console/terminal mode or in JavaFX UI mode.
However, then while using it on a remote computer which doesn't have any display attached. I got an error that this JavaFX UI application can't be initiated on systems without display, which is pretty obvious.
To overcome this problem, I have been looking for a robust way of detecting if the system has any display attached and it can initiate a JavaFX application, which has to be a platform independent solution, since it could be Windows or Ubuntu/Linux or Mac system.
Structure of the application:
A Main console app, which depending on input arguments executes internally a console app or UI app.
So that, if any arguments given, run in console mode or if no arguments then run in UI mode.
This is where I want to detect if there is a display available from within my main console app, which then won't even try to run the UI app if display is missing.
Any idea how can we achieve this or suggestion in a proper direction would be great.
I think you could use java.awt.GraphicsEnvironment
GraphicsEnvironment.getLocalGraphicsEnvironment().getScreenDevices();
which will return an array with all the available screens. If this array is empty, there is no monitor.
Edit: About using isHeadless(), you can look at How to determine if GraphicsEnvironment exists
