Hello Everyone,

im building a E4 Application with e(fx)clipse. I tried to create a Addon for my Trimmed Window like this :

package de.demo.app.handlers;

import javax.annotation.PostConstruct;

import org.eclipse.e4.ui.model.application.MApplication;
import org.eclipse.e4.ui.model.application.ui.basic.MTrimmedWindow;

public class InitWindowAddon {

	@PostConstruct
	void init(MApplication application) {
		/*
		 * Preconditions.checkArgument(application != null,
		 * "Application dont exist!");
		 * 
		 * Preconditions.checkArgument(!application.getChildren().isEmpty(),
		 * "Application has no Children!");
		 */

		if (application.getChildren().get(0) instanceof MTrimmedWindow) {

			MTrimmedWindow window = (MTrimmedWindow) application.getChildren()
					.get(0);

			window.setLabel("Es ist perfekt!!!");
		}
	}
}


I also tried to used Guava Librairies without success. But after a while when i run my product i see those Errors :


Quote:

!STACK 0

I has already such Errors in the past, and i removed from my run configurations all SWT Plugins. But this Errors suddenly come again.

Why and How can i solve this?

So where do you see this message, when you launch your app? This makes
no sense at all. You noted the term "ide" in the package name? To me it
looks like you are not launching the e4 app but an inner IDE.

So are you writing an SWT e4 app which embeds JavaFX or a pure e4 JavaFX
application? If it is the latter please make sure that you've set an
appropriate target platform (this would make your first problem
disappear as well).

In case you want to embed JavaFX into e4 you need to make sure that the
rendering engine of SWT is used.

Hallo Tom,

i just want to use a pure e4 JavaFX. I follow your tipps and tried to set a new Target Platform for my Project like this : wiki.eclipse.org/Efxclipse/Tutorials/Tutorial4.
Im using Eclipse Kepler and after set the Target Platform i see an Error saying that Quote:
You have selected a target with a newer version than your current Eclipse Installation. This can cause unexpected behaviour in PDE. Please use a newer version of eclipse.


And when im running the product.launch : Quote:
"org.eclipse.fx.ui.workbench.fx" was unable to instantiate class "org.eclipse.fx.ui.workbench.fx.E4Application".


By the way my Project is build like i already wrote on Google Groups : groups.google.com/forum/#!topic/efxclipse/olNlqcbkhe8.

Thanks

That's not a problem!

Not sure what's wrong with your launch config. Does the project itself
compile?

Hi Tom,

Yes the Project itself compile (mvn clean install). But when i run it (right click -> run as.. ), it dont show my application anymore and show this error message. Thats happend since i touched the Target Platform in Eclipse Preferences.

Here the Whole Error :

Well! My Bad!

I forgot after changing the Platform to go into my product :

1. Into my Product Overview -> Product Definition Tab -> set Product and set Application

After that i opened the Run Configuration -> Plugins -> press Add required Plugins.

Now my Application run without any Errors. I hope i have now the right settings.

Thanks to Tom.
