Dialog from Handler [message #724327] Mon, 12 September 2011 02:05 Go to next message
Eclipse UserFriend
Hello,
I want to show a Dialog from a Handler, but after 
dialog.open()
I get a 
org.eclipse.e4.core.di.InjectionException: java.lang.NullPointerException
.

This is my Handler:
public class PreferenceHandler {

	@Execute
	public void execute(IEclipseContext context, IWorkbench workbench) {
			
		PreferenceDialog dialog = ContextInjectionFactory.make(PreferenceDialog.class, context);
		dialog.open();
	}
}


and this is my Dialog:
public class PreferenceDialog extends TitleAreaDialog {


	@Inject
	public PreferenceDialog(
		@Named(IServiceConstants.ACTIVE_SHELL) Shell parentShell) {
		super(parentShell);
	}

	@Override
	protected Control createDialogArea(Composite parent) {

		Composite area = (Composite) super.createDialogArea(parent);
		getShell().setText("Connection informations");
		
		return area;
	}
}


My Enviroment:
windows 7
jdk 1.6.0_27 (32 bit)
Eclipse SDK 4.1.0

i have the same problem with the E4 tutorial of Lars Vogel!

My Enviroment:
Windows 7 64 Bit
jdk 1.6.0_26 (32 bit)
Eclipse SDK 4.1.0 Build id: I20110620-1631


public class ExitDialog extends Dialog {
	@Inject
	public ExitDialog(@Named(IServiceConstants.ACTIVE_SHELL) Shell shell) {
		super(shell);
	}

	@Override
	protected Control createDialogArea(Composite parent) {
		Label label = new Label(parent, SWT.NONE);
		label.setText("Closing this application may result in data loss. Are you sure you want that");
		return parent;
	}
	
}


public class ExitHandlerWithCheck {
	@Execute
	public void execute(IEclipseContext context, IWorkbench workbench) {
		ExitDialog dialog = ContextInjectionFactory.make(ExitDialog.class, context);
		dialog.create();
		if (dialog.open() == Window.OK) {
			workbench.close();
		}
	}
}

To me this looks like a problem in the ShellActivationListener. Please
file a bugzilla if one does not already exist.

Re: Dialog from Handler [message #725273 is a reply to message #724327] Wed, 14 September 2011 08:06 Go to previous messageGo to next message

After comparing the minimal project which is generated by the E4 Application Project Wizard with the "de.vogella.e4.todo" project where the following code works fine:

public class QuitHandler {
	@Execute
	public void execute(IWorkbench workbench, IEclipseContext context,
			@Named(IServiceConstants.ACTIVE_SHELL) Shell shell)
			throws InvocationTargetException, InterruptedException {
		if (MessageDialog.openConfirm(shell, "Confirmation",
				"Do you want to exit?")) {
			workbench.close();
		}
	}
}


i found out that the NPE can fixed by adding the addons from the Wizard-Project to the Application.e4xmi:

platform:/plugin/org.eclipse.e4.core.commands/org.eclipse.e4.core.commands.CommandServiceAddon

platform:/plugin/org.eclipse.e4.ui.services/org.eclipse.e4.ui.services.ContextServiceAddon

platform:/plugin/org.eclipse.e4.ui.bindings/org.eclipse.e4.ui.bindings.BindingServiceAddon

platform:/plugin/org.eclipse.e4.ui.workbench/org.eclipse.e4.ui.internal.workbench.addons.CommandProcessingAddon

platform:/plugin/org.eclipse.e4.ui.workbench/org.eclipse.e4.ui.internal.workbench.addons.ContextProcessingAddon

platform:/plugin/org.eclipse.e4.ui.workbench.swt/org.eclipse.e4.ui.workbench.swt.util.BindingProcessingAddon


does someone knows a tutorial where i can read what E4 Addons are and how to use them?

If one creates an "e4 Application Project" with the e4 Project Wizard, the application.e4xml is correct. But if one creates a Plugin Project and later adds a "New Application Model" with the wizard, the *Addon entries are missing.

Hi,

Well technically addons are not needed. E.g. you don't need a
CommandAddon if you are NOT using commands and handlers.

I think the NPE you get if you are NOT adding the addons is a bug
because the workbench-code itself should NOT expect an addon to be there.

So while it might be the case 99% of the time that you need addons
there's not must. The "e4 Application Project"-wizard creates them
because there commands, ... are used whereas the "New Application Model"
does not because it creates a completely empty model IIRC.

It might make sense to add a checkbox to the allow the wizard to insert
the standard fragments or give you a list of commonly known addons. Can
you please file a bugzilla and cc me on it.

Please don't hijack unrelated threads! You've hijacked 2 threads and
opened a 3rd one! I already answered in "problem opening

Hello Tom
The problem got solved by adding plugins manually to exported product.
we are showing progress dialogs in non-ui code in classes.

for some code, i made below change:
I created a Shell shell
Showed a progress dialo
closed shell
code:
// PlatformUI.getWorkbench().getActiveWorkbenchWindow(); // old code
// Shell shell = win != null ? win.getShell() : null; / old code
Shell shell = new Shell();
if (showProgress) {
new ProgressMonitorDialog(shell).run(true, true, op);
} else {
op.run(null);
}
shell.close();


I do not want to create and close shell.

I do not feel that this may be good idea, to do it at every place in code.
So can we get E4 display/shell in non-UI code or just use Display.asyn....

Can we get the shell of running E4 plugin at run-time using any inject logic.

I searched google but no luck in that so far.

Please help

regards
Parvez Ahmad Hakim
