I am trying to setup my view with EPartService
, but still getting exception on that line with findPart
call. Am i doing it right way?
Exception:
Caused by: java.lang.IllegalStateException: Application does not have an active window
at org.eclipse.e4.ui.internal.workbench.ApplicationPartServiceImpl.getActiveWindowService(ApplicationPartServiceImpl.java:36)
at org.eclipse.e4.ui.internal.workbench.ApplicationPartServiceImpl.findPart(ApplicationPartServiceImpl.java:87)
Code:
package cz.vutbr.fit.xhriba01.bc.handler;
import javax.inject.Inject;
import javax.inject.Named;
import org.eclipse.e4.core.di.annotations.Execute;
import org.eclipse.e4.ui.services.IServiceConstants;
import org.eclipse.e4.ui.workbench.modeling.EPartService;
import org.eclipse.jface.viewers.TreeViewer;
import org.eclipse.jface.window.Window;
import org.eclipse.swt.widgets.Shell;
import cz.vutbr.fit.xhriba01.bc.ui.ExplorerView;
import cz.vutbr.fit.xhriba01.bc.ui.dialogs.NewFromDirectoryDialog;
public class NewFromDirectoryHandler {
@Inject
private EPartService fPartService;
@Execute
public void execute(@Named(IServiceConstants.ACTIVE_SHELL) Shell shell) {
NewFromDirectoryDialog dialog = new NewFromDirectoryDialog(shell);
dialog.create();
if (dialog.open() == Window.OK) {
String sourceDir = dialog.getSourceDir();
String classDir = dialog.getClassDir();
TreeViewer tv = ((ExplorerView)fPartService.findPart("bc.part.explorer").getObject()).getTreeViewer();
}
}
}
Try injecting the EPartService
as an argument to the execute
method:
@Execute
public void execute(EPartService fPartService, @Named(IServiceConstants.ACTIVE_SHELL) Shell shell)
It is best to avoid injecting fields in a handler as they will only be injected once when the handler is created. Things like EPartService
change as the active part changes.
