Re: [pde-ui-dev] Problem to run a wizard plugin
|
Olivier,
The error looks like some of your classes is missing an expected default
constructor. Two classes I would look at are your top-level plug-in class
and the Wizard class. Read the spec and check what is the expected
constructor.

import org.eclipse.ui.IWorkbench;
import org.eclipse.ui.internal.Workbench;
import org.eclipse.ui.wizards.newresource.BasicNewFileResourceWizard;
/**

*/
public class NewMenuWizard extends Wizard{
IWorkbench _workbench ;
IStructuredSelection _selection;
/**
* Constructor for NewMenuWizard.
*/
public NewMenuWizard() {
super();
}
public void init(IWorkbench in_workbench ,
IStructuredSelection
in_selection ){
_workbench = in_workbench;
_selection = in_selection;
}
/**
* @see org.eclipse.jface.wizard.IWizard#performFinish()
*/
public boolean performFinish() {
return false;
}
/**
* @see org.eclipse.jface.wizard.IWizard#addPages()
*/
public void addPages() {
NewMenuPage nmp = new NewMenuPage( "Criação de
Menu" ,
_selection );
addPage( nmp );
}
public static void main(String[] args) {
// Create the wizard
NewMenuWizard wizard = new NewMenuWizard();
wizard.init(null, null);
// Create the wizard dialog
WizardDialog dialog = new WizardDialog
(null,wizard);
// Open the wizard dialog
dialog.open();
}
