Eclipse Plugin - How to open a wizard page in a command handler? - plugins

Question

I write a plugin for eclipse. I have a button in the toolbar menu. and I want that on pressing on it - a wizard page dialog will be opened. I wrote already a class which extends wizard and implements IWizardPage, and I wrote also all the 5 relevant pages, I only don't find any way to open this in the command handler.
Here is the pieces of my code:
The command handler:
public class AddProjectHandler extends AbstractHandler {
#Override
public Object execute(ExecutionEvent event) throws ExecutionException {
return null;
}
}
The wizard page manager:
public class NewProjectWizardManager extends Wizard implements INewWizard {
private NewProjectWizardPage1 _page1;
private NewProjectWizardPage2 _page2;
private NewProjectWizardPage3 _page3;
private NewProjectWizardPage4 _page4;
private NewProjectWizardPage5 _page5;
// constructor
public NewProjectWizardManager() {
super();
setWindowTitle("New Project");
}
#Override
public void init(IWorkbench workbench, IStructuredSelection selection) {
}
#Override
public boolean performCancel() {
return true;
}
#Override
public void addPages() {
super.addPages();
_page1 = new NewProjectWizardPage1();
addPage(_page1);
_page2 = new NewProjectWizardPage2(_page1);
addPage(_page2);
_page3 = new NewProjectWizardPage3(_page1);
addPage(_page3);
_page4 = new NewProjectWizardPage4();
addPage(_page4);
_page5 = new NewProjectWizardPage5(_page1);
addPage(_page5);
}
#Override
public boolean canFinish() {
IWizardContainer container = getContainer();
if (_page5.equals(container.getCurrentPage())) {
return true;
} else {
return false;
}
}
#Override
public IWizardPage getNextPage(IWizardPage page) {
IWizardPage nextPage = super.getNextPage(page);
IWizardContainer container = getContainer();
if (nextPage != null) {
if (_page2.equals(container.getCurrentPage()) && _page2.isCheckFinishChecked())
nextPage = super.getNextPage(super.getNextPage(nextPage));
}
return nextPage;
}
#Override
public boolean performFinish() {
}
}
The plugin.xml pieces:
<command
categoryId="com.commands.category"
description="Add new Project"
id="com.commands.AddProject"
name="Add new Project">
</command>
<handler
class="com.handlers.AddProjectHandler"
commandId="com.commands.AddProject">
</handler>
Do you have any idea?

Answer 1

Use WizardDialog to show a wizard. Something like:
public Object execute(ExecutionEvent event) throws ExecutionException
{
Shell activeShell = HandlerUtil.getActiveShell(event);
IWizard wizard = new NewProjectWizardManager();
WizardDialog dialog = new WizardDialog(activeShell, wizard);
dialog.open();
return null;
}

Answer 2

I found the code below from org.eclipse.jdt.ui.actions.AbstractOpenWizardAction.
Before Eclipse3.4 you can extend this class to create an Action.but action is deprecated now,I wonder if Eclipse.org provide something like AbstractOpenWizardAction to do the same work in command-handler mode. I'v not found it yet.
public void run() {
Shell shell = getShell();
if (!(doCreateProjectFirstOnEmptyWorkspace(shell)))
return;
try {
INewWizard wizard = createWizard();
wizard.init(PlatformUI.getWorkbench(), getSelection());
WizardDialog dialog = new WizardDialog(shell, wizard);
PixelConverter converter = new PixelConverter(JFaceResources.getDialogFont());
dialog.setMinimumPageSize(converter.convertWidthInCharsToPixels(70),
converter.convertHeightInCharsToPixels(20));
dialog.create();
int res = dialog.open();
if ((res == 0) && (wizard instanceof NewElementWizard)) {
this.fCreatedElement = ((NewElementWizard) wizard).getCreatedElement();
}
notifyResult(res == 0);
} catch (CoreException e) {
String title = NewWizardMessages.AbstractOpenWizardAction_createerror_title;
String message = NewWizardMessages.AbstractOpenWizardAction_createerror_message;
ExceptionHandler.handle(e, shell, title, message);
}
}
