Add Xtext content to toolbar [message #1815971]

Hello everyone,

I have followed this example and I was able to add a preference setting "icon" to the toolbor.

Now, I wish to further extend this. I have created a new file wizard and new project wizard.
I wish to create dedicated icons for these functionalities on the toolbar.

My question is: How can I create command for MyDslProjectTemplateProvider and MyDslFileTemplateProvider or how to call them in the execute method of MyAbstractHandlerImplementation? (As shown here.)

You may get some insipration from the WizardHandler class.

This class is invoked when the user clicks on the 'Create a plug-in project' button on the toolbar (see screenshot.png).

Thank you for the feedback.

The Xtext generates IFileTemplateProvider and IProjectTemplateProvider. Are their usage similar to the WizardHandler in your example?

As an alternative you can use the org.eclipse.ui.newWizard command (instead of defining your own one) and parameterize that with the wizard Id you want to invoke:

  <extension
       point="org.eclipse.ui.menus">
    <menuContribution
          allPopups="false"
          locationURI="toolbar:org.eclipse.ui.main.toolbar">
       <toolbar
             id="org.eclipse.xtext.example.fowlerdsl.ui.toolbar">
          <!--
            For some reason the tooltip is not shown when hovering over the toolbar button
            See also https://www.eclipse.org/forums/index.php/t/1079111/
          -->           
          <command
                commandId="org.eclipse.ui.newWizard"
                tooltip="Create a statemachine project">
             <parameter
                   name="newWizardId"
                   value="org.eclipse.xtext.example.fowlerdsl.ui.wizard.StatemachineNewProjectWizard">
             </parameter>
          </command>
       </toolbar>
    </menuContribution>
 </extension>

Sorry, I was unclear beforehand... Let me rephrase the question:
I have added fileWizard and projectWizard {generate=true} to the mwe2 file of my language.
This generated org.eclipse.xtext.mydsl.ui.wizard package with MyDslFileTemplateProvider and MyDslProjectTemplateProvider in it (implementing IFileTemplateProvider and IProjectTemplateProvider respectively).

This is working fine, if I select the New -> Other... option, then I can select MyDsl -> MyDsl File and MyDsl Project in it. The files and projects are created properly after selection.

I want to create dedicated buttons on the toolbar for these two selections (wizards).
My question is: How can I do this?

-My first idea was to create a package, where I invoke the MyDslFileTemplateProvider. This is the point, where I have no idea how to do this.

-Afterwards, I have followed the idea of @Tamas and created a parametrized command, Here, I have replaced the org.eclipse.xtext.example.fowlerdsl.ui.wizard.StatemachineNewProjectWizard with org.eclipse.xtext.mydsl.ui.wizard.MyDslFileTemplateProvider, but this unfortunately resulted Eclipse error ("Unable to generate parametrized command..."). However, the icon is on the toolbar, but it is deactivated.
My guess would be that the parametrized command also expects to invoke somehow MyDslFileTemplateProvider. Am I correct here? (I guess this leads to my previous point.)

Instead of

org.eclipse.xtext.example.fowlerdsl.ui.wizard.StatemachineNewProjectWizard

you have to use the id of your generated wizard.

i still dont get it.
how is MyDslFileTemplateProvider involved in the problem at all?
its used by the wizard. it not is the wizard

you simply tell it: use that handler.
and the handler you tell to use the wizard

It is working finally. Thank you a lot for your help.

What I did not understand that you did not understand:
The fileWizard and projectWizard in the mwe2 file generates two files MyDslFileTemplateProvider and MyDslProjectTemplateProvider. These are clearly not wizards...
But in the plugin.xml file MyDslNewFileWizard and MyDslNewProjectWizards are defined! Their ID can be copied from there.

This was maybe trivial for you, but I've struggled with it.

Everything works fine with this information combined with the code of Tamas.

Actually the Xtext team tries to give its best to provide APIs that are self-explanatory. However, if something is understandable for us, it does not mean that it is directly understandable to our users.

That's why such feedbacks from the Xtext users are very valuable to us to know how to improve the Xtext framework in the future!

I created an Xtext issue to extend the Wizard Fragment be able to generate such toolbar buttons for the New Project Wizard / New File Wizard.
