Eclipse UA gurus: What's the best or right way to hook my own help topic to the ? button for my own [message #472331]

Hi,

If I have created my own wizard or wizard dialog, what do I need to do
to have the ? button open to my own help topic?

If it's via context ids, then how do you register the context id for a
wizard?

I found these two eclipse.platform newsgroup postings:
http://dev.eclipse.org/newslists/news.eclipse.platform/msg60 928.html
and
http://dev.eclipse.org/newslists/news.eclipse.platform/msg60 929.html

The second one says that you have to override the DialogPage method
public void performHelp()
{
PlatformUI.getWorkbench().getHelpSystem().displayHelp(contex tID);
}

Is that the best way? The 'right' way to do it?

Thanks!

Lee Anne,

We set the context id in our wizard page.

public class MyWizardPage extends WizardPage
public void createControl(Composite parent) {
PlatformUI.getWorkbench.getHelpSystem.setHelp(parent,
MyPluginActivator.ID + ".mycontexthelpid");
}
}

and we set help for the wizard dialog.

WizardDialog dialog = new WizardDialog(.....);
PlatformUI.getWorkbench().getHelpSystem().setHelp(dialog.get Shell(),
"mycontexthelp.id");

We don't override performHelp().

As for the help context id. Define a context xml file in your plugin.

<?xml version="1.0" encoding="UTF-8"?>
<?NLS TYPE="org.eclipse.help.contexts"?>
<contexts>
<context id="mycontexthelpid" >
<description>My wizard help.</description>
<topic label="Wizard help" href="reference/wizard/help.xhtml"/>
</context>
</contexts>

in your plugin

<plugin>
<extension point="org.eclipse.help.contexts">
<contexts file="mywizard.xml" plugin="com.mypluginid"/>
</extension>
</plugin>

A common problem is messing up the plugin and context help ids. You can set
a couple of break points to see which context id is being requested (see my
blog).
