| Wizard dialogs</h2> |
| <P > |
| The previous example supplied a wizard for a specified extension point. Another, perhaps more common, |
| case is that you want to launch your own plug-in's wizard from some action that you have defined. (In |
| <a HREF="workbench_menus.htm" CLASS="XRef"> Workbench menu contributions</a>, we discuss the ways you can contribute actions to the workbench.) </P> |
| <P >Wizards are displayed in the UI by placing them in a containing |
| dialog. This detail is handled for you when you contribute to a wizard |
| extension. When you are launching your own wizard, you must display it |
| yourself by wrapping it in a <a href="../reference/api/org/eclipse/jface/wizard/WizardDialog.html"><b>WizardDialog</b></a>.</P> |
| <P > |
| For example, the <b> ReadmeCreationWizard</b> could be launched independently by creating a wizard dialog and associating it with the |
| <b>ReadmeCreationWizard</b>. The following code snippet shows how this could be done from some action delegate. (The method assumes that we know the workbench and the selection.)</P> |
| <pre> |
| public void run(IAction action) { |
| // Create the wizard |
| ReadmeCreationWizard wizard = new ReadmeCreationWizard(); |
| wizard.init(getWorkbench(), selection); |
| |
| // Create the wizard dialog |
| WizardDialog dialog = new WizardDialog |
| (getWorkbench().getActiveWorkbenchWindow().getShell(),wizard); |
| // Open the wizard dialog |
| dialog.open(); |
| }</pre> |
| <p>If you need to embed a wizard anywhere else in your plug-in's user |
| interface, the interface <a href="../reference/api/org/eclipse/jface/wizard/IWizardContainer.html"><b>IWizardContainer</b></a> |
| defines the necessary protocol for hosting a wizard.</p> |
