  • All Implemented Interfaces:
    IDialogPage, IMessageProvider, IWizardPage

    public abstract class AbstractVMInstallPage
    extends WizardPage
    A wizard page used to edit the attributes of an installed JRE. A page is provided by JDT to edit standard JREs, but clients may contribute a custom page for a VM install type if required.

    A VM install page is contributed via the vmInstallPages extension point. Following is an example definition of a VM install page.

     <extension point="org.eclipse.jdt.debug.ui.vmInstallPages">
       <vmInstallPage
          vmInstallType="org.eclipse.jdt.launching.EEVMType"
          class="org.eclipse.jdt.internal.debug.ui.jres.EEVMPage">
       </vmInstallPage>
     </extension>
     
    The attributes are specified as follows:
    • vmInstallType Specifies the VM install type this wizard page is to be used for. Unique identifier corresponding to an IVMInstallType's id.
    • class Wizard page implementation. Must be a subclass of org.eclipse.jdt.debug.ui.launchConfigurations.AbstractVMInstallPage.

    Clients contributing a custom VM install page via the vmInstallPages extension point must subclass this class.
