Method Detail

isPageComplete

public boolean isPageComplete()

getParams

public java.util.Map<java.lang.String,java.io.Serializable> getParams()

Gather parameters from the user interface.

Specified by:

getParams in interface UDIGConnectionPage

Overrides:

getParams in class AbstractUDIGImportPage

Returns:

connection parameters from the user interface

shown

public void shown()

Description copied from class: WorkflowWizardPage

Called immediately after a page has been shown in the wizard. At the time this method is called, the page can be sure that its ui has been created (via a call to #createContents()) and that it's state has been set (via #setState()). Default implementation does nothing, subclass should override.

Overrides:

shown in class WorkflowWizardPage

leavingPage

public boolean leavingPage()

Description copied from class: AbstractUDIGImportPage

Called by framework as the page is about to be left.

There are two main use cases for this method. The first is to save settings for the next time the wizard is visited. The other is to perform some checks or do some loading that is too expensive to do every time isPageComplete() is called. For example a database wizard page might try to connect to the database in this method rather than isPageComplete() because it is such an expensive method to call.

Remember that this method is only called when moving forward.

If an expensive method is called make sure to run it in the container:

 getContainer().run(false, cancelable, runnable);
 

Remember to pass in false as the fork parameter so that it blocks until the method has completed executing.

Overrides:

leavingPage in class AbstractUDIGImportPage

Returns:

true if it is acceptable to leave the page false if the page must not be left

createControl

public void createControl(Composite parent)

getResourceIDs

public java.util.Collection<java.net.URL> getResourceIDs()

Description copied from class: AbstractUDIGImportPage

Returns the ids of the GeoResource to use as the "selected" resources. If a non-empty collection is returned then the next states in the wizard "should" use these as the items selected by the user.

Example: The postgis wizard pages permits the user to select the table of interest. When moving to a new state (for example the Resource Selection State in net.refractions.udig.project.ui) that state should use that as the selected IGeoResources if it needs a selection of IGeoResources
In the ResourceSelectionState example it would use this collection and not need to query the user with a wizard page for that input

Specified by:

getResourceIDs in interface UDIGConnectionPage

Overrides:

getResourceIDs in class AbstractUDIGImportPage

Returns:

the ids of the GeoResource to use as the "selected" resources.

handleEvent

public void handleEvent(Event event)
