     Sets the focus to the source folder's text field.
public void setPackageFragmentRoot(IPackageFragmentRoot root, boolean canBeModified)
     Sets the current source folder (model and text field) to the given package fragment root.
Parameters:
  root - The new root.
Parameters:
  canBeModified - if false the source folder field can not be changed by the user.

Field Detail
CONTAINER
final protected static String CONTAINER(Code)
Id of the container field

fContainerStatus
protected IStatus fContainerStatus(Code)
The status of the last validation.

Constructor Detail
NewContainerWizardPage
public NewContainerWizardPage(String name)(Code)
Create a new NewContainerWizardPage
Parameters:
  name - the wizard page's name

Method Detail
chooseContainer
protected IPackageFragmentRoot chooseContainer()(Code)
Opens a selection dialog that allows to select a source container. returns the selected package fragment root or null if the dialog has been canceled.The caller typically sets the result to the container input field.
Clients can override this method if they want to offer a different dialog.

since:
   3.2

containerChanged
protected IStatus containerChanged()(Code)
This method is a hook which gets called after the source folder's text input field has changed. This default implementation updates the model and returns an error status. The underlying model is only valid if the returned status is OK. the model's error status

createContainerControls
protected void createContainerControls(Composite parent, int nColumns)(Code)
Creates the necessary controls (label, text field and browse button) to edit the source folder location. The method expects that the parent composite uses a GridLayout as its layout manager and that the grid layout has at least 3 columns.
Parameters:
  parent - the parent composite
Parameters:
  nColumns - the number of columns to span. This number must begreater or equal three

getContainerLabel
protected String getContainerLabel()(Code)
Returns the label that is used for the container input field. the label that is used for the container input field.
since:
   3.2

getCurrentTextSelection
protected ITextSelection getCurrentTextSelection()(Code)
Returns the text selection of the current editor. null is returned when the current editor does not have focus or does not return a text selection. Returns the text selection of the current editor or null.
since:
   3.0

Utility method to inspect a selection to find a Java element.
Parameters:
  selection - the selection to be inspected a Java element to be used as the initial selection, or null,if no Java element exists in the given selection

getJavaProject
public IJavaProject getJavaProject()(Code)
Returns the Java project of the currently selected package fragment root or null if no package fragment root is configured. The current Java project or null.
since:
   3.3

getMaxFieldWidth
protected int getMaxFieldWidth()(Code)
Returns the recommended maximum width for text fields (in pixels). This method requires that createContent has been called before this method is call. Subclasses may override to change the maximum width for text fields. the recommended maximum width for text fields.

getPackageFragmentRoot
public IPackageFragmentRoot getPackageFragmentRoot()(Code)
Returns the IPackageFragmentRoot that corresponds to the current value of the source folder field. the IPackageFragmentRoot or null if the current sourcefolder value is not a valid package fragment root
