Constructor Detail

AbstractFileNewWizardPage

public AbstractFileNewWizardPage(@NonNull
                                 AbstractFileNewWizard wizard,
                                 @Nullable
                                 org.eclipse.core.resources.IResource initialSelection)

Creates a new complete OCL file creation wizard page. If the initial resource selection contains exactly one container resource then it will be used as the default container resource.

Parameters:

selection - the current resource selection

Method Detail

createControl

public void createControl(org.eclipse.swt.widgets.Composite parent)

(non-Javadoc) Method declared on IDialogPage.

Specified by:

createControl in interface org.eclipse.jface.dialogs.IDialogPage

createNewFile

public org.eclipse.core.resources.IFile createNewFile()

Creates a new complete OCL file resource in the selected container and with the selected name. Creates any missing resource containers along the path; does nothing if the container resources already exist.

In normal usage, this method is invoked after the user has pressed Finish on the wizard; the enablement of the Finish button implies that all controls on on this page currently contain valid values.

Note that this page caches the new complete OCL file once it has been successfully created; subsequent invocations of this method will answer the same file resource without attempting to create it again.

This method should be called within a workspace modify operation since it creates resources.

Returns:

the created file resource, or null if the file was not created

getInitialContents

public java.io.InputStream getInitialContents()

Returns a stream containing the initial contents to be given to new complete OCL file resource instances.

Returns:

initial contents to be given to new complete OCL file resource instances

handleEvent

public void handleEvent(org.eclipse.swt.widgets.Event event)

The WizardNewFileCreationPage implementation of this Listener method handles all events and enablements for controls on this page. Subclasses may extend.

Specified by:

handleEvent in interface org.eclipse.swt.widgets.Listener

initDialog

@NonNull
public AbstractFileDialog initDialog(@Nullable
                                             org.eclipse.core.resources.IResource initialSelection)

setVisible

public void setVisible(boolean visible)

Specified by:

setVisible in interface org.eclipse.jface.dialogs.IDialogPage

Overrides:

setVisible in class org.eclipse.jface.dialogs.DialogPage

validatePage

protected boolean validatePage()

Returns whether this page's controls currently all contain valid values.

Returns:

true if all controls are valid, and false if at least one is invalid
