open

public int open()
Description copied from class: Window
Opens this window, creating it first if it has not yet been created.

If this window has been configured to block on open ( setBlockOnOpen), this method waits until the window is closed by the end user, and then it returns the window's return code; otherwise, this method returns immediately. A window's return codes are window-specific, although two standard return codes are predefined: OK and CANCEL.

Overrides:
open in class Window
Returns:
the return code
See Also:
Window.create()

cancelPressed

protected void cancelPressed()
Handles cancel button pressed event.

Overrides:
cancelPressed in class Dialog

computeResult

protected void computeResult()
Description copied from class: SelectionStatusDialog
Compute the result and return it.

Specified by:
computeResult in class SelectionStatusDialog

create

public void create()
Description copied from class: Window
Creates this window's widgetry in a new top-level shell.

The default implementation of this framework method creates this window's shell (by calling createShell), and its controls (by calling createContents), then initializes this window's shell bounds (by calling initializeBounds).

Overrides:
create in class SelectionStatusDialog

createDialogArea

protected 
Control createDialogArea(
Composite parent)
Description copied from class: Dialog
Creates and returns the contents of the upper part of this dialog (above the button bar).

The Dialog implementation of this framework method creates and returns a new Composite with standard margins and spacing.

The returned control's layout data must be an instance of GridData. This method must not modify the parent's layout.

Subclasses must override this method but may call super as in the following example:

 Composite composite = (Composite) super.createDialogArea(parent);
 //add controls to composite as necessary
 return composite;
 

Overrides:
createDialogArea in class Dialog
Parameters:
parent - the parent composite to contain the dialog area
Returns:
the dialog area control

createTreeViewer

protected 
TreeViewer createTreeViewer(
Composite parent)
Creates and initializes the tree viewer.

Parameters:
parent - the parent composite
Returns:
the tree viewer
See Also:
doCreateTreeViewer(Composite, int)

doCreateTreeViewer

protected 
TreeViewer doCreateTreeViewer(
Composite parent,
                                        int style)
Creates the tree viewer.

Parameters:
parent - the parent composite
style - the SWT style bits
Returns:
the tree viewer
Since:
3.4

getTreeViewer

protected 
TreeViewer getTreeViewer()
Returns the tree viewer.

Returns:
the tree viewer

access$superButtonPressed

protected void access$superButtonPressed(int id)
Set the result using the super class implementation of buttonPressed.

Parameters:
id -
See Also:
Dialog.buttonPressed(int)

access$setResult

protected void access$setResult(
List result)
Set the result using the super class implementation of setResult.

Parameters:
result -
See Also:
SelectionStatusDialog.setResult(int, Object)

handleShellCloseEvent

protected void handleShellCloseEvent()
Description copied from class: Window
Notifies that the window's close button was pressed, the close menu was selected, or the ESCAPE key pressed.

The default implementation of this framework method sets the window's return code to CANCEL and closes the window using close. Subclasses may extend or reimplement.

Overrides:
handleShellCloseEvent in class Window
See Also:
Window.handleShellCloseEvent()
