Constructor Detail

NewtCanvasSWT

public NewtCanvasSWT(org.eclipse.swt.widgets.Composite parent,
                     int style,
                     Window child)
Instantiates a NewtCanvas with a NEWT child.

Note: The NEWT child Display's EDTUtil is being set to an SWT conform implementation via Display.setEDTUtil(EDTUtil).

Parameters:
parent - the SWT composite
style - additional styles to SWT#NO_BACKGROUND
child - optional preassigned #Window, maybe null
Method Detail

create

public static NewtCanvasSWT create(org.eclipse.swt.widgets.Composite parent,
                                   int style,
                                   Window child)
Creates an instance using NewtCanvasSWT(Composite, int, Window) on the SWT thread.

Note: The NEWT child Display's EDTUtil is being set to an SWT conform implementation via Display.setEDTUtil(EDTUtil).

Parameters:
parent - the SWT composite
style - additional styles to SWT#NO_BACKGROUND
child - optional preassigned #Window, maybe null
Returns:
a new instance

update

public void update()
Overrides:
update in class org.eclipse.swt.widgets.Control

dispose

public void dispose()
Destroys this resource:

Overrides:
dispose in class org.eclipse.swt.widgets.Widget
See Also:
Window.destroy()

getNativeWindow

public NativeWindow getNativeWindow()
Returns:
this SWT Canvas NativeWindow representation, may be null in case it has not been realized.

getDefaultCloseOperation

public WindowClosingProtocol.WindowClosingMode getDefaultCloseOperation()
Specified by:
getDefaultCloseOperation in interface WindowClosingProtocol
Returns:
the current close operation value
See Also:
WindowClosingProtocol.WindowClosingMode.DISPOSE_ON_CLOSE, WindowClosingProtocol.WindowClosingMode.DO_NOTHING_ON_CLOSE

setDefaultCloseOperation

public WindowClosingProtocol.WindowClosingMode setDefaultCloseOperation(WindowClosingProtocol.WindowClosingMode op)
Specified by:
setDefaultCloseOperation in interface WindowClosingProtocol
Parameters:
op - the new close operation value
Returns:
the previous close operation value
See Also:
WindowClosingProtocol.WindowClosingMode.DISPOSE_ON_CLOSE, WindowClosingProtocol.WindowClosingMode.DO_NOTHING_ON_CLOSE

setNEWTChild

public Window setNEWTChild(Window newChild)
Sets a new NEWT child, provoking reparenting.

A previously detached newChild will be released to top-level status and made invisible.

Note: When switching NEWT child's, detaching the previous first via setNEWTChild(null) produced much cleaner visual results.

Note: The NEWT child Display's EDTUtil is being set to an SWT conform implementation via Display.setEDTUtil(EDTUtil).

Returns:
the previous attached newt child.

getNEWTChild

public Window getNEWTChild()
Returns:
the current NEWT child

setParent

public boolean setParent(org.eclipse.swt.widgets.Composite parent)
Overrides:
setParent in class org.eclipse.swt.widgets.Control
