SWT Style Flag - which are applicable for a composite?

after googleing a bit im stuck in finding out which SWT. flags I can use for a composite. The reference here Ref does not give me any idea...e.g. the constructor details list NO_BACKGROUND, NO_FOCUS, NO_MERGE_PAINTS, NO_REDRAW_RESIZE, NO_开发者_StackOverflow中文版RADIO_GROUP, EMBEDDED, DOUBLE_BUFFERED but you can also pass SWT.BORDER, and it has an effect. Maybe someone can tell me where to find, or, what keywords I should google. I used "swt composite styles" but...;-(

You can see that you can use SWT.BORDER because Control provides it and Composite is a subclass of Control.

As far as I see you can use the following in addition to those given in the documentation to Composite:

• from Scrollable:
  • SWT.H_SCROLL
  • SWT.V_SCROLL
• from Control:
  • SWT.LEFT_TO_RIGHT
  • SWT.RIGHT_TO_LEFT
  • SWT.BORDER

More styles are used by the superclasses of Composite.

Here's what I found so far:

• org.eclipse.swt.widgets.Control
  • SWT.BORDER
  • SWT.LEFT_TO_RIGHT
  • SWT.RIGHT_TO_LEFT
• org.eclipse.swt.widgets.Scrollable
  • SWT.H_SCROLL
  • SWT.V_SCROLL
• org.eclipse.swt.widgets.Composite
  • SWT.NO_BACKGROUND
  • SWT.NO_FOCUS
  • SWT.NO_MERGE_PAINTS
  • SWT.NO_REDRAW_RESIZE
  • SWT.NO_RADIO_GROUP
  • SWT.EMBEDDED
  • SWT.DOUBLE_BUFFERED

These are the styles mentioned in the javadoc for the constructors of the classes. Looking at the source code would show if there are more 'hidden' styles.

A composite can use two kind of style, one is its own, others is inherited from super class.

Composite

• SWT.NO_BACKGROUND
• SWT.NO_FOCUS
• SWT.NO_REDRAW_RESIZE
• SWT.NO_MERGE_PAINTS
• SWT.NO_RADIO_GROUP
• SWT.EMBEDDED
• SWT.DOUBLE_BUFFERED
• SWT.UP

And styles from superclass:

org.eclipse.swt.widgets.Scrollable

• H_SCROLL
• V_SCROLL

org.eclipse.swt.widgets.Control

• SWT.BORDER,
• SWT.LEFT_TO_RIGHT
• SWT.RIGHT_TO_LEFT

org.eclipse.swt.widgets.Widget

• SWT.NONE

The eclipse wiki has listed the style for composite as well as other widgets, you can refer to this document:https://wiki.eclipse.org/SWT_Widget_Style_Bits
