[news.eclipse.platform.swt] Re: Text Field with buttons in it

[Artem Redkin <artem@xxxxxxxxx>]

TextField is drawn next to buttons, so if SWT.Border style is set, buttons wil be out of text field frame.

Now on carbon, gtk and win32 control created like this: composite with borderless text field and buttons (i added red background to text field to illustrate this: http://picasaweb.google.com/lh/photo/a5egjEQDuYLjH96WGSA7bQ?feat=directlink). Then with paint listener a frame is drawn around composite, so buttons and text inside it, like this:

composite.addPaintListener(new PaintListener() {

			public void paintControl(PaintEvent e) {

				int [] context = new int [1];
				context[0] = e.gc.handle;
				OS.CGContextSaveGState (context[0]);
				int [] outMetric = new int [1];
				OS.GetThemeMetric (OS.kThemeMetricFocusRectOutset, outMetric);
				CGRect rect = new CGRect ();
				OS.HIViewGetBounds (handle, rect);
				rect.x += outMetric [0] + 1;
				rect.y += outMetric [0];
				rect.width -= outMetric [0] * 2 + 2;
				rect.height -= outMetric [0] * 2;
				int state = 0;
				if (OS.IsControlEnabled (text.handle)) {
					state = OS.IsControlActive (text.handle) ? OS.kThemeStateActive : OS.kThemeStateInactive;
				} else {
					state = OS.IsControlActive (text.handle) ? OS.kThemeStateUnavailable : OS.kThemeStateUnavailableInactive;
				}
				HIThemeFrameDrawInfo info = new HIThemeFrameDrawInfo ();
				info.state = state;
				info.isFocused = text.isFocusControl();
				info.kind = OS.kHIThemeFrameTextFieldSquare;
				OS.HIThemeDrawFrame (rect, info, context [0], OS.kHIThemeOrientationNormal);
				OS.CGContextRestoreGState (context[0]);
				
			}
		});

The problem was that in cocoa there i could not find a method to draw simple frame. And i thought, maybe this design was a bit odd and there is a better way to do text field with buttons.
