SWT - Simples Layout Problem

[Solour]

Hey,

ich versuch jetzt seid mehr als einer stunde diese zwei buttons vernünftig zu layouten...
die sollen einfach beide gleichbreit sein _und_ zusammen so breit wie das fenster sein.
eigentlich nicht so schwer vom gedanken her... aber in SWT.. :bahnhof:

hoffentlich kennt sich da jemand besser aus als ich

ciao

	public void show() {
		final Display display = new Display();
		final Shell shell = new Shell(display);
		shell.setSize(350, 280);
		shell.setLayout(new RowLayout());
		
		final Button bAccept;
		final Button bAbort;
		{
			final Composite buttonArea = new Composite(shell, SWT.NULL);
			bAccept = new Button(buttonArea, SWT.PUSH);
			bAccept.setText("Accept");
			GridData gd = new GridData();
			gd.horizontalAlignment = SWT.FILL;
			gd.grabExcessHorizontalSpace = true;
			bAccept.setLayoutData(gd);
			bAbort = new Button(buttonArea, SWT.PUSH);
			bAbort.setText("Abort");
			gd = new GridData();
			gd.horizontalAlignment = SWT.FILL;
			gd.grabExcessHorizontalSpace = true;
			bAccept.setLayoutData(gd);

			GridLayout gridLayout = new GridLayout();
			buttonArea.setLayout(gridLayout);
			gridLayout.numColumns = 2;
			buttonArea.layout(true, true);
		}
		shell.open();
		while (!shell.isDisposed()) {
			if (!display.readAndDispatch())
				display.sleep();
		}
		display.dispose();
	}

	public static void main(String[] args) {
		new SWT_TEST().show();
	}

...
buttonArea.setLayout(new FormLayout());

FormData data = new FormData();
data.top = new FormAttachment(0, 0);
data.left = new FormAttachment(0, 0);
data.right = new FormAttachment(50, 0);
bAccept.setLayoutData(data);

data = new FormData();
data.top = new FormAttachment(0, 0);
data.left = new FormAttachment(bAccept, 0);
data.right = new FormAttachment(100, 0);
bAbort.setLayoutData(data);

Hey,

leider ist SWT immernoch ne totale black box für mich
dein code wird sicher funktionieren, aber was sind die ... ??

	public void show() {
		final Display display = new Display();
		final Shell shell = new Shell(display);
		shell.setSize(350, 280);
		shell.setLayout(new RowLayout());
		
		final Button bAccept;
		final Button bAbort;
		{
			final Composite buttonArea = new Composite(shell, SWT.NULL);
			bAccept = new Button(buttonArea, SWT.PUSH);
			bAccept.setText("Accept");
			bAbort = new Button(buttonArea, SWT.PUSH);
			bAbort.setText("Abort");
			
			buttonArea.setLayout(new FormLayout());

			FormData data = new FormData();
			data.top = new FormAttachment(0, 0);
			data.left = new FormAttachment(0, 0);
			data.right = new FormAttachment(50, 0);
			bAccept.setLayoutData(data);

			data = new FormData();
			data.top = new FormAttachment(0, 0);
			data.left = new FormAttachment(bAccept, 0);
			data.right = new FormAttachment(100, 0);
			bAbort.setLayoutData(data);
			
			buttonArea.layout(true, true);
		}
		shell.open();
		while (!shell.isDisposed()) {
			if (!display.readAndDispatch())
				display.sleep();
		}
		display.dispose();
	}

	public static void main(String[] args) {
		new SWT_TEST().show();
	}

Bitte was ist was? Hab die Frage jetzt nicht verstanden. :roll:

 

[Solour]

hey,

in deiner zeile 1
ich weiß nicht was ich sonst tun muss, um dein code-snippet zu verwenden..

ciao

Achso das meinst Du. Die Frage erübrigt sich eigtl. denn der Code von Dir sieht doch gut aus. Lass es doch mal laufen, sollte funktionieren.

 

[Solour]

hehe

ich hätt den code nicht gepostet, wenn es klappen würd

die hocken beide in der oberen linken ecke..
also
-----------------------------------------------------
| Abort | Accept |
----------------------
|
|
|
|----------------------------------------------------

was ich z.b. überhaupt nicht weiß:

• muss SWT.NULL beim composite erstellen sein, oder doch etwas anderes?
• muss man die composite-größe setzen?

 

[byte]

Dann gib der Shell doch auch ein FormLayout und ziehe das Composite über das ganze Fenster:

shell.setLayout(new FormLayout());

...

data.top = new FormAttachment(0, 0);
data.left = new FormAttachment(0, 0);
data.right = new FormAttachmen(100, 0);
data.bottom = new FormAttachment(100, 0);
buttonArea.setLayoutData(data);

uff...

das hatte sogar so irgendwie geklappt..
aber ich hab mein problem vermutlich etwas zu stark vereinfacht:
so soll es aussehen:

-------------------------------------------------------|
|                                                      |
|                                                      |
|                 SWT_AWT bridge                       |
|                                                      |
|                                                      |
|------------------------------------------------------|
|        Abort           |                   Accept    |
-------------------------------------------------------|

aber es sieht so aus:

-------------------------------------------------------|
|                                                      |
|                                                      |
|                 SWT_AWT bridge                       |
|                                                      |
|                                                      |
|------------------------------------------------------|
|        Abort           |                   Accept    |
-------------------------------------------------------|
|                                                      |
|                                                      |
|                                                      |
|------------------------------------------------------|

also das untere ding sollte eigentlich am unteren rand hängen..
ja ich weiß, das snippet ist schon seehr groß.. tut mir leid.. :/

hoffentlich hat da einer noch ne idee :?

public class SWT_TEST2 {

	private static SWT_TEST2 instance = null;

	public static SWT_TEST2 getInstance(Shell sh) {
		if (instance == null || instance.getShell().isDisposed())

		return instance;
	}

	private Shell dialog;

	private SWT_TEST2(final Shell sh, String title) {
		dialog = new Shell(sh, SWT.DIALOG_TRIM | SWT.APPLICATION_MODAL);
		dialog.setSize(500, 300);
		dialog.setLayout(new FormLayout());
		final Composite cBridge;
		{
			cBridge = new Composite(dialog, SWT.EMBEDDED);
			final Frame f = SWT_AWT.new_Frame(cBridge);
			// f.add(mainPanel);
			JPanel pan = new JPanel();
			JButton bButton1 = new JButton("Button1");
			JButton bButton2 = new JButton("Button2");
			pan.add(bButton1);
			pan.add(bButton2);
			f.add(pan);
			f.setVisible(true);
			f.pack();
			FormData data = new FormData();
			data.top = new FormAttachment(0, 0);
			data.left = new FormAttachment(0, 0);
			data.right = new FormAttachment(100, 0);
			cBridge.setLayoutData(data);
		}
		final Button bAccept;
		final Button bAbort;
		{
			final Composite buttonArea = new Composite(dialog, SWT.NULL);
			bAccept = new Button(buttonArea, SWT.PUSH);
			bAccept.setText("Accept");
			bAbort = new Button(buttonArea, SWT.PUSH);
			bAbort.setText("Abort");

			buttonArea.setLayout(new FormLayout());

			FormData data = new FormData();
			data.top = new FormAttachment(0, 0);
			data.left = new FormAttachment(0, 0);
			data.right = new FormAttachment(50, 0);
			bAccept.setLayoutData(data);

			data = new FormData();
			data.top = new FormAttachment(0, 0);
			data.left = new FormAttachment(bAccept, 0);
			data.right = new FormAttachment(100, 0);
			bAbort.setLayoutData(data);

			data = new FormData();
			data.top = new FormAttachment(cBridge);
			data.left = new FormAttachment(0, 0);
			data.right = new FormAttachment(100, 0);
			data.bottom = new FormAttachment(100, 0);
			buttonArea.setLayoutData(data);
			buttonArea.layout(true, true);
		}
		Listener listener = new Listener() {
			public void handleEvent(Event event) {
				if (event.widget == bAccept) {
					tearDown(true);
				} else if (event.widget == bAbort) {
					tearDown(false);
				}
			}
		};
		bAccept.addListener(SWT.Selection, listener);
		bAbort.addListener(SWT.Selection, listener);
		dialog.setLocation(0, 0);
	}

	public Shell getShell() {
		return dialog;
	}

	private boolean accepted = false;

	private void tearDown(boolean accepted) {
		this.accepted = accepted;
		dialog.setVisible(false);
	}

	public static void main(String[] args) {
		Display display = new Display();
		Shell shell = new Shell(display);
		SWT_TEST2 dialog = SWT_TEST2.getInstance(shell);
		Shell dialogShell = dialog.getShell();
		dialogShell.open();
		while (!dialogShell.isDisposed() && dialogShell.isVisible())
			if (!display.readAndDispatch())
				display.sleep();
	}

}
