  1. POLayout issue: autogrow label (SWT)
    text
    copied!<p>I'm using a GridLayout trying to make a label autogrow without hiding anything of its content. Here's a simple code to test: Everytime I press the button the label text grows larger, but only after I resize the window horizontally I get the correct layout. Is there any way to fix this without having to resize the window? I think I've tried every property and I still can't get this working, it's driving me nuts!</p> <p><strong>This is what I got</strong></p> <p><img src="https://i.stack.imgur.com/dNyhu.png" alt="wrong layout"></p> <p><strong>This is how it should be</strong></p> <p><img src="https://i.stack.imgur.com/H6rIO.png" alt="right layout"></p> <pre><code>import org.eclipse.swt.SWT; import org.eclipse.swt.events.SelectionAdapter; import org.eclipse.swt.events.SelectionEvent; import org.eclipse.swt.layout.GridData; import org.eclipse.swt.layout.GridLayout; import org.eclipse.swt.widgets.Button; import org.eclipse.swt.widgets.Display; import org.eclipse.swt.widgets.Label; import org.eclipse.swt.widgets.List; import org.eclipse.swt.widgets.Shell; public class UItest { protected Shell shell; private Label label; public static void main(String[] args) { try { UItest window = new UItest(); window.open(); } catch (Exception e) { e.printStackTrace(); } } public void open() { Display display = Display.getDefault(); createContents(); shell.open(); shell.layout(); while (!shell.isDisposed()) { if (!display.readAndDispatch()) { display.sleep(); } } display.dispose(); } protected void createContents() { shell = new Shell(); shell.setSize(450, 300); shell.setText("SWT Application"); shell.setLayout(new GridLayout(1, false)); Button button = new Button(shell, SWT.NONE); button.addSelectionListener(new SelectionAdapter() { public void widgetSelected(SelectionEvent arg0) { label.setText(label.getText() + " " + label.getText()); } }); button.setText("New Button"); label = new Label(shell, SWT.WRAP); label.setLayoutData(new GridData(SWT.FILL, SWT.CENTER, false, false, 1, 1)); label.setText("New Label"); List list = new List(shell, SWT.BORDER); list.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true, 1, 1)); } protected Label getLabel() { return label; } } </code></pre> <p><strong>Thanks for your time.</strong></p> <hr> <p><strong>SOLVED WITH THESE CHANGES:</strong></p> <pre><code>Button button = new Button(shell, SWT.NONE); button.addSelectionListener(new SelectionAdapter() { public void widgetSelected(SelectionEvent arg0) { label.setText(label.getText() + " " + label.getText()); shell.layout(); // ADDED THIS } }); button.setText("New Button"); label = new Label(shell, SWT.WRAP); // SET HORIZONTAL GRAB ON LABEL (FIRST TRUE IN GridData CONSTRUCTOR) label.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, false, 1, 1)); label.setText("New Label"); </code></pre>
