[news.eclipse.platform.swt] Re: How to set the row height in a Table?

[Wayne Beaton <wayne@xxxxxxxxxxx>]

Different row heights works fine on Linux. I'm quite sure that I've seen
it on Windows as well.

Try modifying SWT Snippet 271 [1] to set the height to different values.

ackage org.eclipse.swt.snippets;

public class Snippet271 {

public static void main(String[] args) {
	Display display = new Display();
	Shell shell = new Shell(display);
	shell.setBounds(10,10,200,250);
	final Table table = new Table(shell, SWT.NONE);
	table.setBounds(10,10,150,200);
	table.setLinesVisible(true);
	for (int i = 0; i < 5; i++) {
		TableItem tableItem = new TableItem(table, SWT.NONE);
		tableItem.setData(i);
		tableItem.setText("item " + i);
	}

	/*
	 * NOTE: MeasureItem is called repeatedly.  Therefore it is critical
	 * for performance that this method be as efficient as possible.
	 */
	table.addListener(SWT.MeasureItem, new Listener() {
		public void handleEvent(Event event) {
			int clientWidth = table.getClientArea().width;
			event.height = (Integer)(event.item.getData()) * 10;
			event.width = clientWidth * 2;
		}
	});

	shell.open();
	while (!shell.isDisposed()) {
		if (!display.readAndDispatch()) display.sleep();
	}
	display.dispose();
}
}
