这是一个简单的示例,它应该解释如何跨 a 的多个列跨越一个小部件GridLayout
:
public class StackOverflow2
{
public static void main(String[] args)
{
final Display display = new Display();
final Shell shell = new Shell(display);
shell.setText("StackOverflow");
shell.setLayout(new GridLayout(3, false));
Label firstLabel = new Label(shell, SWT.NONE);
firstLabel.setText("Label");
Text firstText = new Text(shell, SWT.BORDER);
addSpanData(firstText, 2);
Label secondLabel = new Label(shell, SWT.NONE);
secondLabel.setText("Label");
Text secondText = new Text(shell, SWT.BORDER);
addSpanData(secondText, 1);
Text thirdText = new Text(shell, SWT.BORDER);
addSpanData(thirdText, 1);
Label thirdLabel = new Label(shell, SWT.NONE);
thirdLabel.setText("Label");
Text fourthText = new Text(shell, SWT.BORDER);
addSpanData(fourthText, 2);
shell.pack();
shell.open();
while (!shell.isDisposed())
{
if (!display.readAndDispatch())
display.sleep();
}
display.dispose();
}
private static void addSpanData(Control comp, int span)
{
GridData data = new GridData(SWT.FILL, SWT.CENTER, true, false);
data.horizontalSpan = span;
comp.setLayoutData(data);
}
}
这是它的外观:
