如何正确对齐Java SWT应用程序中的复选框

Question

如何在我的Java SWT应用程序中右键对齐复选框？这是我的代码片段:

    Button checkFullECR = new Button(scrolledForm.getBody(), SWT.CHECK);
    checkFullECR.setAlignment(SWT.RIGHT);
    checkFullECR.setBackground(SWTResourceManager.getColor(SWT.COLOR_WHITE));
    checkFullECR.setText("I need the complete ECR/ECN Process:");

它看起来如下:

[ ] I need the complete ECR/ECN Process:

我希望它看起来像:

I need the complete ECR/ECN Process:       [ ]

Answer 1

你不能只使用一个Button控件,你需要使用一个Label文本和一个复选框Button,没有文本排列在两列.

就像是:

Composite body = new Composite(parent, SWT.NONE);

body.setLayout(new GridLayout(2, false));

Label label = new Label(body, SWT.LEFT);
label.setText("I need the complete ECR/ECN Process:");

Button checkFullECR = new Button(body, SWT.CHECK);

... more label / button pairs ....

有一次,我有点不同意格雷格.

您可以使用setOrientation(int)的方法Button来强制从右到左的布局:

public static void main(String[] args)
{
    Display display = new Display();
    final Shell shell = new Shell(display);
    shell.setLayout(new GridLayout());

    Button button = new Button(shell, SWT.CHECK);
    button.setText("TEST");

    button = new Button(shell, SWT.CHECK);
    button.setOrientation(SWT.RIGHT_TO_LEFT);
    button.setText("TEST");

    shell.pack();
    shell.open();

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

    display.dispose();
}

看起来像这样:
