How to make SWT button, text and label of the same height on Windows?

Question

I am trying to make a GUI for chatting and I placed three SWT controls in a row.

Unfortunately I can't find beautiful alignment for them.

The following code

    Display display = new Display();
    Shell shell = new Shell(display);
    shell.setLayout(new GridLayout(3, false));

    Label firstLabel = new Label(shell, SWT.NONE);
    firstLabel.setText("PROMPT:");
    firstLabel.setLayoutData(new GridData(SWT.BEGINNING, SWT.CENTER, false, false));

    Text firstText = new Text(shell, SWT.NONE);
    firstText.setText("hello");
    firstText.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, false));

    Button firstButton = new Button(shell, SWT.PUSH);
    firstButton.setText("Say");
    firstButton.setLayoutData(new GridData(SWT.BEGINNING, SWT.CENTER, false, false));

    shell.pack();
    shell.open();
    shell.setSize(400, 300);

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

gives

i.e. text field is as tall as a button but text is not centered vertically inside it.

If code the text following way

    Text firstText = new Text(shell, SWT.NONE);
    firstText.setText("hello");
    firstText.setLayoutData(new GridData(SWT.FILL, SWT.CENTER, true, false));

I will get

The most beautiful result will be given by

    Text firstText = new Text(shell, SWT.BORDER);
    firstText.setText("hello");
    firstText.setLayoutData(new GridData(SWT.FILL, SWT.CENTER, true, false));

which is

but a button is again slightly taller than a text.

UPDATE

People say they have good result on non-windows platforms, but the question is probably how to control padding/margins of SWT controls.

UPDATE 2

Even in best case text field height is smaller that button's on Windows and the result is platform-dependent.

Answer 1

Here is a code example that should give you an idea how to solve your problem:

public static void main(String[] args)
{
    Display display = new Display();
    Shell shell = new Shell(display);
    shell.setLayout(new GridLayout(3, false));

    Label firstLabel = new Label(shell, SWT.NONE);
    firstLabel.setText("PROMPT:");
    firstLabel.setLayoutData(new GridData(SWT.BEGINNING, SWT.CENTER, false, false));

    Text firstText = new Text(shell, SWT.BORDER);
    firstText.setText("hello");
    firstText.setLayoutData(new GridData(SWT.FILL, SWT.CENTER, true, false));

    Button firstButton = new Button(shell, SWT.PUSH);
    firstButton.setText("Say");
    firstButton.setLayoutData(new GridData(SWT.BEGINNING, SWT.CENTER, false, false));

    Label secondLabel = new Label(shell, SWT.NONE);
    secondLabel.setText("PROMPT:");
    secondLabel.setLayoutData(new GridData(SWT.BEGINNING, SWT.CENTER, false, true));

    Text secondText = new Text(shell, SWT.BORDER | SWT.MULTI | SWT.WRAP);
    secondText.setText("hello");
    secondText.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true));

    Button secondButton = new Button(shell, SWT.PUSH);
    secondButton.setText("Say");
    secondButton.setLayoutData(new GridData(SWT.BEGINNING, SWT.CENTER, false, true));

    shell.pack();
    shell.open();
    shell.setSize(400, 300);

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

Looks like this:

Without SWT.BORDER:
