How to set minimum-/maximum-size of FileDialog? - SWT - Java

Question

I hava a DirectoryDialog like this:

private static void openFiles() {
    Display display = new Display();
    Shell shell = new Shell(display);
    DirectoryDialog directoryDialog = new DirectoryDialog(shell, SWT.OPEN | SWT.MULTI);
    directoryDialog.setFilterPath("c:\\");
    Files[] files = new File(directoryDialog.open().listFiles());
    shell.close();
    while (!shell.isDisposed()) {
        if (!display.readAndDispatch()) display.sleep();
    }
    display.dispose();
}

And how`can I now for example set the minimum size?

I've tryed out shell.setMinimumSize(500, 500), but it didn't work!

Answer 1

You cannot set the size of a DirectoryDialog. The size and position are determined by the OS.

If you absolutely need to enforce a minimum size, you will need to implement your own. For custom dialogs I would recommend taking a look at a JFace Dialog and its subclasses.

Here is a good article about SWT and JFace dialogs: http://www.vogella.com/tutorials/EclipseDialogs/article.html#jface-dialogs.

I also found a custom directory dialog which is just implemented using a Shell, so you would naturally have full control over size and position: http://esus.com/creating-an-swt-directorydialog/
