我已经创建了向导，我希望它始终位于中心位置，有人可以帮助我吗？

private Point getFirstMonitorSize() { // Here Point is org.eclipse.swt.graphics.Point
    Display display = Display.getDefault();
    if (display != null) {
        Monitor[] monitors = display.getMonitors();
        if (monitors.length == 1) {
            Rectangle clientArea = monitors[0].getClientArea();
            return new Point(clientArea.width / 2, clientArea.height / 2);
        }
    }
    return null;
}

我发现这个用于定位，但我不知道如何在向导对话框中使用？

原文

private Point getFirstMonitorSize() { // Here Point is org.eclipse.swt.graphics.Point
    Display display = Display.getDefault();
    if (display != null) {
        Monitor[] monitors = display.getMonitors();
        if (monitors.length == 1) {
            Rectangle clientArea = monitors[0].getClientArea();
            return new Point(clientArea.width / 2, clientArea.height / 2);
        }
    }
    return null;
}

I found out this for positioning but i don't know how to use in wizard dialog?

对于 Eclipse E4，您可以在 E4LifeCycle 类中添加此方法。
这将使您的应用程序成为主监视器的中心。

这将使您的应用程序 shell 位置位于屏幕中心，如果您打开 WizardDialog，在其中设置正确的 parent shell 那么一切都会就位

@Inject
@Optional
public void receiveActiveShell(@Named(IServiceConstants.ACTIVE_SHELL) final Shell shell) {
    try {
        if (shell != null) {
            final Display display = shell.getDisplay();
            final Monitor primary = display.getPrimaryMonitor();
            final Rectangle displayBounds = primary.getBounds();
            shell.setSize(displayBounds.width - 100, displayBounds.height - 100);
            final Point size = shell.getSize();
            Point defaultLocation = new Point((int) (displayBounds.width - size.x) / 2, (int) (displayBounds.height - size.y) / 2);
            shell.setLocation(this.defaultLocation);
        }
    } catch (Exception e) {
        LOGGER.error("Execption ocuured in Active Shell", e); //$NON-NLS-1$
    }
}

For Eclipse E4, you can add this method in your E4LifeCycle class.
This will make your application centre of primary monitor.

This will make your application shell location in centre of screen, this if you open the WizardDialog where you set the proper parent shell then every thing will fall into place

@Inject
@Optional
public void receiveActiveShell(@Named(IServiceConstants.ACTIVE_SHELL) final Shell shell) {
    try {
        if (shell != null) {
            final Display display = shell.getDisplay();
            final Monitor primary = display.getPrimaryMonitor();
            final Rectangle displayBounds = primary.getBounds();
            shell.setSize(displayBounds.width - 100, displayBounds.height - 100);
            final Point size = shell.getSize();
            Point defaultLocation = new Point((int) (displayBounds.width - size.x) / 2, (int) (displayBounds.height - size.y) / 2);
            shell.setLocation(this.defaultLocation);
        }
    } catch (Exception e) {
        LOGGER.error("Execption ocuured in Active Shell", e); //$NON-NLS-1$
    }
}
