How to set a JavaFX Stage/Frame to Maximized

I'm using JavaFX 2. I want my frame to open maximized but I'm not seeing a way. I searched a bit on the internet without success. For the stage I see setFullScreen() and setIconified() but I don't see anything like setMaximized().

I tried writing primaryStage.setMaximized(true); after writing the getVisualBounds logic. I created a method that looked like this:

public static void maximizeStage() {
    Screen screen = Screen.getPrimary();
    Rectangle2D bounds = screen.getVisualBounds();

    primaryStage.setX(bounds.getMinX());
    primaryStage.setY(bounds.getMinY());
    primaryStage.setWidth(bounds.getWidth());
    primaryStage.setHeight(bounds.getHeight());

    primaryStage.setMaximized(true); // Added setMaximized()
}

This worked for me. It creates an UNMAXIMIZED window with the size of the screen & then proceeds to truly maximize it.

try this simpler code primaryStage.setMaximized(true); and it fills up the whole screen . note that if you remove maximize/minise buttons the application will fill the whole screen as well as remove the taskbar so mnd your initStyles if you have any

Better use Multi-Screen compatible maximize logic:

// Get current screen of the stage      
ObservableList<Screen> screens = Screen.getScreensForRectangle(new Rectangle2D(stage.getX(), stage.getY(), stage.getWidth(), stage.getHeight()));

// Change stage properties
Rectangle2D bounds = screens.get(0).getVisualBounds();
stage.setX(bounds.getMinX());
stage.setY(bounds.getMinY());
stage.setWidth(bounds.getWidth());
stage.setHeight(bounds.getHeight());

The Java 8 implementation of the Stage class provides a maximized property, which can be set as follows:

primaryStage.setMaximized(true);

Use this to remove the Minimise, Maximise Buttons :

primaryStage.initStyle(StageStyle.UTILITY);

Where primaryStage is your Stage object.

When evaluating the sourcecode of the Ensemble.jar provided with the samples of JavaFX 2.0 SDK, the currently valid way to achieve window maximizing is

Screen screen = Screen.getPrimary();
Rectangle2D bounds = screen.getVisualBounds();

primaryStage.setX(bounds.getMinX());
primaryStage.setY(bounds.getMinY());
primaryStage.setWidth(bounds.getWidth());
primaryStage.setHeight(bounds.getHeight());

(you find similar code in WindowButtons.java)

The 'maximize' button is still enabled and when clicking it, the windows will grow a bit more (Windows OS). After this the 'maximize 'button is disabled. In the provided example the standard buttons are replaced. Maybe this is still an issue.
