如何将JavaFX舞台/框架设置为最大化？[英] How to set a JavaFX Stage/Frame to Maximized

问题描述

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().

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.

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

primaryStage.setMaximized(true);

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());
