I'm trying to change the background image of a pane when the application is maximized. My background is set using inline css. I set up two different variables and an if statement for the style. However, I'm having no luck getting it to change style.
String cssStyle = "-fx-background-image: url(\'file:images/poker_table.png\');" +
"-fx-background-position: center center;" +
"-fx-background-radius: 15;" + // ************* For rounded corners
"-fx-background-size: 100% 100%;";
String cssStyle2 = "-fx-background-image: url(\'file:images/poker_table.jpg\');" +
"-fx-background-position: center center;" +
"-fx-background-radius: 15;" +
"-fx-background-size: 100% 100%;";
if (!primaryStage.isMaximized())
{ gameScreen.setStyle(cssStyle);
}
else
{ gameScreen.setStyle(cssStyle2);

Just add a listener to the Stage's maximizedProperty(). Properties and listeners are a fundamental part of the JavaFX API: you can find them in the Standards Documentation, or any good JavaFX tutorial.
primaryStage.maximizedProperty().addListener((obs, wasMaximized, isNowMaximized) -> {
if (isNowMaximized) {
gameScreen.setStyle(cssStyle2);
} else {
gameScreen.setStyle(cssStyle);
}
});
You may also want to set appropriate styles immediately using existing code.
You can also use binding if you prefer:
gameScreen.styleProperty().bind(Bindings.createStringBinding(
() -> primaryStage.isMaximized() ? cssStyle2 : cssStyle,
primaryStage.maximizedProperty()
);
Binding replaces your existing code; it is applied immediately and when maxmizedProperty changes.
