问题 While working in IntelliJ everything worked but after I built jar it stopped. At first, it was just me forgetting to put it in jar build config, but now after making sure it is there, I still can't run it.

问题 The documentation for the clearRect method of GraphicsContext states that it uses the current clip, but this isn't currently working for me. Consider: GraphicsContext context = canvas.getGraphicsContext2D(); context.beginPath(); context.rect(0,0,100,100); //Set the current path to a rectangle context.stroke(); //Highlights where the current path is context.clip(); //Intersect current clip with rectangle context.fillOval(80, 80, 40, 40); //This correctly draws the oval clipped context

问题 I have a ListView with some Labels in it. The labels' width property is bound to the width property of the ListView but they seem to be slightly larger meaning that a horizontal scrollbar is shown on the list view. What I want is to fit the labels in the list view without the scrollbar on the bottom.

问题 When I want to change the background colour of my TextArea in JavaFX (with CSS), many people recommend "-fx-control-inner-background" . But when I look up the Oracle's CSS reference there's no such a thing as "-fx-control-inner-background" ! In fact nowhere, in the Internet I could find a reference on that and yet it works !
