Void fillOval(double topX, double topY, double width, double height) StrokeOval(double topX, double topY, double width, double height) The current fill can be as simple asĮither strokeOval( ) or fillOval( ), shown next: void The strokeRect( ) method draws the outline of a rectangle using theįills the rectangle with the current fill. Void fillRect(double topX, double topY, double width, double height)
StrokeRect(double topX, double topY, double width, double height) It draws a line from startX, startY to endX, endY, using the current stroke, whichĬan be a solid color or some more complex style.Įither strokeRect( ) or fillRect( ), shown here: void Void strokeLine(double startX, double startY, double endX, You can draw a line using strokeLine( ), shown here: Our purposes, we will use only a few of its methods, but they will give you a Your future, you will definitely want to study its capabilities closely. If sophisticated graphics programming is in GraphicsContext defines a large number of methods that draw To obtain a GraphicsContext that refers to a Thus it can be used as a node in a scene graph. First, you must create a Canvas instance. Something, such as a line, on a canvas, JavaFX automatically renders itĬanvas, you must perform two steps. These methods can be used to draw directly on the surface of a canvas, which isĮncapsulated by the Canvas class in.
Objects, such as lines, circles, and rectangles. Rendering is automatic.Īpproach to rendering is especially helpful is when displaying graphics This approach, there is no need to call a method like repaint( ). Keeps track of what you display in a scene and redisplays that scene as needed. JavaFX eliminates this tedious mechanism because it Your application needs to store the window contents, redrawing them when This is one of the most important ways that JavaFX improves on Swing.Īs you may know, in Swing or the AWT, you must call the repaint( ) method to cause a window to be repainted. Handles rendering tasks for you automatically, rather than you handling them
