将元素添加到Canvas JavaFX

Question

So I want to add elements or items to a canvas through a GraphicsContext . For example, to add a Rectangle, I don't want to use fillRect(...) , I want to create a Rectangle rect = new Rectangle(...) and add it to my GraphicsContext, So I can perform changes on that rect .

Something like this :

Rectangle rect = new Rectangle();
rect.setHeight(100);
rect.setWidth(100);
rect.setFill(Color.BLACK);
DragResizeMod.makeResizable(rect, null);

then added it to

GraphicsContext gc = canvas.getGraphicsContext2D();
gc.add(rect); //somehow

There is a solution which is to use a Pane instead of Canvas but I don't think it the best way, since a GraphicsContext run on a single thread.

Thanks in advance.

Adding Rectangles to a properly configured Pane is the way to go. I don't understand what your problem with this approach is. This is the way JavaFX works and you will probably not be able to change this.
