自定义布局Java Swing

Question

I want to make board(map) like this in Java.

Each small hexagon is image.

Suppose I have two Java classes. Canvas(big hexagon) and Hexagon. First is entire board from which I generate randomly all small hexagons. Both classes derived from JPanel. Now I have GridLayout. How can I arrange layout like this?

Answer 1

Why do you need the small hexagon panels? I would rather just define List (list of Hexagons) each with desired position and just override paintComponent() method of main JPanel . You can use this http://java-sl.com/shapes.html to create hexagon shapes.

To track mouse click you can use contains() method of Shape.

Answer 2

you can

1) common way

• by painting to the JPanel/JComponent by override paintComponent() (I asumed that there are Image/BufferedImage/Icon/ImageIco n)

2) by place Icon/ImageIcon to the JLabel

• you have look at JLayer (since Java7) or use (former) JXLayer

• OverlayLayout or customizations for OverlayLayout by @camickr

Answer 3

The point of layout manages is to make it possible for the layout to auto-adjust when components change their size or the window does.

It looks like your hexagons will always be the same size, so you really don't need a layout manager, and positioning the hexagons absolutely should be fine.
