Make the top left of a JFrame (0,0)

Question

我正在JFrame中进行平铺，我只是认为如果地图的左上角是（0,0）会更容易处理，因为它可以更轻松地通过2d数组解释位置。

Answer 1

I'm doing some tiling in a JFrame

You should NOT be doing tiling in the frame.

Instead you add a JPanel to the frame and do the tiling in the panel. Then the top/left of the panel will be(0, 0).

Read the section from the Swing tutorial . There are topics on:

1. Custom painting - if you are painting your own tiles. The tutorial shows how to do custom painting on the panel

2. How to use GridLayout - if you want to add real components to the panel.

In either case the frame is just a container for the panel. All the code/logic belongs in the panel.
