With the gradual development, I found that I did not understand anything, And suddenly lost my sense of superiority. Originally, what programmers want to do with this kind of superiority will only let you go downhill, continue to learn and understand and try again to survive. Let's go back to the basics.

The object that produces the event, puts the event information. A way to pass to listeners for processing. The event infor

1. Structural Partitioning There are two types of Swing components, one is the JComponent class and one is the Windows class. Where the Windows class contains components that can be displayed independently, and the JComponent class contains components that cannot be displayed independently .

A lot of things are the meaning of the original article only after reading the program. This is an episode and is not within the scope of mapseditor. By the way, three to four people joined the group at noon, which was quite fun. Even if you are a beginner, it is important for you to co
