更改Java JFrame的图块

Question

I'm wondering, how can I set the title of my Java JFrame GUI to something different later on? My program is a basic text editor, and I want to change the title to whatever you just saved your file as, or New File if you hit the New File button, or you just started the application up. The method I'm using right now is just a simple setName("" + file + ""); where file is the File that was just written or read.

Answer 1

setTitle是您需要的，而不是setName。

Answer 2

您可以使用Frame＃setTitle（String）设置JFrame的标题。

yourJFrame.setTitle("words.txt");
