How to add text to JFrame?(如何将文本添加到 JFrame?)
问题描述
So I am designing a JFrame using Eclipse WindowBuilder. This specific frame is an error message stating that the user provided invalid credentials. I have added a button to exit the frame and I now need to display the actual error message "The login credentials specified are invalid. Please provide valid credentials."
I have done some searching and everyone says to use a JLabel, but when I create my JLabel and enter the text to it, there is no wordwrap or anything so I can't fit the label inside my frame.
What is an easy way to simply display a message in the center of the JFrame?
To create a label for text:
JLabel label1 = new JLabel("Test");
To change the text in the label:
label1.setText("Label Text");
And finally to clear the label:
label1.setText("");
And all you have to do is place the label in your layout, or whatever layout system you are using, and then just add it to the JFrame...
