The following source code shows how to set the font, caret position, and margins on a JTextArea
component:
JTextArea textArea = new JTextArea(); // somewhere later in your code ... textArea.setFont(new Font("Monaco", Font.PLAIN, 12)); textArea.setMargin(new Insets(12, 12, 12, 12)); textArea.setCaretPosition(0);
The Font and margin/insets probably make sense in terms of what they do.
The reason I set the caret position at position zero is in case the textarea gets filled with a lot of content; in that situation it will scroll the textarea to the bottom, and setting the caret position at 0 makes sure the beginning of the text is shown at the beginning of the JTextArea
. One note about this: you probably have to set that caret position after you set the actual text (String
) in the textarea. It’s been a while since I wrote this, but I think that’s true.
