[java] identifier expected - Tilted Forum Project Discussion Community

zharvey · 02-23-2006, 03:13 PM

I am trying to change the default behavior of a JTextArea. I want to change the font, the font flags, and the font size of the text entered into the area. Here is my code in its amazing entirety:

Code:

JTextArea canvas = new JTextArea(30,70);
canvas.setFont(new Font("Arial", Font.BOLD | Font.ITALIC, 20));

I am getting a compiler error specifying "identifier expected" for the 2nd line. It is complaining about the call to setFont(), which is a method inherited from Component. I posted this on a programming-oriented forum on another site and everyone is baffled and says my code should be fine. I am using JDK5 and compiling using javac.

I am thinking that perhaps I have an error elsewhere (and above) in my code and that perhaps it is cascading down to this function call....

The weird thing is if I comment out the 2nd line and replace it with:

Locale l = canvas.getLocale();

it works fine. In other words, it handles other Component methods perfectly fine, which tells me it doesn't like my call to setFont. I checked the method's definition out in the java docs and according to Sun, the signature for setFont() is this:

public void setFont(Font f)

So I don't see what I am missing here...

It certainly seems about right to me....don't see anything wrong with it...

maybe you could post some more of the code preceeding it?

Maybe too obvious, but did you import java.awt.Font?

Change it to

Code:

java.awt.Font f = new java.awt.Font("Arial", java.awt.Font.BOLD | java.awt.Font.ITALIC, 20);
JTextArea canvas = new JTextArea(30,70);
canvas.setFont(f);

and see if it complains about the first line.

Yeah I imported Font from the AWT. Actually a poster on another website suggested that its a cascading error from previous code. But that makes no sense because replacing it with a call to any other Component-inherited method works perfectly fine.

It either doesn't like setFont() or the argument I am passing it....which makes no sense again because I am using the correct signature....oy vey.

Use a canvas.setFont(null) .. what's it throw then? Same thing?
