Is there JFontChooser

2006-01-24, 7:58 am

I knew there are JFileChooser and JColorChooser classes
from javax.swing.*
I am looking for a class "JFontChooser" list all available
system fonts and their font sizes.

Please tell me how to get the list of system fonts.
Thank Q very much in advance!

Refer the Font2DTest demo source that comes along with the J2SDK.

You may want to see:

"It will show you what fonts are available via Java on your machine,
and what they look like in a variety of styles, sizes and colours."

Hope this helps.

I had to write one a while back. It even has a main so you can try it out.

Fonts come in all sizes in Java. See
http://mindprod.com/applets/fontshower.html
and
http://mindprod.com/applets/fontshowerawt.html

for source code to display a list of all available fonts.

A fancier version would give you a preview of what each font looked
like. That would be high overhead. You would have to load and
instantiate every font in existence. You might do that by caching an
image for each font.

By that I meant on the menu, the way MS Word does.
