Fonts
This module is designed to allow you to easily select different fonts for different parts of the Desktop.
The panel consists of different font groups to give you a lot of flexibility in configuring your fonts:
General (Used everywhere the other font groups don't apply)
Fixed width (Anywhere a non-proportional font is specified)
File Manager (Font to use in the file manager)
Toolbar (Font used in application toolbars)
Menu (Font used in application menus)
Window Title (Font used in the window title)
Taskbar (Font used in the taskbar panel applet).
Each font has a corresponding Choose... button. By clicking on this button, a dialog box appears. You can use this dialog box to choose a new font, font style, size and character set. Then press OK.
An example of the font you have chosen will be displayed in the space between the font group name and the choose button.
When you are done, simply click OK, and all necessary components of will be restarted so your changes can take affect immediatly.
Finally, there is a check box to enable Anti Aliasing for fonts. The ability to use Anti Aliased fonts and icons requires that you have support in both X and the toolkit, and that you have suitable fonts installed, and are using the built in font serving capabilities of the X server. If you still are having problems, please contact the appropriate mailing list, or check the FAQ.
The Adjust All Fonts... allows you to quickly set a property or set of properties of all the fonts selected above. A font selection dialog similar to the standard one will appear, but you will notice checkboxes that allow you to change the Font, Font style or Size independently of each other. You can choose any one, two, or three of these options, and they will be applied to all the font groups.
For example, if you have selected several different font faces above, and realize they are all a size too big (this often happens when you change screen resolution, for instance), you can apply a new font size to all the fonts, without affecting your customized font faces and styles.
