After you have used exmh a little, explore
its capabilities: Click on the Preferences button.
The preferences scheme has two levels, mainly because
there are so many knobs and dials:
-
At the top level, you see a set of buttons that correspond to different modules
of the implementation.
Clicking on one of the buttons brings up the preferences items for that
module.
-
This second-level window has general information
about how the preference items affect the module.
Each preference item has its own label.
You can get more information available about each item by
clicking the first mouse button on the item's label.
The Figure below has an example.
Figure: A second-level preferences window
You can set three types of options through the
Preferences dialog:
-
Choices are represented by radio-style buttons; only one button
in the set can be enabled at once.
Changes take effect immediately.
-
Booleans are represented by check-style buttons.
A dark checkbox shows that the option is on.
Changes take effect immediately.
-
Numeric and filename settings have entry widgets in which you can
type in a new value.
Press <Return> for the change to take effect immediately (or choose
Save).
Each type of option is tied to a Tcl variable and an X resource name.
Changes in the Preference user interface change the value of the Tcl
variable, which affects the exmh runtime behavior.
To cycle through all the preference dialogs, use the
Next button.
Next takes you to the next preference
section.
The Prev button brings you back.
You should take time, at least once, to go through all the
Preference sections and get an idea of what sort of options are
available.
If you like your settings, click Save in the main
Preferences dialog.
That saves the values as X resource settings in your
~/.exmh-defaults file.
Click Reset All in the main dialog to restore all the settings
to those of your last Save.
Each module's preference dialog has a Reset
button to reset only that module's settings.
NOTE:
If you click Dismiss in the main dialog, some preferences
may have been set for the current session, but they won't
be saved to your ~/.exmh-defaults file.
