All messages from Ghostscript are stored in a log dialog.
By default this dialog is not visible but may be viewed at any time using
the Hide Log entry in the
Window Menu.
The
hideLog application resource may be
used to alter the default behavior for all instances of MGv and the
-log and -nolog command-line switches (see
Command Line Switches) may be used to alter the default behavior
for a single execution. The message log is also used to display errors
from the Ghostscript interpreter. If there is an error, the log will
automatically pop up.
The log dialog consists of the following widgets:
- A Scrolled text region for displaying the messages. The text widget
is editable so you are free to add notes if you find a bug in
MGv, Ghostscript, or someone's PostScript program.
- A Hide button for popping down the log until an error occurs or
you explicitly request its presence again.
- A Save button for saving the current contents of the log to
a file. This button will activate a standard file selector to ask
for the filename.
- A Clear button for emptying the log.
- A Help button for requesting help on the log dialog.
