QTriplot can be controlled by the menus as well as by entering commands though the keyboard.
You may bring up the command window by pressing Esc. By pressing Esc again, you may hide the command window again. You don't need to activate the command window to enter commands; the commands are accepted whether the command window is visible or not.
A triangulated object is added to the display by entering the command "file name=filename", where filename is the name of a file describing a triangulated object, and name is the name by which this name will be known internally in QTriplot. "file filename" is shorthand for "file filename=filename".
Throughout this manual, text you are supposed to type into the command window,
is displayed in courier. The names of commands are displayed in
bold, and text that has to be replaced by something else
(e.g. the name of an object, or the value of a parameter) is displayed
in italic.
If a string can be ommitted, it is placed between square brackets [].
If there is a choice between two or more strings, the strings are separated by
a vertical line |, like in "yes|no".
"parameter value" sets the parameter for the active object, i.e. the object that was loaded most recently.
"parameter *=value" sets the parameter for the all objects.
"parameter !=value" sets the default value of the parameter, i.e. the value that will be given to that parameter for objects that are loaded henceforward.
If is does not compromize the uniqueness of the command, you may abbreviate a command to its first 3 or 4 characters.
The section commands provides a list of all commands and explanation of their function.
If you enter a command that is not known internally, Qtriplot will try to open the file command.trp, and, if successfull, will read commands from that file. Commands files can be nested.
Some aspects of the display are controlled by mouse actions and keyboard accelerators. Finally, you can set a number of options in the command line.
