Tixwish is a simple program consisting of the Tcl command language, the Tk toolkit, and a main program that reads commands from standard input or from a file. It creates a main window and then processes Tcl commands. If tixwish is invoked with no arguments, or with a first interactively from standard input. It will continue processing commands until all windows have been deleted or until end-of-file is reached on standard input. If there exists a file .tixwishrc in the home directory of the user, tixwish evaluates the file as a Tcl script just before reading the first command from standard input.
If tixwish is invoked with an initial fileName argument, then fileName is treated as the name of a script file. Tixwish will evaluate the script in fileName (which presumably creates a user interface), then it will respond to events until all windows have been deleted. Commands will not be read from standard input. There is no automatic evaluation of .tixwishrc in this case, but the script file can always source it if desired.
Tixwish automatically processes all of the command-line options described in the OPTIONS summary above. Any other command-line arguments besides these are passed through to the application using the argc and argv variables described later.
The name of the application, which is used for purposes such as send commands, is taken from the -name option, if it is specified; otherwise it is taken from fileName, if it is specified, or from the command name by which character, then only the characters after the last slash are used as the application name.
The class of the application, which is used for purposes such as specifying options with a RESOURCE_MANAGER property or .Xdefaults file, is the same as its name except that the first letter is capitalized.
Tixwish sets the following Tcl variables:
Name: tixScheme
Class: TixScheme
Name: tixFontSet
Class: TixFontSet
For example, you may put these two lines in your .Xdefaults file
*tixwish.tixScheme: Gray
*tixwish.tixFontSet: 12Point
If you create a Tcl script in a file whose first line is
#!/usr/local/bin/tixwishthen you can invoke the script file directly from your shell if you mark it as executable. This assumes that tixwish has been Many UNIX systems do not allow the #! line to exceed about 30 characters in length, so be sure that the tixwish executable can be accessed with a short file name.
When tixwish is invoked interactively it normally prompts for each variables tcl_prompt1 and tcl_prompt2. If variable tcl_prompt1 exists then it must consist of a Tcl script to output a prompt; instead of outputting a prompt tixwish will evaluate the script in tcl_prompt1. The variable tcl_prompt2 is used in a similar way when a newline is typed but then no prompt is output for incomplete commands.
