Specifies that the window should have a new private colormap instead of using the default colormap for the screen.
Display (and screen) on which to display window.
Initial geometry to use for window. If this option is specified, its value is stored in the geometry global variable of the application's Tcl interpreter.
-name name Use name as the title to be displayed in the window, and as the name of the interpreter for send commands.
-sync Execute all X server commands synchronously, so that errors are reported immediately. This will result in much slower execution, but it is useful for debugging.
-use id Specifies that the main window for the application is to be embedded in the window whose identifier is id, instead of being created as an independent toplevel window. Id must be specified in the same way as the value for the -use option for toplevel widgets (i.e. it has a form like that returned by the
winfo id command).
Wish 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 wish is invoked with no arguments, or with a first argument that starts with ``-'', then it reads Tcl commands 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 .wishrc in the home directory of the user, wish evaluates the file as a Tcl script just before reading the first command from standard input.
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 wish was invoked. In the last two cases, if the name contains a ``/'' character, then only the characters after the last slash are used as the application name.
Wish sets the following Tcl variables:
argc Contains a count of the number of arg arguments (0 if none), not including the options described above.
argv Contains a Tcl list whose elements are the arg arguments that follow a -- option or don't match any of the options described in OPTIONS above, in order, or an empty string if there are no such arguments.
argv0 Contains fileName if it was specified. Otherwise, contains the name by which wish was invoked.
If the -geometry option is specified, wish copies its value into this variable. If the variable still exists after fileName has been evaluated, wish uses the value of the variable in a wm geometry command to set the main window's geometry.
If you create a Tcl script in a file whose first line is
then you can invoke the script file directly from your shell if you mark it as executable. This assumes that wish has been installed in the default location in /usr/local/bin; if it's installed somewhere else then you'll have to modify the above line to match. Many UNIX systems do not allow the #! line to exceed about 30 characters in length, so be sure that the wish executable can be accessed with a short file name.
An even better approach is to start your script files with the following three lines:
exec wish __
