Key macro <B>:</B> (colon) implements the command <I>tk_path_name</I>
|

|

by prepending the window name to the command typed on the command

line when the command is executed. This action is, however,
|

|

transparent to the end user.

<H3>Summary:</H3>
|
||
|
|
<BLOCKQUOTE>
|
||
|
|
The <I>tk_path_name</I> command is unique for each window
|
||
|
|
that is created in magic. The name of the window is
|
||
|
|
registered as a command name with the Tcl interpreter.
|
||
|
|
When the window name is used as a command, the arguments
|
||
|
|
of the command are passed to the <B>magic</B> command
|
||
|
|
interpreter to be executed in the context of that
|
||
|
|
specific window. Effectively, it is the same as typing
|
||
|
|
the macro "<B>:</B>" (colon) in a layout window, and then
|
||
|
|
typing the command on the command line. <P>
|
||
|
|
|
||
|
|
For example, the default first window that is created in
|
||
|
|
the Tcl GUI version of magic is <B>.layout1.magic</B>.
|
||
|
|
Upon creation, the command name <B>.layout1.magic</B> is
|
||
|
|
registered with the Tcl interpreter. Subsequently, any
|
||
|
|
command on the command-line will be executed in relation
|
||
|
|
to that window if it is specified as an option to the
|
||
|
|
<B>.layout1.magic</B> command:
|
||
|
|
<BLOCKQUOTE>
|
||
|
|
<B>.layout1.magic box 0 0 10 10</B>
|
||
|
|
</BLOCKQUOTE>
|
||
|
|
which is exactly the same as putting the X11 pointer
|
||
|
|
cursor in the layout window, typing the "<B>:</B>"
|
||
|
|
(colon) macro, then typing the command <B>box 0 0 10 10</B>
|
||
|
|
into the command line and hitting the <B>return</B> key. <P>
|
||
|
|
|
||
|
|
Similarly to layout windows, windows created with the
|
||
|
|
<B>specialopen</B> command have their Tk path names registered
|
||
|
|
as commands with the Tcl interpreter, and can be passed
|
||
|
|
commands recognized by the specific window type (e.g.,
|
||
|
|
netlist commands in the netlist special window).

<H3>Implementation Notes:</H3>
|
||
|
|
<BLOCKQUOTE>
|
||
|
|
<I>tk_path_name</I> is implemented as a built-in command
|
||
|
|
in <B>magic</B> which is registered with the Tcl interpreter
|
||
|
|
when the window is created and unregistered when the
|
||
|
|
window is destroyed.
