I'm not sure where the documentation is, but tk.call is a raw Tcl
command being invoked from Python without being wrapped by Python
classes/methods. For instance:
self.tk.call('package', 'require', 'tile')
is equivalent to this call in a Tcl script:
package require tile
Generally I use tk.call if I have to get "close to the metal" in dealing
with Tk. Tkinter does a good job of abstracting this, but, as you no
doubt know, Tkinter.py itself is full of 'tk.call' code, i.e.:
def wait_visibility(self, window=None):
"""Wait until the visibility of a WIDGET changes
(e.g. it appears).
If no parameter is given self is used."""
if window is None:
window = self
self.tk.call('tkwait', 'visibility', window._w)
def setvar(self, name='PY_VAR', value='1'):
"""Set Tcl variable NAME to VALUE."""
self.tk.setvar(name, value)
def getvar(self, name='PY_VAR'):
"""Return value of Tcl variable NAME."""
return self.tk.getvar(name)
and so on. There's simply no other way to get at the guts of Tk without
using tk.call at some level.
