Tk Source Code

==========================================================
Hi Jeff,

I spent some of my time to contribute to the TclTk community ! I'm in
late for Christmas gift but like we said in French : "Mieux vaut tard
que jamais". ;-)

I've use TclDevKit 5.3.0 tclchecker to analyse TclTk code in Tcl and
Tk library directories (library, tools and tests) to correct a lot of
warnings and few errors. (encapsulate some expr, use 'chan xxx'
instead of fconfigure, fileevent...)

I've made some improvements too :

Examples :

- Use 'lassign' instead of many 'lindex' of 'foreach/break' loop.

- Use 'in' or 'ni' operators instead of 'lsearch -exact' or to
  factorise some eq/ne && / || tests.

- Use 'eq' or 'ne' to tests strings instead of '==' or '!='.

- Use 'unset -nocomplain' to avoid 'catch {unset...}'.

- Remove some useless catch around 'destroy' calls.

- Use expand {*} instead of 'eval'. Don't touch a lot of code because
  I don't know all structs and lists. I think it could be a greater
  improvement to reduce 'eval' calls.

Due to previous experience, I dot not change any indentation ! ;-)

purge spaces at end of lines

clean-up unix/Makefile.in after carbon removal

* generic/tkWindow.c (commands): Ensure that all descriptions of commands created by Tk are correct.

* generic/tkObj.c (GetPixelsFromObjEx): [Bug 3497848]: Better rounding of pixel values to integers.

* win/tkWinDialog.c (GetFileName): Ensure that we do not convert a result list to a string inadvertently, as this causes problems with Tkinter's handling of multiple filename results. Issue was reported via StackOverflow: http://stackoverflow.com/q/9227859/301832

• Add square to DEMOPROGS in unix/Makefile.in. It contains a shebang and hence should get installed with executable bits.

• manpages: Fix the escaping of leading dots in lines that start with a widget name, so that nroff doesn't mistake it as a non-existing macro and skips the entire line.

* generic/tkObj.c (GetPixelsFromObjEx): [Bug 3431491]: Use a bit of type hackery to allow numbers to be interpreted as coordinates (most notably on a canvas) without reinterpreting via a string.
