Just a couple of minor things which this terminal session points out


s = ttk.Style()
s.element_options('Button.label')
('-compound', '-space', '-text', '-font', '-foreground', '-underline',
'-width', '-anchor', '-justify', '-wraplength', '-embossed', '-image',
'-stipple', '-background')
s.configure('TButton', font='helvetica 24')
{}
b = ttk.Button(root)
b.configure(text='blah')



The 'element_options' call presumably shouldn't include the dashes, i.e.
'compound' rather than '-compound'

The configure call shouldn't be returning anything, akin to how configuring
a button works.

Again, just little things..

Hi Mark,

I don't think I remember very well where those element options are used.
For instance, where can you use the 'embossed' option ? Would it be only
when using style.configure/style.map with '.' as the style name ?

Knowing that would help to know if the proposed change will affect
something else (and if different/new tests should be added).

I have been working with the ttk module (Windows XP, Python 3.1) and have encountered some specific issues with ttk.Style() not fully propagating the style into the widget.  In my particular case, there seem to be issues with setting style in TCombobox and TEntry.  The biggest issue is that you can't change the style of the ttk.Combobox popdown.  Style can be set in the top window, but not using all methods, but nothing works for the popdown. 

I have included an example script that illustrates the issues I have encountered.

Is this related to the initial report ?

Setting styles may be problematic, and I don't think there is
something fully describing all the things in ttk.Style (Tcl, Python
and other languages) yet. There is a .tcl script that performs a lot
of styling here:
http://tktable.git.sourceforge.net/git/gitweb.cgi?p=tktable/tile-qt;a=tree;f=library;hb=HEAD

It might help you, but I can't confirm. Good luck, but continue this
conversation on a forum if it is not related to the initial report.

Not sure what 'embossed' has to do with not having dashes as part of the element option names.

Attached is a patch (hopefully in the right format) agains the current 3.3 sources to remove the dash from the names in .element_names(), as well as return None from .configure() when setting options.

The changes to Style.configure were not good.  Corrected so the (possibly empty) result is returned when a query is made but not when configuration is set.

Two patches: one for the element_names issue, one for the configure issue.

Question:  Does it ever make sense to do both a query and a configuration update in the same call?  I don't think it is:

--> ttk.Style.configure('TButton', 'relief', relief='sunken'
'raised'
--> s.configure('TButton','relief')
'raised'

Does it make sense to raise an exception in configure if both query_opt and kw specified?

Redid patch against current branch, fixing the typos I had in them.

Any reason not to move forward?
