Toolbar button alpha channel problem in matplotlib
Werner F. Bruhin
not usable at the time.
Doing this shows a black square instead of applying the alpha channel
(correct terminology?).
To ensure that the icon file actually is o.k. I created a toolbar with
the icon in question and it shows correctly as a black and white version
when it is in-active and a colored version when it is active.
Matplotlib uses "AddSimpleTool" to create the tools, so I tried
"AddLabelTool" and "DoAddTool". With the later two calls the image is
now in color if active or in-active - still not showing the black and
white version.
Here some code snippets:
self.AddLabelTool(label = 'Back',
bitmap = _load_bitmap2('back.png'),
bmpDisabled = wx.NullBitmap,
id = self._NTB2_BACK,
longHelp = '',
shortHelp = '')
_load_bitmap2 is just checking that the image exists and returns a
wx.Bitmap instance.
The attached "toolbartest.png" shows what we like to see and the
"matplottoolbar.png" shows the back button in color using the
"AddLabelTool" and the grey square is for the forward button which uses
"AddSimpleTool".
Any hints on how to fix this would be very welcome.
See you

Both AddSimpleTool and AddLabelTool call DoAddTool, so there must be
some other difference between the two cases. What is the platform and
version? Can you send a small sample (including the images) that shows
the problem?

The mystery of the color or grey square button is me forgetting what I
am doing!
The grey square is the due to matplotlib using "xpm" file format and
wxPython only supports alpha channel with "png" file format, according
to the documentation.
However I still can't figure out why the color version is shown (when
using "png" files) when the tool button is disabled, it should show the
grey & white version.
Had no success in creating a small test program showing the problem,
will have another go at it next week.
See you

Hehehehehehe... it is normal, everywhere I go people keep saying "from your
name I was expecting a woman..."
No rpoblem for that ;-)
However, when I posted my first controls (like FoldPanelBar, HyperLinkCtrl,
ExtendedChoice and so on), I was somehow impressed by the number of nice
replies/comments I got. Did the "he/she" confusion influenced your suggestions/comments?
;-)))))

Hello Andrea,
in your first posts, I wasn't really sure.
You could be a "she" or "he", but that should make no difference.
At the same time I remembered a former Formula One driver
"Andrea de Cesaris".
In german "Andrea" is a woman forename (not sure, how it is in english)
in oppostition to Andreas.
But more often, woman forenames are longer than the man counterparts.
man -> woman
Franz -> Franziska
Martin -> Martina
Stefan -> Stefanie
Daniel -> Daniela

Being Swiss I should not have missed that one :-[ , hope you'll forgive me!
Coming back to this toolbar issue, created a small test program to try
to imitate the stuff matplotlib does with the toolbar but on my system
(XP) it works like a charm, but within matplotlib I still get this damn
grey squares.
It is obviously way above my head!
See you

well to make the subject complete you should have posted
this:

or this...

now let's face it... we all like Andrea for the widgets he brought to
wxPython... but... it wouldn't have hurt to look a little bit like this:

Andrea stems from greek meaning 'man' ...
Being a German myself, I wonder what language got confused ;)
But seriously,
with me affection only has me for the nice controls you have posted.
Keep hanging in there! I really like them a lot!

Wow... what a nice programmer this chick ;-)
No luck for me, I have never met a Linux/Windows/Unix/Mac/Debian/Whatever
programmer like that... mhm, do I have to switch to another GUI tool to
find her? ;-)

XPM files do support a mask, or in other words a 1-bit alpha where each
pixel is either fully transparent or fully opaque, (so there is no
blending.)

That I don't know...

Hello Peter,
thank you for this interesting site.
For me applies:
"
German form of Franciscus (see FRANCIS). This name was borne by the influential author Franz Kafka, writer of 'The Trial' and 'The
Castle' among other works.
Also, rulers of Austria and the Holy Roman Empire have had this name.
"
Wow, what honour ;)
