Re: [Boa Constr] New version in CVS

[Christian T. <ti...@ti...>]

Hi Riaan,

many many thanks for the good explanation.
This has helped me very much. Understanding
large code bases is not easy without an overview.

Also many thanks for the slider example.

Yes, I understand.
While I found it handy to have some stuff which is
available both at design- and run-time in Delphi.
Maybe some methods could be published with some
_desidng_time_methods = {...} thingy, but this is minor.

Yes, unless you tell it to get a label which tells the current
position. Boy then still thinks to know where the boundaries
are, but the control believes it starts with the label,
and positioning becomes impossible.

On events: I tested the sliderevent it doesn't respond.
Basically, it looks like a mistake in wxWindows to let
it support it, since the docs say sliderevents are obsolete.
Therefore, I'd remove the entry from Boa.

Tickfreq is another one, I think I found a note in the
source that this isn't handled correctly yet.

Yes, I know that. Same with tabbed notebooks. I'd love to
tech them tabbing in the IDE, since that would make it
considerable to put objects on them.
Actually, access is too slow for me, and I use a couple of
dummy wxFrames for my pages, and dynamically reparent them
into my notebook container.
I do this in many window contexts, since I'd like to
mimick what Delphi does with its frames and subframes.

Yes, I found a comment like "what is the second parameter for"
in the wxWindow docs. I guess this was meant to be the starting
value where ticks should be generated?

Will look into this, soon.

Thanks again!

[companion file size]

Looks like a good solution.
This would make it much simpler to look up a definition.
It took a lot of time until I understood where the labels in the
Palette come from, and the icons (since the latter are computed
names, tricky :-)


Thanks so far, I will become a real Boa (ab)user.

*) deriving from a wxStaticBitmap works fine, but for some
reason, I cannot avoid to produce a memory leak a wxBitmap
of size 12 is always left over, even if I do no more than

class MySpecialBitmap(wxStaticBitmap):
     def __init__(self, *args, **kwds):
         wxStaticBitmap.__init__(self, *args, **kwds)

But this is probably a question for Robin :-)
