Is it possible to create a wx.Notebook without the selection tabs?
I'd like to be able to manage multiple views, but with the tab selection management handled via separate buttons located elsewhere in my UI.
It doesn't seem possible since I believe that wx.Notebook uses the native Windows control. Any suggestions on how best to simulate wx.Notebook without selector tabs would be very interesting. I basically would like to be able to load arbitrary windows and panels into each tab.
Thanks

Create all the panels as you normally would for a wxNotebook, but Hide() all but one of them. When you want to switch then Hide() the current and Show() the new one, and set it's size and position as needed.

all but one of them. When you want to switch then Hide() the current
and Show() the new one, and set it's size and position as needed.
Hmm. are you suggesting that he still use a wxNotebook, but only have
one page showing at a time? In any case, you can just forget wxNotebook
altogether, and just create set of wxPanels and put them in a wxSizer,
and use wxSizer.Hide() and wxSizer.Show() as needed. I've enclosed and
example: a samll unit converter I wrote, that I emulate a Notebook in
the way discribed. I did it because only GTK provides a decent
implimentation of a notebook with the tabs on the side, rather than the
top.

No, I meant that the all the panels should be precreated just like when using a notebook, but that showing and hiding would have to be managed by his own code. (Just like you suggested, well almost.)

Nice little app. If I added an energy entry to the dictionary
would that be useful to anybody else.

Nice little app.
Thanks.
If I added an energy entry to the dictionary
would that be useful to anybody else.
Probably. If you do, please send it to me. However, I have only used
this internally, thought it could certainly enjoy a larger audience. I
wrote it for two reasons:
1) it was my first real wxPython app, and I wanted to learn and evaluate
wxPython.
2) All the unit converters I've seen either don't have the obscure units
I need, or they have absolutely everything, which gets too cluttered. My
goal was to have all the units I need, and few others.
I have had it in mind to extend it so it's easy to edit the unit
dictionary, probably putting int in a separate config file. Then
individuals could create their own unit dictionaries that met their
needs. Maybe some day.
