[Pythoncard-users] Multiple Selection List

[Michele C. <mca...@in...>]

Hi,
following the same approach of PythonCard's components, I
tried to add a multiselection list (as opposed to the single
selection one avaialable 'List') by simply copy-paste-modify
the code for List in list.py under components.  
Aside from the type field, which contains LB_MULTIPLE
instead of LB_SINGLE, a couple of changes in the getter and
setter and the class name not much was needed.
Problems arise though when I open the layout editor.  First
of all, the MultiSelList doesn't appear in the components
list.  Furthermore, when I click on List to instantiate a
new layout component, it actually instantiate a MultiSelList
instead of the usual List. I suppose there is something
going on with the registration of the class with the engine,
as the console spits an error out because the class key
lookup for MultiSelList in the component class dictionary
failed (in registry.py).

I also tried adding the new component in a another folder
appcomponents as that seems the way suggested.  No luck.

Do you have any hint on what it takes to add this new
class/component or alternatively extend the current 'List'
to be either ways (multi selection AND single selection
(default so that it does not clash with the tools already
developed)?

My Best Regards,
Thanks for this amazingly simple GUI framework.

[Pythoncard-users] tree

[John H. <ec...@ya...>]

Does anybody have more examples on the tree control?  The minimum tree only show very simple functions and I'm able to do those.  But there is no information on how I can traverse the tree - start with the root, get to the NextChild, get the label, delete a branch, programmatically expand or contract a branch, ... - all the standard things one would do with a tree...

Thanks,

My use of the tree control hasn't been much more sophisticated than the 
example. I did add a couple of extra method aliases to 
PythonCard\components\tree.py because the ones already there are only 
enough to support the example. So in __init__ I added

setExpanded = wx.TreeCtrl.Expand
clearTree = wx.TreeCtrl.DeleteAllItems

so that having built the tree from a dictionary I could open up all of 
the nodes at startup, and I could tear it down and rebuild it 
differently later on.

With the help of a debugger and plenty of Google searches, and a lot of guessing, I was able to invoke most of the wx tree functions.  It proves that the minimal tree wrapper does work.
