Hi list,
I have two questions about ListCtrl. I create a small app that show db
data into a ListCtrl.

1) When I scroll data with the key (UP, DWN), sometime I receive an error:

wx.ListCtrl.Refre****ems(self, start, stop)
File
"/",
line 4463, in Refre****ems
return (*args, **kwargs)
wx._core.PyAssertionError: C++ assertion "lineFrom <= lineTo" failed at
/src/generic/listctrl.cpp(2498) in RefreshLines(): indices in disorder

What can be?

First, why do you call wx.ListCtrl.Refre****ems(self, start, stop)
instead of self.Refre****ems(start, stop)? Second, is start stop?

2) win the "return", "space", "escape", etc keys (so the function
keys) are passed to the ListCtrl Char event, but on lin not. Is there
a solution for say to wx to pass them (generate an event) on these keys?

What is meant by "on lin" ? Whatever it is you can probably get it by
using a EVT_KEY_DWN handler.

After you create your frame, try something like

myframe.Raise()

To bring it to the top.

This might be an obvious thing I am missing, but I can't figure out
how to being a wx.Frame to the front. Normally, frames are
automatically created on top of all the others, but for some reason
since I am creating this frame after the user double clicks on a
ListCtrl item (an EVT_LIST_ITEM_ACTIVATED event) that form stays on
top with focus, as if the second click brings it forward. If use
enter to select the item instead, the frame pops up in front like
normal.

Robin mentioned once in a post you can get the top window by caling
wx.GetActiveWindow(). I tried wx.SetActiveWindow(), but that method
doesn't exist :(

Any ideas will be much appreciated.

Thanks, I did try that, and unfortunately didn't help. I've tried
calling Raise at various times (as late as possible after the form is
created, in the __init__ method for the form etc.) but no luck. I've
tried calling Lower on the frame that's stubbornly staying on top,
but that's not helping neither.

Try delaying the creation of the 2nd frame until all of the events
associated with the double click have time to complete.

How would I do this?

The same as any other delayed effect in wxPython. Move the code that
creates the new frame into another function, and then invoke that
function via either wx.CallAfter or wx.FutureCall.
