Auto completion list is invisible in some situations
« on: May 21, 2014, 03:44:55 pm »
Very annoying issue if I'm typing at the bottom of the editor window and the Logs'n'others is hidden.

Steps to reproduce:
1. Maximize C::B
2. Hide Logs'n'others
3. Open a text file that can fill the full screen
4. Go to the last line
5. Show the autocompletion list

The result is that the autocompletion list is displayed below my cursor and it is almost fully invisible.

This is caused by a screen vs. client coordinate issue.  The following patches this (but might break other assumptions? ... needs more testing).
Code

        } else {

@devs: From what I can tell, Window::GetPosition() currently has an incorrect implementation, and will (always?) return top left corner as (0, 0).  Thoughts?

Probably you should ask in the wx-dev mailing list, there you'll get better advice, also you can contribute this patch to the wx project.

Fixed in rev 11360...
The call tip has also been affected by this problem.
