Unable to scroll map selection dropdown lists with mouse scroller

[marisn]

Any map choice drop-down list with scrollbars is unscrollable with mouse scroller. User has to click on up/down or drag slider but can't use mouse scroller. Also it's impossible to use keyboard up/down arrows or PgUp/PgDown to scroll that list.

Same issue applies to gis.m

Windows Vista running WinGRASS-6.4.SVN-r41233-1

Still an issue for WinGRASS-6.4.SVN-r45559-1

mouse wheel, up-down, pgup-pgdown, and home-end keys all work for me in linux. (new debian stable+xfce4+wx 2.8.10.1) the only thing I tried that doesn't work there is typing the first letter when scrolling through the list to jump to the next map starting with that letter.

does it help to click on a map name first? (force context change to the list)

I assume this needs to be fixed at a lower wxPy<-->Windows desktop level, and there's probably not much we can do about it.

can you find another wxPy app on Windows and see if it behaves the same way? (eg Audacity??)

ps- please use the "wingrass" keyword for ms-windows problems so it gets picked up on the list of open Windows bugs. see ​http://trac.osgeo.org/grass/report # 14

Tested again with winGRASS 6.4.svn (r55719).

Works:

• (long) map list can be scrolled by mouse using slider
• (long) map list can be scrolled by mouse clicking up/down slider arrows

Fails/unsupported:

• use mouse wheel (API: ​http://wxpython.org/docs/api/wx.MouseEvent-class.html)
• use keyboard up/down arrows (maybe key binding missing?)
• use keyboard page up/down (maybe key binding missing?)

The mouse wheel support would be a great nice-to-have.

I already spent some time with this widget but without any results. It has apparently some problems with focus and events (on all platforms). I've just tested this widget with wxPython 2.9.5 in the wxPython demo and it seems to be fixed at least for Linux (Ubuntu).

no, it's not, just the widget has many different bugs under different systems. I am afraid this won't be fixed for grass 6.

Seems to be fixed at some point. Issue is absent on Windows 10 - mouse scroller works as expected. Keyboard navigation still is not working but it is not so crucial. Closing this issue as fixed.
