SetFocus problem (Patricio Stegmann)

wxPython Users
1

I created a simpler example you can test.
The SetFocus is being called, but is not focusing the element.
See the example in this url:

http://pastebin.com/f3a4d2ef6

or in the following code:

import wx
from wx import xrc
import thread
import time

g__gui_xrc = ‘’‘<?xml version="1.0" encoding="utf-8"?>


Primary Frame
100,100


2
1
0
0



1
wxEXPAND
5

bt1



1
wxEXPAND
5

bt2





’‘’

def do_some_calculation(i__obj=None):
print ‘calculating something …’
time.sleep(3)
print ‘done, now gotresult’
i__obj()

class GuiApp(wx.App):
def OnInit(self):
self.m__timer = None
self.m__cnt = 0
self.m__buttons = [‘m__button_one’,‘m__button_two’]
self.m__xrc_ressource = xrc.EmptyXmlResource()
self.m__xrc_ressource.LoadFromString(g__gui_xrc)
self.m__capture_frame = self.m__xrc_ressource.LoadFrame(None, ‘mainFrame’)
self.m__main_panel = xrc.XRCCTRL(self.m__capture_frame, ‘mainPanel’)
self.m__button_one = xrc.XRCCTRL(self.m__capture_frame, ‘button_one’)
self.m__button_two = xrc.XRCCTRL(self.m__capture_frame, ‘button_two’)
self.m__capture_frame.Bind(wx.EVT_BUTTON, self.buttonClick, self.m__button_one)
self.m__capture_frame.Bind(wx.EVT_BUTTON, self.buttonClick, self.m__button_two)
self.m__capture_frame.Show()
return True

def buttonClick(self, i__event=None):
    thread.start_new_thread(do_some_calculation, (self.gotResult,))

def gotResult(self):
    print 'gotResult'
    self.m__cnt += 1
    l__button_name = self.m__buttons[self.m__cnt%2]
    print 'giving focus to ',l__button_name
    l__obj = getattr(self, l__button_name)
    l__obj.SetFocus()

if name == ‘main’:
g__app = GuiApp(0)
g__app.MainLoop()

Please let me know if I am doing something wrong. I am using wxPython 2.8.9 and python 2.5.1 on windows xp.

I would have expected that 2.8 would be the default, but of course
this is debatable. Is this intended behaviour? Is there a way to set
system wide the preference for 2.8 instead of 2.6? Robin, does Ubuntu
implement this differently from upstream wxpython?
This used to work as expected in Ubuntu < 9.04…

Under Jaunty things are different, because every wxpython package adds a
wx-2.[68]-gtk2-unicode.pth to /usr/lib/python2.6/dist-packages, so - if I
understand it correctly - on a “import wx” Python chooses alphabetically,
thus the 2.6 version…

I worked around it by removing those .pth’s and keeping a simple wx.pth
containing “wx-2.8-gtk2-unicode”.

I don’t know if there’s an “official” way of doing it :slight_smile:

You’re supposed to be able to use update-alternatives to switch between
which wx.pth file is installed in [site|dist]-packages, but if Ubuntu has
changed how that file is installed and managed then that feature is probably
broken.
Could you give the full command? I don’t know the argument, eg it is
clearly not:
sudo update-alternatives python-wxgtk

It should be something like:

sudo update-alternatives --set NAME DEST

Where NAME is some link in /etc/alternatives (used to be just wx.pth,
but now I think it is something like wx$PYVER.pth) and DEST is the file
that it should be linked to. My packages install the DEST files in
/usr/lib/wx/python$PYVER/wx$WXVER.pth. I’m not sure if the Ubuntu
packages follow the same pattern any more, or even if they are still
using update-alternatives for that .pth file. (And I don’t have an
untweaked Ubuntu box handy to check.)

Hello to all,

I am having a problem on the SetFocus method of an element. =

Basically the wxApp receives an external call for it to focus a particular =
button on the frame’s gui.
However the Focus is not being passed even if the element ‘AcceptsFocus’.

I have here an example: the application is run and a webservice talks to it=
. This webservice allows, via a client, to set the Focus on a particular bu=
tton. However nothing happens.
I am trying to solve this issue and cant figure out what is going on. I alr=
eady tried asking on IRC etc… but nobody helps me !

Please check here the webservice server code:

server.py

import SOAPpy
import wx
from wx import xrc

Well, very strange, if I do:
$ ls /etc/alternatives | grep wx
wx2.5.pth
wx2.6.pth

$ sudo update-alternatives --config wx2.6.pth
[sudo] password for stani:

Er zijn 2 alternatieven die ‘wx2.6.pth’ voorzien.

Selectie Alternatieven

*+ 1 /usr/lib/wx/python/wx2.8.pth
2 /usr/lib/wx/python/wx2.6.pth

It shows that 2.8 is already the default for wx2.6.pth

I noticed a bug, that in sys.path both 2.6 and 2.8 were present, so I
reported it here:
Bug #379573 “sudo update-alternatives does not configure the def...” : Bugs : wxwidgets2.8 package : Ubuntu

Hi,

I have a mediactrl instance that has a video file playing. I want to be
able to show the same video on another frame simutaneously, is it
possible?
