Problems with current value of wx.SpinCtrl and EVT_SPIN

2006-04-09 Thread blackno666 
Hello,

I am new to Python/wxPython and am experiencing first problems. I have
a dialog which includes a SpinCtrl and a Slider. I want the Slider to
affect the SpinCtrl and vice versa
(http://wiki.wxpython.org/index.cgi/ChallengeDemos#Part1).

The code I wrote does, however, not work correctly. The event EVT_SPIN
is never handled (even though I wrote a handler), and in the handler of
EVT_SCROLL_CHANGED I do not obtain the modified value, but the value
before the control has changed.

Any feedback would be greatly appreciated.
To clarify my problem, here's the code (Python2.4, wxPython 2.6) :

import wx

class AppFrame(wx.Frame):
def OnSpinGeneral(self, event):
b = wx.MessageBox("never reached")

def OnSpin(self, event):
# I tried to use Skip so that the changing of the value would
take place before
# I invoke GetValue(), however this has no effect
event.Skip()

print self.spin.GetValue()
self.slider.SetValue(self.spin.GetValue())

def OnScrollChanged(self, event):
self.spin.SetValue(self.slider.GetValue())

def __init__(self):
wx.Frame.__init__( self,
  None, -1, "",
  #size=FRAME_SIZE,
  style=wx.DEFAULT_FRAME_STYLE )
self.sizer = wx.BoxSizer( wx.VERTICAL )



self.spin = wx.SpinCtrl(self, min = 0, max = 50)
self.slider = wx.Slider(self, 1, 6, 0, 50)

self.sizer.Add(self.spin)
self.sizer.Add(self.slider)

self.Bind(wx.EVT_SCROLL_CHANGED, self.OnScrollChanged,
self.slider)
self.Bind(wx.EVT_SPIN_UP, self.OnSpin, self.spin)
self.Bind(wx.EVT_SPIN_DOWN, self.OnSpin, self.spin)
self.Bind(wx.EVT_SPIN, self.OnSpinGeneral, self.spin)

self.SetSizer(self.sizer)
self.SetAutoLayout(1)
self.Show(1)

app = wx.PySimpleApp()
frame = AppFrame()
app.MainLoop()

Re: wxStyledTextCtrl - Dead?

2006-04-09 Thread blackno666 
The wxPython Demo
(http://prdownloads.sourceforge.net/wxpython/wxPython-demo-2.6.3.2.tar.gz)
still contains the wxStyledTextCtrl:

wx.stc.StyledTextCtrl

The demo is probably also a good example of how to use
wxStyledTextCtrl.

Basic information can be found on
http://www.yellowbrain.com/stc/init_repr.html

Regards.

Yes, it "works". However buggy.

When the slider is set to 0 and the up button is pressed in the
SpinCtrl, the value in the SpinCtrl will be 1, but the slider will not
move. There's also a discrepancy between the value displayed in the
SpinCtrl and the value output by

print self.spin.GetValue().

When playing with this code I also noticed that I was not able change
the behaviour of the up and down buttons. I expected that if I modify
OnSpin in the following way:

def OnSpin(self, event):
pass

That pressing the spin buttons would have no effect. However, the value
is still increased or decreased

Just found a solution to the problem:

when using wx.EVT_SPINCTRL instead of wx.EVT_SPIN_UP, wx.EVT_SPIN_DOWN
or wx.EVT_SPIN the program behaves correctly.

wxWidget documentation for wxSpinCtrl states that "You may also use the
wxSpinButton event macros, however the corresponding events will not be
generated under all platforms"; I ran the program on WinXP SP2.
However, the events seem to be handled (at least EVT_SPIN_UP,
wx.EVT_SPIN_DOWN). So I do not understand why handling these events
leads to a buggy behaviour.
