I have a specific question - how can I generalize a
FileBrowseButtonWithHistory - and I realized, as I was trying to word my
question, that my real question is a bit more generic.
First, the specific question: The FileBrowseButtonWithHistory requires a
callback override and some custom code to straighten out handling the
history. So far, so good. However, I wish to use more than one FBBWH on my
form, and I can't figure out how to re-use the custom callback so it will
work for both controls. (It makes me sick to my stomach when I look at my
code and see duplicate blocks!) Don't get me wrong - it's working right
now, it's just that my code is fugly and I want to clean it up.
In more general terms, how can I set more than one control to use the same
block of code as a custom callback, and figure out at runtime which control
I'm responding to? Doesn't the Event or CommandEvent carry any information
about itself?
I've tried this:
[snip]
self.fp1 = filebrowse.FileBrowseButtonWithHistory(pnl, -1,
size=(300, -1),
labelText='', fileMask='*.*', fileMode=wx.OPEN,
dialogTitle='Select the file containing UCF claims',
changeCallback=self.fp1Callback)
self.fp2 = filebrowse.FileBrowseButtonWithHistory(pnl, -1,
size=(300, -1),
labelText='', fileMask='FI*.*', fileMode=wx.OPEN,
dialogTitle='Select the form-image file - generally starts with
FI', changeCallback=self.fp2Callback)
[snip]
def fp1Callback(self, evt):
print evt.__dict__
print help(evt)
value = evt.GetString()
[snip]
def fp2Callback(self, evt):
print evt.__dict__
print help(evt)
value = evt.GetString()
[snip]
All I get from "print evt.__dict__" is: {'_string':
u'E:\\ultrahld\\report\\FILE'}
and all I get from help is:
Help on instance of LocalEvent in module
wx.lib.filebrowsebuttonobject:class instance(object)
| instance(class[, dict])
|
| Create an instance without calling its __init__() method.
| The class must be a classic class.
| If present, dict must be a dictionary or None.
|
| Methods defined here:
|
| __abs__(...)
| x.__abs__() <==> abs(x)
|
... in other words, I might as well have typed "help(object)".
I only know that the method "evt.GetString()" exists because the example in
the demo uses it.
I've Googled, and Gmaned, and read the wx docs (such as they are), but I'm
not seeing anything I can use.
I know that this is a wxPython question, and that this is the Python list...
but y'all have answered some wx questions in the past, and I hate to join
another list for one question. If I must, I will... but thanks in advance
for any light you can shed.
