Hello
I am new to PyQT and would appreciate help with the following problem.
I have a database table that has, amongst other fields, a nullable
date - EndDate. On my form I have a QDateEdit widget which I only want
to show a value if the date is not null, a user will enter a date once
there is one
I've played with signals and slots in PyQt about 2 month ago and came to
this:
- Qt signals added to Qt classes with names as in qt, implemented using
__get__ protocol,
so calls like connect(w.signal, w.slot) are possible
- overloaded signals - there are not many of them - e.g: clicked() and
click

They are used by SIP itself.

Is there a specific reason that sip doesn't support __gettattr__ and
__setattr__ special methods? Or does it and i'm just missing something?
Thanks,

If you could try to reproduce, that'd be nice. I attach two
Hello,
the assetmanager.pyw example doesn't seem to work correctly, or I'm using it
wrongly:
- The logs view always shows one empty line after the records belonging to the
selected asset. Why? When I try to write such a master-detail dialog myself,
using the asset manager as a model, I get eve

I find this one the most palatable :) Very logical too.

Can you give an example with two signals with the same name and such

*might* happen with signals from different classes but there,

I'wouldn't consider myself as an advanced PyQt developer, but for me it is.

Quoting Phil Thompson <[EMAIL PROTECTED]>:
I mean it is a very common mistake, even for advanced PyQt developers,
Is it?
In my projects, I'm predefining all signals and slots as python
constants and use those in connect() and emit(). a) makes the code
more reliable and b) enables code com
Quoting Henrik Pauli <[EMAIL PROTECTED]>:
But anyway: How much work would it be to have SIP generate constants
for all SIGNAL's in a class? So I could say:
self.connect(w1, w1.SOME_SIGNAL, ...)
Pro: Doesn't break old code, API, etc. No more typos (or python will
warn about a missing attri

Quoting Phil Thompson <[EMAIL PROTECTED]>:
From the documentation, I got the impression that the result of SIGNAL()
is more or less a constant. Is this code valid?
signal = SIGNAL()
self.connect(w1, signal, self.w1Clicked)
self.connect(w2, signal, self.w2Clicked)
Yes - given a corre
