[Qt-interest] QDateEdit minimum date is year 100

[Maximilien Renard]

Hi there,

I'm currently developing a electronic patient record managing program and
I've stumbled upon a quite annoying problem.

QDateEdit allows a minimum date only back to the 100-01-01. I've checked the
Qt bug tracker and found an issue about this problem that was closed. It was
said that Qt developers would take a look at this for the release of Qt 5.0

After having checked, I found that QDate lets us input any kind of dates
(including negative years).

It seems that the issue is difficult to fix since they plan to look at this
only with the release 5.0 (when is that planned btw ?) but couldn't it be
possible to make the QDateEdit display 0000-00-00 when a any date below
100-01-01 is given and return an invalid or null date when calling date() ?
Although I haven't checked the source code of Qt yet, it doesn't seem to me
that this should be that difficult. It would be a quick but very useful fix
for people using databases (like me :P) since the date 0000-00-00 is used as
the null date (with MySQL at least).

 My questions are the following : 1) What do you think about this idea ? 2)
I'm not familiar with bug tracker, should I create a new issue to make this
suggestion or is this the place to do it (in which case there would be
nothing else to do but wait for an answer :) ) ?

Thank you very much for your future answers,


Kind regards,
