QDateTimeEdit with date *and* time picker

[Stefan Scherfke]

Hi,

I want to create a DateTimeEdit with a popup that contains both, a date picker and a time picker (as shown in the image below or in this live example).

I have read the docs of QDateTimeEdit and QCalendarWidget and also read parts of QDateTimeEdit's source code, but I am still not sure what would be the best approach to implement this (in PyQt5, but I guess whether I do it in Python or C++ is not too important for the general approach).

The internal QCalendarPopup class already seems to have a layout component that could, in theory, contain a calendar widget as well as a "TimeSelectionWidget". However, I have no idea how to extend it in a clean way.

Cheers,
Stefan

@Stefan-Scherfke
i haven't tried it but it should be possible:

QDateTimeEdit* dt = new QDateTimeEdit;
QWidget* popup = dt->calendarWidget()->window();
QListView* timeList = new QListView;
//init timeList widget

QWidget* container = new QWidget;
// set the layout and add the "calendar widget" and "timeList" widgets (and buttosn) to your needs

QVBoxLayout *popupLayout = qobject_cast<QVBoxLayout*>(popup->layout());
QLayoutItem *item;
 while( (item = popupLayout ->takeAt(0)) )
         delete item;
popupLayout->addWidget( container );

Also you need to make sure to select the time (in the time list view) whenever the datetime changes.

@raven-worx Thank you very much!

I already got a minimal example working. I'll post a complete example once everything works well. :)

I made some progress and the new widgets looks quite good (not perfect, though):
.

The problem with resizing and spacing everything correclty is, that I can't access all of the calendar widget's privates stuff.

This also leads to problems with signals/slots. By default, the calendar popup sets the DateTimeEdit's date and closes, if I click on the month calendar. However, I only want to to set the Date/Time and close the Window when I click on the Done button, so that I can select a Date, an Hour and Minute. Therefore, I need to disconnect the original signals, but they are not accessible, too.

I don't really want to write my own CalendarWidget-clone just to do these minor modifications. What else could I do?

Hi
Did you try implementing mousePress and not call base class?
You can maybe eat the mouse event that triggers the signal to be sent and
that way remove the popup.

@Stefan-Scherfke said in QDateTimeEdit with date *and* time picker:

Possibilities:

1. install an event Filter on the popup widget (window) and intercept the CloseEvent and call ignore() on it and return true in the event-filter
2. call blockSignals(true) on all widgets which shouldn't trigger signals
