No QCalendarWidget in designer? 4.2.0-tp1

[Spockmeat]

I just grabbed the 4.2.0 technology preview, and I was looking for that new QCalendarWidget in designer, but it doesn't seem to be there. Is this only accessible via code? Or is that something that will be added to the designer later?

Probably Qt Designer just wasn't updated. You can always create a plugin yourself.

Indeed. I've never made a plug in before but it seemed fairly easy. Here's the code for it if anyone cares:

calendarplugin.pro

CONFIG += designer plugin debug_and_release
TEMPLATE = lib
 
HEADERS = calendarplugin.h
SOURCES = calendarplugin.cpp
 
target.path = $$[QT_INSTALL_PLUGINS]/designer
INSTALLS += target

CONFIG += designer plugin debug_and_release
TEMPLATE = lib

HEADERS = calendarplugin.h
SOURCES = calendarplugin.cpp

target.path = $$[QT_INSTALL_PLUGINS]/designer
INSTALLS += target
