[Marco Piccolino]

In what scenarios would it still make sense to use QtWidgets for new
projects?

Thanks

 Hello! Has anyone else had a problem with Qt apps only showing as
 a black screen when mirroring an iOS device over airplay? Other
 apps display fine, but then the AirPlay display turns black when
 the Qt app is brought to the front.
 
 Granted, I am using Reflector 2 to show the iPad screen on my Mac
 with latest macOS Sierra, (in order to show the iPad on a
 projector), but it just uses the AirPlay protocol on the iOS end
 so I assume it is a problem with the Qt iOS view.

Re: [Interest] [Development] Calls for Presentations open for Qt World Summit 2017 and Meeting C++

[Tero Kojo]

Thanks Milian,

Looks like by default the option for multiple responses is turned off.
Reading the manual helped, it should now be turned on.
If it still doesn't work ping me directly.

Best,
Tero

Why don't you just build QtCreator for source then? You can then compile
it against the Qt version you have on your system. Sounds like way less
hassle than trying to fiddle with getting other IDEs to run.

Really, on a distro that’s trying to use Qt for everything?  Well, I installed 
it on a spare partition recently (mainly to check out the new global-menu 
feature), checking...

$ sudo apt-get install qtcreator
...
The following packages have unmet dependencies:
 qtcreator : Depends: qtbase-abi-5-5-1
 Depends: qtdeclarative-abi-5-5-0
 Recommends: qmlscene
 Recommends: qt5-qmake
 Recommends: qtbase5-dev-tools
 Recommends: qtcreator-doc but it is not going to be installed
 Recommends: qtdeclarative5-dev-tools
 Recommends: qtxmlpatterns5-dev-tools

Wow, how embarrassing.  Why are they stuck with 5.5-something?

https://forum.kde.org/viewtopic.php?f=309=136886

Well, at least you can download and install the Qt SDK.  I tried; it runs.  
Somebody suggested that there too.

What does that mean?

I wasn’t really aware of it before… don’t think I ever tried it.

Why?
