[Interest] Qt drag 'n drop indicator

[Murphy, Sean]

I'm setting up my application to allow the user to drop files onto my 
application to open them. I've got that part working just fine, but I'm trying 
to figure out how to customize the drop indicator as the user is drag the files 
onto my application. Right now I'm getting the attached image, which is some 
generic Windows thing (or maybe Qt is doing it, not sure...) and it says "Copy" 
over the image. The user isn't copying anything when they drop the files on my 
application, they're just trying to open them.

I've been reading through the drag and drop documentation and I can see how to 
set the image when I'm initiating the drag from an object within my 
application, but I'm missing how to do it when the drag starts from Windows 
itself

[bralchenko]

Yes, I think that’s the one.

 Patrick,
 
 you have to setGeometry(QRect screenGeometry) explicitly. screenGeometry 
 should be queried from iOS directly, like this:
 
 const CGRect r = [[UIScreen mainScreen] bounds];
 return QRect(0, 0, r.size.width, r.size.height);
 
 
 We had similar problem, black screen with AirPlay or with HDMI dongle. 
 This solved it for us.

Do you mean QMainWindow? That is the class that I am deriving from.

On main window, in our case it was derived from QQuickView.

Re: [Interest] Qt 5.8 font detection vs Qt 5.3.2 font detection

[Nikos Chantziaras]

When you compiled Qt, did you make sure fontconfig support was enabled? 
Is the fontconfig development package (probably called "fontconfig-dev" 
or something similar) installed on the system?

Hello,

My apologies if this question has been asked before. We are upgrading 
our Qt application running on Lubuntu 32-bit from Qt 5.3.2 to Qt 5.8. 
One of the issues we have ran into is font handling. The Qt 5.3.2 
version of our application detects the system fonts fine (the 
directories under /usr/share/fonts). However when starting the Qt 5.8 
version we get this error:


“QFontDatabase: Cannot find font directory”

The directory that QFontDatabase looks at is “/usr/local/lib/lib/fonts”, 
which of course does not exists.


The Qt 5.3.2 we use this the one that was provided by qt.io. The Qt 5.8 
version we compiled from source on a virtual machine.


We can get one of the directories to work by setting QT_QPA_FONTDIR, but 
our fonts are scattered over many directories.


What is the proper way of solving this problem?

Did we forget to configure some setting when compiling Qt 5.8 or has 
there been a change in behaviour and do we need to move all our fonts to 
one location?

Patrick,

you have to setGeometry(QRect screenGeometry) explicitly. screenGeometry should 
be queried from iOS directly, like this:

const CGRect r = [[UIScreen mainScreen] bounds];
return QRect(0, 0, r.size.width, r.size.height);


We had similar problem, black screen with AirPlay or with HDMI dongle. This 
solved it for us.

No problem:

https://www.qt.io/ -> Download Qt -> Desktop & Mobile Applications -> Get your 
open source package -> Download Now

or just

http://download.qt.io/official_releases/online_installers/
