I have just tried the sky box entity with Qt-5.9-beta, and found a

Hi there,
I can create a valid QVariant that contains a MyObject pointer with
just the class name (ie, QString("MyObject")) and no access to the
class declaration. MyObject is derived from QObject.
This QVariant has the following properties:

- userType() == QMetaTyp

Hi there,
On my Linux computer (KUbuntu 16.10, AMD CPU), I'm having a big

ellipse with a drop shadow effect. When zooming in, the CPU usage goes
to 100% and the view takes ages to draw.
This is very simple to reproduce, no need for a
Hi there,
I need to substract a shape from another using QPainterPath, if the 2
shapes don't intersect and the outer fully contains the inner, the
most effective way to do that is:
resultPath = solidPath.addPath(cutoutPath);
This works well and is fast, given that the path use the right fill
rule
is that the bounding region/rect of the item is
expressed in device coordinates (pixels), and the item transform is
relative to parent (or scene) coordinates, so you cannot mix both.

My feeling is you should try to remove as much logic as possible from
here, there are too many things hapennin
ble without CMake.
Anyway, I would prefer a solution based on Qt IFW and Qbs.

Hi there,
I've recently added a (very basic) offline installer to my project
using the Qt installer framework and i'm looking for a multi platform
solution to detect my app dependencies and to ship (some of) them into
my installer.
Ideally I would like to automate this...

Hi there,
I'm on Ubuntu Linux 16.04, i have installed Qt 5.5, 5,6 and 5.7 using
the Qt unified online installer. I would like to know if it is
supported to build a Qt app using clang++/64 and Qt 5.x gcc/64
official binaries.
Right now, I'm having building errors like:

Hi there,
I have an application that use heavily the Qt graphics view framework,
where each item represent a flat, solid object on a layer of material.
They all have a "simple" shape, that is they only use line and arcs
and have no windings/overlaps. Items represents a deposit of material
or a mat

Hi There,
I have sub-classed a QGraphicsView to add some custom rulers on the
top and on the left.
For this I've followed the principle used here [1], basically what's
done there is:
- set a QGridLayout to the QGV
- Add an horizontal ruler at top and left
- set QGV's viewPort as the "central widge
Hi Denis,
Indeed it would be nice to have an extended API for controlling vendor
specific extension in a uniform way.
Switching between RS232/422/485 is a pretty common feature (including
switching b/w full/half duplex, (des)activating termination resistor),
as is controlling a few extra GPIO. The
Hi there,
According to the documentation of "bool QVariant::canConvert(int
targetTypeId) const" [1] a QVariant holding a QString should be able
to convert to QChar as "QMetaType::QString converts automatically to
QMetaType::QChar"
but the following code:

Hi there,
In short, here is the problem I'm trying to solve:
Given a shared object that contains QObject derived classes, I want to:
- Enumerate the class names
- Create instances of these class and interact with them
I would like to do that with Qt and I would like it to be platform
independent
Hi there,
Couldn't find anything related on the net, so asking here:
FitNesse[1] is a wiki based acceptance testing framework, it includes
a (very basic) C/C++ 'SLim' server.
Has anyone around here used the 'FitNesse' acceptance testing
framework with a Qt based application?
The C/C++ server ha
