Hi!
When selecting a font for a widget in Qt Creator 4.6.2, some of the fonts have
a postfix
[Qt embedded] in their name. E.g. "DejaVu Sans Mono [Qt Embedded]".
What does [Qt Embedded] mean exactly?

Yeah, I think I was misinformed or I misunderstood something at some point when

dynamic_cast returns nullptr when the class you are casting is cannot be
cast down to Type. Casting does not create a new instance for you.

I think I got confused myself with dynamic_cast, but of course what I had
in mind was not modifying the instance itself, but create a new
QApplica
Ha. I hope I didn't screw up this time.
#include
#include
#include
// returns true if 'a' is a subdirectory of 'b'
bool isSubdirectory(QDir a, QDir b)
{
while (!a.isRoot()) {
if (a.absolutePath() == b.absolutePath())
return true;
a.cdUp();
}

There's no such C++ concept as "promote a class". What you're asking is not
possible.

Except that this has a bug (which we had in Qt too): these two directories are
considered to be parent-ch

Hi there,
You can compare their absolute paths.
#include
#include
#include
int main(int argc, char *argv[])
{
QCoreApplication app(argc, argv);
QDir a("/Users/olegyadrov/one/two/three");
QDir b("/Users/olegyadrov/one/two");
QDir c("/Users/olegyadrov/one/four");

Hi,
I'm tinkering with using a Qt plugin that expects a QApplication in a
QGuiApplication (specifically, a QML application using QGuiApplication).
I'm not doing anything that causes a straight crash (or haven't run into that
one fatal instruction yet), but I do wonder:
is it in any way possible
Is there any way of finding if one QDir is a subdirectory of another? So for
instance:
C:\One\Two\Three
is a subdirectory of:
C:\One\Two
but not of:
C:\One\Four
Thanks.
