Print hook not working
This is the code I use for creating the hotkey:
d_hotkey = new QHotkey(Qt::Key_Print, Qt::NoModifier, true, this);
qDebug() << "Is registered:" << d_hotkey->isRegistered();
It is printing true, but however many ways I try to connect the signal to a slot, it just doesn't work. It either prints:
qt.core.qobject.connect: QObject::connect: signal not found in QHotkey
or straight up doesn't do anything.
I'm on a Windows system.
Any ideas why this could be?
As I said, I've tried every way I know.
QObject::connect(d_hotkey, SIGNAL(activated()), this, SLOT(printCaught()));
QObject::connect(d_hotkey, SIGNAL(activated(QPrivateSignal)), this, SLOT(printCaught(QPrivateSignal)));
QObject::connect(d_hotkey, &QHotkey::activated, this, [&](){
...
});
QObject::connect(d_hotkey &QHotkey::activated, this, &TrayHandler::printCaught);
TrayHandler is the type of *this.
I think there were a few more I tried but I don't remember.
qt.core.qobject.connect: QObject::connect: signal not found in QHotkey
This message just says that you connected it wrong. Probably from one of the attempts.
But last two are 100% good. So the shortcut is not emitted for some reason.
Hm.. I get the warning on the lambda one so that's interesting. I also thought it would be good since that's in the example in the readme. Same with the last one.

That's impossible.
Also, just to clarify, Qt::Key_Print is print screen right?
Right.
I can't reproduce it, the example from the README works jut fine for me without this message. It could be cause only by the old connect syntax. Something wrong with your code.
Could it be with the way I add the dependency? Because it feels kinda wrong. That's the only thing I can think of at this point, since the HotkeyTest example works.
Cmake code:
find_library(QHOTKEY_LIBRARY NAMES qhotkey1 QHotkey1 HINTS "${CMAKE_PREFIX/lib}")
target_link_libraries(QuickScreenshot PRIVATE ${QHOTKEY_LIBRARY})
Because it feels kinda wrong. That's the only thing I can think of at this point, since the HotkeyTest example works.
You probably using it wrong. Try this one:
cmake_minimum_required(VERSION 3.16)
project(project LANGUAGES CXX)
include(FetchContent)
option(QHOTKEY_INSTALL OFF)
FetchContent_Declare(QHotkey
GIT_REPOSITORY https://github.com/Skycoder42/QHotkey
GIT_TAG 1.4.2
)
FetchContent_MakeAvailable(QHotkey)
add_executable(${PROJECT_NAME} main.cpp)
target_link_libraries(${PROJECT_NAME} PRIVATE QHotkey::QHotkey)
It's trying to search for Qt5 for some reason.
By not providing "FindQt5.cmake" in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by "Qt5", but
CMake did not find one.
Could not find a package configuration file provided by "Qt5" with any of
the following names:
Qt5Config.cmake
qt5-config.cmake
Add the installation prefix of "Qt5" to CMAKE_PREFIX_PATH or set "Qt5_DIR"
to a directory containing one of the above files. If "Qt5" provides a
separate development package or SDK, be sure it has been installed.

Clearly CMake can't find Qt5 for you.
Then you maybe want to set QT_MAJOR to 6?

Erm... how do I do that though? Since that's in the github repo
How about to put set(QT_MAJOR 6) in your CMakeLists.txt before including QHotkey?
Are you aware that you should put it before
FetchContent_MakeAvailable? Yes, and I did.
I'll try the other one in about an hour because I have to go.
Or try this one:
set(QT_MAJOR 6 CACHE STRING "Use Qt6")
doesn't seem to work either
I don't have much information to understand what are you trying. But you need to find a way to override this variable.
The default qt script uses the variable called QT_VERSION_MAJOR so it doesn't make sense why I need this one.
And I'm trying what you told me but it doesn't seem to do a thing.

Because this won't work with old Qt versions.

I just guessing. You are not providing enough information for me to help you.
