Print hook not working

[diniamo]

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?

How do you connect to the signal?

[diniamo]

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.

[diniamo]

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.

[diniamo]

Also, just to clarify, Qt::Key_Print is print screen right?

[Shatur]

That's impossible.

Right.

[diniamo]

That's impossible.

[Shatur]

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.

[diniamo]

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})

[Shatur]

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)

[diniamo]

Oh I can do that?
huh lemme try

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.

That's because I use Qt6 lol.
