WLX Plugin - fontview_qt - QT6 version does not compile

[advice2020]

Linux / Debian based distro
Double Commander 1.2.0 alpha QT
QT6.4.2

WLX Plugin - fontview_qt

I recently tried to compile the QT6 version and for some reason this plugin does not compile.
The QT5 version compiles fine.

I have all the dependencies required by the plugin
build-essential pkg-config qt6-base-dev libgl-dev

make qt6 shows the following

g++ -shared -fPIC -Wl,--no-as-needed -o ../fontview_qt_qt6.wlx plugin.cpp  `pkg-config --cflags --libs Qt6Widgets Qt6Core Qt6Gui` -I../../../sdk -D'PLUGNAME="fontview_qt_qt6.wlx"' -D'DETECT_STRING="EXT=\"TTF\"|EXT=\"OTF\""' -D'PLUGTARGET="qt6"' || echo fontview_qt_qt6.wlx >> ../../../dist/.build_fail.lst
plugin.cpp: In function ‘void* ListLoad(HANDLE, char*, int)’:
plugin.cpp:67:44: error: ‘checkStateChanged’ is not a member of ‘QCheckBox’
   67 |         QObject::connect(bold, &QCheckBox::checkStateChanged, [preview](int state)
      |                                            ^~~~~~~~~~~~~~~~~
plugin.cpp:79:46: error: ‘checkStateChanged’ is not a member of ‘QCheckBox’
   79 |         QObject::connect(italic, &QCheckBox::checkStateChanged, [preview](int state)

I was wondering if anything shown above stands out as being the issue?
Am I missing a QT6 based library?

Thank You

QCheckBox::stateChanged was deprecated and replaced with QCheckBox::checkStateChanged from QT6.7 onwards

https://doc.qt.io/qt-6.7/qcheckbox-obsolete.html

I suspect that the information that you provided about using QT6.4.2 is wrong.

nah, my bad
now the version check should be set to a higher value

Ahh, thank you, I will give this a try when I have a chance.

Edit:
Was able to compile the QT6 version now, thank you again for updating this
