Qt6.8 remove operator== for many class

zhangqi2023 commented 1 week ago

Take QDir for example:

#if QT_CORE_REMOVED_SINCE(6, 8)
    bool operator==(const QDir &dir) const;
    inline bool operator!=(const QDir &dir) const { return !operator==(dir); }
#endif

Is that why I can't build the example anymore?

the example I ran:

package main

import (
    "fmt"
    "os"

    qt "github.com/mappu/miqt/qt6"
)

func main() {

    qt.NewQApplication(os.Args)

    btn := qt.NewQPushButton3("Hello world!")
    btn.SetFixedWidth(320)

    var counter int = 0

    btn.OnPressed(func() {
        counter++
        btn.SetText(fmt.Sprintf("You have clicked the button %d time(s)", counter))
    })

    btn.Show()

    qt.QApplication_Exec()

    fmt.Println("OK!")
}

I can confirm the problem on Fedora 41 with Qt 6.8.

Many operator== overloads were changed from class methods into global methods. In C++, writing a == b works for either, and is unaffected by this change. But because MIQT generated code like a->operator==(b), it was affected.

I'll change MIQT to use the a == b format in such cases.

Qt 6.8 is now working on Fedora 41. Please upgrade to master and try it out.

In future, Qt 6.8 will be tested in CI automatically so that it keeps working.

Qt6.8 remove operator== for many class #84
