how to best set OS specific properties in plugin

• Sep 10, 2019 - 20:58

Hello.

I need some properties to adapt to the OS, namely file paths and executable location. For now they are commented in the script, up to the user to uncomment the ones s.he needs... but that's not nice for non developpers.

The compile-time macro #ifndef Q_OS_WIN don't seem to work.

What are other (better) options to make some part of the QML code OS-aware ? (mostly distinguishing Linux; from Windows; from MacOSX)

Thanks.
Berteh.

See https://doc.qt.io/qt-5/qml-qtqml-qt.html#platform-prop

Looks like testing Qt.platform.os will do the trick.
If you have better options feel free to comment, of course !
doc: https://doc.qt.io/qt-5/qml-qtqml-qt.html#platform-prop

if (Qt.platform.os === "linux" || Qt.platform.os === "osx" || Qt.platform.os === "unix") {
    // ...
} else if (Qt.platform.os === "windows" ) {
    // ...
} else {
    // ...
}

That's what I hinted at ;-)

yes, thanks. But I'm not allowed to use the (dynamic) if test in the class properties areas, or is there any way in QML ? (sorry for my poor JS knowledge).

I ended up using syntactic sugars. Works... but not great if you need to test for multiple platforms or have many properties... so better options are still welcome.

property string mmaPath : Qt.platform.os == "windows" ?winMMAPath:nixMMAPath;
property string midPath : Qt.platform.os == "windows" ?winMIDPath:nixMIDPath;
property string mmaCommand : Qt.platform.os == "windows" ?"cmd.exe /c "+winMMACommand:nixMMACommand;
