Re: [Interest] Import C++ types to Javascript

[Jason H]

Thanks I;ll give that a shot, but what about a non-singleton? I think my code should be working now,  and I doon't know why it isn't. How to I make an instance?

For cpp you can use http://doc.qt.io/qt-5/qqmlengine.html#qmlRegisterSingletonType

 

put your function with Q_INVOKABLE or make it a slot.

 

Add your class to qml module.

 

Then you can call the singleton class function by importing your module.

 

MysingletonClass.myQInvokablefct()

This is new territory for me.  Could you tell me what i need to do for both?  In this case I can make a singleton,  but in the future maybe I can't.  

Many thanks.

If your object is not a singleton you will need to create an instance to call the function on that object. I suggestion you keep your staticfunction  call into a singleton. So you don't need an instance.

I just checked, it is a slot. I just feel like I'm missing something. Do I need to make a instance?

var instance = new MyLib.Hash() ?

var hash = instance.sha1("data")

Make sure your function is Q_INVOKABLE or is a slot. also take care .pragme library is not possible with _javascript_ and object from c++ access

Per http://doc.qt.io/qt-5/qtqml-_javascript_-imports.html

 

I am trying to in a JS file, import a class I made and exposed to QML via

 

hash.h:

class Hash :public QObject {

Q_OBJECT

...

QString sha1(QString str);

}

 

main():

qmlRegisterType<Hash>("MyLib", 1, 0, "Hash");

 

myfile.js:

.import MyLib 1.0 as MyLib

 

function myFunc(obj) {

 return MyLib.Hash.sha1(JSON.stringify(obj));

}

 

but what I get when I call it is:

qml: Parse Error: TypeError: Property 'sha1' of object [object Object] is not a function

 

What am I doing wrong?

JSON.Stringify-ing the MyLib or MyLib.Hash returns {}
