Can't use C++ method in Qml side : Insufficient arguments
I have made a C++ class that I use to make some calculation.
I this class I have some INVOKABLE methods. I exposed the C++ by registering it as a type with this line :
qmlRegisterType<Calculs>("CustomControls", 1, 0, "Calculs");
I'm trying to use thos method in the main so I added a component "Calculs" with an id in the main.qml, then I call it from a Js function. My problem comes when the function is called. I have this error :
Error: Insufficient arguments
My C++ method use 3 double as input arguments, when I call my function I use this line :
var result = calc.getValue(1,2,3)
I don't really understand how could I have insufficient argument with this line.
Does anybody have a clue ?
Thank you in advance
var result = calc.getValue(1.0, 2.0, 3.0)
@tracyma seems to works, thank you I belive it is due to format issu when I call the method.
Finally as soon as I use a variable from a TextField it does the same thing.
Here is how I convert the text to float :
var floatValue= parseFloat(myTextField.getText())
I'm not sure the conversion works properly.
Is there any problem using this as a variable of my method ?
You must use
myTextField.displayTextto get the text. Both these are QML properties.
getText()is a QML method, which does something else than you probably think it does, and which requires arguments, hence the error.
@Diracsbracket That was my problem here ! Thank you !
