Composing QML objects from different files: Accessing functions in parent

[maxwell31]

Hi,

Lets assume I have a file Plot.qml and files PlotOverlayA.qml and PlotOverlayB.qml. I don't want to move PlotOverlayA into Plot.qml as it is only needed in some circumstances and my Plot.qml file would get quite bloated if I moved every component there.

If I use my plot component, I would like to do something like

Plot {

    PlotOverlayA {

    }

}

Plot.qml has a signal update and I would like to connect to this signal in PlotOverlayA.qml. If I receive this signal in PlotOverlayA, it should bexecute a function defined in Plot.qml (like getXCoordinates). However, I don't know how I can access the functions of Plot.qml.

Maybe I don't understand, if you connect signal update in Plot with function in in the same file it doesn't enough? You can also connect signal from Plot with something in PlotOverlayA using id property

What I am trying to do is to create a flexible and reusable plot component. I would like to keep the interface (the properties of Plot.qml) small, and hope that this is achievable via "extending" the Plot component e.g. with a PlotOverlay as shown above. So PlotOverlay should be seen as tightliy coupled to plot. I will try with the id

Do you mean "emit the signal" in here?

are the PlotOverlayA only children item of Plot?
