Multi 'page' QML application issues with external QML/Javascript

[anda_skoa]

Property bindings look like they will work fine for my purpose.

Excellent, bindings on C++ properties is definitely the way to go.
Way more elegant than making C++ code dependent on QML code.

When calling my javascript functions, why can I not access my QML objects? I get errors about the object being undefined. I've tried by using the alias for the object, the id for the object and the QML file name that houses the object....all give the same error.

Can you show such a function and where the objects are defined?

For example your gpsOneShotUpdate() function should be fine if there is an object with id mainWin in the same file or a property with the name mainWin in the object the function is in.

AND... do I need to 'import' the parent and SubPages folders into each of my SubPages/*.qml files?

import allows you access to types, just like includes in C++.
The current directory, i.e. the directory the current QML file is in, is always implicitly imported.

In your case you don't need to import SubPages in main.qml since you are using a Loader, you are not instantiating objects of these types directly in QML code.

I ask because if I try to reference an object in SubPages/Page1.qml from SubPages/Page2.qml, I get an error about that object being undefined.

Access to objects has nothing to do with imports.

For instance, when I load SubPages/Page2.qml using the loader I showed earlier. Page2 has a Label that when clicked on will change a value on Page1. But, if I try this I get an error:

In Page2:

onClicked: {
                Page1.page1Label.text = page2Label.text
                Page1.page1Label.color = "lime"
                page2Label.color = "darkred"
            }
        }

onClicked: {
                Page1.page1Label.text = page2Label.text
                Page1.page1Label.color = "lime"
                page2Label.color = "darkred"
            }
        }

To copy to clipboard, switch view to plain text mode 

Page1 is not a valid id nor a valid property name (both need to start with a lower case letter).

Ok, I ended up declaring non-visible instances of the SubPages in my main.qml. Works pretty well with my custom 'loader' javascript function to show/hide each page on demand.

Thanks for the help!

You really like doing things imperatively :-)

However, you might want to look into doing things declaratively for future projects, it really pays off and makes things easier.
