[Interest] How to make conditional compilation in QML

[Kristoffersen, Even (NO14)]

If I read your email correctly it would probably be better solution for your problem to have a single Loader and only load the model specified in the config file?

Loader { 
	id: 3DModel 
	source: getModelFile()   // Loads the corresponding QML file for the configured model
	asynchronous: true 
	active: model 
	onLoaded: { 
		origX = item.x 
		origY = item.y 
		origZ = item.z 
		file.modelLoaded = true 
	} 

	function getModelFile()
	{
		if (config === "QML1") return "3D/File1.qml";
		else if (config === "QML2") return "3D/File2.qml";
		etc.
	}
}

Subject: [Interest] How to make conditional compilation in QML

Hello, 

      I am using 5 different 3D models on my display.  Each model is a seperate QML file. 
These models are loaded as below using the Loader.  At any given time there can be only one model enabled. 
The enabling is done prior to compilation. 

Please suggest me how can I compile only one of the 5 different QML files that are available in the project. 

There is a configuration XML file in which either of the ids are chosen i.e from QML1 to QML 5. 

I was thinking of doing a conditional compilation based on the model that is being selected, but I do not know how it is done in QML.. 


Config XML file as below////////////////////////////////////////////////////////////////////////////////////////////////////////////////// 

<3d> 
                <model>QML2</model> 
                <!-- QML1/ QML2/ QML3/ QML4/ QML5--> 
</3d> 


Loader Code used in QML as below/////////////////////////////////////////////////////////////////////////////////////////////////7 

    Loader{ 
        id: QML1 
        source: "3D/File1.qml"    // Loads the corresponding QML file

        active: model 
        onLoaded: { 
            origX = item.x 
            origY = item.y 
            origZ = item.z 
            file.modelLoaded = true
