Different delegates in TableViewColumn depending on data

SebastianM

In QTableView with custom delegate in createEditor I can provide any widget I want to display my data. I have access to model, so I test what data are inside and display them with different widget.

How to achieve the same in TableView/TableViewColumn?

	TableViewColumn{
		title: "Value"
		role: "propertyValue"
		movable: false
		delegate: {
			type = propertiesTableView.model.data(propertiesTableView.model.index(styleData.row, styleData.column), 0x0100);
			//styleData is not defined
			console.log("Type value for row '"+styleData.row+"' is "+type)
			if (type == 1) 
				return NodePropertyDelegate.floatDelegate
			else if (type == 2)
				return 0

I tried this - but styleData is not present, so I don't know how to get type from model.

deletegate should be Component. In your code you are writing code directly.

delegate : Rectangle {
      width:100;height:100;color:"blue"; 
      Text {
         text : styleData.value
       }  
}

Any processing inside the delegate can be done with appropriate signal handler inside the signal handler of component.

Please take a look into sensor_explorer example (Qt 5.11+).
There's part of code

                itemDelegate: {
                    if (selectedItem && selectedItem.isWriteable)
                        return editableDelegate;
                    return readOnlyDelegate;
                }

where code makes selection what to display as delegate depending on few properties of TableView.
I'm referring to this kind of code to select which delegate to show.

You could use DelegateChooser

Cool, that's what I was looking for.
