How to hide measure expression input in property panel

[ohenrichs]

Hi, so I have a definition for measures:

measures: {
    uses: "measures",
    min: 0,
    max: measureCount,
    items: {
        numberFormatting: {
            show: false,
        },
    }
}

It hides their default numberFormatting property. How can I hide the expression property? I did not find it after searching an hour 😞

I tried 

expr: {
    show: false,
},
expression: {
    show: false,
},
Expression: {
    show: false,
},

nothing works. What does?

Hi @ohenrichs,

I'm not quite sure what are you trying to do but see if this helps somehow. It removes the Dimensions and Measures boxes from an Extension.

definition : properties,
initialProperties : {
	version: 1.0,
	qHyperCubeDef : {
		qDimensions : [],
		qMeasures : [],
		qInitialDataFetch : [{
			qWidth : 0,
			qHeight : 0
		}]
	},
	fontSize : {
		min : 8,
		max : 24
	}
},

Hi Mark, 

thanks for the quick answer, I need to clarify. We auto-generate some measures for our extension, e.g.

Measure showing only Expression and Label

The code I posted above already removes the number-formatting. Now i want the Expression input to disappear, s.t. only the Label input is visible.

Best regards!

Hey @ohenrichs , so you are creating measure and you want to hide the Expression input box? Why do you need this? I don't think this is possible. If you do not have the expression, there will not be any measure.

Hi Alex, 

we have an extension that, based on other options in the property panel, creates and manages some measures. Our extension's logic requires their expressions to not be edited. So we want to forbid the user doing that for these specific measures.

I don't know a way for disabling the expression editor in a measure in chart properties panel. that part is designed for enable developers to insert expressions.

[ohenrichs]

Does that mean that someone else might know or that disabling is impossible? In the latter case I guess I have a feature request 😅 

Thanks anyway for replying!

One thing that you can do, is to hide the entire measure using the show property.
To my knowledge, there is no other way of doing what you are trying to do.

Thanks for the answer.

I actually also asked in Qlik's dev slack, someone had an idea that worked.

The item is called inlineMeasure

inlineMeasure: {
	show: false
},

This can also be expanded to only work for specific measures:

inlineMeasure: {
	show: (measure) => {
		// any rule you come up with
		return measure.props.YOURFIELD === "myDiscriminatingValue";
	}
},
