Enabling support to print visualization extensions

In Qlik Sense 3.0 support for printing extensions has been added. Therefore it is now possible to:

• Export a single extension as image (right click)
• Include visualization extensions in stories and print the story.
• Include visualization extensions if a PDF for the current sheet is created.

To enable this functionality the following changes need to be made to (existing) visualization extensions:

Meta data

To tell Qlik Sense that your visualization extension should be enabled for printing, add the following properties:

    
    definition: {
        ...
    },
    support: {
        export: true
    },
    paint: function() {
        ...
    },
    ...

Finished rendering notification

Then in the paint method the printing service needs to be informed that the extension has finished rendering:

    
    // ...
    paint: function() {
        
        return qlik.Promise.resolve();
    }        
    // ... 
    

So even in case your visualization extension is loading data from an external source and it takes some time that rendering is finished, this solution will take care of that:

    paint: function() {
        
        whateverAsyncTask().then( function() {
            return qlik.Promise.resolve();
        });
        
    }

Qlik Sense server & printing (export)

Note that settings defined in your Qlik sense visualization extension can be overruled in Qlik Sense server's management console:
