Mouse middle click on textBlock

GoJS
1

Hi

I’m trying to find the way to implement link behavior, like html <a> tag works.
There is no issue with mouseClick event, but I also need to handle a “middle” click, which in html for <a> by default opens a new tab in browser.
Is there a way to handle that?

Thanks
Vlad.

Override ClickSelectingTool.standardMouseClick, call the super method for the standard behavior, and then check for InputEvent.middle.

    $(go.Diagram, "myDiagramDiv",
      {
        "clickSelectingTool.standardMouseClick": function(navig, pred) {
          var result = go.ClickSelectingTool.prototype.standardMouseClick.call(this, navig, pred);
          if (this.diagram.lastInput.middle) {
            // can look at this InputEvent.targetObject to see exactly what was clicked
            var elt = this.diagram.lastInput.targetObject;
            alert("middle button on " + elt ? elt.part.key : "");
          }
          return result;
        },
        . . .

Walter, it works perfectly every where except tooltip. this.diagram.lastInput.targetObject is null in case of i’m clicning something inside tooltip. I’m clicking textblock inside tooltip. Tooltip is made as Adornment.

I haven’t tried this, but you could try instead:

var result = go.ClickSelectingTool.prototype.standardMouseClick.call(this, null, null);
