If your protoGlance is in the same view as your parent, you can call

 self:Parent().test:Open();

in the buttonClickScript. It worked for me.

In NTK? Open the Layout view, click into the window and choose protoGlance from the pulldown menu. Then click inside the window and drag open a rectangle. You can then edit it by double clicking it. Or you use Einstein Toolkit:


//
// NewtonScript example: Hello, World!
//

kAppName := "Hello:WONKO";
kAppSymbol := '|Hello:WONKO|;
kAppLabel := "Hello";

newt.theForm := {
    viewBounds: {
        left: 0, top: 50, right: 200, bottom: 120
    },
    _proto: protoFloatNGo
};

test := {
    text: "Soso",
    viewBounds: {
        left: 50, top: 170, right: 150, bottom: 200
    },
    _proto: protoGlance
};
AddStepForm( newt.theForm, test);
StepDeclare( newt.theForm, test, 'test);

helloButton := {
    text: "Say Hello",
    viewBounds: {
        left: 50, top: 25, right: 150, bottom: 50
    },
    buttonClickScript: func()
        begin
            self:Parent().test:Open();
        end,
    _proto: protoTextButton
};
AddStepForm( newt.theForm, helloButton);
StepDeclare( newt.theForm, helloButton, 'helloButton);
