A reference to the topmost window in the window hierarchy.
If this WindowBase is the topmost WindowBase, top will return a reference to the WindowBase itself.
// Add an IFrame to the current window. IFrameElement myIFrame = new IFrameElement(); window.document.body.elements.add(myIFrame); // Add an IFrame inside of the other IFrame. IFrameElement innerIFrame = new IFrameElement(); myIFrame.elements.add(innerIFrame); print(myIframe.contentWindow.top == window) // 'true' print(innerIFrame.contentWindow.top == window) // 'true' print(window.top == window) // 'true'
WindowBase get top => _convertNativeToDart_Window(this._get_top);
