The main parent window has been made modal and unaccessible by setting dhtmlxwindow’s setModal property:
var dhxWins = new dhtmlXWindows();
dhxWins.enableAutoViewport(true);
w1 = dhxWins.createWindow("w1 ", 20, 20, 100, 200);
w1 .setModal(true);
w1 .keepInViewport(true);
But if we scroll in the main parent window, the portion after scrolling in the main window becomes accessible.
So, how can we set the modal property in such a way that even after scrolling in the parent window, the portion behinf the scroll is unaccessible. i.e., scrolling should not make the parent window accessible and dhtmlxwindow as still modal.
