Dialog Boxes

The dialog boxes are widely used in Graphic User Interface (GUI) to display warning, errors, confirmations, etc. in special situation. Basically, there are two types of dialogs used in VTT. They are:

• Modal Dialog
  A modal dialog box blocks user input to all other windows in the same application when it is visible. Users have to close a modal dialog box before other windows in the same application can get focus.
• Modeless Dialog
  A modeless dialog box does not block user input. Accordingly, modeless dialog boxes can grow in number.
