Cross-sectional task

Mouse cursor tracing

• Demonstration
• Functionality:
  • application traces mouse cursor (with intervals about 50ms)
  • main window of the application is invisible at start
  • the only visible effect of application start is an icon in tray area
    • icons should be loaded from resources
    • double-click on application tray icon shows/hides drawings following the mouse cursor
      • icon used as a tray icon should be corresponding to drawings visibility (see demonstration)
    • tray icon has a context menu with one menu item - "Exit" - which ends the application
• Technical requirements:
  • Alt+F4 shortcut does not close the application
  • mouse cursor is traced by propellers drawings
    • diameter of the propellers changes linear from 12 to 32 pixels
    • numer of the propellers is constant (24)
    • propellers have 50% opacity
    • propellers rotate clockwise
    • all the drawing should be flicker-free
  • icons to be used in the tray area: task11_trayIcons.zip

• Approximate points:
  • tray icon with context menu: 2.5
  • tracing mouse cursor with blue propellers: 5.5
  • propellers animation: 2.0
