MDI

Version A

Excuse me, Sir, how can I get to Lewisham?

• Demonstration
• The main window:
  • in the background: London Underground Plan (the image can be downloaded here)
    • the image fits the client area
  • non-sizeable, non-scrollable
  • with menu options (appearing only when there is at least one child window / the menu options give the results as on the demonstration):
    • cascade
    • tile
    • arrange icons
    • close all
• Child windows:
  • contain the part of the bitmap, in its original resolution
    • the middle point of the image in child window is similar to the point behind it on the client area
  • two different kinds of child windows: the first uses the original bitmap, the second uses inverted bitmap
  • executed from the menu
  • sizeable
  • each window is prompted before closing
• Requirements:
  • all drawing should be flicker-free
  • all created GDI objects must be deleted
  • objects selected as current on DC must not be deleted
  • avoid compilation warnings
  • the bitmap should be stored in and aquired from the resources
  • the program has to be an MDI application
• Approximate points:
  • MDI (with options): 3.5
  • proper drawing: 3.0
  • functionality: 3.5
