• Demonstration
• Functionality:
  • the user enters the characters from the keyboard; after the key i pressed a new popup window appears with the given character as the title
  • the popup windows appear in a grid with fixed number of columns and rows (make sure that the characters cannot be entered outside of the grid)
  • at least the following characters must be available: 'A' to 'Z', 'a' to 'z', '0' to '9' and ' ' (space)
    • use Shift key to enter upper case characters
  • pressing Enter key moves to the next row
  • pressing Backspace key removes the last character in the table, and the appropriate popup window
  • entering the characters should be possible when either the main window or any of the popup windows is active
• The main window:
  • moving the main window should make all the popup windows to move as well
• Popup windows:
  • features:
    • not sizeable
    • always on top
    • not visible on the taskbar
  • popup windows have to be placed relatively to the top left corner of the main window
  • each popup window contains a small client area; clicking the left mouse button on the client area and moving the mouse up and down forces the character on the title bar to change periodically
    • while the left mouse button is hold, the characters should change even if the cursor goes out of the popup window client area
• Hints:
  • WM_KEYDOWN, WM_LBUTTONDOWN, WM_LBUTTONUP, WM_MOUSEMOVE, WM_MOVE
  • VK_RETURN, VK_BACK, MK_LBUTTON
  • SetCapture(), ReleaseCapture()
  • MoveWindow(), ClientToScreen()
  • SetWindowText(), GetWindowText(), wsprintf() [sprintf(), _stprintf()], wchar_t [char, TCHAR]

  • changing the characters with the mouse: 3.0
  • moving the windows: 2.0
