MAGNIFY

Compiling

To compile the example:

  • Launch EiffelStudio.
  • Click Add project
  • Browse to $ISE_EIFFEL\examples\wel\magnify\.
  • Choose magnify.ecf
  • Choose the location where the project will be compiled, by default the same directory containing the configuration file.
  • Click OK.

Running

After launching the application, you will see a window displayed with a similar appearance to the one above. Selecting "Quick reference..." from the "Help" menu will display the full instructions for using this application.

Under the Hood

In order to be able to control the output of the sample, MAIN_WINDOW redefines many features from WEL_FRAME_WINDOW . The feature draw_zoom_rectangle is used to display the output and on_menu_command handles the notifications sent to the window when a menu_selection has been made.

This sample contains the following classes:

  • APPLICATION_IDS
  • MAIN_WINDOW
  • MAGNIFY_DEMO
