Differences between WINDEV and WINDEV Mobile: Managing the menu options

The menu options (in main menus or in popup menus) can be managed by the Menuxxx functions and by the corresponding properties.

To optimize the size of the WINDEV Mobile framework installed on the Mobile device (Pocket PC), only the properties can be used to handle the menu options by programming.

The equivalence table is as follows:
