Re: H2.06: Optional Text or Images chage before new screen change
To change the properties of widgets on the screen before they are rendered to the framebuffer, you can enable the "On Show" event callback for the screen. In MHGC, go to Tools->Event Manager to open the Event Manager window. In the Event Management window under "Screen Events", check the "On Show" event call back for the screen. In the Actions sub-window, click the "+" sign to add either a custom or a templatized action to change the properties (text, image, etc.) of widgets on the screen. After regeneration, the callback function (<screen>_OnShow()) will be in the libaria_events.c file.
The Event Manager tool is discussed in more detail in the Harmony Help Vol. III -> MHGC User's Guide -> MHGC Window User Interface -> MHGC Tools -> Event Manager.
