Method OO_APP_VIEWER (0xE) BOOL AppViewer(AppID self, BYTE * vartype, WINDOW *, HSYM symbol) The [F6: Contents] menu command of the VAR-LINK window calls this method of each application in turn until one of them returns TRUE. If an application knows how to display variables of type vartype, it displays the contents of variable symbol in the given window and returns TRUE. This method is optional. Applications which implement new data types may use this method to display a variable it understands in the VAR-LINK contents window. If no application returns TRUE, then the variable's contents are not displayed. 7.3.1.3.15. Attribute OO_APP_ICON (0xF) BITMAP * GetAppIcon(AppID) A pointer to a BITMAP which represents the application's icon. This attribute is optional. 7.3.1.3.16. Method OO_APP_EXT_HELP (0x10) void AppExtHelp(AppID self, USHORT strnum) The catalog screen calls this method when the users presses [F1: Help] for a function or command extension implemented by the application. This method is optional. It should only be implemented if the application exports TI-BASIC extensions. The system implementation of this method displays the extension's help string if this method is not implemented. 7.3.1.3.17. Method OO_APP_NOTICE_INSTALL (0x11) void AppNoticeInstall(AppID self, ACB const *) The OS calls this method in every application when a new application is installed. The app is passed a pointer to the new application's ACB. This method is optional. 7.3.1.3.18. Method OO_APP_ABOUT (0x12) char const * AppAbout(AppID self) The VAR-LINK screen calls this method when a user presses [F6: Contents] for a Flash application. The application returns a pointer to a string containing version and copyright information. TI-89 / TI-92 Plus Developer Guide Not for Distribution Beta Version January 26, 2001
