Event
Event type. Can be one of the following values (FAR_EVENTS enum):
Event | Description |
---|---|
FE_CHANGEVIEWMODE | Panel view mode is changed. Param points to a null-terminated string specifying column types, for example N,S,D,T. Return value must be FALSE. |
FE_REDRAW | The panel is about to redraw. Param is equal to NULL. Return FALSE to use the FAR redraw routine or TRUE to disable it. In the latter case the plugin must redraw the panel itself. |
FE_IDLE | Sent every few seconds. A plugin can use this event to request
panel updating and redrawing, if necessary. Param is equal to NULL. Return value must be FALSE. |
FE_CLOSE | The panel is about to close. Param is equal to NULL. Return FALSE to close the panel or TRUE to cancel it. |
FE_BREAK | Ctrl-Break is pressed. Param currently can be only (int)CTRL_BREAK_EVENT Return value must be FALSE. Processing of this event is performed in separate thread, so the plugin must be careful when performing console input or output and must not use FAR service functions. |
FE_COMMAND | About to execute a command from the FAR command line. Param points to the command text. he plugin should return FALSE to allow standard command execution or TRUE if it is going to process the command internally. |
FE_KILLFOCUS | Panel has lost keyboard focus. Param = NULL. Return value must be FALSE. |
FE_GOTFOCUS | Panel received keyboard focus. The active panel receives the FE_GOTFOCUS event immediately after its creation. Param = NULL. Return value must be FALSE. |
