3 | A focus event is sent when a window's focus changes. The window losing focus | |
4 | receives a ``kill focus'' event while the window gaining it gets a ``set | |
5 | focus'' one. | |
6 | ||
7 | Notice that the set focus event happens both when the user gives focus to the | |
8 | window (whether using the mouse or keyboard) and when it is done from the | |
9 | program itself using \helpref{SetFocus}{wxwindowsetfocus}. | |

22 | To process a focus event, use these event handler macros to direct input to a member | |
23 | function that takes a wxFocusEvent argument. | |

47 | Returns the window associated with this event, that is the window which had the | |
48 | focus before for the \texttt{wxEVT\_SET\_FOCUS} event and the window which is | |
49 | going to receive focus for the \texttt{wxEVT\_KILL\_FOCUS} one. | |
