## Detailed Description

An activate event is sent when a window or application is being activated or deactivated.

## Events using this class

The following event handler macros redirect the events to member function handlers 'func' with prototypes like:

void handlerFuncName(wxActivateEvent& event)

Event macros:

- EVT_ACTIVATE(func):
  Process a `wxEVT_ACTIVATE` event.
- EVT_ACTIVATE_APP(func):
  Process a `wxEVT_ACTIVATE_APP` event. This event is received by the wxApp-derived instance only.
- EVT_HIBERNATE(func):
  Process a hibernate event, supplying the member function. This event applies to wxApp only, and only on Windows SmartPhone and PocketPC. It is generated when the system is low on memory; the application should free up as much memory as possible, and restore full working state when it receives a `wxEVT_ACTIVATE` or `wxEVT_ACTIVATE_APP` event.

Note
  Until wxWidgets 3.1.0 activation events could be sent by wxMSW when the window was minimized. This reflected the native MSW behaviour but was often surprising and unexpected, so starting from 3.1.0 such events are not sent any more when the window is in the minimized state.

## Member Enumeration Documentation

## ◆ Reason

enum wxActivateEvent::Reason

Specifies the reason for the generation of this event.

See GetActivationReason().

Since
  3.0

Enumerator
Reason_Mouse | Window activated by mouse click.
Reason_Unknown | Window was activated with some other method than mouse click.

## Constructor & Destructor Documentation

## ◆ wxActivateEvent()

wxActivateEvent::wxActivateEvent | ( | wxEventType | eventType = `wxEVT_NULL`,
|  | bool | active = `true`,
|  | int | id = `0`,
|  | Reason | ActivationReason = `Reason_Unknown`
| ) |  |

Constructor.

## Member Function Documentation

## ◆ GetActivationReason()

Reason wxActivateEvent::GetActivationReason | ( |  | ) | const

Allows checking if the window was activated by clicking it with the mouse or in some other way.

This method is currently only implemented in wxMSW and returns `Reason_Mouse` there if the window was activated by a mouse click and `Reason_Unknown` if it was activated in any other way (e.g. from keyboard or programmatically).

Under all the other platforms, `Reason_Unknown` is always returned.

Since
  3.0

## ◆ GetActive()

bool wxActivateEvent::GetActive | ( |  | ) | const

Returns true if the application or window is being activated, false otherwise.
