WM_GETOBJECT top-level constant Null safety

int const WM_GETOBJECT

Sent by both Microsoft Active Accessibility and Microsoft UI Automation to obtain information about an accessible object contained in a server application.

Applications never send this message directly. Microsoft Active Accessibility sends this message in response to calls to AccessibleObjectFromPoint, AccessibleObjectFromEvent, or AccessibleObjectFromWindow. However, server applications handle this message. UI Automation sends this message in response to calls to IUIAutomation::ElementFromHandle, ElementFromPoint, and GetFocusedElement, and when handling events for which a client has registered.

Implementation

const WM_GETOBJECT = 0x003D;
