The GUITHREADINFO structure contains information about a graphical user interface (GUI) thread.
Syntax
typedef struct tagGUITHREADINFO {
DWORD cbSize;
DWORD flags;
HWND hwndActive;
HWND hwndFocus;
HWND hwndCapture;
HWND hwndMenuOwner;
HWND hwndMoveSize;
HWND hwndCaret;
RECT rcCaret;
} GUITHREADINFO, *PGUITHREADINFO;
Members
- cbSize
-
Specifies the size of this structure, in bytes. The caller must set this to sizeof(GUITHREADINFO).
- flags
-
Specifies the thread state. This member can be one or more of the following values.
GUI_16BITTASK- Windows XP: Represents the thread's application type. This bit is set if the thread corresponds to a 16-bit application.
GUI_CARETBLINKING- Represents the caret's blink state. This bit is set if the caret is visible.
GUI_INMENUMODE- Represents the thread's menu state. This bit is set if the thread is in menu mode.
GUI_INMOVESIZE- Represents the thread's move state. This bit is set if the thread is in a move or size loop.
GUI_POPUPMENUMODE- Represents the thread's pop-up menu state. This bit is set if the thread has an active pop-up menu.
