MINMAXINFO structure (winuser.h)

Contains information about a window's maximized size and position and its minimum and maximum tracking size.

Syntax

typedef struct tagMINMAXINFO {
  POINT ptReserved;
  POINT ptMaxSize;
  POINT ptMaxPosition;
  POINT ptMinTrackSize;
  POINT ptMaxTrackSize;
} MINMAXINFO, *PMINMAXINFO, *LPMINMAXINFO;

Members

ptReserved

Type: POINT

Reserved; do not use.

ptMaxSize

Type: POINT

The maximized width (x member) and the maximized height (y member) of the window. For top-level windows, this value is based on the width of the primary monitor.

ptMaxPosition

Type: POINT

The position of the left side of the maximized window (x member) and the position of the top of the maximized window (y member). For top-level windows, this value is based on the position of the primary monitor.

ptMinTrackSize

Type: POINT

The minimum tracking width (x member) and the minimum tracking height (y member) of the window. This value can be obtained programmatically from the system metrics SM_CXMINTRACK and SM_CYMINTRACK (see the GetSystemMetrics function).

ptMaxTrackSize

Type: POINT

The maximum tracking width (x member) and the maximum tracking height (y member) of the window. This value is based on the size of the virtual screen and can be obtained programmatically from the system metrics SM_CXMAXTRACK and SM_CYMAXTRACK (see the GetSystemMetrics function).

Remarks

For systems with multiple monitors, the ptMaxSize and ptMaxPosition members describe the maximized size and position of the window on the primary monitor, even if the window ultimately maximizes onto a secondary monitor. In that case, the window manager adjusts these values to compensate for differences between the primary monitor and the monitor that displays the window. Thus, if the user leaves ptMaxSize untouched, a window on a monitor larger than the primary monitor maximizes to the size of the larger monitor.
