WINDOWPLACEMENT

The WINDOWPLACEMENT structure contains information about the placement of a window on the screen.

typedef struct _WINDOWPLACEMENT { // wndpl

UINT length;

UINT flags;

UINT showCmd;

POINT ptMinPosition;

POINT ptMaxPosition;

RECT rcNormalPosition;

} WINDOWPLACEMENT;

Members

length

Specifies the length, in bytes, of the structure. Before calling the GetWindowPlacement or SetWindowPlacement functions, set this member to sizeof(WINDOWPLACEMENT).

GetWindowPlacement and SetWindowPlacement fail if this member is not set correctly.

flags

Specifies flags that control the position of the minimized window and the method by which the window is restored. This member can be one or both of the following values:

Value

Meaning

WPF_RESTORETOMAXIMIZED

Specifies that the restored window will be maximized, regardless of whether it was maximized before it was minimized. This setting is only valid the next time the window is restored. It does not change the default restoration behavior. This flag is only valid when the SW_SHOWMINIMIZED value is specified for the showCmd member.

WPF_SETMINPOSITION

Specifies that the coordinates of the minimized window may be specified. This flag must be specified if the coordinates are set in the ptMinPosition member.

showCmd

Specifies the current show state of the window. This member can be one of the following values:

Value	Meaning
SW_HIDE	Hides the window and activates another window.
SW_MINIMIZE	Minimizes the specified window and activates the top-level window in the system's list.
SW_RESTORE	Activates and displays a window. If the window is minimized or maximized, Windows restores it to its original size and position (same as SW_SHOWNORMAL).
SW_SHOW	Activates a window and displays it in its current size and position.
SW_SHOWMAXIMIZED	Activates a window and displays it as a maximized window.
SW_SHOWMINIMIZED	Activates a window and displays it as an icon.
SW_SHOWMINNOACTIVE	Displays a window as an icon. The active window remains active.
SW_SHOWNA	Displays a window in its current state. The active window remains active.
SW_SHOWNOACTIVATE	Displays a window in its most recent size and position. The active window remains active.
SW_SHOWNORMAL	Activates and displays a window. If the window is minimized or maximized, Windows restores it to its original size and position (same as SW_RESTORE).

ptMinPosition

Specifies the coordinates of the window's upper-left corner when the window is minimized.

ptMaxPosition

Specifies the coordinates of the window's upper-left corner when the window is maximized.

rcNormalPosition

Specifies the window's coordinates when the window is in the restored position.
