WINDOWPLACEMENT Structure

  • 项目

The WINDOWPLACEMENT data structure has the following form:

typedef struct tagWINDOWPLACEMENT {     /* wndpl */
    UINT  length;
    UINT  flags;
    UINT  showCmd;
    POINT ptMinPosition;
    POINT ptMaxPosition;
    RECT  rcNormalPosition;
} WINDOWPLACEMENT;

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

Members

length

Specifies the length, in bytes, of the structure**.**

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 flags:

  • WPF_SETMINPOSITION   Specifies that the x- and y-positions of the minimized window can be specified**.** This flag must be specified if the coordinates are set in the ptMinPosition member.

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

showCmd

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

  • SW_HIDE   Hides the window and passes activation to 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 window that is currently active remains active.

  • SW_SHOWNA   Displays a window in its current state. The window that is currently active remains active.

  • SW_SHOWNOACTIVATE   Displays a window in its most recent size and position. The window that is currently active 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 position of the window’s top-left corner when the window is minimized.

ptMaxPosition

Specifies the position of the window’s top-left corner when the window is maximized.

rcNormalPosition

Specifies the window’s coordinates when the window is in the normal (restored) position.
