The WINDOWPLACEMENT structure contains information about the placement of a window on the screen.
length
Specifies the length, in bytes, of the structure. (The GetWindowPlacement function returns an error if this member is not specified 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 flags:
Value | Meaning |
WPF_SETMINPOSITION | Specifies that the x- and y-positions of the minimized window may 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 may be one of the following values:
Value | Meaning |
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.
