WM_MDIMAXIMIZE
An
application sends the WM_MDIMAXIMIZE message to a multiple document interface
(MDI) client window to maximize an MDI child window. Windows resizes the child
window to make its client area fill the client window. Windows places the child
window s window menu icon in the rightmost position of the frame
window s menu bar, and places the child window s restore icon in the leftmost
position. Windows also appends the title bar text of the child window to that
of the frame window.
WM_MDIMAXIMIZE
wParam = (WPARAM) (HWND) hwndMax; // handle of child
to maximize
lParam = 0; // not used; must be
zero
Parameters
hwndMax
Value of wParam.
Identifies the MDI child window to be maximized.
Return Values
The return
value is always zero.
Remarks
If an MDI
client window receives any message that changes the activation of its child windows
while the currently active MDI child window is maximized, Windows restores the
active child window and maximizes the newly activated child window.
