    Question Get Window Zorder?

    Hi, all

    How can I get a window’s current view placement order (also called “Zorder”)? And is it possible to enumerate from the absolute top window to the last? So that the first window you get has the highest Zorder.

    Use the GetTopWindow/GetNextWindow functions; from MSDN:

    The Z order of a window indicates the window's position in a stack of overlapping windows. This window stack is oriented along an imaginary axis, the z-axis, extending outward from the screen. The window at the top of the Z order overlaps all other windows. The window at the bottom of the Z order is overlapped by all other windows.

    The system maintains the Z order in a single list. It adds windows to the Z order based on whether they are topmost windows, top-level windows, or child windows. A topmost window overlaps all other non-topmost windows, regardless of whether it is the active or foreground window. A topmost window has the WS_EX_TOPMOST style. All topmost windows appear in the Z order before any non-topmost windows. A child window is grouped with its parent in Z order.

    When an application creates a window, the system puts it at the top of the Z order for windows of the same type. You can use the BringWindowToTop function to bring a window to the top of the Z order for windows of the same type. You can rearrange the Z order by using the SetWindowPos and DeferWindowPos functions.

    The user changes the Z order by activating a different window. The system positions the active window at the top of the Z order for windows of the same type. When a window comes to the top of Z order, so do its child windows. You can use the GetTopWindow function to search all child windows of a parent window and return a handle to the child window that is highest in Z order. The GetNextWindow function retrieves a handle to the next or previous window in Z order.
