MUI Autodocs: Prop.mui

Prop.mui Background

Prop class generates the well known proportional gadgets.
It offers the same attributes as a usual boopsi gadget
of propgclass. However, MUI's prop gadgets allow using
any imagery for the knob and for the background.

Prop.mui Methods

    Method                              Ver
    ----------------------------------- ---
    MUIM_Prop_Decrease                  V16 
    MUIM_Prop_Increase                  V16 

MUIA_Prop_Entries

    NAME
        MUIA_Prop_Entries -- (V4 ) [ISG], LONG

    FUNCTION
        Set or get the total number of entries.

    SEE ALSO
        MUIA_Prop_Horiz, MUIA_Prop_Visible, MUIA_Prop_First

MUIA_Prop_First

    NAME
        MUIA_Prop_First -- (V4 ) [ISG], LONG

    FUNCTION
        Set or get the number of the first entry.

    SEE ALSO
        MUIA_Prop_Horiz, MUIA_Prop_Visible, MUIA_Prop_Entries

MUIA_Prop_Horiz

    NAME
        MUIA_Prop_Horiz -- (V4 ) [I.G], BOOL

    FUNCTION
        Determine if you want a horizontal or a vertical
        prop gadget.

        Defaults to FALSE, i.e. vertical.

    SEE ALSO
        MUIA_Prop_Entries, MUIA_Prop_Visible, MUIA_Prop_First

MUIA_Prop_Slider

    NAME
        MUIA_Prop_Slider -- (V4 ) [ISG], BOOL

    FUNCTION
        Indicate that this prop gadget is used in a slider. MUI might
        then use different imagery. Since you really should use the
        slider class when creating sliders, you normally don't need
        to care about this attribute.

MUIA_Prop_UseWinBorder

    NAME
        MUIA_Prop_UseWinBorder -- (V13) [I..], LONG

    SPECIAL INPUTS
        MUIV_Prop_UseWinBorder_None
        MUIV_Prop_UseWinBorder_Left
        MUIV_Prop_UseWinBorder_Right
        MUIV_Prop_UseWinBorder_Bottom

    FUNCTION
        If you set this attribute to one of

        MUIV_Prop_UseWinBorder_Left,
        MUIV_Prop_UseWinBorder_Right,
        MUIV_Prop_UseWinBorder_Bottom,

        some very special magic will take place with this
        proportional gadget. In fact, it will not eat
        any display space at all or render anything, it
        stays invisible in your windows GUI. Instead, the
        gadgets control and display will be linked to one
        of the scrollbars in the window border.

        There is no difference in talking to the object,
        you can use all prop gadget attributes regardless
        whether its a real prop gadget or just a window
        border link. Of course, gadgets in window borders
        will use the intuition look regardless what the
        user has configured.

    NOTES
        You *must* enable border scrollers for the parent window
        with the corresponding attributes (see below)
        before using MUIA_Prop_UseWinBorder.

        Obviously, you can only link exactly one prop gadget
        to one window scroller. Linking more than one gadget
        to the same window scroller will result in big
        confusion.

        To simplify programming, the classes Scrollbar.mui
        and Listview.mui also accept the MUIA_Prop_UseWinBorder
        attribute and pass it on when creating their prop
        gadgets. This allows you to do something like

        WindowObject,
           MUIA_Window_UseRightBorderScroller, TRUE,
           MUIA_Window_RootObject, VGroup,
              Child, ListviewObject,
                 MUIA_Prop_UseWinBorder, MUIV_Prop_UseWinBorder_Right,
                 ...

        to create a listview thats controllable with a scrollbar in
        the right window border.

        Scrollgroup class (for virtual groups) features another
        attribute called MUIA_Scrollgroup_UseWinBorder, TRUE/FALSE
        to allow control of virtual group from window borders.

        Window.mui/MUIA_Window_UseBottomBorderScroller,
        Window.mui/MUIA_Window_UseLeftBorderScroller,
        Window.mui/MUIA_Window_UseRightBorderScroller,
        Scrollgroup.mui/MUIA_Scrollgroup_UseWinBorder

MUIA_Prop_Visible

    NAME
        MUIA_Prop_Visible -- (V4 ) [ISG], LONG

    FUNCTION
        Set or get the number of visible entries.

    SEE ALSO
        MUIA_Prop_Horiz, MUIA_Prop_Entries, MUIA_Prop_First

MUIM_Prop_Decrease

    NAME
        MUIM_Prop_Decrease (V16)

    SYNOPSIS
        DoMethod(obj,MUIM_Prop_Decrease,LONG amount);

    FUNCTION
        This method decreases the value of a proportional gadget by the
        specified amount. Negative values are ok. Range checking is done
        automatically.

    INPUTS
        amount - amount to substract from the gadgets current position.

    SEE ALSO
        MUIM_Prop_Increase, MUIA_Prop_First

MUIM_Prop_Increase

    NAME
        MUIM_Prop_Increase (V16)

    SYNOPSIS
        DoMethod(obj,MUIM_Prop_Increase,LONG amount);

    FUNCTION
        This method increases the value of a proportional gadget by the
        specified amount. Negative values are ok. Range checking is done
        automatically.

    INPUTS
        amount - amount to add to the gadgets current position.
