Floattext.mui Background

        Floattext class is a subclass of list class that takes
        a big text string as input and splits it up into several
        lines to be dislayed. Formatting capabilities include
        paragraphs an justified text with word wrap.



Floattext.mui Attributes

    Attribute                           Ver ISG Type
    ----------------------------------- --- --- --------------------
    MUIA_Floattext_Justify              V4  ISG BOOL
    MUIA_Floattext_SkipChars            V4  IS. STRPTR
    MUIA_Floattext_TabSize              V4  IS. LONG

MUIA_Floattext_Justify


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

    FUNCTION
        Indicate whether you want your the text aligned
        to the left and right border. MUI will try to
        insert spaces between words to reach this goal.

        If you want right aligned or centered text,
        use the MUIA_List_Format attribute.

    SEE ALSO
        MUIA_Floattext_Text, MUIA_List_Format


MUIA_Floattext_SkipChars


    NAME
        MUIA_Floattext_SkipChars -- (V4 ) [IS.], STRPTR

    FUNCTION
        Defines an array of characters that shall be skipped
        when displaying the text. If you e.g. want to
        display a fido message and know it has some CTRL-A
        control characters in it, you could set this
        attrinbute to "\1" to prevent floattext class
        from displaying unreadable crap.

    SEE ALSO
        MUIA_Floattext_Text


MUIA_Floattext_TabSize


    NAME
        MUIA_Floattext_TabSize -- (V4 ) [IS.], LONG

    FUNCTION
        Adjust the tab size for a text. The tab size is measured
        in spaces, so if you plan to use tabs not only at the
        beginning of a paragraph, you should consider using
        the fixed width font.

        Tab size defaults to 8.

        MUIA_Floattext_Text


MUIA_Floattext_Text


    NAME
        MUIA_Floattext_Text -- (V4 ) [ISG], STRPTR

    FUNCTION
        String of characters to be displayed as floattext.
        This string may contain linefeeds to mark the end
        of paragraphs or tab characters for indention.

        MUI will automatically format the text according
        to the width of the floattext object. If a word
        won't fit into the current line, it will be wrapped.

        If you plan to use tabs not only at the beginning
        of a line you should consider using the configured
        fixed width font.

        MUI copies the complete string into a private buffer,
        you won't need to keep your text in memory. If memory
        is low, nothing will be displayed. Thats why you always
        have to be prepared for handling a NULL pointer when
        getting back MUIA_Floattext_Text.

        Setting MUIA_Floattext_Text to NULL means to clear
        the current text.

        Please note that justification and word wrap with
        proportional fonts is a complicated operation and
        may take a considerable amount of time, especially
        with long texts on slow machines.

    EXAMPLE

        char *text = AllocVec(filesize,MEMF_ANY);

        Read(file,text,filesize);

        fto = FloattextObject,
           MUIA_Floattext_Text,text,
           End;

        FreeVec(text);

        /* ... if you need your text later, you can get it   */
        /* with a simple get(fto,MUIA_Floattext_Text,&text); */
