Note that before first insert, +units and window size need to be set. Supported units are typographic point +(pt) and millimeters (mm). For SourceUnit, pt, mm and twips are supported. +All scalar numbers in 1/100 of the corresponding unit. + +Line1 is the outer, Line2 the inner line, Distance is the distance between +these two lines. If Line2 == 0, only Line1 will be shown. Defaults for +source and target unit are FieldUnit::POINT. + +SetColor() sets the line color. + +Remarks + +Contrary to a simple ListBox, user-specific data are not supported. +If UpdateMode is disabled, no data should be read, no selections +should be set, and the return code shall be ignore, as in these are +not defined in this mode.

The parameter Fill points to a list +of available font styles for the font. + +Reproduced styles are always added - this could change in future, as +potentially not all applications [Draw,Equation,FontWork] can properly +handle synthetic fonts. On filling, the previous name will be retained +if possible. + +For DontKnow, the FontStyleBox should be filled with OUString(), +so it will contain a list with the default attributes. The currently +shown style probably needs to be reset by the application. + +See also + +FontList; FontNameBox; FontSizeBox; + +-------------------------------------------------------------------------- + +class FontSizeBox + +Description + +Allows selection of font sizes. The values are retrieved via GetValue() +and set via SetValue(). The Fill parameter fills the ListBox with the +available sizes for the passed font. + +All sizes are in 1/10 typographic point (pt). + +The passed FontList must be retained until the next fill call. + +Additionally it supports a relative mod, which allows entering +percentage values. This, eg., can be useful for template dialogs. +This mode can only be enabled, but not disabled again. + +For DontKnow the FontSizeBox should be filled FontMetric(), so it will +contain a list with the standard sizes.
