[STR New] Link: http://www.fltk.org/str.php?L2951 Version: 1.4-feature Can't say regarding [1] or [2]. For [3], I'd say google for "double slider widget" and "range slider" and see what you can gather in the way of options. And maybe check out those widget's API to see if they have anything clever. I guess such things can be used for everything from temperature to date ranges. For the latter, it sounds like a app-provided callback could be used to convert numeric values to/from strings such as dates. Options I noticed from doing the above google searches: > a graticule option > drawing an optional box between the tabs > ability to drag the above box (to move both tabs locked together) > option to show text fields above and below the tabs > options for text fields to be editable > options for text fields to include up/down arrows > options for text fields to be integer vs. float > support Fl::scheme("gtk+") (and possibly "plastic") > arrow shaped "tabs" instead of raised rectangles (tinypic link below) > option to show high/low values above or to side of slider at all times (instead of as a tooltip),eg: http://content.w3avenue.com/2009/components/jquery-ui-slider-from-select-element/cover.jpg > data string callback (or virtual method) that lets the app convert numeric values to app defined strings (such as int<->date conversion) Also: this little 'gif video' is neat; a bit over the top with features, but it shows the 'dragging tab lock' mentioned above: http://www.slicer.org/slicerWiki/images/6/6b/VolumesModuleWindowLevelSliderPopup.gif Also: http://dribbble.s3.amazonaws.com/users/58823/screenshots/303390/slider.png http://i48.tinypic.com/2ebsn5i.jpg Regarding [4], yes, I think a min/max for the entire range would be needed, unless you wanted it to be a fixed 0.0 to 1.0 range slider, which might simplify the API, but makes the user's job harder. (Seems the widget should try to support values the app would want, including ints, floats, and perhaps even strings as described above) Of course doing all the above is probably too much, but perhaps it'll give some idea as to how to design the widget so that such features could be provided by the app by its overloading the widget.
