| The size of the knob on the scrollbar is inversely proportional
to the total size of the contents to scroll through. This is a
problem for long lists, as the knob becomes uncomfortably small
to use (Fitts' law and all that).
An ability to set a minimum size would be good.
Note that there is code in Fl_Scrollbar.cxx (and maybe other
places) which assumes slider_size has the value set by
Fl_Slider::scrollvalue(), and that code won't work properly
when the slider_size has a different value. An example is
the handling of Page_Up and Page_Down keys, and clicking in
the blank space above or below the knob. | |
