[Plib-devel] [PATCH] puSlider/puaScrollBar: more work on optional 'new behavior'

[Melchior F. <mf...@us...>]

Here's another round of patches (or rather: full source files):

puaScrollBar:
- introduce [sg]etLineStepSize (using the slider's step size
  was a bad idea, as sliders also need a line-step (small step)
  if they don't use stepping)

pu.h/puSlider.cxx/puaScrollBar:
- if page-step size is <=0 use the old behavior (default),
  otherwise the new (i.e. do no longer use -1 for that)

puaLargeInput:
- fix a bug in puaLargeInput where increasing the widget width
  moved the text to the right
- make sure added lines scroll the box down if the slider was
  in bottom position
- let font changes also update the geometry
- simplify and optimize the slider autohiding code
- use puaScrollBar also for the bottom scrollbar. The "arrows"
  argument also sets the number of arrow buttons there, whereby
  the former meaning is retained (0, 1, 2 means 0, 1, 2 buttons
  for the vertical scrollbar). The "tens" are used for the bottom
  slider: decimal 12 means: one arrow button on the bottom
  scrollbar, and two on the vertical one.
- setPageStepSize() for both sliders, enabling the new slider
  behavior

puaList:
- setPageStepSize() for the slider, enabling the new behavior
 

The code works well in FlightGear and is valgrind-clean. If
I should run into glitches, then I will, of course, submit fixes.
