[Qt-interest] Cursor line sticks in QLineEdit

  I wrote to the list back in March/April about
  essentially the same problem using QSpinBoxes
  (which programmatically change the included
  QLineEdit). Here was my last post to the list
  but you can find the entire discussion in the
  archives.

  Essentially, this isn't well-handled in Qt (at
  least as recently as Qt 4.7.x) and cursor-hiding
  seems to require setting the LineEdit to be read-
  only, something you may not want to do. (It was
  okay for our touchscreen spinboxes.)

Re: [Qt-interest] How do I turn-off/hide the text cursor in QSpinBox?

All:

  Thanks for all the help, everyone!

  As it turns out, to work-around various other
  limitations in the Q(Abstract)SpinBox implementation
  when it's used on touch-screens, we already did have
  QSpinBox subclassed and had already been assigning
  a new QLineEdit to the subclass.

  So by Friday afternoon, I was doing exactly what has
  been suggested and attempting to set just the QLineEdit
  to "Read Only". Done in the QSpinBox constructor (after
  we've done the setLineEdit() to substitute our own
  QLineEdit instance), this didn't work; some initialization
  farther down the road clears the Read-Only status.

  Today, I took a big hammer and simply re-asserted the
  Read-Only status with every step taken by the spin-box:

    lineEdit()->setReadOnly(true);


  That works.

  But when I look at all the work we've done to make
  spin boxes work for us (in our touch screen environment),
  I'm pretty sure we'd have been better-off if we hadn't
  used Q(Abstract)SpinBox at all and simply used two of
  our "Sound-making pushbuttons" and a QLabel to display
  the results.

  There really needs to be a simple class for Spinboxes
  on touchscreens that doesn't carry all the burdens of
  this QLineEdit-based class.
