Re: [Tora-develop] multi-line table cells in TOra query results?

[Tomas S. <tom...@gm...>]

Hello

  Getting back to this year old question.

2010-01-20 Neulinger, Nathan:
> Is it possible to allow multiline results to expand the height of a cell

  Apparently Qt works this way:
  1. QTableView::sizeHintForRow calculates what width of a row should
be (automatic calculation seems OK).
  2. ONLY if QTableView resizeRowsToContents(); is called (and only
then) that Height value is actually used.

  Now there is toResultTableView::sizeHintForRow defined which always
returns 5 (while automatically calculated value by Qt on my
environment for one row is 15, two rows - 30 etc.).
  resizeRowsToContents is NOT called in
toResultTableView::applyColumnRules so that sizeHint is not used.

  Therefore questions:
  1. Do we really need this toResultTableView::sizeHintForRow
returning 5? Default Qt procedure calculates row height correctly and
TOra does work OK with that method commented out. But maybe it is
actually used somewhere? Code scan finds resizeRowsToContents only in
tostorage.cpp, but I do not see any ill effects in Storage tool with
automatic height calculation enabled.

  2. How should this vertical expansion implemented? For worksheet
only? What about schema browser? What about all other results?
(Easiest way is to enable it everywhere when checkbox in preferences
is set).

  3. Option(s) should be added to control row expansion in ...?
