- renamed XMutableGridDataModel::setRowHeading to updateRowHeading for consistency reasons
- renamed XSortableGridDataModel to XSortableGridData - actually, this is not a full-fledged model in itself.
- introduced XGridColumn.Flexibility, determining to which degree the column is resized during auto-column-resizing
- removed XGridColumn.PreferredWidth - there really is no need for this anymore now
- documented the relationship between XGridColumn.Flexibility and XGridColumn.Resizeable
- re-implemented TableControl_Impl::impl_ni_updateColumnWidths, with (hopefully) less magic
Things missing in the SortableGridData implementation
- add as listener to the delegator, so we're notified of changes
- translate and multiplex those changes
- do own notifications (XGridDataListener.dataChanged) when the sort order changed
- (possibly) update the sort order when the data in the current sort-column changed
fact some clients (the A11Y API implementation) exploited this, e.g. by simply adding elements to the array,
without the owner (the TableControl/_Impl) ever noticing it. Replaced that with a working API.
In this course, removed XGridSelection::getMin/MaxSelectionIndex. Pretty useless IMO, unused, and ugly to
implement.
In this course, more code which was in SVTXGridControl was moved to the places it belongs to, effectively
meaning that the TableControl has better chances than before to be used outside an SVTXGridControl (though
we're not there, yet).
Also, the selection-related methods in TableControl/_Impl got some refactoring love, so the implementation
details are hidden in the Impl class now, instead of being exposed to an exploited by the TableControl.
And while we were there ... The XGridSelection does not provide a |selectColumn| anymore (there was no
preparation whatsoever for column selection, anywhere, thus it was a complete dummy.)
Also, its de/selectRows methods have been removed: They have questionable use, and make implementation
rather difficult, compared with multiple calls to de/selectRow.
having more reasonable defaults for the colors (VOID instead of some hard-coded values, which thus are unusable).
Also, introduced new property UseGridLines controlling whether or not to paint the table grid.
