Re: [platform-swt-dev] TableColumn issues

[Steve Northover <Steve_Northover@xxxxxxxxxx>]

Milos,

Some of these bugs have not been fixed
because the platforms simply don't do it (or better, we couldn't figure
out how to convince them).  For example, on the Mac, you can't see
mouse down in a table column header.  It just won't tell you. The
column ordering bug reports contained patches for most of the platforms
that showed the functionality was available on all platforms, even if the
exact code from the patches was not complete and was not used in the implementation.
 So, dig in!  Another way to help is to show us a native control
in some other application that does what you want.  That helps us
see that it is possible and shames us into working on it.

If you stop to think about it, we support
5 different operating systems using totally different code bases and somehow
knit together and implement a portable API to all of them and we do this
for free.  It's a full time job, 24-7.  Any help you can give
us is most welcome.

Subject	[platform-swt-dev] TableColumn issues

Hi,
 
We are using SWT Table in our application
for large data view / entry. While the table itself seems pretty ok so
far (using via TableViewer including the new M5 ILazyContentProvider),
the column headers (TableColumn) seems to be really weak. I searched bugzilla
and found couple of quite dated items:
 
https://bugs.eclipse.org/bugs/show_bug.cgi?id=4572
 tooltips in table columns (since 2001-10-11)
https://bugs.eclipse.org/bugs/show_bug.cgi?id=23103
TableColumn doesnt support popup menus (since 2002-09-03)
https://bugs.eclipse.org/bugs/show_bug.cgi?id=32322
TableColumn not firing mouse click events (since 2003-02-20)
https://bugs.eclipse.org/bugs/show_bug.cgi?id=17871
TableColumn does not send MouseHover and MouseMove events (since 2002-05-26)
 
The question #1 is what is planned for
3.1? (the last two items are quite essential – the rest we could in worst
case do ourselves)
 
What I somehow do not understand why a basic
event management (2 last items) is not implemented, while column drag and
drop has been done in M5 (which is more a sugar coating) and column reordering
could be done even before (we anyway use dedicated dialog to reorder /
hide columns to make it user friendly for 30+ columns). Is there an issue
in implementing it on all platforms? ( and we should then rather forget
about these features altogether )
 
If the answer is not sure in 3.1 (wontfix),
would you have suggestion what kind of workaround we could do on TableColumn
in order still use at least the Table itself?
What we need:
A. Tooltip for long column names (critical
unless we B is possible)
B. Set height of the TableColumn so that
we can render multi-line text (header only) – we can somehow live without
if at least the tooltip (mouse event) is there. Would this be ever possible
or not supported by native widgets at all?
C. Popup menu 
 
Is there a workaround for getting mouse
events on TableColumn?
 - We briefly checked that a transparent
canvas over the header (getting the events) seems not supported.
 
Or in the worst case would there be a
somehow “reasonable” way to write custom “TableColumn” (compsite of
canvases + sashes) ourselves that would drive the table widths via hidden
current TableColumn? (and have total control)
 
Thanks for your time.
