>Summary: wxMac: List’s column labels abbreviation broken

Initial Comment:
With wxMac 2.8rc1 has list's column labels abbreviated when the column width gets narrow. However, sometimes the abbreviated labels do not go back to full labels, especially when the labels were abbreviated when the list is initialised.

Okay, I narrowed down what exactly is going on:

- Apparently the non-subclassed table works okay at least as to the
abbreviation is concerned. That's one thing.
- In both subclassed and non-subclassed cases, column width doesn't get
correct width with InsertColumn. ie. m_list->InsertColumn( 0, _("#"),
wxLIST_FORMAT_RIGHT, 25); gives me about 70pixels width.
- In both subclassed and non-subclassed cases, EVT_LIST_COL_END_DRAG in
event table does not give me the column width change as documented. ie.
EVT_LIST_COL_END_DRAG(-1, ImagesList::OnColumnWidthChange) does not call my
OnColumnWidthChange on column width change.
- SetColumnWidth with specific width works.
- SetColumnWidth with wxLIST_AUTOSIZE however, changes the width to the
width same as one with InsertColumn call.

(All above are with wxLC_REPORT mode.)

I'm suspecting the real width that widget keeps and the width that wxMac
keeps internally start mismatching somehow, which maybe resulting in the
wrong abbreviation behaviour. Probably this isn't the same bug as the first
report anymore.

I've filed a new report:

I tried 2.8.4 release, and it seems still not working; if the column
started its life narrow, the label gets abbreviated even when that column
gets widened.

The new experimental build is available here (PPC is against 10.3.9 SDK,
Intel 10.4u SDK):

I've just confirmed it's NOT fixed even with the suggested mod. (I've
compiled the 2.8 release with the suggested modification below.)

The recompiled experimental build is available here:

I'm sorry but I don't really have a time to recompile everything at the
moment.
If it's ok, I will check the progress among other issues when RC2 comes
out.

Thanks

Okay, I figured out how to reproduce this. It happens when an item is
added, as your program calls SetColumnWidth to adjust columns at that time.
Apparently, if the column width is too small when SetColumnWidth is called,
it uses the 'clipped' text as the item's label rather than the full item
label... 

As I don't have any sample code I can debug this with ATM, could you tell
me if adding the following to listctrl_mac.cpp in
wxMacDataBrowserListCtrlControl::wxMacDataBrowserListCtrlControl helps?

SetDataBrowserTableViewGeometry( GetControlRef(), true, false );

You can add it right above this line:

SetDataBrowserCustomCallbacks( GetControlRef(), &callbacks );

Attached.

I compile PPC portion against 10.3.9 SDK, so there might be a difference
beyond the endians.
You can run the PPC portion of the App with Rosette. Just open the
inspector in Finder and see the option.

I don't have a 10.4.8 PPC box, but I do have an Intel box and I don't see
the problem here. Do you have a screen shot?

I'm updating the experimental build here:
http://homepage.mac.com/ippei_ukai/software/hugin/HuginOSX-v061_wx28rc1.zip.zip
And the binary release of the same version which uses wxMac 2.7.0-1 with
some patches found here:
http://downloads.sourceforge.net/hugin/HuginOSX-v061_build2.dmg

The relevant code can be found here:
http://hugin.cvs.sourceforge.net/hugin/hugin/src/hugin/ImagesList.cpp?revision=1.37&view=markup

Sorry for not having a short sample, but if you could play with it and fix
the problem, I'd really appreciate it.
I use Mac OS X 10.4.8 PPC by the way.

I've tried initializing columns with very long names, but when I resize
the column, the label always changes to a full label for me. Could you tell
me more about what OS and architecture (intel or ppc?) you're running?
Also, do you know of any samples that exhibit this problem?
