RE: [Tktable] Minimum Column Size Option?

[Martin.Backe@HSC.com]

Jeff,

Regarding tk_tablePasteHandler, the main thing is to offer sample code that
can be commented/uncommented to allow for the desired behavior.

I'm not sure I understand your comment below the cursor discussion (3rd
bullet). I added a little logic to my tkTable.tcl that maintains the arrow
cursor while over title cells.

The version of Excel I use (Office 97) does not allow the left edge of the
right most cell to be positioned BEYOND the table borders. Create a simple
table (pack [table .tb] -fill both -expand true) and drag the left edge of
the right most cell beyond the table's right border. You will observe that
the cell's border cannot now be accessed for resizing. You must increase
the table size to get to this cell again. Excel properly keeps this from
happening. Even though you can't see the cell's edge, you can still grab it
and shrink the cell again. Minor changes are needed (in tkTable.tcl) to
mirror Exel's behavior in this regard.

I'm sending you in a separate e-mail my final tkTable.tcl file that
implements the title cell paste (which you've already incorporated), the
title cell cursor, the minimum cell width (my application doesn't allow row
height changes, so the tkTable.tcl would require further changes to handle
minimum heights), and cell resize limiting (beyond borders). Perhaps it can
be useful if you still think these ideas have merit.

Aside from the current 0?  :)

Changed to disallow for now.  tk_tablePasteHandler really is
meant for the user to modify though.

Hmmm, yes difficult.  Title cells are inherently anchored and
non-selectable.  Someone else suggested generic "anchorable"
rows or columns, which could make "titles" obsolete, but that
would be an incompatible change.

I modelled this on Windows and Excel, which allows extending the
border off the window...
