tablelist cell edit and selection

[Juge]

I am implementing an edit feature to my table where I select multiple rows and
edit a cell on one of them. Afterwards I want to have the edited values on all of the same cells (column) of the other selected rows.

I get it more or less working, however, I have couple of small glitches where I am not sure I can configure it away.

Firstly, when I select multiple rows with selecttype being extended, after clicking on the editable cell, I loose the selection.

Also for a full editable table I would rather start the editing only after double click on the edit cell, but I get an immediate editwindow, this is sometimes a little bit irritating, particularly when I do not wish to edit the cells I would only like to select the rows.

Is there a way to configure this behaviour somehow?

Ok, I was able to achieve something with binds.
I made cells -editable 0

and then:
set InputbodyTag [$mytbl bodytag]
bind $InputbodyTag <Double-B1-ButtonRelease> [list StartEdit %W %x %y]

and with:
proc StartEdit {w x y} {
foreach {tbl x y} [tablelist::convEventFields $w $x $y] {}
set col [lindex [split [$tbl containingcell $x $y] ","] 1]
set row [lindex [split [$tbl containingcell $x $y] ","] 0]
$tbl cellconfigure $row,$col -editable 1
$tbl editcell $row,$col
}

and editendcommand:
proc EditValidate {tbl row col text} {
$tbl cellconfigure $row,$col -editable 0
if {[llength [$tbl curselection]] > 1} {
foreach row [$tbl curselection] {
$tbl cellconfigure $row,$col -text $text
}
}
return $text
}

additionally I needed the -forceeditendcommand 1 in the table definition.
The only remaining problem is that the first click of the double-click influences the selection and deselects the multi-selection. I can influence this by using CTRL simultaneously with double click...
