This most likely isn't the most elegant solution, but I managed to do what
I needed using something similar to the following:
In the buttonrelease-1 table binding, I set a global variable
tblcell_active = 1. This acts as a flag to tell me if there is an active
cell. Next (still within the binding...) I show a 'dialog' that the user
can select from a set of preset values. Once the user has made their
selection, I then set these values in cells elswhere in the table. When
the user closes the dialog (clicks the OK button), a procedure is called
where I have something like the following:
if {$tblcell_active} { ;# the user has clicked on a cell...
set cur_tbl_row [mytablealias index active row] ;# get the row index of
the cell
set tblcell_active 0 ;# reset the flag
}
:
:
# place the user selected values in cells in the same row, but different
columns...
set mytablearray($cur_tbl_row,$column1) $variable1
set mytablearray($cur_tbl_row,$column2) $variable2
Many thanks!
