Row Markers and Highlighting in Version 8 Browse widget
Characteristics of the Updatable browser:
You have the option of row markers, they appear at the left
column of the browser. Upon clicking in the row marker,
this makes the row have focus and selection. A visual
representation of a blue band appears across the row in the
browser. If you click in a cell, then the row still has
focus and selection (the row markeris still depressed) but
you do not get the band. This is because you are now in
update mode.
If you choose NOT to have row markers, then even if the
browser is multi-select, you can only have 1 row at a time
selected. To get the row to have focus and selection, you
click in the cell. You will NOT get a blue band across the
row. But that is the focus and selected row.
Problem: you can never click in a cell that is read-only.
Therefore, you need row-markers.
If it were a TRUE read-only browser, meaning the
definition of the browser NEVER contained the enable
phrase, then upon clicking on any row in the browser, that
row would have focus and selection. You will never get row
markers in a TRUE read-only browse.
The trick of defining a column editable and
then changing it to be read-only is useful only to do
column searching and still have a read-only browser. In
other words, if you make the browse editable and then change
it to read-only immediately so that you can take advantage
of column search, you will get rowmarkers if you
specified them. Pressing a row marker in this situation will
give you the blue bandline. Selecting a column header will
allow you to do a column search but you will not get the
blue band.
