JTable - selected row in large table is not "visible"

[Branko Kaucic]

Hi all!

I want to select row in JTable that contains large table (not all rows
can be visible on the screen at once).
I use method

grid.getSelectionModel().setSelectionInterval(i,i);

that selects the row that I wish (row i), but if this row is in
"currently not shown part of table", table data is not scrolled (up or
down) such that just selected row would be visible.
What should I do, because this really bothers me

Regards,
B

This is very Swing dependent, so you may have better luck in either
comp.lang.java.gui
or Sun's own Swing Forum at
http://forums.java.sun.com/forum.jspa?forumID=57

I think what you need to do is:

1. determine the height in pixels of one row in the JTable. There is a
method for this in JTable if I'm not mistaken. 2. calculate the height
in pixels of everything from the top of the table to the row that was
selected - ie rows*height 3. scroll the JScrollPane down (or up as the
case may be) to the selected row

I haven't tested this, but I think it should work. I don't know of an
easier way but there may be one. For that I refer you to the two
references I gave above.

grid.getSelectionModel().setSelectionInterval(i,i)

You just want to make sure those selected rows are as visible as
possible, which might be impossible if the user has selected more than
a screenful.

You might want to simulate how the user would do it, first making the
first row visible then the last.

Keep in mind that your JTable lives in a JScrollPane. Perhaps someone
will come up with a better, way, but you could use
JScrollPane.getVerticalScrollBar().setValue().

use table.scrollRectToVisible(table.getCellRect(row, column, false));
