JTable: resizing all columns as 1 column resizes

Question

I have a JTable with 480 columns inside of a JScrollPane (AUTO_RESIZE_ALL_COLUMNS needs to be off for the JTABLE to display correctly in the JScrollPane). When the user resizes one column I would like the rest of the columns to resize too, so that the column widths of each column are equal.
Thank you in advance,
Brent

Answer 1

[...] I
I have the JScrollPane listening to a histogram of the
balances so the user can click on a month in the
histogram and the JScrollPane (actually JViewport)
will move to display the appropriate column in the
JTable. If the column sizes are not uniform then I
cannot be sure that I'm moving the JViewport to
display the correct JTable column(s).
I thing the GUI is a great design for what must be
done. And thank you for your help and comments.That still sounds pretty klunky. I don't see any user navigating around a 480 column table. They click in your histogram to go to a column, they click somewhere or do keyboard navigation and the display scrolls them a few columns/rows away... they are now lost in a sea of cells and have to go back to the histogram again to try and get back, etc. Having delt with similar situations, there are better ways. Read the last two days dilbert cartoons carefully. :-)
But anyway...
You don't have to have all the columns the same width to make a column visible in the viewport. You can just get the appropriate column's rect by either of these methods:Rectangle r = myTable.getTableHeader().getHeaderRect( col );
Rectangle r = myTable.getCellRect( row, col, true );And then tell the viewport to make sure that rect is visible:myViewport.scrollRectToVisible( r );Much easier than hacking around with custom column resizing logic.
