    <p>I'm tying to figure out how I can customize the Eclipse code formatter to break lines more to my liking. I'm trying to set the style for parameter lists, either in method declarations or calls. Looking for a mix of <code>Wrap where necessary</code> and <code>Wrap all elements, every element on a new line</code>. I want to <code>Wrap where necessary, every element on a new line</code>, which doesn't seem to exist. My logic is that no break is necessary for short lines, my eye can scan the parameter list horizontally:</p> <pre><code>public void myMethod(int p1, int p2, int p3) { </code></pre> <p>But for lists that do need to be broken, I would like every element on a new line, so I can scan vertically:</p> <pre><code>public void myMethodWithALotOfParams( ReallyLongClassName param1, AnotherLongName aLongParamName, int p3) { </code></pre> <p>I can't seem to make this happen. I can wrap everything, including short lists. I can wrap only long lines, and continue stacking parameters on each line until I reach the margin. I can't trigger wrapping on long lines, then put each parameter on its own line.</p> <p>This style can be seen in several places in Code Complete (2nd Ed).</p> <p>UPDATE >></p> <p>I don't think there is anything built in to Eclipse to handle this, but I'm not afraid to write code. :) Eclipse is open source, so I tried to find the code that handles formatting, in hopes of building in the preferred behavior. Didn't have much luck on the first try, lots of abstraction, not much parsing and formatting. Hints?</p>

    1. COI don't think it is possible either, but you can at least say to eclipse that self inserted line breaks stay where they are. Personally I do always group related arguments together : bad example, inBuffer, inOffset, inLength (you should use a ByteBuffer instead of course, which contains all three arguments).

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
