    <p>I'm using GWT 2.4 Drag and Drop API to drag elements for data transfer between widgets. Implementing the Drag and Drop behaviour was straight forward but I'm having problems changing the cursor while dragging an element. I've done a bit of research and I've found a few articles on how I could achieve this.</p> <p>This article <a href="http://blog.vjeux.com/2012/css/css-cross-browser-drag-cursor.html" rel="nofollow noreferrer">http://blog.vjeux.com/2012/css/css-cross-browser-drag-cursor.html</a> suggests that it can be done by setting the <strong>cursor</strong> property to whichever acceptable value we would want. I've tried (<strong>cursor: -webkit-drag; or cursor: move;</strong>) on the element to be dragged or the element where an element can be dropped but only added a small image to the bottom right of the cursor icon.</p> <p>Took a look at this <a href="http://www.html5rocks.com/en/tutorials/dnd/basics/" rel="nofollow noreferrer">http://www.html5rocks.com/en/tutorials/dnd/basics/</a>, it is said that the cursor(effect) can be changed when dragging or dropping by setting <strong>effectAllowed</strong> and <strong>dropEffect</strong> from the <strong>dataTransfer</strong> object. Despite the GWT Drag and Drop API not exposing none of these properties, I can set them through <strong>JSNI</strong> yet the effect was the same as before (with CSS).</p> <p>I've found these questions <a href="https://stackoverflow.com/questions/10119514/html5-drag-drop-change-icon-cursor-while-dragging">HTML5 Drag &amp; Drop Change icon/cursor while dragging</a> and <a href="https://stackoverflow.com/questions/8459838/changing-mouse-cursor-for-html5-drag-drop-files-gmail-drag-drop">Changing Mouse Cursor for HTML5 Drag Drop Files (GMail Drag Drop)</a> on the same subject but none seemed to help to actually change/replace the icon while dragging.</p> <p>Any help is appreciated.</p> <p>Test environment:</p> <p>Ubuntu 12.04.1 Chrome 22</p> <p>Cheers,</p>

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.
