    <p>My question is: how do I redraw a shape using only code?</p> <p>Short comment on the task itself. I've an eventListener, which grabs clicks on stage and stage resizes. Both execute the same function - <code>redrawEvents(evt:Event)</code>. The stage contains a number of blocks, which represent certain events. On each redraw these blocks are repositioned, and also lines (which represent connections between events) are drawn.</p> <p>I've figured out a way to reposition all the blocks, but I got stuck on redrawing lines.</p> <p>I'm using a single shape to hold all the lines, because lines, unlike blocks, are not interactive. Since the whole point of the application is creating sets of interconnected events, I have to modify this shape every time a new block is created, which also calls redraw function. </p> <p>Here's the code I use to modify the shape</p> <pre><code>stage.addEventListener(MouseEvent.CLICK,redrawEvents); function redrawEvents (evt:Event) { var lines:Shape = new Shape(); lines.graphics.lineStyle(2, 0xFFFFFF, .75); lines.graphics.clear(); for (var k:int = 0; k &lt; connections.length; k++){ lines.graphics.moveTo(eventList[connections[k][0]].x + 50, eventList[connections[k][0]].y + 50); lines.graphics.lineTo(eventList[connections[k][1]].x + 50, eventList[connections[k][1]].y + 50); } addChild(lines); } </code></pre> <p>However, whenever the shape is modified, it still leaves the 'older versions' of itself on screen, and i don't want that. I tried to create and delete instances, varions type conversions, but still that haven't solved the problem.</p> <p>Thanks in advance</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.
