Hi Evtim, I am trying to create a org chart using flex 4 layouts. I basically want to write 1 rectangle at level 0, 2 rectangles at level 1 and 4 rectangles at level 2 and connect them with lines. I want to call the layout twice, once to draw the rectangles and once to draw the lines. How do you know what the x and y coordinates are for components after drawn using the layout.

@Maurice
Yeah, resizing the items to fill in the total width of the row should be possible, you’d need to touch the logic in updateDisplayList() – you already know the total width, then calculate the percentage of each element based on element’s preferredWidth() / sum (all element’s preferred widths) and apply that percentage to the “width” that gets passed in the updateDisplayList() method.

Hi Evtim, I need the flow layout to fill 100% of each row width, possibly enlarging the items that it contains.
Example: suppose the first row contains 3 items of width 100, 200 and 300 (total = 600) and the layout width is 800, then resize the items to 133, 267 and 400, so that the total is now 800.
Same for the other rows.
Is that possible?

What about scroll bars and custom layouts? How difficult are they? Specifically: http://forums.adobe.com/thread/765682?tstart=0

@Arjen Figured it out myself, since is was using a itemrenderer i needed to use "getVirtualElementAt"

Hi,

When i create your example i keep on running into the problem that the “layoutTarget.getElementAt(i);” returns null.

Do you have any idea’s on what i’m doing wrong?

Hi Matthew,
I’d have to see an example of your container arrangement to be able to tell if there’s something wrong or perhaps we have a bug in the SDK
Some issues that we see more often than others:
- make sure to set the 100% on the Scroller itself, and not on the container inside the Scroller.
- make sure that the container doesn’t have some explicit or measured minimum size that will prevent it to shrink below that point. Easiest way is to explicitly set some minWidth=”0″, minHeight=”0″
