Re: [flexcoders] Panel and Scrollbars (basic question)
Hi Neil, Sorry, I couldn't actually run this because of the PredefinedEntitiesFromReport data being missing (nothing populated). I see what you are saying about the dynamic sizing, I don't think I can suggest a better way than what you have. If you were to make the layout of the base component absolute it could still be dynamically sized, that would allow you to set constraints for its children which would make the content stretch to the appropriate width. The component should still stretch to whatever size you pass to it. Unfortunately the size would not be determined by its children. Oh well, sorry I couldn't be of more help!

Re: [flexcoders] Panel and Scrollbars (basic question)
Hi Rachel, the panel will be used to populate a modal pop-up window. It's currently not absolute or constrained. The content is dynamic and so I never know exactly what the width of the CheckBox labels or "lbl" text will be - therefore I don't want absolute values used for the width. The Panel should pretty much be able to handle what is thrown at it. I could simply listen for a scroll event and add/subtract 16 pixels to the width of the box depending on whether my content scrolls or not, but I was just guessing that this kind of resizing was a such a common task that there would be some in-built way of handling it.

If you can post code I'd be happy to take a look, I've done a lot of tweaking layouts with lots of scrollbars lately!

Re: [flexcoders] Panel and Scrollbars (basic question)
This may or may not be the answer you are looking for... but is the content of your panel laid out using constraints or absolute values? If you do it with constraints, then your content should get resized when the scrollbar appears. Then again, this may be the inverse of what you are trying to do, and it may cause labels or text to get truncated. Is there a reason that you cannot make the panel wide enough to accomodate your content and scroll bar both, then if the scroll bar doesn't show up then it will just be a little more padding to the right.

Inside it is a Text component, and a Repeater underneath that (...repeating a CheckBox) . All works fine. I want to set the "maxHeight" of the Panel to 200px, so that if I get too many Checkboxes appearing, my content will scroll vertically. When I set maxHeight, I get *both* horizontal and vertical scrollbars appearing - the horizontal scrollbar only appears because the width of the vertical scrollbar eats in to the Panel width - therefore I get horizontal scrolling of about 16 pixels. If I set horizontalScrollbarPolicy to false then my content is still clipped. I'm sure I can muster a workaround easily enough (e.g. manually resize Panel based on ScrollEvent etc), but I thought there surely must be something in-built and neater, already in place to deal with this kind of scenario? Any help much appreciated.
