RE: [flexcoders] Re: Dynamically adding components to a panel?

Anatole,

 

It looks like I chose the wrong base class.  OH, well.  I thought I saw in the docs that TileList DID support variableRowHeight.

 

Do you happen to know which classes DO actually support variable Row Height? All I need is a list type class that I can put a customer itemrenderer into, so I THINK I can use ANY tree,List,Grid,etc.

 

Thanks in advance.

 

 

Steve

Steve,

You are out of luck - here is snippet from TileBase code (line 50):

/**
 *  The TileBase class is the base class for controls
 *  that display data items in a sequence of rows and columns.
 *  TileBase-derived classes ignore the <code>variableRowHeight</code>
 *  and <code>wordWrap</code> properties inherited from their parent class.
 *  All items in a TileList are the same width and height.
 *
 *  <p>This class is not used directly in applications.</p>
 */

 

You have to choices - try to put it in control that supports variableRowHeight or roll out the new TileBase specific to your project. In later case you merge code in TileBase and DataGridBase makeRowsAndColumns method. I have not tried direct subclassing of TileBase - from the look of it it might be possible.

Regards,

Anatole

Anatole,

 

THANKS VERY MUCH!  I had a feeling that the answer was related to ItemRenderer, but I couldn't seem to get my first steps to work.

 

May I ask one follow up question?  I need to insert the item renders in such a way that my list (inthis case, a TileList) can support different Row Heights for each row.  How can I do this?  No matter what I've tried, all of the rows come out the same height.

 

Thanks in advance,

 

 

Steve

You can do anything there - the simpliest way would be to use runtime styling

I have a similar question. I need to put WRAPPED TEXT into the cells of a
List or Tree.

Is it possible to AddChild to a LIST so that there's an actual UIComponent
as a cell's graphics?

Best Regards,

Steve

Thank you all - I was missing the addChild() concept. Works like a charm.
