Array | Cognitions of FunFun - Our minds can't repel logic of that magnitude!

So I finally got off my lazy butt and at least released one of my projects – my very own WordPress and Simple Machine Forum user registration and login bridge. I just committed the first round of code to the WordPress plugins SVN repository, tagged the first release, and it should show up in the WordPress plugins list any minute now. For those of you who use the plugin, want to contribute, need help, or want to let me know of some bugs – feel free to visit the website, which is conveniently a Redmine project page, here. Don’t go peeking around this WordPress blog trying to find it in action, though, because it isn’t here. It’s actually going to be used for a different WordPress website I’m putting up to manage LAN parties I plan on having in my new houses’ garage – provided we ever close on it, but that’s a different story.

Okay, this one is for all the fellow ActionScript/Flex programmers out there. Have you ever dumped data into a DataGrid or an AdvancedDataGrid only to have your column widths be completely off, or even your row heights be off? Don’t you hate it when the contents of your grid’s cells are cut short? Well here is an easy function that resizes your columns and your grid’s rowHeight so that your data is completely displayed (provided your grid is large enough, of course).

This function takes into account both width and height, and allows you to specify padding for the width and height. It analyzes the measured display height and width of each data cell and assigns the largest values for width to each column, and the largest value for height to the DataGrid/AdvancedDataGrid’s row height. Simply pass it the DataGrid/AdvancedDataGrid you want to optimize width and height for, and the padding values, should you want to put in padding. I call this the xGrid Optimizicator™. Hope it comes in useful!

private function optimizeDataGrid(dg:Object,widthPadding:uint = 0,heightPadding:uint = 0):void

{
for (col = 0; col < dg.columnCount; ++col)
widths[col] = -1;
for each (var item:Object in dg.dataProvider)
{
for (col = 0; col < dg.columnCount; ++col)
{
if (dg is AdvancedDataGrid)
renderer = new AdvancedDataGridItemRenderer();
else
renderer = new DataGridItemRenderer();
dg.addChild(renderer);
dgCol = dg.columns[col];
renderer.text = dgCol.itemToLabel(item);
widths[col] = Math.max(renderer.measuredWidth, widths[col]);
height = Math.max(renderer.measuredHeight, height);
dg.removeChild(renderer);

// Added to take into account header text - thanks modtodd!

dg.addChild(renderer);
renderer.text = dg.columns[col].headerText;
widths[col] = Math.max(renderer.measuredWidth,widths[col]);
dg.removeChild(renderer);

dg.columns[col].width = widths[col] + widthPadding;
}
