Re: progressive table problem with cell events

 Hi Derrell
 
Please find below the original contexts of the message. Sorry for not including it on the first place.

I understand how override _identifyImage method, the only problem is that those cells already have HTML renderer and I need to add cell click events on the top of that. Do you think this can be done?

Hi Monika,

Progressive's Table allows one to create such events in a cell renderer or row renderer but by default it doesn't provide them. To see how/where you'd add such events, look at the boolean cell renderer:
qx.ui.progressive.renderer.table.cell.Boolean, and search for where the allowToggle property is used. You'll see where it creates onclick events to handle the toggling of the icon, which is also were you'd add any events you want generated. The easiest way to do this would be to subclass the cell renderer and override the _identifyImage method.

Cheers,

Derrell

Yes it can be done. When you're working with cell renderers, though, you're working at a very low level. Instead of overriding the _identifyImage method as you'd do if you were extending the Boolean cell renderer, you will extend the Html cell renderer and override the _getCellExtras() method. If you look at the Html cell renderer, you'll see that it does nothing other than extend the Abstract cell renderer. Looking at the Abstract cell renderer, you'll see that it simply creates a div using any style that had been specified by the _getCellStyle() method, and with any extra attributes as provided by the _getCellExtras() method. (Don't be afraid to look at the source of these classes! That's the very best way to learn what's going on and how you can best make use of them.)

When you override the _getCellExtras method, you'll need to catch the DOM's double-click event, in a fashion similar to how the Boolean cell renderer adds an "onclick" event. Since you are extending qooxdoo's functionality here, you need to get your hands dirty; you don't get the benefit of the clean-room (no interaction with the DOM) that ordinary usage of qooxdoo provides. :-)
