It would display a grid which can be scrolled vertically as well as horizontally but during a vertical scroll, the first row will freeze, and during a horizontal scroll, the first column will freeze. How can this be done? I am new to iphone...
In reference to my previous question, I would like to know how to implement a large grid of cells in an iPhone application. I'm working on an interface which would be similar to an Excel spreadsheet, with many rows and columns. Do I have to handle each cell separately? How can I handle user interaction in each cell? Is there a standard...

Whenever I write mouse handling code, the onmousedown/onmouseup/onmousemove model always seemed to force me to produce unnecessarily complex code that would still end up causing all sorts of UI bugs. The main problem which I see even in major pieces of software these days is the "ghost mouse" event where you drag to outside the window ...

I'm a user interface designer. The project I'm working on is a dashboard that will have several interactive and customizable widgets (think Netvibes, etc.).

I saw a couple of similar questions here, but what I'm trying to do is a bit different. I want to have a way to give users some feedback on their actions which can be controlled from both client and server side.

Just googling 'TDD' and 'GWT' easily lead to this article where the author explained how he can test GWT app without container. However, I think his example is not test-driven as he has all the design first and than write the test afterwards, not 'test-first'.

I see movies as a rich vein of design ideas to make our interaction with computers better. I'm sure there are many brilliant examples out there, I've put in some of my favourites, I'd like you to let your imagination and memory run free and feed the wiki. Clearly HAL had a pretty good UI, but it lacks much that we can build on today. ...
I am designing a web application that deals with lots of data. I find it difficult to present this data in a usable, intuitive way. The data has to be sortable/searchable, and the relationships between the data should be obvious (records can have "child items"). Are there any books that specifically deal with this? I am not looking for ...

IE6 & IE7 behavior: clicking on the select reveals the dropdown elements list restricted to 145px...
