Coding Is Poetry
The GXT Slider is beautiful and fun to use, it can even be passed to a SliderField and used as an input widget in forms (FormPanel), there is however one twist to its API that I think should be looked into in GXT3 and its the fact the you have very little control over the formatting of the tooltip message shown as you drag the slider's thumb back and forth.
It is raining tablets these days, and the situation in Nigeria is no different. The tablet craze is catching on. The portability and the PC-like functionality for the average user make tablets a logical choice for a wide range of people.
The Nigerian market is awash with tablets now, from the iPad/iPad2, Samsung Galaxy Tab, BlackBerry PlayBook, Encipher Inye, to Ovim.
The ToolButton widget from the com.extjs.gxt.ui.client.widget.button package is quite cool, providing a handy mechanism for augmenting a ContentPanel, especially as been used as the "header" component in a GXT Window.
Some months ago the First Public Working Draft of Web Notifications was published. The idea behind this specification is to let web applications integrate with the notification system of the operating system. Or with a third-party system (e.g. Growl on Mac OS X). As there has been some confusion in the past I should stress that this is solely an API for showing a message to the user that e.g. a new email or instant message has arrived. This is not push technology; it is not for streaming data over the network.
The GXT Toolkit provides a Window widget and robust API for creating cool windows. The API allows us to make a window that is draggable but constrained to the browser viewport, thus you can drag the window abitrarily across the screen but none of it's edges will go outside the viewable area of the browser (viewport).
It's been fun building with the new Google Maps V3 API, I'll say RockClimbr is gathering momentum ascending quite well; my only wish was to get it ready for the DevFest follow-up competition. Built with PHP n' MySQL on windows and JQuery 1,4, I thinki it'll turn out to be valueable for it's cause.
The DevFest 2010 Lagos event has come and gone, but we are still brainstorming on some of the ideas still brewing in our minds. With just a fews days (hours actually) before the deadline for the submission of our fully formed "prototypes", I can't help but remember the bug I had during the conference while building my map app.
