App Hack: Three – 9-15 Nov

1 BY devrel

In each previous week we’ve used a particular API or technique as the central theme of the hack.  This week I thought it would be fun to do something more open ended.  This means you can use any technology or APIs you want.  It’s entirely up to you how you want to interpret it, so I expect we will have some very creative entries.

The theme this week is “Three”.  That could mean the number three, a book named Three, a trilogy of things, or a game with three legged aliens.  It’s entirely up to you.  Use your imagination to it’s fullest.

App Hack: Multitouch – 2-8 Nov

0 BY devrel

For this week’s app hack we are going to focus on a feature that has always been a passion of mine: multi-touch.  Having the ability to get multiple touch points from the hardware lets you do many interesting things. The most common use is to let the user do an action with multiple fingers, such as a pinch to zoom gesture or a two fingered swipe.  However, there is another use: letting the user do multiple actions at the same time!  Consider a multi-player air hockey game. Each user has a finger on the screen at the same time. While their actions are independent, they are also simultaneous, so we need multi-touch events to make it work.

App Hack : Popup Apps – 26 Oct-1 Nov

1 BY devrel

Editor’s note: This week we are featuring a guest challenge from rockstar webOS developer Doug Reeder. He has pioneered an app interface that he calls Desk Accessories. Your challenge this week is to create an app that uses this kind of interface. Take it away, Doug!

webOS “Desk Accessories” Using Dashboards and System Popups

Background

Psychological research shows that humans cannot efficiently concentrate on more than one activity at a time. However, there are single activities that require two apps on the screen at once. For example, one might want to compose an e-mail while reading figures from a spreadsheet, or calculate price comparisons while shopping on-line.

New tutorial: Using 3rd-party Javascript Libraries in Enyo Apps

0 BY Fred Patton

One benefit of developing for a JavaScript framework like Enyo is being able to take advantage of existing 3rd party JavaScript libraries. Using these add-on libraries allows us to quickly implement tools, controls, and animations to our applications with minimal effort.

If you’ve been wondering how to start using other libraries with Enyo, webOS Developer Relations Engineer Jeremy Thomas has a new tutorial on the Developer Portal just for you. Check it out here.

App Hack : Accelerometer – 19-25 Oct

1 BY devrel

This week’s App Hack will take a look at an API common across all webOS devices: the accelerometer. Generally, it is used to flip the screen around when the user rotates their device, but it can be used for so much more than that.

Accelerometer

The accelerometer can be accessed by listening for two different events: orientation and acceleration. Orientation does the hard work of determining when the user has flipped their device to one of the standard orientations. It also gives you the pitch and roll relative to the current orientation. You can also set the orientation using the setWindowOrientation function. This takes a named orientation of ‘up’, ‘down’, ‘left’, ‘right’, ‘landscape’, ‘portrait’, and ‘free’. The directions like ‘up’ disable rotation and fix the device to one orientation. The ‘landscape’ mode will let the screen flip 180 degrees but always be in wide screen. The portrait mode is similar. And finally ‘free’ will let the user rotate however they choose.
