Platform Detection for themes

Sencha touch uses a whitelist to detect platforms for themes the same as extjs. the Touch theme feature is also implemented similar to extjs alias t that touch has three schemes, plus the base class, and you can add custom themes. touch themes are. SCSs files
Generated through use of sass. sencha cmd 3.1 installruby and sass for you.

Touch also differs from extjs by its dom structure that enables touch to normalize browser access for its components.

Touch detects the chrome, Safari, and iOS platforms, and loads the touch theme as the default. if you don't specify a theme, touch uses its default theme. touch provides three themes: sencha touch default, ie10, and BlackBerry 10. these themes extend the touch
Base class, which is in the base. SCSs file in the software distribution.

To create a theme, install sencha cmd 3.1 or later on your computer. In Touch, creating a theme means creating a. SCSs file using Sass. You can
Also extend any of the touch themes or the base class.

For more information on creating and using themes, see theming in the extjs documentation.

Note as you add settings to your theme, test their performance using the new showfps feature, which lets you view how theme settings affect animation performance.

The Touch software distribution provides SCSs files for the themes that you can use or change as required. each component has its own CSS file, for example button.css is for buttons and a button. JS file that accompanies use of the component. update a ruby sass
File which generates the CSS file.

Important to use themes, in touch 2.2, you must include the base class base.css file in your app in addition to your theme's CSS file.

Platform config Option

This feature lets you modify configuration options depending on what platform you're using or what theme you're using. an example of how to use this is for scaling graphics between operating system types. for example, for a Mac you may want to use one size
Graphic and on Windows another size.

Performance improvements

The following improvements in sencha touch 2.2 improve performance:

  • Scrolling indicators were refactored and cleaned up to use the fastest indicators for each platform
  • Translatable class logic improved and optimized for each platform
  • Scrollposition has been updated to use a static large size instead of having to dynamically measure, which improves performance for Android 2 and Internet Explorer-this is created as a 1 million-pixel
    <Div> block to ensure any scroll component fits
  • Uniied animation queue that improves performance-use the showfps option feature to measure
    The Performance
  • Updated the list component to improve performance
  • Memory Leak issues for charts and datastore were fixed
  • Chart type renderers apis were unified and cleaned up so that all follow the same pattern. Anyone who created mizmizations for the chart APIs may need to rework their code accordingly
  • Refactored the pulltorefresh plugin for performance and consistency

Measure animation performance with the showfps URL Option

For debug applications, add? Showfps option to the URL to display animation performance information about an application where you enable debugging. The display lists the performance information for the average number
Of animation transitions, the current transition, and the minimum and maximum values for the last 1000 transitions. This feature is very useful for performance testing and creating benchmark data.

Note the showfps feature only works on browsers that support requestanimationframe. If the browser only uses a fallback, a message appears indicating that the results may not be accurate. In this case, the information
Measures how fast JavaScript runs the app, but not how fast the animation draws on the screen. the native Android Browsers Do not support requestanimationframe, but chrome for Android does. in the case of the native Android browsers, the animation sampling
Is based on 60 frames per second; however, this does not necessarily mean the browser is painting the animation at that rate. browsers that do support requestanimationframe means that the showfps feature accurately measures each animation display.

Experimental support

Sencha touch provides support for Firefox 21, which is currently in Alpha. the Mozilla implementation is experimental and relies on the Firefox 21 nightly build of its flexible box implementation. sencha is working with the Mozilla team on known layout issues.
Most examples run, including the kitchen sink, but your mileage may vary. Do not use this for production applications.

User Interface changes

The iconmask option in the button components was removed. In Touch 2.2, icons no longer use masks, they now use the css3 font-face feature.
