Titanium.UI

moduleAndroidiPhoneiPadmacOSsince 0.4

Extends Titanium.ModuleTitanium.Proxy

The main Titanium.UI module.

The UI module is responsible for native user-interface components and interaction inside Titanium. The goal of the UI module is to provide a native experience along with native performance by compiling Javascript code into their native counterparts as part of the build process.

Design

The UI module is broken down into 3 major area:

  • Views - Views are containers that host visual elements such as controls or other views. Views can have their properties customized, such as their border color and radius, can fire events such as swipe events or touches, and can optionally contain a hierarchy or other views as children. In Titanium, most views are specialized to perform both a visual function and set of interaction behaviors such as Table View or Coverflow View. Views are always named with the suffix View.

  • Controls - controls, or sometimes referred as widgets, are visual elements such as sliders, buttons and switches. They provide a visual element which has a defined behavior and typical have special configuration and special events. Controls themselves are views and also inherit a views properties, functions and events.

  • Windows - Windows are typically top-level visual constructs that are the main part of your interface. An application will always have at least one window and windows can take different shapes and sizes, can have display and interaction properties such as fullscreen or modal and can be customized, such as changing their opacity or background color. Windows themselves are views and also inherit a views properties, functions and events. There are a few specialization of Windows such as a Tab Group which offer additional behavior beyond the basic Window. It is considered a best practice to use a NavigationWindow as the root of your application.

Titanium uses the Factory Pattern for constructing objects and a general naming pattern for APIs. For example, to construct a Alert Dialog, you call the method Titanium.UI.createAlertDialog. To create a TextArea, you call the method Titanium.UI.createTextArea. Once an object is created, it will be available until it goes out of scope.

Optimizations

UI objects are optimized by Titanium to not be realized into the drawing context and placed into the device UI surface until needed. That means that you can create UI objects, set their properties and add them to their hierarchy without much worry about memory or performance. When the native drawing surface needs to render a specific view or control, Titanium will automatically create the view as needed. Additionally, Titanium is optimized to also release memory once the view is no longer needed, on screen or in low memory situations. However, it's a good idea to help Titanium along in certain cases where you are no longer using objects. For example, you should call close on a Window instance when you are no longer using it. You can safely call open on the window again to re-open it.

Global Context

Prior to the release of Titanium SDK 9.0.0.GA any variable declared in app.js or alloy.js was added to a global scope. This however is no longer the case since 9.0.0.GA. However it is still possible to add variables to a global scope by adding global. in front of any variable declared in app.js or alloy.js. However you should be careful with adding variables to global context because anything added to the global context will not be garbage-collected.

In Alloy the recommended way to add global context is Alloy.Globals.

Portability

Titanium components are designed to be portable across as many platforms as it supports. However, there are cases where a device either does not support a specific feature or capability or where it support additional functionality. For cases where the device OS supports capabilities that other platforms do not, we attempt to place those capabilities in a separate namespace, such as Titanium.UI.iOS. However, in cases where the control is in a common namespace and support additional features, we continue to place that functionality directly on the object.

Events

Event listeners must be defined before their respective events are likely to be fired, otherwise they are not guaranteed to be called. The open and focus Window event listeners, for instance, must be defined before the window is opened.

Evaluating events as late as possible while bearing the above consideration in mind, however, can significantly improve application responsiveness. For example, an event listener for a click event may be defined after the parent window has been opened.

Adding eventListeners in Alloy makes sure they are bound before they are fired.

Colors

Many UI components have properties that control their color.

Colors may be specified as a hex triplet to determine the red, green and blue channels. Thus, '#000000' is specified for black, '#ff0000' for red, '#00ff00' for green, '#0000ff' for blue, and '#ffffff' for white, etc. A channel may be abbreviated when its two hex digits are identical, such as '#000', '#f00', '#0f0#', '#00f' and '#fff' for the above colors, respectively.

An additional alpha channel is supported as a prefix to the hex triplet (ARGB or AARRGGBB). So, to make the purple-like color '#ff00ff' semi-opaque, you could use an alpha value of '55', giving, '#55ff00ff' or '#5f0f'. Please note that both iOS and Android use ARGB format, while typical CSS supports RGBA.

Note that while the pound symbol, #, is not mandatory on iOS when using the hex triplet format, it is recommended to include it to provide compatibility with other platforms.

iOS and Android also accept colors specified in the form, rgb(R,G,B) and rgba(R,G,B,A), with the color channels inside the parentheses represented by integer numbers between 0 and 255 and the alpha channel by a float number between 0 and 1.0 (transparent to opaque, respectively). For example, an opaque purple could be obtained using 'rgb(255,0,255)' and a semi-opaque purple using 'rgba(255,0,255,0.3)'. Note that although this format will work if the rgb or rgba prefix is omitted, this is not officially supported and thus not recommended.

Alternatively, the following set of color names are recognized.

'aqua', 'black', 'blue', 'brown', 'cyan', 'darkgray', 'fuchsia', 'gray', 'green', 'lightgray', 'lime', 'magenta', 'maroon', 'navy', 'olive', 'orange', 'pink', 'purple', 'red', 'silver', 'teal', 'white', 'yellow'.

All color properties also accept a value of 'transparent'.

On Android, if you want to create a semi-transparent window, set the opacity property before opening the window.

On iOS, you can set a global tinting using Titanium.UI.tintColor. All child views will inherit the tint color by default and are able to override the color using tintColor on their own views. The default tintColor on iOS is the blue (system-color).

If a color property is undefined, the default color of the particular UI element is applied. If a color value is not valid on iOS, the default color is applied, whereas, on Android, the color yellow is applied.

On iOS, you may use named system colors. See the Titanium.UI.Color documentation for more details.

Dark Mode

In iOS 13 Apple introduced support for users to adopt a system-wide Dark Mode setting where the screens, view, menus, and controls use a darker color palette. You can read more about this in the Apple Human Interface Guidelines.

There are two aspects to dark mode that can be specified for your app, colors and images.

Specifying Dark Mode colors

To specify colors for dark mode, also known as semantic colors, first create a file called semantic.colors.json in the Resources directory for classic applications, or in the assets directory for Alloy applications. Then you can specify color names in the following format:

  {
    "textColor": { // the name for your color
      "dark": {
        "color": "#ff85e2", // hex color code to be set
        "alpha": "50" // can be set from a range of 0.0-100.0, integer or float
      },
      "light": "#ff1f1f" // can be a hex color (with alpha via ARGB/AARRGGBB)
    }
  }

To reference these colors in your application use the Titanium.UI.fetchSemanticColor API, this is a cross platform API that on iOS 13 and above will use the native method that checks the users system-wide setting, and in all other instances will check the Titanium.UI.semanticColorType property and return the correct color for the current setting.

You may also directly use the named of the colors as values to any color properties on UI elements.

Specifying Dark Mode images

Note: Dark Mode images are iOS only.

To specify dark mode images, use the -dark suffix on the image name. When building your app the images are set as the dark mode variant, then refer to images as normal and iOS will select the correct image dependent on the users system-wide setting.

For example given an image logo.png with @2x and @3x variants, the following dark mode images should exist:

  • logo-dark.png
  • logo-dark@2x.png
  • logo-dark@3x.png

And you would reference the image as before using logo-dark.png

Android: You can use the native app/assets/android/images/res-night folder (extend them with e.g. res-night-xxhdpi if needed) for dark-mode images.
