Release Notes

Highlights - Cascades beta 1

The UI structure and layout highlight.

UI structure and layout

Layout in modern mobile UI frameworks is a science. In this release, you will see our take on it. While we only support the most basic layouts (Stack, Dock, Absolute) at the moment, we have an architecture that allows you to create easy to use, scalable UIs. The layouts support features like padding, margins, weights, and sizing policies to make sure your UIs are scalable.

The Animations highlight.

Animations

Cascades supports implicit and explicit animations. Implicit animations make it easy for you to build a dynamic and stylish UI, without having to spend too much time fine-tuning animations. You can still fine-tune your animations using the explicit animation APIs.

The core UI highlight.

Core UI

A rich set of UI controls encapsulating built-in design and the smart look of BlackBerry. A mix of simple and generic controls together with powerful, high-level controls such as the ActionBar makes it easier than ever to implement a great application structure using tabs and drill-down navigation.

The WebView highlight.

WebView

You can use the WebView component to show HTML 5 content inline with Cascades UI controls. Bring the web to users of your app, while still creating a UI and user experience that's uniquely yours.

The Cascades Builder highlight.

Cascades Builder

Cascades Builder extend the QNX Momentics IDE and provides a streamlined, powerful development environment for creating and deploying Cascades applications. You can use the Cascades Builder project wizard and the built-in templates, or create a project based on any of the bundled samples. You can create the application UI declaratively in QML using the QML source editor. In addition to test driving the UI on a device, you can take advantage of the UI preview. The UI preview renders the QML file displayed in your editor.

The Cascades Exporter highlight.

Cascades Exporter plug-in for Adobe Photoshop

The Cascades Exporter cuts and rescales graphics automatically, which can save designers a lot of time. When exporting a UI design from Photoshop, the plug-in creates a bundle with images and the corresponding layout information. You can import this set of assets as QML and images into Cascades Builder.

Features

Cascades UI framework

All functionality is available as Qt based APIs and declarative components in QML.

Built-in controls

  • Activity indicator - An activity indicator is typically used when the amount of time a process takes can't be determined. The activity indicator is available in three different sizes.
  • Progress indicator - A progress indicator is typically used when the amount of time a process takes can be determined and the process is long enough to display the remaining time to the user.
  • Drop-down menu - A drop-down menu allows users to select an option from a list of options. An option in a drop-down menu can have an optional image and up to two text strings.
  • Date and time picker - A date and time picker allows users to select a date and time. You can set different increments for the range of minutes, and you can set minimum and maximum values for the range (values outside the range will be grayed out). If an invalid value is selected, the picker moves back to the nearest valid value.
  • Radio group - This control is used to present a list of options where only one option in the list can be selected at a time. Each option in the radio group can have text, a description, and an image.
  • Action bar - The action bar is located at the bottom of the screen and can contain actions, tabs, or both. The action bar supports an overflow menu, which is shown from the right, and can be populated with actions. It also supports a sidebar menu, which is shown from the left, and can be populated with tabs. You can define which items you want to display and which menu they should be placed in.
  • CrossCut menu - This control is a context-sensitive menu that is displayed when users press and hold an item in your application. The menu contains actions that are relevant for the pressed item, and is shown from the right. You can choose between pinned mode (which just shows the icons for the actions) and fully extracted mode (which lists all actions that are relevant for the pressed item).
  • Navigation pane - A navigation pane allows users to navigate between different pages, or screens, in your application. The navigation pane acts as a stack, and you can push screens on to the stack to display them or pop them off of the stack to hide them.
  • Foreign window - You can create native QNX windows and render those in a Cascades context. This version support windows that are placed at an absolute position with respect to other Cascades UI components.
  • Segmented control - A segmented control is used to filter between different aspects of the content in a view. This basic version supports labels, but not images.
  • Button - This control represents a button that users can click. You can choose from three different appearances: a button with a string, a button with an image, and a combination where both an image and a string can be added to the button.
  • Check box - You can use a check box to present options where the selection is not exclusive and multiple options may be selected simultaneously.
  • Container - A container is typically used as a wrapper for creating a larger layout and also for creating custom controls. Containers support scrolling vertically and horizontally together with rubber band and bounce effects.
  • Divider - A divider can be used when you want to divide or separate items visually within a list.
  • Label - A label is a simple block of text that is non-selectable. You can change the font color, format, and font style of the label.
  • ImageView - This component is used to display images. Images can be scaled using fill method, aspect fit, or aspect fill.
  • Slider - A slider is used for setting values within a defined range, allowing users to change values by dragging the slider left and right.
  • TextArea - A text area shows both single and multi-line text. The text area can be editable to allow users to type text.
  • TextField - A text field is a single, editable line of text, with or without a border.
  • Toggle button - A toggle button is used to represent options that have only two states: on or off.

Custom controls

  • If you don't find what you're looking for in the set of core UI controls, you can create your own controls by combining (or compositing) existing controls. This gives you unprecedented flexibility when designing your UIs.

Text styling

  • You can use the text styling API to customize the look of text-based controls in your apps. Use this API to specify visual properties such as formatting, style, alignment, and size.

Resource management

  • The resource management system in Cascades allows for asynchronous loading of .png and .jpg files, as well as loading images from pixel buffers.

Lists

  • Vertical List - Create an elegant, smooth-scrolling vertical list. Your list can include data from an XML file, a JSON data structure, a SQLite database, or other data sources.
  • Horizontal list - Build a list that scrolls horizontally instead of vertically, giving you more flexibility to display your data.
  • Standard list item - Use this predefined style for normal items in your list, or extend the style to create your own bold list item designs. You can use core UI controls in your design, or create entirely new components to represent your data.
  • Header list item - Take advantage of this predefined style for header items in your list, or use it as a starting point and create a unique header style of your own. Use header items to group list items and make it easy for your users to find the data they need.

Data providing

  • In-memory, or array-based - Use traditional methods of data storage and access, like storing your data in an array in memory.
  • JSON - Store your data in a JSON data structure for a lightweight representation that's easy to use.
  • SQLite - Implement data models that use SQLite to take advantage of relational database capabilities.
A list with different list items.

Animations

  • Implicit animations - Let Cascades do the animating for you! Change property values and watch as UI controls are animated automatically. You can also control whether you want implicit animations to occur or not for controls in your apps.
  • Explicit animations - Control the parameters of your animations precisely by specifying starting and ending positions, duration, easing curve, and more.
  • Fade transition - Change the opacity of controls to emphasize the areas you want in your UI designs.
  • Rotate transition - Rotate controls to add the right spin to your apps.
  • Scale transition - Alter the sizes of your controls dynamically for a perfect fit every time.
  • Translate transition - Move the elements of your app around with responsive and attractive sliding animations.
  • Mutable animations - Make changes to your animations on the fly in response to user input or other factors.
  • Group animations - Use parallel animations to play multiple animations at the same time, or use sequential animations to play them one after another.

Event system

  • You can handle touch events with precision, and keep track of which components in your UI should receive touch events. The Cascades model for touch event propagation gives you the power to control and customize your user interactions.
The built-in animations and easing curves.

Lots of built-in animations and easing curves

Layout system

  • Absolute layout - Determine the layout of your UI down to the pixel, giving you the power to position your controls with precision.
  • Dock layout - Align UI controls in different locations on the screen for lots of flexibility. The controls will stay aligned even if the size or resolution of your UI changes.
  • Stack layout - Place your controls side by side, either horizontally or vertically, and use properties like margins, padding, and space quotas for that perfect arrangement.

Cascades platform APIs

  • Battery - Detect and respond to changes in battery power level.
  • Display - Determine the display size, resolution, ID, name, and aspect ratio of the device.
  • LED - Set the blink color, frequency, and duration of the LED.
  • Network status - Query the status of network connections and receive notification when the status changes.
  • Payment Service - Include the Payment Service library in your app to offer subscriptions, unlock features, or sell any digital good that you've registered on the vendor portal for BlackBerry World.
  • Version API - Determine the version of the BlackBerry OS that's installed on the device.
The powerful layout system.

Known limitations

Cascades UI framework

  • Several limitations and issues exist when entering and displaying text in a TextArea or TextField. Hinting text is not properly displayed and TextArea layouts are not synchronized with content layouts, which can create visual artifacts.
  • Handling of the virtual keyboard is incomplete, and the display of the virtual keyboard is inconsistent and you can't specify the keyboard context.
  • JSON and SQL data access doesn't implement saving, even if the function is available.
  • You may experience some performance issues when creating screens with a large number of controls.

Cascades Builder

  • The UI preview does not support custom controls in QML or custom elements in C++. Using custom controls or elements might result in a limited preview, or no preview, displayed in the UI preview.
  • The QML preview does not work as expected when you open some QML files. You might experience issues with the QML preview, including disabling of the QML preview feature entirely, which could indicate that your hardware configuration is not supported. The QML preview requires a graphics card that supports 3-D acceleration and OpenGL 2.0 support. You might also experience issues if your graphics driver is outdated or obsolete, so it's recommended that you upgrade your graphics driver to try to resolve any issues with the QML preview. You can also disable the QML preview from within the QNX Momentics IDE in the Preferences menu. Also, note that the QML preview is not available if you access the QNX Momentics IDE using Remote Desktop or similar technologies, and you might experience limitations if you're running the IDE in a virtualized environment.

Cascades Exporter

  • The Create and export Button control is incomplete, and may not function when using Windows.
