Nowadays, devices are more and more capable of displaying pixels in higher densities than ever. The new ClientUI features an upgraded rendering feature that allows controls to be displayed in high densities without losing their fidelity. The controls are now able to display sharply rendered pixels across all devices, supporting either low or high density displays.
ClientUI is a pioneering solution, introducing an engaging way to input time value. Simulating an analog clock input, ClientUI’s UXClock allows user to visually interact with the hour and minute hands. Conforming to ISO 9241 standards, you can use TAB key to navigate between both hands, and use Up or Down arrow key to increase or decrease the value of the focused hand. Additionally, use CTRL + Click to move the hour and minute hands exactly. Slide the AM/PM to change the value as desired.
The input and button controls in ClientUI feature visual keyboard focus, similar to Windows OS and WPF standards. This is one of the most fundamental usability features that help users easily spot the focus of primary input device during data entry process. Users can use TAB and SHIFT+TAB key to move between input elements, buttons, and more.
Visual hint is an important feature to notify user on the current system or application state. For example, using a progress bar in a form-filling scenario enables user to be aware of the saving. Without proper indication, user can be easily misled with the current state of a command. ClientUI includes a thoughtfully engineered visual hint for disabled and busy state feature.
Access key is an all-time favorite feature. It lets users to quickly accessing a specific command with combination of keystrokes, for instance, pressing CTRL+S to execute the save command. Thanks to the solid focus scope implementation, the access key in menu bar is consistently processed when the current focus is within the same focus scope as the menu bar.
ClientUI simplifies the tedious layouting tasks with its Layout Adorner feature. It is a sophisticated designer feature in Visual Studio and Expression Blend that displays a visual cue to allow you easily interact and layout the user interface elements. When you select a DockPanel instance, you will notice the helpful cue indicating the dock position of the currently selected element. Click on the cue to move it around.
Although Silverlight has provided basic keyboard navigation functionality, ClientUI improves it further by adding a more advanced keyboard navigation support to its essential UI controls. A sophisticated focus and input management feature is also implemented in certain advanced controls such as dropdown button, split button, toolbar button, and more.
Users can use the TAB key to focus on a dropdown element and arrow key to expand the dropdown and move between selections. When interacting with the toolbar, you can use the arrow key to move between menu items and sub menus, press the ESC key to hide the menu and press ESC key again to return the focus to the previously selected element.
Input modality is one of the most fundamental UI architecture that has been long adopted by popular platforms such as Windows and Mac. The most common implementation of input modality can be often found in dialog boxes, menu, and popup. When the UI requires a sole user focus, the UI routes all input events to that particular UI elements allowing users to easily focus on a specific single task, for example, when selecting a command from a menu, the user input is modal to the menu element.
Things become more complicated when there are multiple UIs that require user focus. In this case, the precedence of modality should be applied to determine which input should be first processed. This scenario can often be found in multiple window interface applications where a window should be less modal than the task bar UI, and the task bar UI should be less modal than menu or popup.
