SlidingContainer Widget Basics
Note: The SlidingContainer Widget is supported in Windows 10 only.
The widget is a container with two views. One view is for the main content, and the second view is used for navigation commands. The following image shows the main content view of the widget.
The following image of the open widget shows the navigation commands.
The SlidingContainer has two areas of content: a commandPanel and a contentPanel.
The contentPanel area is always present and can contain a single child element, typically a Box- or Flex-derived container that contains additional child elements.
Although the contentPanel is always present, it can be completely covered by the commandPanel. You use the properties of the SlidingContainer Widget to change the appearance and behavior of the commandPanel. For example, you can:
- Use the openCommandPanel property to open or close the commandPanel pane. The SlidingContainer widget allows users to toggle the state of the pane, like a menu (or “hamburger”) button.
- Use the commandPanelExpandedWidth property to specify the width of the open commandPanel.
- Use the commandPanelPosition property to show the commandPanel on either the left or right side of the contentPanel.
- Use the menuDisplayMode property to configure the interaction of the commandPanel with the contentPanel. By default, the commandPanel overlays the contentPanel and has a compact size when closed. Using the property you can show the commandPanel side-by-side with the contentPanel, or have a narrow section of the commandPanel remain visible even when it is closed.
Creating a SlidingContainer Widget Using a Constructor:kony.ui.SlidingContainer
You can create a SlidingContainer Widget dynamically using JavaScript code.
var container = new kony.ui.SlidingContainer(allConf);
or
var container = new kony.ui.SlidingContainer(basicConf, layoutConf, pspConf);
- basicConf is an object with basic properties.
- layoutConf is an object with layout properties.
- pspConf is an object with platform specific properties.
Important Considerations
- Use the SlidingContainer Widget only as a screen-level widget as suggested by Microsoft UI guidelines.
- Use only container widgets for the commandPanel and contentPanel.
- A better practice is to create a global content object and change the contentPanel by assigning global objects to it. It will switch smoothly between the two content items.
