TypeScript Syntax

class lt.Controls.ImageViewerInteractiveModes()

Remarks

ImageViewerInteractiveModes holds the collection of ImageViewerInteractiveMode instances used by an ImageViewer.

Use the various LeadCollection properties and methods to add, insert, remove, get/set and enumerate the items of this class.

ImageViewerInteractiveModes also supports the following:

BeginUpdate and EndUpdate to optimize performance when adding or removing multiple items at once.
Enable, EnableByIndex and EnableById to quickly enable or disable an interactive mode.
FindById to quickly find a more by its ID.

In applications where only one interactive mode is enabled at a time, the modes are added all at once when the application starts and then the user can select which to enable using a user interface element such as a menu item or a combo box. In these types of application, the user can enable the desired mode quickly using Enable, EnableByIndex or EnableById instead of looping through all the items in the collection as shown in the example below.

For more information, refer to Image Viewer Interactive Modes.
