Configuring User Inputs dl-permalink__symbolPermalink

Introduction

User inputs for a visualization are configured in order to operate the visualization.

For this purpose, you configure input events on visualization elements where follow-up actions are triggered. The combination of user inputs and follow-up actions are defined in the “Input configuration” of an element. For example, you can select a mouse click an element as the input event and opening a dialog as the input action.

Keyboard events can also be configured that trigger actions in a specific visualization view when the events occur. You program this kind of input configuration for a visualization in its “Keyboard Configuration” editor.

In addition, keyboard events can be configured that occur in all visualizations programmed in the application. You configure this kind of input configuration per application below the Visualization Manager in the "Default Hotkeys" tab.

Input is usually performed with the mouse and keyboard as controlling device. You can also configure a user operation by means of gestures.

If a visualization device is not equipped with a mouse, then you can activate standard keyboard handling. Then a user can operate the visualization with the keyboard only by navigating with the arrow keys and triggering events by pressing the [Enter] key.

If a visualization device is not equipped with a keyboard, then you can call a virtual keyboard or a virtual numeric keypad.
