External keyboards
JMobile HMI Runtime has been designed to work with external keyboards connected via USB.
USB Barcode readers that support keyboard emulation mode can be used.
Keyboards can be used for:
- data entry (default)
- execute actions mapped on specific keys
For example, the right arrow key OnClick event can be mapped to the LoadPage action.
Keyboard can be programmed at project level so that settings will be inherited by all the pages. In each page you can then choose which key setting will be inherited from the project and which one you will customize for the specific page.
Opening external keyboards
- In the Page Editor, click on the icon on the right of Keyboard/Script at the bottom of the workspace: the Keyboard/Script Editor is displayed.
- Select the Keyboard tab.
Each row in the Keyboard Editor corresponds to a key.
For each key, the following information is displayed:
