Mobile devices like smartphones and tablets include web browser applications and therefore are suitable to use a COBOL application via webClient.

When developing applications that could run on mobile devices, developers should keep in mind the restrictions on display size. This means that windows may not fit in the available space, and windows cannot be dragged on mobile browsers.

A suggestion could be do open windows maximized, and eventually using the LM-RESPONSIVE layout manager.

The device's virtual keyboard does not open automatically in most cases, and a "Keyboard" button is provided by webClient in the bottom right corner of the screen. If the user zooms the browser, the Keyboard button will move accordingly and scrolling may be needed to reach the button.

On Android, when the keyboard is shown, the entry field should move into view, while on iOS this does not work, and the user will need to scroll the windows manually to see the entry field.

The virtual keyboard is automatically engaged and enabled by double tapping on the screen, even if no control is focused.

Single tapping on radio buttons or checkboxes should not trigger the virtual keyboard.

When the virtual keyborad appears over a maximized window, the NTF-RESIZED event is fired.
