Touchscreens

On a Windows 10 or 11 machine with a touchscreen that presents itself to Windows as a touchscreen input device (as opposed to using mouse emulation), then clicking on an edit field will cause the Windows Touch Keyboard to appear automatically.

If the machine also has a keyboard plugged-in and you still want the touch keyboard to appear when you touch an edit field on the touchscreen, you may need to enable a Windows setting as described here: https://www.windowscentral.com/auto-display-touch-keyboard-windows-10-desktop-mode.

For some devices, "tablet mode" must be enabled.

 

New to VTScada 12.1 is that a Momentary Button (that is configured to show a non-legacy button) will react to touch input. (The Momentary Button does not react to a touchscreen if Show Button is off or if it is configured with an opacity of zero.)

Many touchscreens only support mouse emulation. Those do not have support for the standard Windows Touch Keyboard, in VTScada or any other application. To test, open Notepad and tap its text editing area. If the touch keyboard appears, then you can expect it also to work in VTScada. If not, then it won't work in VTScada either.
