OSK(onscreen keyboard) built in LabVIEW base package

[AdarshaPakala]

As touch screens are becoming very popular and limitation of using keyboards in the production sites, the OSK is becoming very popular requirement and in LabVIEW applications.

Add OSK as an in-built property to String and Numeric controller. Based on control type open the numeric only or full keyboard.

The property can be set manually or programmatically.

Access to source code of OSK to customize the keyboard.

Multilingual keyboard option.

Thank you

In the meanwhile this might help: How to load Windows "On-Screen Keyboard" application using LabVIEW

thank you for the information.

I see following limitations with the suggested approach.

1. All the UI control (wich takes user input), we need to write the event handling code to open the keyboard.
2. Code size increases as the number of UI controls increase.
3. We can’t customize the keyboard - example I need to have numeric keyboard for numeric controllers and string + numeric for string controller. This is not possible.

1. All the UI control (wich takes user input), we need to write the event handling code to open the keyboard.

It would be convenient if LabVIEW handled this.

2. Code size increases as the number of UI controls increase.

You can and make 1 VI that handles it all controls, by dynamically registering for all controls on a VI.

3. We can’t customize the keyboard - example I need to have numeric keyboard for numeric controllers and string + numeric for string controller. This is not possible.

I'm not sure if that's the norm.

I don't think LabVIEW should create an OSK. The OS seems to do that, and the OS's OSK is what users expect.

Maybe LabVIEW can set a regional or something to have some control, but the OSK feels more like a OS thing to me.

Something to consider for someone implementing this...

I don’t think you are looking at the bigger picture😉  There is not much option to customize the OS OSKs. For example, I had so many Kiosks kind of application where customer wants to remove the ‘Windows’, ‘Alt’, ‘Ctrl’ etc. buttons to avoid user accessing the OS features(Like Task manager, Device Manager etc) using the OSKs. As off now we can’t customize the OS OSKs much and we don’t know when OS providers will come up with features do that.

As touch screen applications are increasing having an integrated OSK with LabVIEW gives more flexibility and time saving in development.

Thank you
