open the Windows virtual keyboard in a Java program

Question

I would like to create an event in a button.

When I click in the button, I would like to open the Windows virtual keyboard.

Can you help me with the code?

Thank you for your collaboration.

Best regards.

Answer 1

You can use getRuntime to execute it:

import java.io.IOException;

public class ShowVirtualKeyboard{

    public static void main(String argv[]) throws IOException {
    String sysroot = System.getenv("SystemRoot");
    Process proc = Runtime.getRuntime().exec(sysroot + "/system32/osk.exe");
}
}

and you can call proc.destroy() to get rid of it.

Regards.

Answer 2

I think it would be as simple as this: Runtime.getRuntime().exec("osk");

Answer 3

This will work: Runtime.getRuntime().exec("cmd /c osk");

cmd /c will launch the process and invoke the UAC if needed.

Advantage:

• And it would avoid privileges issue.

Disadvantage:

• Would not be able to turn off by Process instance on java.
