How to hide virtual keyboard in Qt?

[zed220]

Hi all,

I have a very simple code to start/show the virtual keyboard which works fine

keyboard = new Keyboard(this);

keyboard = new Keyboard(this);

To copy to clipboard, switch view to plain text mode 

but I can not hide it dynamically I have tried

keyboard->disconnect();

keyboard->disconnect();

To copy to clipboard, switch view to plain text mode 

also this

keyboard->deleteLater();

keyboard->deleteLater();

To copy to clipboard, switch view to plain text mode 

Has anyone got any suggestions please.
