RE: Double Click in an ULCTextField

Hi Paul,

ULC Extension Guide for ULC 6.1 has an example of creating ActionEvent on
the Pie Chart widget.

Nevertheless, I have created a small snippet for you which can be found at
the end of this mail.

Thanks and regards,

Janak

PS: Are you still developing for Ottomobil?
