Is there a way to change the sign of a numeric number by sending a specific keyboard code (like in Windows Calculator)

[jnpomies]

Hi everyone,

I actually developp a numeric keyboard emulation and I would like to emulate the behavior of the Windows calculator for the sign changed. I explain the purpose : I would like to change the sign of the numeric input when I stroke a own defined image button (+/-). Is there a another solution that to allocate dynamically a variable with the same type as the UIR numeric input and use the minus operator to change the sign...

Thank you for your answer,

Regards,

Within the callback for the numeric control, you could trap the EVENT_KEYPRESS event and check that the key pressed was the one you have assigned the +/- operation to. It is then a simple matter to negate the value held in the control.
