Hello everyone,

I have a question regarding the custom region. I want to perform some changes when the custom region lost the focus from the user (like when the user click on the main canvas instead of the custom region). But so far that I understand from the SMath core documentation, there is no method that can deal with this event that I can override (like OnMouseDown or OnMouseMove). Is there any alternative to achieve this?

Best Regards,

Faiz

Hi Faiz,

You can add an event handler to FocusChanged, also you can check the Focused property within the OnPaint method. F.E. both are used here, hope it helps.
