Connect Cairo and UI

Suppose, I want to show some figure, that'll be drawing by Cairo after button clicking. So, when I start my app I need to create UI with button and add clicked event handler, that'll start drawing. What is the right way to destroy UI and start drawing?

Please, help :)

Hello,

You can add button and callback using following example:

After clicking you can hide this button using evas_object_hide (Evas_Object *obj) method and start drawing:

Hi,
If you plan to use this button after: you could hide button (as proposed above) with evas_object_hide and show it again with evas_object_show. Registered "clicked" smart callback will be stored in this case.
Also you could delete button with evas_object_del at all.
Alexey.
