## Member Function Documentation

## ◆ activate()

virtual int idaapi action_handler_t::activate | ( | action_activation_ctx_t * | ctx | ) |
| pure virtual

Activate an action.

This function implements the core behavior of an action. It is called when the action is triggered, from a menu, from a popup menu, from the toolbar, or programmatically.

Returns
  non-zero: all IDA windows will be refreshed

## ◆ update()

virtual action_state_t idaapi action_handler_t::update | ( | action_update_ctx_t * | ctx | ) |
| pure virtual

Update an action.

This is called when the context of the UI changed, and we need to let the action update some of its properties if needed (label, icon, ...)

In addition, this lets IDA know whether the action is enabled, and when it should be queried for availability again.

Note: This callback is not meant to change anything in the application's state, except by calling one (or many) of the "update_action_*()" functions on this very action.
