pre_filter_message()

virtual bool xtd::forms::imessage_filter::pre_filter_message ( const message &  m )

pure virtual

Filters out a message before it is dispatched.

Parameters

m	The message to be dispatched. You cannot modify this message.

Returns

true to filter the message and stop it from being dispatched; false to allow the message to continue to the next filter or control.

Remarks

Use pre_filter_message to filter out a message before it is dispatched to a control or form. For example, to stop the click event of a button control from being dispatched to the control, you implement the pre_filter_message method and return a true value when the click message occurs. You can also use this method to perform code work that you might need to do before the message is dispatched.
