This event is fired when Windows messages are to be handled.
Declaration
Description
This event is fired by TElSimpleSFTPClient when the component needs to process Windows messages.
Depending on the architecture of your socket communication (synchronous or asynchronous) you can either process some messages from the message queue or just call Sleep(0) or do nothing.
Return true if SFTP client can continue or false if blocking operation must be stopped.
Use this callback function if you wish to process all incoming messages yourself
while TElSimpleSFTPClient waits for synchronous server response. If this property is
set to nil (null, Nothing), TElSimpleSFTPClient uses its internal message loop to peek and dispatch messages.
