Title: How to programmatically close windows created by calling capi:display
ID: 10015
| Product: LispWorks for Windows Version: All OS: All Windows platforms | |
| Description: This is a multithreading problem. By default, capi:display creates a new light-weight process for the interface using mp:process-run-function and, in MS Windows, calls to capi:destroy or capi:quit-interface must be in the same process as the window itself. You need to execute the capi:destroy in the interface's process. Usually this happens automatically, for example via a callback from the interface itself. In cases where you want to destroy an interface from another window, use capi:execute-with-interface to call the function in the process associated with the interface. eg (setq interface (capi:display (make-instance 'capi:interface))) (capi:execute-with-interface interface 'capi:destroy interface) or (capi:execute-with-interface interface #'(lambda () (capi:destroy interface))) | |
