IDCMP class: User pressed close button of window
Source position: intuition.pas line 860
const IDCMP_CLOSEWINDOW = $00000200; |
IDCMP_CLOSEWINDOW messages are sent when the user selects the window's close gadget. Intuition does not close the window when the close gadget is selected. Rather, an IDCMP_CLOSEWINDOW message is sent to the window's IDCMP. It is up to the application to clean up and close the window itself. If closing a window means losing some data (perhaps the spreadsheet the user was working on), it would be appropriate for the application to first confirm that the user really meant to close the window.
