The problem I'm having is the following: is there an elegant way to prevent the user from clicking the 'Test' button in the Screen Savers panel in System Preferences?
The reason why I'm asking: when the user changes the configuration in my screen saver, I start a Spotlight query that could take up to 30 seconds (about 10 seconds for the initial phase of the search itself, plus 20 seconds for retrieveing the results from the query).
The results of that query then change what the screensaver renders.Therefore, I would like to give the user some feedback that the query is still in progress *AND* I would like to prevent the user from clicking that 'Test' button in System Preferences' Screensaver pane.
Right now I'm using an asynchronous NSMetadataQuery, which seems to work, except that the only way to prevent the user from clicking that 'Test' button I found was to keep the configuration sheet up until the search has completely finished.
IMHO, this doesn't look very elegant ;-/ Any ideas will be highly appreciated. Best regards, Gabriel.
