PeepEvents( events, action, mask )
click to toggle source
Behavior varies depending on action.
PEEKEVENT or GETEVENT:
events is the max number of events to retrieve.
Returns an array of Events, or nil if there was an error.
GETEVENT removes them from the queue, PEEKEVENT leaves them.
ADDEVENT:
events is an array of Events (or specific event instances)
to append to the queue.
Returns the number of events added, or -1 if there was an error.

set_app_name( app_name )
click to toggle source
Sets the application name, if the platform supports it. This method is safe
to call even on platforms which do not support it (but does nothing).
Currently this method only has an effect on Mac
OS X.
The effect of this method depends on the platform. On Mac OS X, it sets the text used in the main
application menu.
(Note: this method does not correspond to any part of the SDL API. It communicates with the platform directly.)
Example:
SDL.set_app_name("SpaceQuest 4000")
def self.set_app_name( app_name )
if defined? SDL::Mac
SDL::Mac.set_app_name( app_name )
end
nil
