Functions
Add a function which is called when an event is added to the queue.
Remove an event watch function added with SDL_AddEventWatch
This function allows you to set the state of processing certain events.
Run the filter function on the current event queue, removing any events for which the filter returns 0.
This function clears events of a particular type from the event queue.
This function clears a range of event types from the event queue.
Return the current event filter - can be used to “chain” filters.
As SDL_EventState, but provides the “query” part for you.
Checks to see if certain event types are in the event queue.
Checks to see if a range of event types are in the event queue.
Checks the event queue for messages and optionally returns them.
Polls for currently pending events.
Pumps the event loop, gathering events from the input devices.
Add an event to the event queue.
This function allocates a set of user-defined events, and returns the beginning event number for that set of events.
Sets up a filter to process all events before they change internal state and are posted to the internal event queue.
Waits indefinitely for the next available event.
Waits until the specified timeout (in milliseconds) for the next available event.
Type Definitions
