2020-03-15Unify event loop functions as puglUpdate()David Robillard1-7/+32
The previous separation between polling and dispatching was a lie, especially on MacOS where it is impossible to only poll for events without dispatching anything. Providing such an API is misleading, and problematic in various other ways. So, merge them into a single puglUpdate() function which can do the right thing on all platforms. This also adds the behaviour of actually processing all events in the given time interval, which is almost always what clients actually want to do when using a positive timeout (naively doing this before caused terrible input lag).
2020-03-15Add type and flags to worldDavid Robillard1-1/+2
Unfortunately this is an API break, but there's no reasonable way to deprecate the old function and this is required for things to work correctly. The type will be used in following commits to tick the main loop and dispatch events correctly for either case.
2020-03-15Cleanup: Add puglDispatchSimpleEvent() internal utilityDavid Robillard1-2/+1
2020-03-15Cleanup: Remove redundant PUGL_API declarationsDavid Robillard1-1/+1
2020-03-15Remove backend resize methodDavid Robillard1-11/+6
2020-03-14Add logging APIDavid Robillard1-1/+0
2020-03-09Add PuglEventClient and puglSendEvent()David Robillard1-4/+25
This event makes it possible to send an arbitrary event to a view, which is useful for many things. In particular, this method of communication with views will wake up the event loop, unlike hacks in applications that share data in some other way.
2020-03-09Add create, destroy, map, and unmap eventsDavid Robillard1-2/+11
These can be used to do things when a view is created or destroyed, in particular set up the GL context in a more controlled way. Map and unmap events are also added for when views are shown and hidden so application can react to this as well. Towards the deprecation of puglEnterContext() and puglLeaveContext(), which are prone to abuse. squash! Remove client event stuff
2020-03-09Windows: Configure and redraw only when window is shown, not hiddenDavid Robillard1-3/+5
2020-03-09Windows: Remove unused stores of rectDavid Robillard1-2/+2
2020-03-08Windows: Fix initial frame sizeDavid Robillard1-0/+1
2020-03-08Windows: Prevent input in one window from stalling anotherDavid Robillard1-4/+21
This dispatches events on a per-window basic instead of globally, using the same mark trick as before to bound the number of events dispatched. After the events are dispatched, all the windows are updated if they have an invalid region. This ensures that all windows get drawn every iteration if necessary, since Windows itself does not send WM_PAINT messages if there is lots of input activity.
2020-03-08Remove redundant PuglEventCloseDavid Robillard1-1/+1
This is identical to PuglEventAny.
2020-03-02Omit deprecated implementations with PUGL_DISABLE_DEPRECATEDDavid Robillard1-0/+4
2020-03-01Cleanup: Adjust some code to be more clang-format friendlyDavid Robillard1-14/+27
2020-03-01Cleanup: Fix includesDavid Robillard1-1/+2
2020-02-18Pass expose event to backend enter and leave functionsDavid Robillard1-4/+4
This is needed for clipping. Unfortunately, the puglEnterContext() and puglLeaveContext() API was not suitable for this, but this shouldn't matter in user code because it is only used for setup, and is slated for removal anyway. Instead, just call the backend functions directly in the implementation.
2020-02-02Only resize backend when necessaryDavid Robillard1-9/+14
This avoids resizing the backend when the window is only moved, which fixes flicker with Cairo where resizing is expensive.
2019-11-21Rename "backend" headersDavid Robillard1-1/+1
Working on Vulkan clarified what has always been slightly smelly about the design and organization here: not everything that is API specific is really in a "backend" (a PuglBackend). The concrete example is puglGetProcAddress(), which only makes sense for GL and is actually implemented in the "backend" files. Arguably puglGetContext() is also such a thing. So, rename the headers so they can be the place where API-specific things go in general, which happens to include a backend most of the time. The stub is a bit of an exception to this, but whatever. The includes look tidier this way. In place of the old headers are compatibility stubs that just emit a warning and include the new version, which will be maintained for a while.

2019-11-03Windows: Do not require backends to have a surfaceDavid Robillard1-1/+1
This was just leftover cruft from before error handling was cleaned up, any failure to configure must now be reported by the backend.

Prepares the API for proper error handling, even though there isn't any for these functions yet.

2019-09-03Add puglDispatchEvents()David Robillard1-3/+9
2019-09-03Add puglPollEvents()David Robillard1-0/+14
This allows waiting for events for any view in the world. It also improves on puglWaitForEvent() by the addition of a time parameter that allows indefinite blocking, non-blocking polling, and blocking polling with a timeout.
2019-09-03Move puglGetTime() to PuglWorldDavid Robillard1-3/+3
2019-09-03Add PuglWorldDavid Robillard1-8/+22
The old API was broken for programs that manage multiple views, since it was impossible to wait for events on any view. There are also several functions in the API which are not actually associated with views at all, so those can now be moved to the more appropriate PuglWorld to make this more clear. The old puglInit() and puglDestroy() functions are preserved for compatibility, but marked as deprecated.
