2020-04-02Strengthen warningsDavid Robillard
2020-04-02Make puglGetVisible() take a const view argumentDavid Robillard
2020-04-02Make puglSetString() safe to call with equal source and destinationDavid Robillard
This is sometimes used by puglSetWindowTitle() using the existing title.
2020-04-02Add missing includeDavid Robillard
2020-04-01Increase space above field documentation slightlyDavid Robillard
2020-04-01Add types and documentation for all event typesDavid Robillard
These are not necessary since they are just aliases for PuglEventAny, but provide a place to put the documentation, and can make code clearer where a specific event type is known.
2020-04-01Consistently use "view" terminology in APIDavid Robillard
The sloppy use of "window" caused quite a bit of confusion, since views only correspond to top-level windows in some cases, and on MacOS, a non-top-level view is not a "window" at all.
2020-04-01Cleanup: Fix mismatched file commentsDavid Robillard
2020-04-01Add PUGL_BAD_PARAMETER statusDavid Robillard
2020-04-01Replace puglShowWindow() with puglRealize()David Robillard
2020-03-31GL3 Demo: Fix conversion warningsDavid Robillard
2020-03-31Mac: Fix various warningsDavid Robillard
2020-03-31Remove unused configuration optionDavid Robillard
2020-03-31Add format attribute to logError()David Robillard
2020-03-31Fix mismatched printf parameter typesDavid Robillard
2020-03-31X11: Don't wait for timeouts less than a millisecondDavid Robillard
2020-03-28Tolerate puglPostRedisplay() in configure handlersDavid Robillard
2020-03-18Reorder event struct definitions to match PuglEventTypeDavid Robillard
2020-03-17Use a more logical order for PuglEventTypeDavid Robillard
2020-03-17Use clearer names for pointer eventsDavid Robillard
These old "notify" names are a smell from X11 which is a bit strange and inconsistent here, since nearly everything is a "notification" of sorts. I think the new names here are much more clear since they are consistent with the keyboard focus events.
2020-03-16Cleanup: Add missing includesDavid Robillard
2020-03-16Italicise the brief description of structs as with functionsDavid Robillard
2020-03-16Embed Demo: Add timer to occasionally reverse spin directionDavid Robillard
2020-03-16Simplify puglRequestAttention()David Robillard
Now that timers are exposed, applications can repeatedly nag for attention themselves if they really want to.
2020-03-16Add timer eventsDavid Robillard
2020-03-16Cleanup: Remove unused includeDavid Robillard
2020-03-16MacOS: Fix semantics of puglUpdate() with negative timeoutDavid Robillard
2020-03-16MacOS: Move initial configure to just before mapDavid Robillard
2020-03-16X11: Dispatch a configure event before the map for child windowsDavid Robillard
It does not seem to be guaranteed that child windows receive a ConfigureNotify at all. Work around this by explicitly dispatching one first, so child views receive events consistently with how top level views do.
2020-03-16Make update test more tolerantDavid Robillard
2020-03-16Separate cached configuration from frameDavid Robillard
This was a bad idea and a never-ending source of problems. The frame represents what the "current" frame is from a Pugl perspective, but with the asynchronicity of X11 and other issues this cant be used to filter configure events. Instead, simply cache the last configure event that was sent and compare with that.
2020-03-16Factor out dispatching configure events in the drawing contextDavid Robillard
The updates here need to happen whenever a configure is dispatched, even outside puglDispatchEvent(). This removes the last remaining direct calls to the event callback so the common implementation can always do the right thing.
2020-03-16Window Demo: Only redisplay on update when running continuouslyDavid Robillard
2020-03-16Only send update events when the view is visibleDavid Robillard
2020-03-15Cleanup: Fix stale commentDavid Robillard
2020-03-15Cleanup: Fix documentation linksDavid Robillard
2020-03-15Update event loop documentationDavid Robillard
2020-03-15Unify event loop functions as puglUpdate()David Robillard
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).
2020-03-15X11: Factor out flushing pending exposuresDavid Robillard
2020-03-15Add type and flags to worldDavid Robillard
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 Robillard
2020-03-15Cleanup: Fix indentationDavid Robillard
2020-03-15Cleanup: Fix misleading variable nameDavid Robillard
2020-03-15Cleanup: Remove redundant PUGL_API declarationsDavid Robillard
2020-03-15X11: Simplify implementation slightlyDavid Robillard
These continue statements are not necessary since the events will not be translated anyway.
2020-03-15X11: Read from server if necessary in puglDispatchEvents()David Robillard
This reduces input lag. The previous approach was an over-optimization: what's important here is to keep the iteration bounded by not continually flushing, but we do want to read everything to be as up to date as possible.
2020-03-15X11: Don't use CAIRO_OPERATOR_SOURCE for blittingDavid Robillard
This causes artifacts in some scenarios. Although CAIRO_OPERATOR_SOURCE should be faster, the default operator works better in the absence of real double buffering.
2020-03-15X11: Only enter drawing context if an expose is pendingDavid Robillard
2020-03-15X11: Update frame immediately on ConfigureNotifyDavid Robillard
This fixes some jittery display issues since the frame can be used before the deferred configure actually gets dispatched.
2020-03-15X11: Factor out selection event handlingDavid Robillard
