2019-07-29X11: Implement double buffering for CairoDavid Robillard1-31/+66
Also save and restore cairo context state around callbacks, so applications don't need to worry about smashing cairo state across exposures.
2019-07-29Mac: Separate backends from platform implementationDavid Robillard4-390/+445
2019-07-29Mac: Add Cairo on Quartz supportDavid Robillard2-132/+113
This avoids the general hassles of OpenGL, which is deprecated on MacOS, and Cairo apps look much nicer and more integrated this way. As far as I can tell, Cairo actually works best here out of all the platforms, the Windows and X11 backends aren't quite as smooth.
2019-07-29Mac: Make drawView a generic NSViewDavid Robillard1-20/+46
2019-07-29Mac: Separate NSOpenGLView from input handling viewDavid Robillard1-113/+142
2019-07-29Mac: Use scrolling delta for scroll eventsDavid Robillard1-2/+2
I am not sure exactly what the difference is between these, but the documentation says to use these for scroll events. They do have different values for touchpads and the scrolling one feels a bit nicer.
2019-07-29Cleanup: Clean up includes and call IWYU in lint targetDavid Robillard6-1/+17
2019-07-29Fix various clang-tidy warningsDavid Robillard3-15/+15
2019-07-29Fix potential memory leak on errorDavid Robillard1-0/+1
2019-07-29Reorganize source to separate private implementation detailsDavid Robillard15-43/+83
Taking a page from C++ convention, where "detail" is for things that should not be included in user code.
2019-07-29Clean up file documentationDavid Robillard15-9/+33
2019-07-29Completely separate backends from platform implementationDavid Robillard10-75/+43
This removes PuglContextType and allows the user to pass a backend directly. Normally this would come from one of the two accessors declared in the headers, but it would be possible to add backends without changing any of the existing code at all. Unfortunately, it is not possible to preserve backwards compatibility and achieve the ultimate goal of linking only to the required dependencies, so puglInitContextType() has just been removed.
2019-07-29Expose PuglBackend typeDavid Robillard2-3/+5
2019-07-29Add deprecation macro and deprecate puglInitResizable()David Robillard1-1/+11
2019-07-29Move trivial backend dispatch functions to common codeDavid Robillard4-54/+18
2019-07-29Move backend to PuglViewDavid Robillard6-53/+53
2019-07-29Mac: Factor some functionality out into a backendDavid Robillard1-38/+151
Not quite as isolated as the other platforms at this point (Objective C makes this tricky), but a step towards that and being able to simplify things in the common code by assuming that all platforms have a backend.
2019-07-29Windows: Disable DPI scalingDavid Robillard1-0/+12
This is probably not ultimately the right thing, especially without a DPI/scaling access API, but it makes the horrible default fuzziness go away.
2019-07-29Windows: Add Cairo supportDavid Robillard2-0/+215
2019-07-28Windows: Factor out GL backendDavid Robillard4-270/+427
2019-07-28Make enterContext take a drawing parameter like leaveContextDavid Robillard8-41/+53
These need to be symmetric because sometimes different things need to happen in either situation when entering the context as well.
2019-07-28Give backends general namesDavid Robillard6-30/+52
Towards making them opaque and exposing them to the user to decouple the core library from backends. The general names mean that it won't be possible to build multiple backends for one platform into the same binary, but that seems reasonable for now, and it will make things simpler without needing to add a bunch of dispatch code. That will still be possible if it's ever needed, though.
2019-07-28Rename getHandle to getContext for consistent terminologyDavid Robillard4-6/+6
2019-07-28Rename PuglDrawContext to PuglBackendDavid Robillard7-29/+29
This name was pretty confusing since there is already the concept of a "context".
2019-07-28Cleanup: Remove redundant preprocessor checksDavid Robillard1-4/+0
2019-07-28Cleanup: Remove redundant context type checksDavid Robillard1-7/+3
2019-07-28Cleanup: Add some constnessDavid Robillard1-2/+2
2019-07-28Mac: Fix warningDavid Robillard1-1/+2
2019-07-28Fix unused parameter warnings and prevent rotDavid Robillard7-28/+52
2019-07-26Windows: Implement size constraintsDavid Robillard2-0/+49
There are two possible approaches to take here: try to expand dimensions that are not being explicitly resized (for example expand the bottom when dragging right), or just stop single-dimension resizes if they would go out of range. I chose the latter here for two reasons: it's hard to always do something smooth and unsurprising with the first approach (and it would require more code), and it can be nice from the user's perspective to easily be able to resize the window to exactly one of its aspect ratio limits. For example, it is very easy to drag pugl_test to 1:1 or 16:9. In other words, simplicity and user power wins.
2019-07-25Clear GL context in puglLeaveContext() on all platformsDavid Robillard2-0/+3

2019-07-25Add missing includeDavid Robillard1-0/+1
2019-07-25Mac: Fix build on MacOS older than 10.10David Robillard1-0/+6
2019-07-25Mac: Use mach_absolute_time()David Robillard1-4/+3
This fixes the build for older versions of MacOS, since clock_gettime() was only added in 10.12.
2019-07-25Use standard Cairo include paths everywhereDavid Robillard1-2/+2
Weird convention, that.
2019-07-25Windows: Fix initial display once againDavid Robillard1-5/+6
I have no idea why this affects anything, but it seems to fix this, this time, again. One of these days I'll get it right.

2019-07-25Handle backspace and delete consistently across platformsStefan Westerfeld2-0/+4
2019-07-24Support additional special keysDavid Robillard4-79/+133
2019-07-24Unify key and character fields and separate text eventsDavid Robillard4-205/+278
Only one field is necessary to store any kind of key, including special keys, since PuglKey occupies a reserved Unicode region. This is generally much simpler to deal with since there is only one value to dispatch on. Text events are separated from key events (like Windows but unlike MacOS or X11) because it is not possible to derive text events from key press events when they occur on Windows. Since merging the two has been the source of some confusion, this approach has some advantages anyway, even though it introduces the need to handle another event type. In the process, text input has been almost completely rewritten. I have tested this with a compose key on X11 and dead keys on Windows and MacOS and everything seems to work correctly, though there may (as always) still be issues with more exotic input methods.
2019-07-24Rename PuglEventKey::utf8 to "string" with char typeDavid Robillard4-28/+27
This matches Gtk and is generally less annoying to work with.
2019-07-24Remove view pointer from eventsDavid Robillard4-31/+13
This makes events POD, which is generally nice. The view was originally added to reflect the display and window references in XEvent, but doesn't seem very useful in Pugl applications.
