2020-03-15Unify event loop functions as puglUpdate()David Robillard1-1/+3
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).
2020-03-09Add PuglEventClient and puglSendEvent()David Robillard1-0/+8
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 Robillard1-0/+8
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

2019-07-24Unify key and character fields and separate text eventsDavid Robillard1-9/+8
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 Robillard1-2/+2
This matches Gtk and is generally less annoying to work with.
