* partial implementation for emscripten
this pull request contain a partial but working implementation of emscripten backend
some implementations may be controversial.
here some implementation detail:
* cursor state:
* on grab: emscripten request pointer lock deferred and also set a callback when pointer lock change
the callback request pointer lock deferred.
* on hide: `emscripten_hide_mouse` exist but not `emscripten_show_mouse`
a pull request has been open on october 2016 but never been merged
so I copied the javascript function and put it in emscripten_asm_const function
* fullscreen: if fullscreen is requested then it request fullscreen deferred and set a callback on fullscreen change
the callback request fullscreen deferred
* run forever: this method use emscripten main loop to run an infinite loop
* keyboard callback doesn't consume the event. I think it is more apopriate as in desktop environment it is the same, is it ?
* emscripten dir is added in example and contains html pages
Some things that are not implemented:
* lots of events
* min and max dimension can be implemented with a callback that listen to size change and resize if dimension out of bound
* title may be implemented using javascript to change document.title
* Use std::os::raw in the emscripten bindings
* Fix emscripten code
* Update code
* Add CI
* Remove the emscripten-specific examples
* Add some information to the README
* Fix X11 screen resolution change using XrandR
The previous XF86 resolution switching was broken and everything
seems to have moved on to xrandr. Use that instead while cleaning
up the code a bit as well.
* Use XRandR for actual multiscreen support in X11
* Use actual monitor names in X11
* Get rid of ptr::read usage in X11
* Use a bog standard Vec instead of VecDeque
* Get rid of the XRandR mode switching stuff
Wayland has made the decision that apps shouldn't change screen
resolutions and just take the screens as they've been setup. In the
modern world where GPU scaling is cheap and LCD panels are scaling
anyway it makes no sense to make "physical" resolution changes when
software should be taking care of it. This massively simplifies the
code and makes it easier to extend to more niche setups like MST and
videowalls.
* Rename fullscreen options to match new semantics
* Implement XRandR 1.5 support
* Get rid of the FullScreen enum
Moving to just having two states None and Some(MonitorId) and then
being able to set full screen in the current monitor with something
like:
window.set_fullscreen(Some(window.current_monitor()));
* Implement Window::get_current_monitor()
Do it by iterating over the available monitors and finding which
has the biggest overlap with the window. For this MonitorId needs
a new get_position() that needs to be implemented for all platforms.
* Add unimplemented get_position() to all MonitorId
* Make get_current_monitor() platform specific
* Add unimplemented get_current_monitor() to all
* Implement proper primary monitor selection in X11
* Shut up some warnings
* Remove libxxf86vm package from travis
Since we're no longer using XF86 there's no need to keep the package
around for CI.
* Don't use new struct syntax
* Fix indentation
* Adjust Android/iOS fullscreen/maximized
On Android and iOS we can assume single screen apps that are already
fullscreen and maximized so there are a few methods that are implemented
by just returning a fixed value or not doing anything.
* Mark OSX/Win fullscreen/maximized unimplemented()!
These would be safe as no-ops but we should make it explicit so
there is more of an incentive to actually implement them.
* Don't use UNIX_BACKEND in Window2::new
* Move get_available_monitors and get_primary_monitor to EventsLoop
* Remove UNIX_BACKEND
* Restore choosing the Linux backend
* Return a XNotSupported for new_x11()
* Fix fullscreen example
* Rework MonitorId::get_native_identifier
* Try fix compilation
* Returns the monitor ID on wayland as well
* Try fix compilation
* Fix iOS compilation
Use the enum to make a single fullscreen API that's much more
consistent. Both set_fullscreen() and with_fullscreen() take the
same enum and support all the variations so you can build the window
however you want and switch between the modes at runtime.
There are two kinds of fullscreen. One where you take over the whole
output the other where you just set the window size to the screen
size and get rid of decorations. The first one already existed,
implement the second which is more common for normal desktop apps.
Use an enum to consolidate all the fullscreen states.
When X's evdev input module is configured to emulate scroll events (as
used with e.g. trackpoints), it generates non-emulated scroll button
presses and does not generate motion events. This is contrary to the
behavior of all other hardware I've tested, and contrary to the
behavior of libinput, but nonetheless should be supported.
X11 always return the geometry in pixel units. Since
window.get_inner_size returns the size in points in other window manager
implementations X11 should also return in points instead of pixels.
This removes the need for the EventsLoop::interrupt method by inroducing
a ControlFlow type. This new type is to be returned by the user's
callback and indicates whether the `EventsLoop` should continue waiting
for events or break from the loop.
Only the wayland, x11 and api_transition backends have been updated so
far, and only the wayland backend has actually been tested.
X11 and Wayland implementations are now half implemented, however both
still do not correctly break from the inner blocking event dispatch
functions when `wakeup` is called, which they should do.
This commit only updates the top-level API to get some early feedback.
None of the platform-specific code has been updated yet. I'm hoping to
get around to this over the next couple days however if someone more
familiar with the windows backend would like to do a PR against this
fork that would be a great help.
Closes#187.
