2023-01-11Remove cached frame from viewDavid Robillard1-41/+89
This was just a source of ambiguity and bugs, since it represented different things at different times and could become stale. Redundant data is always trouble, so eliminate it, leaving just two positions/sizes: the defaults (used when the view is not yet realized), and the last configuration.
2023-01-11Fix checks for invalid view positionsDavid Robillard1-1/+1
2023-01-10Add PUGL_CURSOR_ALL_SCROLLDavid Robillard1-0/+1
2023-01-10Fix inconsistent naming conventionDavid Robillard1-5/+5
2023-01-08Remove branch cloneDavid Robillard1-2/+0
2023-01-08X11: Add support for _NET_WM_PING protocolDavid Robillard1-14/+53
This is mainly used to allow the window manager to close locked or otherwise misbehaving windows. The PID and hostname properties are both required to properly support this, but may also be used for other things.
2023-01-08Add support for raising windowsDavid Robillard1-2/+13
2023-01-07Replace map/unmap events with more expressive configure eventsDavid Robillard1-17/+21
2023-01-07Add support for special view types and stylesDavid Robillard1-51/+185
2023-01-07Support closing views by sending a close eventDavid Robillard1-4/+26
2023-01-07Rename create/destroy events to realize/unrealizeDavid Robillard1-4/+3
As evidence that this was confusing, the documentation for these was an outright lie, and I've burned quite a bit of time in the past few days trying to rework things based around that flawed understanding. These names make it clear what these events actually are. If we need actual create/destroy events with a broader scope, they'll have to be added, but I suspect those aren't actually useful anyway.
2023-01-07Replace visible flag with a more descriptive view "stage"David Robillard1-4/+4
2023-01-04Add puglUnrealize()David Robillard1-16/+50
2023-01-02X11: Factor out getCurrentConfigurationDavid Robillard1-11/+18
2023-01-02Factor out common realize checks and initializationDavid Robillard1-14/+4
2023-01-02Fix PUGL_NUM_CURSORSDavid Robillard1-3/+1
2022-12-27Fix inconsistent initial window positioning across platformsDavid Robillard1-1/+1
2022-12-27Set transient parent when views are realized if necessaryDavid Robillard1-1/+1
2022-12-27Fail to set transient parent of views with a parent windowDavid Robillard1-0/+4
2022-12-24Fix weird/inconsistent control flow in puglSetSize()David Robillard1-3/+2
I'm not really sure about directly updating the frame like this - or whether these fields should even exist in the first place (it's questionable whether the view is "really" the new size until the configure process is complete) - but regardless, the same pattern should probably be used for both size and position. "Probably", because touching anything like this tends to break some situation or another somewhere, but such is life.
2022-12-24Add diagonal cursorsfalkTX1-2/+4
2022-10-07Use uppercase integer literal suffixesDavid Robillard1-10/+10
2022-07-16Fix missing field initializers when building as C++falkTX1-3/+3
2022-06-17Call XrmInitialize()David Robillard1-0/+1
This must be called before any other Xrm functions are used.
2022-06-08Use consistent terminology for native viewsDavid Robillard1-1/+1
On MacOS in particular, views and windows are entirely different concepts, so confusing them... confuses things. This was the last holdover in the API that used the old "native window".
2022-06-08Separate platform.h from internal.hDavid Robillard1-0/+1
This makes the internal header structure match the "kinds" of definition inside Pugl: common implementations of public API, things available internally to platform implementations, and things the platform must define.
2022-06-08Separate private and public function implementationsDavid Robillard1-1/+1
2022-06-08Fix potential null pointer dereferenceDavid Robillard1-5/+5
According to clang-tidy anyway, I'm not seeing it.
2022-06-07Remove unnecessary forward-compatibility codeDavid Robillard1-4/+0
2022-06-07X11: Simplify dispatchX11Events()David Robillard1-31/+44
2022-06-07X11: Flush before returning from puglRealize()David Robillard1-0/+8
This avoids bugs in plugins, because otherwise it's possible that size hints are not available when the host embeds the UI.
2022-06-03X11: Fix crash when input context is unavailable due to localesPace Willisson1-11/+17
Calling X*ICFocus on NULL segfaults. This can happen if XCreateIC failed, for example due to missing locales on minimal Docker images.
2022-05-28Omit cursor_names if XCursor is not availableDavid Robillard1-0/+2
This avoids a Wunused-const-variable warning with GCC.
2022-05-23Add rich clipboard supportDavid Robillard1-84/+286
This implements a more powerful protocol for working with clipboards, which supports datatype negotiation, and fixes various issues by mapping more directly to how things work on X11.
2022-05-21Add puglGetScaleFactor()David Robillard1-1/+36
2022-05-21Add puglSetPosition() and puglSetSize()David Robillard1-5/+48
These are redundant with puglSetFrame in a sense, but allow setting the size of a view without the position, or vice-versa. This API also maps more nicely to Wayland, where applications can not position themselves (but can resize).
2022-05-21Use consistent integer types for view positions and sizesDavid Robillard1-25/+25
Actual window sizes and positions fit easily in a 16-bit integer. So, we use that in "representation contexts" like events. This makes structures smaller, and allows the values to be converted to float, double, or integer without casting (since any int16_t or uint16_t value can fit in them without loss). Setter APIs use native integers for convenience, to avoid casting hassles when doing arithmetic. Ranges are checked at runtime.
2022-05-21Add a uniform API for setting size hintsDavid Robillard1-49/+42
This collapses many functions into one, which makes the API more easily extensible and reduces code size.
2022-05-21X11: Remove redundant display memberDavid Robillard1-33/+38
2022-05-21Rename PUGL_UNSUPPORTED_TYPE to be more genericDavid Robillard1-1/+1
2022-05-21X11: Use cursor themesDavid Robillard1-26/+41
This changes to getting cursors by name from the cursor theme, which makes the cursor match the ones used in modern desktop environments. As far as I can tell, there is no real standard for names, these ones seem to work for me in GNOME, KDE, and Xfce. I am not sure about the compatibility concerns here, but X11 without Xcursor themes strikes me as either too esoteric or too ancient to worry about, especially since cursor switching isn't critical functionality anyway.
2022-05-21Avoid setting cursor on realizationDavid Robillard1-4/+0
This avoids issues when the default X11 cursor isn't the expected "default" of the environment, for example with Plasma. A real application that changes the cursor needs to do so consistently on mouse enter and leave events anyway.
2022-04-23Fix IWYU warningsDavid Robillard1-1/+0
I suspect that using the same configuration across both C and C++ is starting to wear a bit thin, but this will do for now.
2022-04-23Move reserved platform defines from code to build systemDavid Robillard1-4/+0
Numerous things warn about this, and it's generally a bad idea to put these in the code since it can result in incompatibly compiled code being linked together. Unfortunately this makes building manually (without the build system) more fiddly, but such is life.
2022-04-21Improve error handlingDavid Robillard1-38/+55
2021-12-17Reduce variable scopeDavid Robillard1-2/+2
2021-12-17Adopt REUSE machine-readable licensing standardDavid Robillard1-17/+4
See https://reuse.software/ for details.
2021-12-17Make button numbers consistent across platformsDavid Robillard1-1/+8
There's no universal consensus on how buttons are numbered. Left, right, middle as 0, 1, 2 seems to be the most common convention on modern vaguely similar libraries, so I've gone with that. The switch to zero-based indices will obviously break all current client code. Particularly since now is the time to finish any breaking changes before a stable release, I think that is better than only changing the middle and right numbers, which would likely go unnoticed.
2021-12-16Rename puglSetTransientFor to puglSetTransientParentDavid Robillard1-1/+1
2021-12-16X11: Fix potential crash in puglGrabFocus()David Robillard1-1/+10
This is really a mistake in user code, but things shouldn't crash in general. So, this commit fixes the crash and adds some documentation so that developers hopefully don't try to grab focus before it makes sense. The case that was previously a crash will now gracefully fail, that is, the focus will not be (and can not be) grabbed.
