2020-05-19ui/sdl2: start in full screen with grab enabledVolker Rümelin1-5/+4
QEMU with SDL 1.2 display used to enable keyboard and mouse grab- bing when started in full screen. The SDL 2.0 code tries to do the same but fails to enable grabbing because sdl_grab_start(0) returns early. To do it's work the sdl_grab_start() function needs a pointer to a sdl2_console structure.

2019-08-16sysemu: Split sysemu/runstate.h off sysemu/sysemu.hMarkus Armbruster1-0/+1
sysemu/sysemu.h is a rather unfocused dumping ground for stuff related to the system-emulator. Evidence: * It's included widely: in my "build everything" tree, changing sysemu/sysemu.h still triggers a recompile of some 1100 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h, down from 5400 due to the previous two commits). * It pulls in more than a dozen additional headers. Split stuff related to run state management into its own header sysemu/runstate.h. Touching sysemu/sysemu.h now recompiles some 850 objects. qemu/uuid.h also drops from 1100 to 850, and qapi/qapi-types-run-state.h from 4400 to 4200. Touching new sysemu/runstate.h recompiles some 500 objects. Since I'm touching MAINTAINERS to add sysemu/runstate.h anyway, also add qemu/main-loop.h.

2019-01-21sdl: add support for high resolution window iconDaniel P. Berrangé1-6/+12
Modern desktop environments can render icons at very large sizes, especially with high DPI screens. Providing a 32x32 pixel bitmap is nowhere near sufficient anymore. When displayed in GNOME shell the QEMU icon looks awful, having been scaled up to at least x4 its base size. This is compounded by the fact that the BMP file doesn't do transparency, so while we've removed white pixels, we still have anti-aliased nearly-white pixels which make the logo look appalling on black backgrounds. Loading a high resolution PNG icon addresses both problems, but requires use of the extra SDL2_image library. Signed-off-by: Daniel P.

2019-01-21ui: install logo icons to $prefix/share/iconsDaniel P. Berrangé1-10/+6
QEMU currently installs logos to $prefix/share/qemu/ which means no GUI toolkit or applications can find them by default. The accepted standards for desktop applications declare that application logos / icons should be installed under $prefix/share/icons, so use this directory location. Pre-rendered icons are provided at the standard sizes expected for GUI applications, along with the scalable SVG, to ensure maximum portability. The PNGs are rendered from the SVG using inkscape, however, this is not wired up into the default make rules to avoid requiring inkscape as a mandatory tool in build systems / developer workstations.

2018-01-12sdl2: Ignore UI hotkeys after a focus change when GUI modifier is heldJindrich Makovicka1-8/+24
When SDL2 windows change focus while a key is held, the window that receives the focus also receives a new KeyDown event, without an autorepeat flag. This means that if a WM places the qemu console over the main window after Ctrl-Alt-2, the console closes immediately after opening. Then, the main window receives the KeyDown event again and the whole process repeats. This patch makes the SDL2 UI ignore the KeyDown events on a window that just received the focus, if the GUI modifier was held. The ignore flag is reset on a first KeyUp event. This effectively works around the issue above.

2017-05-23shutdown: Add source information to SHUTDOWN and RESETEric Blake1-2/+2
Time to wire up all the call sites that request a shutdown or reset to use the enum added in the previous patch. It would have been less churn to keep the common case with no arguments as meaning guest-triggered, and only modified the host-triggered code paths, via a wrapper function, but then we'd still have to audit that I didn't miss any host-triggered spots; changing the signature forces us to double-check that I correctly categorized all callers. Since command line options can change whether a guest reset request causes an actual reset vs. a shutdown, it's easy to also add the information to reset requests.

sdl 2.0.4 currently has a bug which causes our UI shortcuts to fire rapidly in succession: https://bugzilla.libsdl.org/show_bug.cgi?id=3287 It's a toss up whether ctrl+alt+f or ctrl+alt+2 will fire an odd or even number of times, thus determining whether the action succeeds or fails.

2015-12-17qapi: Change munging of CamelCase enum valuesEric Blake1-2/+2
When munging enum values, the fact that we were passing the entire prefix + value through camel_to_upper() meant that enum values spelled with CamelCase could be turned into CAMEL_CASE. However, this provides a potential collision (both OneTwo and One-Two would munge into ONE_TWO) for enum types, when the same two names are valid side-by-side as QAPI member names. By changing the generation of enum constants to always be prefix + '_' + c_name(value, False).upper(), and ensuring that there are no case collisions (in the next patches), we no longer have to worry about names that would be distinct as QAPI members but collide as variant tag names, without having to think about what munging the heuristics in camel_to_upper() will actually perform on an enum value. Making the change will affect enums that did not follow coding conventions, using 'CamelCase' rather than desired 'lower-case'. Thankfully, there are only two culprits: InputButton and ErrorClass. We already tweaked ErrorClass to make it an alias of QapiErrorClass, where only the alias needs changing rather than the whole tree. So the bulk of this change is modifying INPUT_BUTTON_WHEEL_UP to the new INPUT_BUTTON_WHEELUP (and likewise for WHEELDOWN). That part of this commit may later need reverting if we rename the enum constants from 'WheelUp' to 'wheel-up' as part of moving x-input-send-event to a stable interface; but at least we have documentation bread crumbs in place to remind us (commit 513e7cd), and it matches the fact that SDL constants are also spelled SDL_BUTTON_WHEELUP.

2015-12-17qapi: Don't let implicit enum MAX member collideEric Blake1-1/+1
Now that we guarantee the user doesn't have any enum values beginning with a single underscore, we can use that for our own purposes. Renaming ENUM_MAX to ENUM__MAX makes it obvious that the sentinel is generated. This patch was mostly generated by applying a temporary patch: |diff --git a/scripts/qapi.py b/scripts/qapi.py |index e6d014b..b862ec9 100644 |--- a/scripts/qapi.py |+++ b/scripts/qapi.py |@@ -1570,6 +1570,7 @@ const char *const %(c_name)s_lookup[] = { | max_index = c_enum_const(name, 'MAX', prefix) | ret += mcgen(''' | [%(max_index)s] = NULL, |+// %(max_index)s | }; | ''', | max_index=max_index) then running: $ cat qapi-{types,event}.c tests/test-qapi-types.c | sed -n 's,^// \(.*\)MAX,s|\1MAX|\1_MAX|g,p' > list $ git grep -l _MAX | xargs sed -i -f list The only things not generated are the changes in scripts/qapi.py. Rejecting enum members named 'MAX' is now useless, and will be dropped in the next patch.

2015-06-09sdl2: fix crash in handle_windowevent() when restoring the screen sizeAlberto Garcia1-0/+4
The Ctrl-Alt-u keyboard shortcut restores the screen to its original size. In the SDL2 UI this is done by destroying the window and creating a new one. The old window emits SDL_WINDOWEVENT_HIDDEN when it's destroyed, but trying to call SDL_GetWindowFromID() from that event's window ID returns a null pointer. handle_windowevent() assumes that the pointer is never null so it results in a crash.
