* Fix Xfixes event handlingUlrich Sibiller2021-07-051-53/+48
| | | | | | | | | Calling the callback on receptions of an EXTERNAL xfixes event was a weird idea from the start. However, since adding the protection trap around it it made no sense at all because it effectivly made the callback a noop for that case. So let's drop all the trap nonsense and implement it properly. The callback will only be used for actions by internal clients.
* Events.c: fix unused variableUlrich Sibiller2021-06-201-1/+4
|
* Clipboard.c: rework nxagentFind*SelectionIndex() helpersUlrich Sibiller2021-06-201-1/+1
| | | | Let them return -1 which makes it easier to check for successful execution.
* Events.c: use already available variable instead of repeating conversionUlrich Sibiller2021-06-201-1/+1
|
* Events.c: use index instead of iUlrich Sibiller2021-06-201-7/+7
| | | | we do that everywhere when handling clipboard stuff
* Clipboard.c: improve function names once moreUlrich Sibiller2021-06-201-1/+1
|
* Clipboard.c: rework LastClient stuff to work _per selection_Ulrich Sibiller2021-06-201-7/+1
|
* Forward ClientMessages to nxproxy sideUlrich Sibiller2021-06-071-0/+64
| | | | | | | | | | | | This should help with clients requesting window manager actions like maximizing or minimizing. This is a first version as it only handles messages of type WM_STATE_CHANGE and _NET_WM_STATE. But ICCCM and EWMH know some more. The other direction, setting of properties by the WM, is already implemented in Rootless.c. Fixes ArcticaProject/nx-libs#1015
* nxagent: drop unused nxagentVisibility variablesUlrich Sibiller2021-01-301-2/+0

* nxagent: make nxagentForceSynchronization a BooleanUlrich Sibiller2021-01-151-1/+1
|
* nxagent: handle RegionNil macro as BooleanUlrich Sibiller2021-01-151-1/+1
| | | | just as the rest of the Xserver is alsow doing
* nxagent: rework some Boolean checksUlrich Sibiller2021-01-151-2/+2
| | | | | nxagentWindowTopLevel() and nxagentNeedConnectionChange() return Boolean nxagentPixmapIsVirtual() and nxagentIsShmPixmap(), too.
* nxagent: make nxagentShadowResize a BooleanUlrich Sibiller2021-01-151-1/+1
|
* nxagent: make nxagentVerbose a BooleanUlrich Sibiller2021-01-151-1/+1
|
* nxagent: make Desktop, Rootless and Binder options Booleans (again)Ulrich Sibiller2021-01-151-6/+6
| | | | | They have been changed to tri-state variables (1, 0 and UNDEFINED) between nxagent 1.5.0-90 and -93, for no obvious reason.
* nxagent: make nxagentOption Shadow a BooleanUlrich Sibiller2021-01-151-7/+7
| | | | and add the missing init code.
* nxagent: treat several nxagentOptions as real BooleansUlrich Sibiller2021-01-151-9/+9
| | | | | | | Adaptive, Composite, DeviceControl, DeviceControlUserDefined, IgnoreVisibility, InhibitXkb, Nested, Menu, MagicPixel, Persistent, Reset, ResetzKeyboardAtResume, SharedMemory, SharedPixmaps, Streaming, UseDamage, ViewOnly, Xdmcp, Xinerama
* nxagent: treat DesktopResize and nxagentResizeDesktopAtStartup as BooleansUlrich Sibiller2021-01-151-5/+5
| | | | The already where Booleans but where not using True/False values everywhere
* nxagent: make Fullscreen and AllScreens BooleansUlrich Sibiller2021-01-151-9/+9
| | | | | There's no need/sense in having a tri-state with the third state being UNDEFINED.
* Events.c: fix leftover DEBUG and TEST definitionsUlrich Sibiller2020-12-031-4/+1
| | | | causing DEBUG output in regular builds.
