* Splash.c: drop return code of nxagentShowSplashWindowUlrich Sibiller2019-08-272-5/+3
| | | | nobody was checking it.
* Splash.c: do not wait in nxagent modeUlrich Sibiller2019-08-273-17/+20
| | | | | | | The splash window is only shown in x2go mode. In nxagent mode the splash window was also shown, but empty (and thus invisible). And the code waited for the splash window to disappear. Fix this by skipping _all_ the splash stuff in nxagent mode.
* dix: add whiteroot flagUlrich Sibiller2019-08-272-3/+6
| | | | | | | | | | | | | | | | | Before there was no way of getting a white background despite having the approriate code. Backport of this commit: commit cb0a565d2b2cf8823abbd77b4426cc2237731dc1 Author: Daniel Stone <daniel@fooishbar.org> Date: Fri Aug 18 17:04:48 2006 +0300 dix: add whiteroot flag Add a -wr option to use a white root window, and use a BackPixel rather than BackPixmap for both white and black root windows. Fixes ArcticaProject/nx-libs#832
* NXwindow.c: simplify window background codeUlrich Sibiller2019-08-271-8/+4

* nxagent: fix main window being garbled without inner windowsUlrich Sibiller2019-08-271-2/+0
| | | | Fixes ArcticaProject/nx-libs#733
* nxagent: simplify nxagentWaitEvents()Ulrich Sibiller2019-08-167-35/+28
| | | | | no more need to pass down a struct, we now only pass the milliseconds and let the function do the rest.
* Keystroke.c: fix wrong return codeUlrich Sibiller2019-08-161-1/+4
| | | | | | The effect of this was that special keystrokes where detected and passed to the nxagent. E.g. pressing ctrl-alt-f for Fullscreen also produced an "f" in the current input window inside the nxagent.

* drop onscreen keyboard supportUlrich Sibiller2019-06-272-75/+1
| | | | | | | | | With the removal of the Ipaq code there's no path anymore to open the onscreen keyboard. Also nxkbd is not available and we do not have tested that feature with any onscreen keyboard yet. So there's no point in integrating that code. Fixes ArcticaProject/nx-libs#405

| | | | Did we ever provide a binary?
* Screen.c: use XlibWindow so silence the compilerUlrich Sibiller2019-06-271-2/+2
| | | | | | | | | | | | | | This is a bit weird, I'd expect far more places where the compiler could complain about Window vs Window64... But it does not.

* nxagentMaximizeToFullScreen: only reparent if necessaryUlrich Sibiller2019-06-271-21/+56
| | | | | | | | This fixes problems with kwin and compiz when using the switch-all-screens keystroke. The fullscreen would appear shortly and then vanish again. Fixes ArcticaProject/nx-libs#458

* rework xkb device private handlingUlrich Sibiller2019-06-222-16/+0
| | | | | | | We can only free the xkbDevicePrivate because we do not know the details of any other (possible) extension. So let's limit to that one private for now and call the new xkbFreePrivates from dix (where such a function is completely missing).

* compext/Png.c: late image_index allocationUlrich Sibiller2019-06-221-17/+18
| | | | | | | | Move allocation of image_index close before first_use. This way we do not need to free it if previous step fail. And we cannot forget that free() call. While at it replace malloc+memset by calloc.

* Keyboard.c: nullify freed pointersUlrich Sibiller2019-06-191-7/+11
| | | | | | | While trying to properly free memory allocated by XKB I accidently called nxagentFreeKeyboardDeviceData twice and noticed it would cause a segfault here. As the other pointers are also nullified after being freed let's just do it here, too.
* Screen.c: Fix: make sure RRCloseScreen is being calledUlrich Sibiller2019-06-191-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | Fixes ArcticaProject/nx-libs#598 In nxagentOpenScreen we first initialized the RRExtension for the screen and then replaced pScreen->CloseScreen by nxagentCloseScreen. This resulted in RandR's RRCloseScreen (and any other CloseScreen procedure installed by extensions) being no longer called. Moving RandR init after configuring pScreen->CloseScreen ensures the correct calling cascade: RRCloseScreen -> nxagentCloseScreen ->fbCloseScreen (called explicitly by nxagentCloseScreen). Which in turn will fix this memory leak: ==9688== 328 (312 direct, 16 indirect) bytes in 1 blocks are definitely lost in loss record 271 of 319 ==9688== at 0x4837B65: calloc (vg_replace_malloc.c:752) ==9688== by 0x4ED2C6: RRScreenInit (randr.c:329) ==9688== by 0x1F2B18: nxagentInitRandRExtension (Extensions.c:122) ==9688== by 0x1DEAFF: nxagentOpenScreen (Screen.c:1409) ==9688== by 0x16D7F8: AddScreen (dispatch.c:4257) ==9688== by 0x1DA0CF: InitOutput (Init.c:397) ==9688== by 0x14DCC2: main (main.c:280)
