In Mac 10.9.4 I'm seeing for every key event the message:

Failed to signal RunLoop main!

Due to CFRunLoopCopyCurrentMode returning NULL, which from the docs means that the main loop is not running although at least CFRunLoopRun is blocking on the other thread.

CFStringRef mode = CFRunLoopCopyCurrentMode(CFRunLoopGetMain());
CFRunLoopGetMain() -> 0x7f8d3ca00100, mode 0x0
CFRunLoopCopyCurrentMode(CFRunLoopGetMain()) -> mode 0x0

This is just affecting the key typed detection but it is annoying nevertheless ;)

Before El Capitain (10.11) the property was:
defaults read com.apple.universalaccess mouseDriverMaxSpeed
(values range 1-32 (slow-fast)).

But now it is:
defaults read NSGlobalDomain com.apple.mouse.scaling
values appears to be between 0.0-3.0 (slow-fast)

Original:kwhat/jnativehook#110

Following the negative coordinates, the issue also occurs into the other screen direction, reporting values higher than the maximum resolution itself. For now I'm dealing with this on the application side as I wanted to avoid having static values for the resolution and/or retrieving the resolution for every event (at least not till I've done some profiling). So I thought I would let you know anyways :)

ARM-based devices running Windows currently require 32-bit (x86) builds.

When using libuiohook in this environment (I'm testing against ia32 architecture on win32) pVkToWcharTable is null when accessed within input_helper. I believe this is due to an issue with pointer sizes.

This Stackoverflow post seems related to what's happening here. The answer indicates that utilizing the original kbd.h would work in 32-bit environments.

I did manage to populate pVkToWcharTable by making changes to input_helper.h using the original definitions fromkbd.h, but it seems there needs to be further changes inside keycode_to_unicode to accommodate a 32-bit environment.

I hope helps. This is a bit outside my competency, but I'm happy to test and provide feedback.

hi,
Now that I got it working on windows, I'm back to trying on arch linux. However, when I run make (no configure errors this time, whew), it gives the following output:

I have two keyboards attaches to my Windows 7 computer.
Is it possible to know which keyboard sends the input when a keyboard event triggers.

I really need this function in my project.
Can anyone help me out with this.
Thanks a lot

I tried to compile the project on a Mac OSX 10.9.3 and got an error at:
https://github.com/kwhat/libuiohook/blob/master/src/darwin/input_helper.c#L307

make: *** [src/darwin/libuiohook_la-input_helper.lo] Error 1

VC_HELP is not contained in

I managed to resolve the error by inserting VC_HELP into uiohook.h
#define VC_HELP 0x0072

The 0x0072 is just a bogus value since I have no clue what a Help-keycode on a Mac is nor if a help-key even exists.

Hi @kwhat

I would like to use your library from a golang application. I have no knowledge of C so I have extracted the the compiled version of this library from the jnativehook.jar file. However, to use them I need the related header files and I don't which one to use. Could you please help me identifying the correct ones?

Hi,

I don't actually have "real" issue with this (great!) lib, but rather a request if anyone has a simple working QT application with dynamic binding available?

I am unable to get it working with my QT app :-(

I "borrowed" the code from the example and only

// Set the logger callback for library output.
hook_set_logger_proc(&logger_proc);
// Set the event callback for uiohook events.
hook_set_dispatch_proc(&dispatch_proc);

do work, while the following

hook_run()

makes my program crash. The last log output I get is:

"%s [%u]: hInst was not set by DllMain().\n"

(with vars filled in, of course).

Anyone a hint for me?

Thanks a lot!

I'm not sure if master is supposed to be compilable, 1.0 seemed to have same issue?

This is the output of ./bootstrap ./configure and make
I have all the requirements and the OS is 14.04.02 LTS Ubuntu (I also tried on my local Arch Linux install but it had the same error) I'm able to get the branch you use for Jnativehook to compile.

When a keyboard event is handled a deadlock occurs on:
https://github.com/kwhat/libuiohook/blob/master/src/darwin/hook_callback.c#L221

I set up a small sample application in XCode to verify. Mouse events are handled well, but as soon as I hit any key on the keyboard the application doesn't output any further event logs any more.

Traced down to a deadlock in the handling procedure for keyboard events - possibly because a mutex is locked two times and never gets unlocked afterwards. When I pause the application in the debugger it shows a thread waiting at this line for the mutex to be unlocked.

I'm running a MacBook Air on OSX Maverix 10.9.3

Keep up the great work, I'm really glad I found this project :)

Thanks!

I can't find way to prevent event. Can libuiohook do it?
Will be cool prevent event after receiving (optionally)

I am using the 1.1 branch, build fails on MacOS 10.15

I ran the following commands:

So, I have been trying to trace the problem I have been having with jnativehook.

I'm actually trying to compile jnativehooks for use with java but this library is preventing the process. Any help would be appreciated as it seems you have a great library that I would love to try using.

It's common practice to include a void* argument in callback registers and then return it in the callback to allow the application to get back to their class or struct that should handle the callback. Without it, the application is forced to use global state to manage the callback, which is less nice to work with.

IMO this would be a nice thing to add whenever the API is next updated.

Hello,

I'm facing some problems on Windows ( i didn't test on other platform yet). some keys doesn't trigger KEY_TYPED event. I'm talking here about PageUp/PageDown, Del/Insert, Home/End and F1,F2,... function keys.

KEY_RELEASED and KEY_PRESSED work correctly.

Regards,

When USE_XKB is not defined in config.h, them related headers are not included, for example in input_hook.c:

#ifdef USE_XKB
#include <xcb/xkb.h>
#include <X11/XKBlib.h>
#endif

However, if they are not included the compilation fails:

I am using the Node package iohook which leverages libuiohook. The original issue was here for context. However, now that I can run iohook on the UDOO Quad ARM computer locally when run from the terminal on the physical machine, I cannot run iohook when invoking the app from a remote computer via SSH.

I was told this was an libuiohook issue so here I am.

The usage example iohook provides works when run from the terminal on the actual machine with a monitor, keyboard and mouse.

However, when disconnecting the monitor and keyboard (and even with them connected) and SSHing into the UDOO, I get this when running the usage example:

on_library_load [456]: XOpenDisplay failure!
load_input_helper [1907]: XkbGetKeyboard failed to locate a valid keyboard!
PID 7608 received SIGSEGV for address: 0x94
Error: Couldn't find per display information

Also, the intent is for this to be run on an UDOO Quad without a monitor or mouse connected, just a USB button which essentially acts as a keyboard.

Doing the reverse and SSHing into my Mac from the UDOO, I am able to run the usage example remotely on my Mac and press the USB button connected to the Mac and get the keyup event. However, doing the opposite and SSHing into my UDOO from the Mac and running the usage example provides the above error. Any ideas?

Per "input_helper.h", I'm filing a bug report because Visual Studio 2013 Community Edition (_MSC_VER == 1800) does not define LPFN_ISWOW64PROCESS.

Is there a plan to add touch event support ? Thanks very much.

Mac media key events such as mute, volume up/down, play, etc are currently not detected.

However, there is way to do so:

Hi,
I am using allegro to get keyboard input, and really all I wanted was to get a keyboard hook on all platforms (as I am making mainly audiogames, aimed at the blind, and some screen readers, namely jaws for windows, hog the keyboard unless turned off, or an application specific hook set to override its hook). However, when I run my program with libuiohook installed, I get a bunch of log messages (btw, how to make those go away?), and allegro doesn't get any keyboard input. Any way to make allegro play nice with libuiohook?
Thanks,
-Michael.

I tried to configure project using CMake but it seem that config.h.in not found.

Hi,

I have been working with libuiook in linux for a while now, firts fo all thanks for making this great lib.

However, I need to make it run in windows, but I'm having problems installing libuiohook in windows.

This it's what I've done so far:

I install MinGW and MSYS2 and follow the step in this link

https://github.com/kwhat/jnativehook/wiki/Compiling.

After that I continue with:
./bootstrap.sh
./configure
make && make install

Everything work perfectly until the last step make && make install, when I got this error:

make: *** [src/windows/libuiohook_la-input_hook.lo] Error 1

I really have no idea what could be caussing this error, I'm using the 1.0 version of the libuiohook.

Any idea of what could be caussing this error ??

Not really a bug, but someone's using my obs-studio plugin, which loads libuiohook together with another piece of software that also uses the library (restream chat) and it causes the mouse input to slow down to a crawl.
The restream program is a node app, which doesn't have public source, but I just assume they used this version of libuiohook.

I've seen the behavior when launching two instances of the async demo. Just wondering if there's anything that I can do on my side to prevent this from happening or if there's no way to have two instances of the hook running in parallel.

Most of the posted issues are compiling process related.
Maybe we could use something like Travis (https://docs.travis-ci.com/user/getting-started/ | https://docs.travis-ci.com/user/languages/cpp/) to automatically built the binaries on each release and attach them in releases page section (https://github.com/kwhat/libuiohook/releases)

Since hook_run blocks the thread until stop is called, the only places hook_stop can be called on the same thread are in callbacks, which is what the two demos do. If an application wants to to stop hook on demand though, relying on user input to cause a callback while trying to shutdown seems unreliable.

Alternatively calling hook_stop from an outside thread looks unsafe since hooks API are not thread safe. This might not be that bad in practice since hook_run looks like it will be blocked on other library calls and not accessing its structure data after startup, but this still doesn't give any guarantees of thread safety.

A possible workaround might be to stop from the callback and inject an event from the application to force a callback, but this seems pretty convoluted.

I think the API would be easier to work with if hook_run was called periodically from the application and returned, instead of being called once and blocking, allowing the application to call other API in between checking for new keys.

How to reproduce error:

1. set keyboard layout to Spanish

5. change keyboard layout to Arab
6. write in notepad windows: the same key in keyboard (A)

(Compiled in Windows 7 x64 with MSYS64 + MINGW64)

Looks like event EVENT_KEY_TYPED never fires in macOS Sierra 10.12.
I try my project on Ubuntu 16.04 works fine but in macOS this event never fires,
but EVENT_KEY_PRESSED and EVENT_KEY_RELEASED working great

I'm trying to install JnativeHook, and during the installation process it must install libuihook, and I've installed all the prerequisites of JNativeHook and libuihook (I think so).

After so many attempts, finally the compilation began and failed again. I don't know what more to do, I will let a screenshot here

Hi,

While compiling on Windows 7, mingw32 4.8.1, I get undeclared variables and functions errors:

EVENT_OBJECT_NAMECHANGE
WINEVENT_OUTOFCONTEXT
WINEVENT_SKIPOWNPROCESS
...
SetWinEventHook
UnhookWinEvent

I had to define WINVER macro in input_hook.c in order to compile successfully.

#ifndef WINVER
    #define WINVER 0x0500
#endif

I had to install the following unlisted dependencies in order to get ./configure to not error

xtst
xkbcommon-x11
xkbfile

The demo program failed to build on macOS with error

error: use of undeclared identifier 'wint_t'

I was able to fix the error and compile successfully by including wchar.h in demo_hook.c

Hi,
I was just trying to compile libuiohook for a project I'm working on, and based on a comment to an issue on jninativehook, I needed to use msys2. I installed the packages mentioned in the issue, and did autoconf. The following output resulted:

configure.ac:59: error: possibly undefined macro: AM_INIT_AUTOMAKE
If this token and others are legitimate, please use m4_pattern_allow.
See the Autoconf documentation.

I tried automake, but it said to run autoconf again.

Hello!
First of all, thanks for the great library!
I'm trying to use libuiohook with simple Qt program under OS X.
And sometimes the library starts sending EVENT_KEY_TYPED constantly.
As the result my program freezes.
I can't reproduce this bug in demo_hook app, but in my Qt app the problem arise regularly.
Here is how I'm using the library: (http://ns35.ru/tmp/hooks.cpp)
I'm starting it in separate thread.
And some logs:
(http://ns35.ru/tmp/log_failed.txt)
(http://ns35.ru/tmp/log_failed2.txt)
(http://ns35.ru/tmp/log_failed3.txt)
(http://ns35.ru/tmp/log_normal.txt)
When I had removed lines 327-395 in /libuiohook-master/src/darwin/input_hook.c the problem gone.
The problem reproduced in master and 1.0 branches, in OS X 9 and OS X 10, in debug and release library builds. The problem persists in builds with --disable-corefoundation and --disable-iokit.
I solved my problem because I don't need EVENT_KEY_TYPED messages, but I report anyway in case this would help somebody.

If being run in a headless environment, e.g. through ssh or with an application that's being unit tested on a CI server, libuiohook causes a segfault during library load:

Program received signal SIGSEGV, Segmentation fault.

If this registration could be delayed until hook_run or a new setup API is called, then the application could choose to not start hook and avoid the call. As it is now, the application has to avoid linking hook, and instead load the library from code once it's verified that there's a normal display present.

Anyone knows why I got the following error while trying to build and run it from CLion IDE?

Hey @univrsal,

Could you please test c980b18, I made a few changes to fix these "function called through a non-compatible type" and "if this code is reached, the program will abort" warnings I was seeing. I think the changes should be okay, but I want to confirm on newer versions of OS X.

Thanks!

I am dropping any plans on supporting CMake for this project. I have tried for the past week to get something building and it is far I have been unsuccessful. Working with CMake has been exceptionally painful for this project and the vague documentation is not doing me any favors. If you really want CMake support than please take a look at the cmake branch and see if you can get it working. No integration will take place until Windows, Linux and OS X successfully build with CMake and I will not be wasting any more of my time trying to get it working as there are many other issues to address.

is this a paste error in libuiohook/src/darwin/post_event.c line 38 ? did you mean kCGEventFlagMaskCommand ?

Also on mac i had to comment out these lines at the end of the initialize_Modifiers function to make it work ( libuiohook/src/darwin/input_hook.c line 185):

// if (CGEventSourceFlagsState(kCGEventFlagMaskAlphaShift)) {
// set_modifier_mask(MASK_CAPS_LOCK);//ols: the hook doesn't start if this is called
// }
// Best I can tell, OS X does not support Num or Scroll lock.
//unset_modifier_mask(MASK_NUM_LOCK);
//unset_modifier_mask(MASK_SCROLL_LOCK); //ols: strange, but this sets both bits to 1

This lib is super useful. thanks for your work

Hi,
we tray integrate libuiohook with Qt app and when we run app and close is we have error:
get_keyboard_layout_file [455]: RegOpenKeyEx failed to open key: "SYSTEM\CurrentControlSet\Control\Keyboard Layouts\0"!
21:07:19: The program has unexpectedly finished.
21:07:19: The process was ended forcefully.

Can you tell me what is problem. We test on win 10 and win 7 not different.
I use: demo_hook_async.c

Thanks!

Thanks to the author for creating this library. I found a problem in the new apple system, which will block the system after my application has been running for some time.

Windows mouse coordinates need to be normalized as due to MOUSEEVENTF_ABSOLUTE (1)
If MOUSEEVENTF_ABSOLUTE value is specified, dx and dy contain normalized absolute coordinates between 0 and 65,535. The event procedure maps these coordinates onto the display surface. Coordinate (0,0) maps onto the upper-left corner of the display surface; coordinate (65535,65535) maps onto the lower-right corner. In a multimonitor system, the coordinates map to the primary monitor.

I'll split the issue in two versions as for the single monitor version the fix is straightforward.

Single monitor:
It can be easily fixed by normalizing the coordinates this way:

double fScreenWidth   = GetSystemMetrics( SM_CXSCREEN )-1; 
double fScreenHeight  = GetSystemMetrics( SM_CYSCREEN )-1;
...
events[events_size].mi.dx = event->data.mouse.x * (65535.0f/fScreenWidth);
events[events_size].mi.dy = event->data.mouse.y * (65535.0f/fScreenHeight);
...
events[events_size].mi.dx = event->data.wheel.x * (65535.0f/fScreenWidth);
events[events_size].mi.dy = event->data.wheel.y * (65535.0f/fScreenHeight);

Multiple monitor:
We need to know to which monitor the coordinates x,y belong to in order to make the conversion properly as it depends on the monitor resolution (in case they are non-uniform).

So from post_event we need access to the monitor enumerator or to a valid screen_info structure.

P.S. I'll be also opening a ticket for the hook_create_screen_info (as you were done with it already?)

Hi,
I read that visual studio 2015 has c99 support, and I even managed to compile libuiohook on it (using the command line). I was just thinking that perhaps an official project could be provided in the git repo now that visual studio does support c99.

Hi Alex Barker (@kwhat), I have one problem with deadkeys support.

Some keys works fine, for example: ?¿@{} -> The keychar is correct: id=3,when=15251484,mask=0x1,keychar=?,rawcode=219

But when I try with a deadkey + letter dont works. For example: Á

id=4,when=16440134,mask=0x0,keycode=40,rawcode=0xDE
id=5,when=16440196,mask=0x0,keycode=40,rawcode=0xDE
id=4,when=16440258,mask=0x0,keycode=30,rawcode=0x41
id=3,when=16440258,mask=0x0
id=5,when=16440336,mask=0x0,keycode=30,rawcode=0x41

It only logs A (0x41) without UTF-16 composition.
