xlib

I am writing a simple programmes in C where i want to capture all the mouse and Keyboard events that are taking place. I tried to use "XGrabPointer" but it results in locking the screen and i can not go to other applications. I tried with "XSelectInput()" and now i am receiving the keyboard events successfully but i am not getting any mouse click events. Any idea how can i do it? The code snippet is as follows: #include <stdio.h> #include <stdlib.h> #include <X11/Xlib.h> #include <X11/Xutil.h> #include <X11/keysym.h> int main(int argc, char **argv) { Display *dpy; Window root; unsigned long

I want to make a click through window. A window which I click but the click pass to the window below it. I've found this two solutions for windows: How to make click-through windows PyQt I have a form that can "click through", i.e. direct clicks to the window below. How can I undo my changes after the event? But I want it to work in linux. I study the xlib mechanisms but cannot understand how the window stack works. Actually I can get all the windows with XQueryTree() and found the ones under my window. But I don't know witch one are above. 来源： https://stackoverflow.com/questions/30670032

as soon as i use display.grab_keyboard, no other window seems to know of its own focus. with the keyboardgrab running i can select other windows and even send keyevents to them, but if this window is a text input there will be no blinking cursor. i read something about grab_keyboard generating focusevents, but that doesnt mean it blocks all focus events, does it? what am i not getting here? from Xlib import X,XK from Xlib.display import Display import signal,sys root = None display = None def main(): # current display global display,root display = Display() root = display.screen().root root

I want to draw some primitives on top of all windows on the screen. I've found some code in C and tried to port it to use python's xlib: from Xlib.display import Display from Xlib import X from Xlib import protocol display = Display(':0') root = display.screen().root gc = root.create_gc() root.fill_rectangle(gc, 100, 100, 500, 500) But nothing appears on the screen (however, the root window is assigned: grabbing keyboard after it works). How to do this correctly? Andrey Sidorov You can draw on root window - your code probably works, but root window may be obscured by some kind of desktop

I want to find C / Xorg code to 'enter' a left mouse button click. I'd expect a single line of code but the only things I've found written in C are about two dozen lines long and they don't work anyway :( It seems it can be done in Windows, but I'm in Linux. The reason for the question is that I've written a utility that lets me move my mouse pointer between several screens using the keyboard. The only problem is that if I move to a location where window abc used to be but another window xyz has been loaded on top of that same location, the mouse pointer moves to xyz just fine, but xyz doesn't
