Hello, I am creating a sort of window manager in bash and in C and I would like to create shortcuts for my application with the Xlib, but I have some troubles to do it ...
I need to make 2 different shortcuts :
SUPER + ALT_L + letter SUPER + letter
The first one functions when I type SUPER, then Alt and finally the letter. But it doesn't functions when I begin by typing ALT_L .... And the 2° doesn't functions ...
I don't really know what to do ... Could you help me ? (please, sorry for the possible mistakes in English, I am french)
Here is what I have done :
#include <stdlib.h>
#include <stdio.h>
#include <string.h>
#include <X11/Xlib.h>
GC gc; // Contexte graphique
Display* display;
int screen;
Window root;
void swallow_keystroke(Display * dpy, XEvent * ev)
{
XAllowEvents(dpy, AsyncKeyboard, ev->xkey.time);
}
void passthru_keystroke(Display * dpy, XEvent * ev)
{
/* pass it through to the app, as if we never intercepted it */
XAllowEvents(dpy, ReplayKeyboard, ev->xkey.time);
XFlush(dpy);
}
int main(int argc, char* argv[]){
char cwd[1024];
getcwd(cwd, sizeof(cwd));
// Connexion à un serveur X
display = XOpenDisplay(NULL);
if(!display){
printf("Can not open display.\n");
exit(EXIT_FAILURE);
}
// Récupère la valeur par default des différentes variables.
screen = DefaultScreen(display);
gc = DefaultGC (display, screen);
root = RootWindow (display, screen);
// Gestion des évènements
