I am trying to open an X11 window, print out one pixel, and then later add code to make Terminate() return true. But it won't make a window. Here is my code:
#include <X11/Xlib.h>
#include <X11/Xutil.h>
#include <X11/Xos.h>
#include <iostream>
int x = 0;
int y = 0;
bool Termination() {
return true;
}
int main() {
Display *dspl = XOpenDisplay(NULL);
if (!dspl) return 1;
int screenNumber = DefaultScreen(dspl);
unsigned long white = WhitePixel(dspl, screenNumber);
unsigned long black = BlackPixel(dspl, screenNumber);
Window win = XCreateSimpleWindow(dspl, DefaultRootWindow(dspl), 50, 50, 1280, 720, 0, black, white);
XSetStandardProperties(dspl, win, "Lel", "Gaem", None, NULL, 0, NULL);
GC gc = XCreateGC(dspl, win, 0,0);
XSetBackground(dspl, gc, black);
XSetForeground(dspl, gc, white);
XClearWindow(dspl, win);
XMapRaised(dspl, win);
XDrawPoint(dspl, win, gc, x, y);
while (Termination())
{
}
XFreeGC(dspl, gc);
XDestroyWindow(dspl, win);
XCloseDisplay(dspl);
printf("Job's done!\n");
return 0;
}
What's keeping X11 from making my window appear?
add this before the while
XMapWindow(dspl, win);
XInternAtom(dspl, "WM_DELETE_WINDOW", False);
