EVIL WINDOWS KEY

This document describes how to hack evilwm so it uses the
-evil- windows key present in 99% of PC keyboards to cycle
through windows. Based on this information, you can hack
further evilwm and assign actions to the right windows key
and to the menu key.

First, you have to discover which is the keycode of this
key. In most systems it should be 115. However, you can run
the following program which will print out the keycode of
each key pressed in the tiny window it creates.

The program is compiled with:
gcc -lX11 -L /usr/X11R6/lib you_name_it.c

----------------------------------------------------------------
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <X11/Xlib.h>
#include <X11/Xutil.h>
#include <X11/keysym.h>
#include <X11/Xatom.h>

int main ()
{
	Display *D;
	Window W;
	if (!(D = XOpenDisplay (NULL))) return -1;

	XSetWindowAttributes attr;
	attr.backing_store = Always;
	W = XCreateWindow (D, DefaultRootWindow (D), 0, 0, 200, 200, 1,
			   CopyFromParent, CopyFromParent, CopyFromParent,
			   CWBackingStore, &attr);

	XMapWindow (D, W);
	XFlush (D);
	XSelectInput (D, W, KeyPressMask);
	XEvent event;

	for (;;) {
	XNextEvent (D, &event);
	switch (event.type) {
	case KeyPress:
		printf ("KEY PRESS %i!!\n", event.xkey.keycode);
	}
	}
}
----------------------------------------------------------------

When you find the keycode of the left windows key, edit your
.xinitrc (or whichever file you use to start evilwm) and add
the following entry:

xmodmap -e "keycode 115 = F13"

This will make the windows key act as function key F13.

Then you have to hack evilwm to make it cycle through windows
when F13 is pressed.

1) Edit the file keymap.h and change:
-#define KEY_NEXT  XK_Tab
+#define KEY_NEXT  XK_F13

2) Edit the file main.c and change:

-	grab_keysym(screens[i].root, Mod1Mask, XK_Tab);
+	grab_keysym(screens[i].root, 0, KEY_NEXT);

Then "make clean; make" and 
Voila!!!!!!!!!!!!!!!!!!!


CENTERING THE WINDOWS

Ok, so you have a 800x600 screen but the virtual screen is actually
1600x1200 and when you cycle to the next window the pointer goes at
the bottom right corner and 99% of your window is out of screen.

Hack evilwm to include the entire window in the screen.
Edit the file screen.c
Find the line:
	
	setmouse(newc->window, newc->width + newc->border - 1,
		newc->height + newc->border - 1);

Just above this one add the line:

	setmouse(newc->window, 0, 0);

and "make clean; make".
