moveresize

Description

This changes allows you to move and resize dwm's clients using keyboard bindings.

Usage

  1. Put the following moveresize() function somewhere in your dwm.c,

after the line which includes the config.h file:
static void 

moveresize(const Arg *arg)
{
	XEvent ev;
	Monitor *m = selmon;
	
	if(!(m->sel && arg && arg->v && m->sel->isfloating))
		return;
	
	resize(m->sel, m->sel->x + ((int *)arg->v)[0],
		m->sel->y + ((int *)arg->v)[1],
		m->sel->w + ((int *)arg->v)[2],
		m->sel->h + ((int *)arg->v)[3],
		True);
	
	while(XCheckMaskEvent(dpy, EnterWindowMask, &ev));
}


2. Add a moveresize() function definition in dwm.c below the line: 

static void movemouse(const Arg *arg);

static void moveresize(const Arg *arg);


3. Insert the bindings into the keys list. Here is an example which uses the arrow keys to move (mod+arrow) or resize (mod+shift+arrow) the selected client:

{ MODKEY,					XK_Down,	moveresize,		{.v = (int []){ 0, 25, 0, 0 }}},
{ MODKEY,					XK_Up,		moveresize,		{.v = (int []){ 0, -25, 0, 0 }}},
{ MODKEY,					XK_Right,	moveresize,		{.v = (int []){ 25, 0, 0, 0 }}},
{ MODKEY,					XK_Left,	moveresize,		{.v = (int []){ -25, 0, 0, 0 }}},
{ MODKEY|ShiftMask,			XK_Down,	moveresize,		{.v = (int []){ 0, 0, 0, 25 }}},
{ MODKEY|ShiftMask,			XK_Up,		moveresize,		{.v = (int []){ 0, 0, 0, -25 }}},
{ MODKEY|ShiftMask,			XK_Right,	moveresize,		{.v = (int []){ 0, 0, 25, 0 }}},
{ MODKEY|ShiftMask,			XK_Left,	moveresize,		{.v = (int []){ 0, 0, -25, 0 }}},

If you want to automatically toggle the client floating when move/resize, replace the if() statement above with this code:

if(!(m->sel && arg && arg->v))
	return;
if(m->lt[m->sellt]->arrange && !m->sel->isfloating)
	togglefloating(NULL);

Multi-head

From dwm 6.0 onward there's the following patch which is aware of the screen sizes in a multi monitor setup. A second patch allows you to maximize windows.
