Urxvt Geometry

Does anyone know a way of specifying a geometry for urxvt in pixels? As opposed to characters.

Or alternatively, a way to easily convert between the two? I'm trying to implement something like how echinus allows you to "draw" terminals. Only I think echinus takes advantage of the fact that it's a window manager to do this. Whereas I have an X, Y, Width and Height to work with.

Re: Urxvt Geometry

~/.Xdefaults                                                                       
URxvt.geometry: 70x35

And some other changes i did

URxvt.saveLines: 10000
URxvt.scrollBar: false
URxvt.foreground: white
URxvt.background: black
URxvt.secondaryScroll: true
URxvt.font: xft:liberation mono:pixelsize=11

i hope that is what you are looking for...

edit...
i've just read that you search for "PIXELS"
sorry

Re: Urxvt Geometry

It seems that (X)characters = 8x(X) pixels and (Y) characters = 16x(Y) pixels, a urxvt -geometry 160x25 would take 1280 px width and 400 px height

Re: Urxvt Geometry

It depends on your font, of course. If you have a 9x16 font, you'll need to multiply your character number and the font width/height.

Ah ok I thought I might have to do this, thank you all for your input

Re: Urxvt Geometry

I got it

To use it you can make a script like this (launchterm.sh), replace the width and height with whatever you need for your font:

let WIDTH=$3/5
let HEIGHT=$4/10
urxvtc -g ${WIDTH}x${HEIGHT}+${1}+${2}  -e screen -x -R -p = &

And then compile this little app, which allows you to run different scripts when different mouse buttons are clicked on the root window:

/*
 * Run stuff on root window clicks
 * By HashBox
 */

#define RESOURCE_NAME "rootgrab"
#define MOUSE_BUTTONS 5

#include <X11/Xlib.h>
#include <X11/Xresource.h>

#include <stdlib.h>
#include <stdio.h>
#include <string.h>

int main()
{
    Display *dpy;
    XEvent ev;

    XrmDatabase db;
    XrmValue button[5];
    char xdb_path[128];
    char *type;

    int x, y, i;

    if (!(dpy = XOpenDisplay(NULL))) {
        fprintf(stderr, "Could not open display %s", getenv("DISPLAY"));
    }

    sprintf(xdb_path, "%s/.Xdefaults", getenv("HOME"));

    XrmInitialize();

    db = XrmGetFileDatabase(xdb_path);

    for (i = 1; i <= MOUSE_BUTTONS; i++) {
        char temp[24];

        sprintf(temp, RESOURCE_NAME".button%i", i);

        /* If a launch path is found for this button then grab this button so we get events for it */
        if (XrmGetResource(db, temp, temp, &type, &button[i-1])) {
            XGrabButton(dpy, i, 0, DefaultRootWindow(dpy), True, ButtonPressMask, GrabModeSync, GrabModeAsync, None, None);
        }
    }

    for (;;) {
        XNextEvent(dpy, &ev);

        if (ev.type == ButtonPress) {
            if (ev.xbutton.subwindow == None) { /* Root Window */
                /* Grab pointer so we receive ButtonRelease */
                XGrabPointer(dpy, DefaultRootWindow(dpy), True, ButtonReleaseMask, GrabModeAsync, GrabModeAsync, None, None, CurrentTime);
                x = ev.xbutton.x_root;
                y = ev.xbutton.y_root;
            }

            XAllowEvents(dpy, ReplayPointer, CurrentTime); /* Allow other apps to process this message */
        } else if (ev.type == ButtonRelease) {
            XUngrabPointer(dpy, CurrentTime);

            char shell_buff[256];

            /* If last character of launch path is '%' then tack some variables on */
            if (button[ev.xbutton.button-1].addr[strlen(button[ev.xbutton.button-1].addr)-1] == '%') {
                int start_x, start_y, width, height;
                width = ev.xbutton.x_root - x;
                height = ev.xbutton.y_root - y;

                /* Ugliness to make width/height positive and put the start positions
                 * in the right place so we can draw backwards basically. */
                if (width < 0) { width = abs(width); start_x = ev.xbutton.x_root; } else { start_x = x; }
                if (height < 0) { height = abs(height); start_y = ev.xbutton.y_root; } else { start_y = y; }

                sprintf(shell_buff, "%.*s %i %i %i %i &", strlen(button[ev.xbutton.button-1].addr)-1, button[ev.xbutton.button-1].addr, start_x, start_y, width, height);
            } else {
                sprintf(shell_buff, "%s &", button[ev.xbutton.button-1].addr);
            }

            system(shell_buff);
        }
    }

    XCloseDisplay(dpy);

    return 0;
}

And then place something like this in your .Xdefaults (Draw terminals with left button, display menu on right click, and scroll up/down to change volume):

rootgrab*button1: launchterm.sh%
rootgrab*button3: rootmenu.sh%
rootgrab*button4: amixer -q sset Master 1+
rootgrab*button5: amixer -q sset Master 1-

The "%" at the end of the first two scripts indicates that the app should pass $X $Y $WIDTH $HEIGHT as parameters when launched.

EDIT: Updated the code a bit
