# Xwinwrap
|
||||
|
||||
My fork of xwinwrap.
|
||||
Xwinwrap allows you to stick most of the apps to your desktop background.
|
||||
My use case - can use gif as a background
|
||||
|
||||
### Compiling
|
||||
|
||||
`gcc -Wall xwinwrap.c -lX11 -lXext -lXrender -g -o xwinwrap`
|
||||
|
||||
You may have to use `-L` flag to specify directory for xlib.
|
||||
e.g. `gcc -Wall xwinwrap.c -L /usr/lib/x86_64-linux-gnu -lX11 -lXext -lXrender -g -o xwinwrap`
|
||||
|
||||
### Usage
|
||||
|
||||
```
|
||||
Usage: xwinwrap [-g {w}x{h}+{x}+{y}] [-ni] [-argb] [-fs] [-s] [-st] [-sp] [-a] [-b] [-nf] [-o OPACITY] [-sh SHAPE] [-ov]-- COMMAND ARG1...
|
||||
Options:
|
||||
-g - Specify Geometry (w=width, h=height, x=x-coord, y=y-coord. ex: -g 640x480+100+100)
|
||||
-ni - Ignore Input
|
||||
-argb - RGB
|
||||
-fs - Full Screen
|
||||
-un - Undecorated
|
||||
-s - Sticky
|
||||
-st - Skip Taskbar
|
||||
-sp - Skip Pager
|
||||
-a - Above
|
||||
-b - Below
|
||||
-nf - No Focus
|
||||
-o - Opacity value between 0 to 1 (ex: -o 0.20)
|
||||
-sh - Shape of window (choose between rectangle, circle or triangle. Default is rectangle)
|
||||
-ov - Set override_redirect flag (For seamless desktop background integration in non-fullscreenmode)
|
||||
-debug - Enable debug messages
|
||||
```
|
||||
Example
|
||||
`./xwinwrap -g 400x400 -ni -s -nf -b -un -argb -sh circle -- gifview -w WID mygif.gif -a`
|
||||
|
||||
### Changes
|
||||
|
||||
* Added ability to make undecorated window
|
||||
* Changed how desktop window is found
|
||||
* Refactored window hints
