Detecting maximized window(s) is this possible?

1.) I moved all user setting to the top of the script.

2.) I added session detection the script will only run in Unity 3D.

3.) I added detection if the script is already running when login occurs. If it detects script that was left from login out of Unity 3D and login in again it closes it and starts new one. If it detects script that was left from login out of Unity 3D and login in other session than Unity 3D it closes the running script and it does not start another one.

4.) I added both Hud and Dash exceptions so they won't interfere with the script anymore!

Code:

#!/bin/bash
# Install wmctrl before using: sudo apt-get install wmctrl


# Change settings
DELAY="2" # Set delay

SHOW_X="X" # Use wmctrl -lpG and find max X Y values when launcher is in never hide mode
SHOW_Y="Y" 

HIDE_X="X" # Use wmctrl -lpG and find max X Y values when launcher is in autohide mode
HIDE_Y="Y"

SCRIPT_PATH="/home/user_name/launcher.sh" # Change path


# End of user settings
ps -ef | grep "$SCRIPT_PATH" | grep -v "grep\|$$\|/bin/sh" | awk '!/awk/ {print $2}' | xargs -r kill

if [ $DESKTOP_SESSION != ubuntu ]; then
	exit 0
fi

while true; do
sleep $DELAY

SHOW_LAUNCHER=$(wmctrl -lpG | grep -v "Hud\|Dash" | grep -c "$SHOW_X $SHOW_Y") 
HIDE_LAUNCHER=$(wmctrl -lpG | grep -v "Hud\|Dash" | grep -c "$HIDE_X $HIDE_Y") 

if [ $SHOW_LAUNCHER -eq 0 -a $HIDE_LAUNCHER -eq 0 ]
then
	CURRENT=$(gconftool-2 --get "/apps/compiz-1/plugins/unityshell/screen0/options/launcher_hide_mode")
	if [ $CURRENT -ne 0 ]
	then
		gconftool-2 --type int --set "/apps/compiz-1/plugins/unityshell/screen0/options/launcher_hide_mode" 0
	fi
else
	CURRENT=$(gconftool-2 --get "/apps/compiz-1/plugins/unityshell/screen0/options/launcher_hide_mode")
	if [ $CURRENT -ne 1 ]
	then
		gconftool-2 --type int --set "/apps/compiz-1/plugins/unityshell/screen0/options/launcher_hide_mode" 1
	fi
fi
done

For the uninitiated, how does one actually apply this script? Do you just open terminal and cut and paste, or something else?

Any help would be much appreciated.

Cheers.

Firstly install wmctrl (Search in the software centre)
and create a folder in your home directory called scripts.

Put the launcher into never hide mode with this terminal command...

Code:

gconftool-2 --type int --set "/apps/compiz-1/plugins/unityshell/screen0/options/launcher_hide_mode" 0

Then maximize firefox and get your maximized xy values by entering in the terminal...

Code:

wmctrl -lpG

eg

Code:

glen@Oneiric:~$ wmctrl -lpG
0x01600004  0 1935   0    0    1680 1050 Oneiric Desktop

These are your x y values for a maximized window with the launcher showing.

Now hide the launcher with...

Code:

gconftool-2 --type int --set "/apps/compiz-1/plugins/unityshell/screen0/options/launcher_hide_mode" 1

Enter (Hint: pressing the up arrow when in the terminal will cycle through previous commands)

Code:

wmctrl -lpG

and you will get your x y values when the launcher is hidden.
eg

Code:

glen@Oneiric:~$ wmctrl -lpG
0x01600004  0 1935   0    0    1680 1050 Oneiric Desktop

These are your x y values for a maximized window with the launcher hidden.

Open gedit and copy and paste in the script.
Edit the script to reflect your values.
eg this is the section of the script I edited for my resolution and username.

Code:

# Change settings
DELAY="2" # Set delay

SHOW_X="1630" # Use wmctrl -lpG and find max X Y values when launcher is in never hide mode
SHOW_Y="1026" 

HIDE_X="1680" # Use wmctrl -lpG and find max X Y values when launcher is in autohide mode
HIDE_Y="1026"

SCRIPT_PATH="/home/glen/scripts/launcher.sh" # Change path

Change to your user name and add the scripts foder, then save as
launcher.sh in the scripts folder in your home directory.
You can save anywhere,really, just make sure "SCRIPT_PATH=" points to where you saved it.

Right click on the launcher.sh file
Properties > permissions and mark execute.

To test, left click on launcher.sh and choose "run in terminal".
Unmaximize all windows and then maximize one.

If it works and is what you want add it to start up applications
by browsing to where you saved the script.

Thanks for that... Do I have to use firefox, or will chrome do instead? I don't have FF installed.

Cheers.

Any window will do.I just tried to use any easily identifiable one.

I noticed how hard it is to set up the script and thought if i can do something about that!

Code:

#!/bin/bash
# Install wmctrl before using: sudo apt-get install wmctrl

# User settings
sleep 8 # Time it takes before script starts with autodetection

DELAY="2" # Set delay

# End of user settings

ps -ef | grep "$0" | grep -v "grep\|$$\|/bin/sh" | awk '!/awk/ {print $2}' | xargs -r kill

if [ "$DESKTOP_SESSION" != "ubuntu" ]; then
    exit 0
fi

MAX_W="$(wmctrl -lG | awk '{if ($5 > max) { max = $5;}} END {print max}')"
MAX_H="$(wmctrl -lG | awk '{if ($6 > max) { max = $6;}} END {print max}')"

HIDE_Y="$(expr $MAX_H - 24)"

SHOW_X="$(expr $MAX_W - $(gconftool-2 --get "/apps/compiz-1/plugins/unityshell/screen0/options/icon_size") - 17)"
SHOW_Y="$(expr $MAX_H - 24)"

while true; do
sleep $DELAY

SHOW_LAUNCHER="$(wmctrl -lpG | grep -v "Hud\|Dash" | grep -c "$SHOW_X $SHOW_Y")" 
HIDE_LAUNCHER="$(wmctrl -lpG | grep -v "Hud\|Dash" | grep -c "$MAX_W $HIDE_Y")"

if [ "$SHOW_LAUNCHER" -eq "0" -a "$HIDE_LAUNCHER" -eq "0" ]
then
    CURRENT="$(gconftool-2 --get "/apps/compiz-1/plugins/unityshell/screen0/options/launcher_hide_mode")"
    if [ "$CURRENT" -ne "0" ]
    then
        gconftool-2 --type int --set "/apps/compiz-1/plugins/unityshell/screen0/options/launcher_hide_mode" 0
    fi
else
    CURRENT="$(gconftool-2 --get "/apps/compiz-1/plugins/unityshell/screen0/options/launcher_hide_mode")"
    if [ "$CURRENT" -ne "1" ]
    then
        gconftool-2 --type int --set "/apps/compiz-1/plugins/unityshell/screen0/options/launcher_hide_mode" 1
    fi
fi
done

Only two setting are left and the script should work on most of the computers. If script does not work then probably 2 things happened:

1.) Scripts starts autodetection before session is loaded. Increase the sleep time.
2.) Something changed in Unity or another theme is used with different dimensions. Use manual setup or change the script.

Installation:
-Create empty file and copy/paste the code into it. Save the file and make it executable.
-Create entry in Startup Applications and in command filed point to the script as stinkeye suggested on the picture.

Log out/ Log in and it should work. If Launcher size gets changed Log out/ Log in again and it should work again. I could probably make autodetection if launcher is changed in real-time but i think it's better if less operation gets executed in every interval!

Worked for me, thanks guys!!

EDIT: Well it almost worked. Worked fine when logging out/in, but on re-boot it holds the launcher at auto-hide. The script appears to override any changes you make to Ubuntu Tweak, so you can't change to never hide whilst this script is enabled. So close, but no cigar. Almost there...

Worked fine when logging out/in, but on re-boot it holds the launcher at auto-hide.

There should not be any difference between log out/ log in and reboot. Try to increase sleep time from 8 to 16 maybe it tries to autodetect settings before session is loaded or if u have fast PC you have to wait few seconds after login for the script to start to work.

The script appears to override any changes you make to Ubuntu Tweak, so you can't change to never hide whilst this script is enabled.

True, when the script is running you only get one mode: hide launcher when at least one window is maximized. If u want any other mode you have to close the script first (System Monitor).

**EgoGratis** · March 14th, 2012

Race condition is not something user should think about. This should be done automatically and i added detection when autoconfiguration should start. You will not have problems any more with reboots and you don't have to set sleep time based on how fast sessions loads and if sessions loads fast there is no waiting anymore for the script to start working. There is only one setting left now and it does not need to be changed for the script to work.

For what I see, SHOW_Y and HIDE_Y are the same values (maybe one can be omitted). I also don't know if using "- 24", "- 17" and "+ 17" is the best way. What about these lines after MAX_W and MAX_H?

LAUNCHER="$(wmctrl -lG | grep launcher | awk '{print $5}')"
PANEL="$(wmctrl -lG | grep panel | awk '{print $6}')"

SHOW_X="$(expr $MAX_W - $LAUNCHER)"
SHOW_Y="$(expr $MAX_H - $PANEL)"
HIDE_Y="$(expr $MAX_H - $PANEL)"
