Is There A Command Line Utility

[Meanie]

I think what you're looking for is wmctrl:[div align=\"right\"][a href=\"index.php?act=findpost&pid=156439\"][{POST_SNAPBACK}][/a][/div]

I don't seem to have that command on either my Zaurus or my desktop.  Is this supposed to be a "stock" command?

its in debian. i am going to compile it for pdaXrom...


uploaded to the new packages announcement thread...

now you tell me after i spend hours reading the X and wnck api

I'm not knowledgeable about this stuff so I was waiting for smarter heads to give me this info and pass it along to you.

Hi guys,

GREAT! Thank you Meanie and Antikx for wmctrl... just the tool which was missing!
Now I have written a script which does what I always looked for.
I wanted the application keys to be handled the way they are handled under Sharp/Cacko:
Push it to start the application.
Push it again when the app is running and it brings the window to the foreground.
VERY handy especially for calendar / address book etc!

Here are the relevant parts from my application wrapper script  (call it "xlaunch" and let the application keys launch "xlaunch kopi" instead of just "kopi" etc.
Works great!
(since this is stripped from my huge wrapper script, I am not sure if this works as written here. But it sohuld at least give the idea and some implementation details):

I like these grep-awk-grep-awk pipes :-)
 

Code: [Select]

#!/bin/bash

ALLOWMOREINSTANCES=0

# Extract binary name from parameter:
BINARY=`echo "$1" | awk '{ print $1 }'`
BINARY=`basename "$BINARY"`


# Check if application already runs: (look for binary
# basename in ps x output column 5

ps x | grep -v "$0" | awk '{print $5}' | grep "$BINARY$" > /dev/null
if  [ $? -ne 1 ]; then

  # Program already runs. Bring it to foreground
  # except if "ALLOWMOREINSTANCES" is set to 1 for the app.

  echo $0: $1 is already running.

  if [ $ALLOWMOREINSTANCES -eq 0 ]; then
    BINPID=`ps x | grep -v "$0" | awk '{print $1 " " $5}' | grep "$BINARY$" | awk '{print $1}'`
    echo DEBUG: PID of $BINARY is $BINPID.
    BINWINID=`wmctrl -l -p | awk '{print $1 " " $3}' | grep " $BINPID$"`
    echo DEBUG: BINWINID of $BINARY is $BINWINID
    wmctrl -i -a "$BINWINID"
    exit 0
  fi

fi



#Start application:

echo $0: $1 is starting. Please wait...

$1
ERRCODE=$?
echo "($1)" exited with errorcode "$ERRCODE".
Now, I'd like to maximize all application windows by default after the app is started using the wrapper script.  
Any idea how to do that?

Code: [Select]

wmctrl -i -r $BINWINID -b add,maximized_vert,maximized_horz
would do this (and does this, I have tested it), but the difficult part is to know when the window has been created and just after that do the maximize.
Some applications need a lot of time to generate their main window.
I thought of implementing a while loop with one pass per second which tests if there is already a window for the PID, and if there is, maximize it.
But maybe someone knows a more elegant solution?

Thanks

Okay, I implmented the maximizing too, now, using that while loop I suggested.

This is the new code (replaced the last three lines of above script with the new mechanism):

Code: [Select]

#!/bin/bash

ALLOWMOREINSTANCES=0

# Extract binary name from parameter:
BINARY=`echo "$1" | awk '{ print $1 }'`
BINARY=`basename "$BINARY"`


# Check if application already runs: (look for binary
# basename in ps x output column 5

ps x | grep -v "$0" | awk '{print $5}' | grep "$BINARY$" > /dev/null
if  [ $? -ne 1 ]; then

 # Program already runs. Bring it to foreground
 # except if "ALLOWMOREINSTANCES" is set to 1 for the app.

 echo $0: $1 is already running.

 if [ $ALLOWMOREINSTANCES -eq 0 ]; then
   BINPID=`ps x | grep -v "$0" | awk '{print $1 " " $5}' | grep "$BINARY$" | awk '{print $1}'`
   echo DEBUG: PID of $BINARY is $BINPID.
   BINWINID=`wmctrl -l -p | awk '{print $1 " " $3}' | grep " $BINPID$"`
   echo DEBUG: BINWINID of $BINARY is $BINWINID
   wmctrl -i -a "$BINWINID"
   exit 0
 fi

fi



#Start application:

echo $0: $1 is starting. Please wait...

# NEW CODE FOR MAXIMIZING:

MAXIMIZE=1

$1 &
PROCESSID=$!
WINDOWEXISTS=0
if [ $MAXIMIZE -eq 1 ]; then
  while [ $WINDOWEXISTS = 0 ]; do
    sleep 1
    WINDOWID=`wmctrl -l -p | awk '{print $1 " " $3}' | grep " $PROCESSID$"`
    if [ $? -eq 0 ]; then
      WINDOWEXISTS=1
      wmctrl -i -r $WINDOWID -b add,maximized_vert,maximized_horz
    fi
  done
fi
This works for all programs of which the first appearing window is the program window, i.e. most programs.
However, programs which show a splash screen, e.g Streamtuner, are not maximized, because the algorithm above detects the splash screen as the program window and tries to maximize that one.
Any idea how to work aroud that?

This does sound pretty slick...  and should be a good workaround for windows that don't have a "start maximized" option.

I suppose a somewhat manual way would be to create a file that lists the names of applications that have splash screens and then compare the current window to that list.  Assuming the splash screen maintains the same PID as the app window, you could try grabbing the window location or size and then create a loop that checks for that to change.  Or does the window ID change when the splash screen disappears and the actual app window is created?  Window ID might be cleaner.

Great work so far dan3k! This will be a great addition to pdaXrom.

Most applications have the ability to have the splash screen disabled (option --no-splash or --nosplash or in the preferences).

BUT: There are apps, e.g. dillo, which don't report a PID to wmctrl, so the mechanism won't work for these.
I have implemented a workaround for them, using the window name instead. If we add a manually created list of window name strings to the script, this will handle now really all kinds of windows.
I'll post that fix later here.
Remind me in case I should forget...
Still testing.

Also, just recompiling smplayer latest version with reduced initial window size so the status line is visible on first start...
Whan letting the launcher script maximize smplayer, smplayer is not able to switch to a smaller window for audio playback after start, so I will disable maximize for smplayer and instead let it use the slightly reduced window size.
Also still testing...
