[JWM] How to disable window decorations per application?

[qp0913562]

Hi,

does anyone know if it is possible to disable window decorations per application with JWM?

In Openbox this apparently is possible as like in this example:

http://openbox.org/wiki/Help:Applications

Code: Select all

<application class="Firefox*">
   <maximized>yes</maximized>
   <decor>no</decor>
</application>

This example would make Firefox run maximized and without decorations.

Would this also be possible with JWM?

Hello qp0913562.

The answer is yes. jwm has a file called jwmrc-personal at /root/.jwm .

Further down in it, it has what jwm calls "groups". In the example below,
the title of the window has been disabled for the xclock program.

<Group>
<Name>xclock</Name>
<Option>notitle</Option>
<!-- <Option>noborder</Option> -->
<Option>nolist</Option>
<Option>nopager</Option>
</Group>

Upon launch, the xclock program window will show borders but not
the title.

The options at the bottom mean that this window will not show in the list
of open programs and neither in the window pager in the task bar.

Notice how you enable or disable a feature in the "noborder" line. As it is
in the example, it is disabled.

If you wish to enable "noborder" for the xclock window, remove the
<!-- at the beginning, and the --> at the end. Do the reverse (put these
arrows back at the beginning and end of the line) if you want to disable
any feature.

IHTH.

Hello musher0.

Your example works perfectly with xclock, but I can't make it work for firefox.

I added:

<Name>firefox</Name>
<Option>notitle</Option>
<Option>noborder</Option>
<Option>nolist</Option>
<Option>nopager</Option>


in the <Group> section, but Firefox opens with the usual decorators.

I've made many tries but with no luck

The outout of xwininfo -root -children is:

Firefox is the ESR version 52.9.0

Hello Wyk72.

I would suggest you live with it?! (No mockery intended. Please read on.)

As you can see in your xwininfo list above, there are "many strains" for "one
Firefox", whereas there is only "one strain" for the Xclock.

I have never used this newer Firefox, but as you probably know, browsers nowadays
are mini-OS's in their own right; they offer their own control of decorations. Maybe
Firefox's internal controls are battling it out with jwm's?

I know the old Opera offered it and now Vivaldi: you can right-click on the top menu
line and then tick a box if you want to display the browser's "borders".

So one asks the browser to do what (s)he wants instead of the WM. Same result!

IHTH.

[bigpup]

make Firefox run maximized and without decorations

Look for Firefox add-ons to do this.

Auto Fullscreen
This one works for me.
After installing this add-on.
Firefox starts in full screen.

Here is info on it.
https://addons.mozilla.org/en-US/firefo ... src=search
Get it from Firefox add-ons.

I am aware of the fact that this answer does not give you a recipe, but some interaction may be done with wmctrl: https://linux.die.net/man/1/wmctrl

[Wyk72]

Thanks, musher0, I think I'll "live with it" for the time being.

I thought it was a trivial matter: after a lot of googling around I've found that browsers have become extremely complex beasts, sometimes difficult to tame. The subject of windows decorations came out in a lot of discussions and there are options exactly for it hardcoded into the browser, but different for every version. Honestly it looks rather ... lame to me, but who am I to judge


@bigpup: I've tried the addon, it works as advertised but was not exactly what I was looking for. I was simply trying to get rid of the window border/title to save a little space in the screen of my laptop.

Indeed: this command

wmctrl -r Mozilla -b toggle,fullscreen


toggles fullscreen mode correctly,but it's not exactly what was I was looking for.

I wanted to start Mozilla as Chrome starts: without windowt title/ decorations but not fullscreen i.e.:

In Xenialpup and most newer versions of Puppy.

menu>Desktop>JWMDesk Manager>Window>Geometry>Enable

If you change to these settings you get this.
See image

However you loose the ability of having a titlebar and what it is used for.
Set at one.
There is no space to click on or put anything in the titlebar.

Just found out.
If you move mouse pointer where the titlebar would be and pointer turns into a resize pointer or the mouse point is in just the right place.
You can right click and still get the titilbar menu.

I can't make it work for firefox.

I added:

<Name>firefox</Name>

It's

Code: Select all

<Name>Navigator</Name>

You could also use this code, which is almost identical with your Openbox example of your first post :

Code: Select all

<Class>Firefox</Class>

Large applications usually generate more than one window, e.g a browser window, an info window etc.
All windows of an application share the same "Class" name while each window type can be identified by its "Name" name.
Use the xprop command and look for the WM_CLASS(STRING) parameter.
Example: For the Bookmarks window of Firefox: you would get WM_CLASS(STRING) = "Places", "Firefox"
"Places" would be Name and "Firefox"would be Class

Note that values are case sensitive!

[tallboy]

One little remark to the use of 'Navigator'. It doesn't work for Palemoon, even if xprop describe otherwise

Code: Select all

WM_CLASS(STRING) = "Navigator", "Pale moon"

To make Palemoon open in a particular position on virual desktop 4, I have to use this code:

Code: Select all

wmctrl -s 3
exec /usr/bin/palemoon "$@" &
sleep 3
wmctrl -r "Pale Moon" -e 0,270,84,1200,910

(and again thank you to MochiMoppel for teaching me how to)

In Xenialpup and most newer versions of Puppy.
menu>Desktop>JWMDesk Manager>Window>Geometry>Enable

I also have the same setup in Lucid 5.2.8.7.

Works perfectly here.
Don't forget to restart JWM after editing JWM's configuration file.

[Wyk72]

@MochiMoppel, thanks a million, using the tag

<Name>Navigator</Name>

did the trick, and my Firefox is now ... more beautiful

The <Class> statement did not work, I think I'm writing it wrong: can you please give me a working example?

[rufwoof]

The <Class> statement did not work, I think I'm writing it wrong: can you please give me a working example?

Code: Select all

<Group>
 <Class>Firefox</Class>
 <Option>notitle</Option>
 <Option>noborder</Option>
 <Option>maximisized</Option>
</Group>

See https://joewing.net/projects/jwm/config.shtml

To find the names/class open a terminal and type xprop and press enter, then move the mouse over the target window and left mouse click. One of the values shown in the terminal window will be something like ...

WM_CLASS(STRING) = "Navigator", "Firefox"

The second value is the class, alternatively the above group statements could have used the Name tag instead to equal effect i.e.

Code: Select all

<Group>
 <Name>Navigator</Name>
 <Option>notitle</Option>
 <Option>noborder</Option>
 <Option>maximisized</Option>
</Group>

Usually just restarting jwm is enough for the changes to take effect i.e. run

jwm -restart

in a terminal window. For some changes/configurations however you may have to completely restart X.

[musher0]

Euh... "maximisized" ? I think the word does not exist.

Are you sure it shouldn't be written "maximized" ?

(Just being the benevolent proof-reader, here!)
