Openbox, limit area for fullscreen windows or hide gtk title bar

Question

I am using Openbox with tint2 panel. I want to run the Midori browser to see only a web page without the gtk title bar of the browser.

For example I run midori with this command:

$ midori -a https://unix.stackexchange.com/

If I set

<decor>no</decor>

in openbox rc.xml, the title bar of Midori is shown anyway. So I am searching a way to not whow the title bar of the gtk application.

A possible solution is to start Midori in fullscreen mode whit this command:

$ midori -a https://unix.stackexchange.com/ -e Fullscreen

but in this case the tint2 panel is covered by the fullscreen window.

There is a way to limit the area for the fullscreen window in Openbox? I tried with margin option in rc.xml, but this doesn't work with fullscreen windows.

To run the Midori browser without its GTK title bar while also preserving the tint2 panel, you can use the wmctrl command line utility.

First, you need to find out the window ID of the Midori window. In a terminal window, run the command wmctrl -l, which will list all the windows currently open. Look for the window with an app name of 'Midori'. Note down the window ID and then run the command wmctrl -i -r <Window_ID> -b remove,fullscreen to exit fullscreen mode.

Now you can start Midori with the command midori -a https://unix.stackexchange.com/ -e Fullscreen --hide-menubar. This will open the Midori window in fullscreen mode, hiding the GTK title bar and preserving the tint2 panel.
