So I've been learning the ctypes library when I came to an unexpected result.

I have following code just to test that ctypes works properly:

I’m using Xubuntu 18.04.2 LTS with the base Greybird theme. My file manager is Nemo (3.8.6) and the window decoration manager is xfwm4.

Thanks to this bash script1 (code below and source here https://forum.ubuntu-fr.org/viewtopic.php?pid=22123363#p22123363), I can display a simple sinusoid on the console window. This animation also adapts automatically upon resizing the window:

[script1]

Using bash, I have been trying to add and display a simple spinner animation in the window decoration xfwm4 (next to the title of the window) of the Nemo (3.8.6) file manager. I’m using Xubuntu 18.04.2 LTS with the base Greybird theme.

Here is what I have tried. I installed the script found at this address:

Works perfectly. This is what I obtained:

On this screenshot, I would like to display the spinner next to the clock. I then tried to incorporate a simple spinner to the above script. I used this:

I'm new in linux, and i know that this should be a stupid question, but i didn't find anything over the internet, so i decide to ask it here:

During the configuration of the COTson program using this line of code it gives me an error:

CODE: ./configure --simnow_dir ../simnow-linux64-4.6.2pub

ERROR :

My apps needs to know when it's window is moved (I need to know the exact position of my app's window relative to the screen (root window / absolute position) - e.g. the one returned by xcb_translate_coordinates with dst_window set to the root window of a screen).

The problem is that I need to receive an event if my window is moved by user. I've added the XCB_EVENT_MASK_STRUCTURE_NOTIFY to the event mask as suggested here on SO, my app only get the event when it's relative position to the window manager's frame is changed (which in turns, the X server doesn't fire any event to my app if the window is moved by user, because it doesn't change the relative position to the window manager's frame). For additional info, here is the window creation code:
