Looking for a calendar display widget, synchable w/google if possible [SOLVED]

[Logansfury]

Hello everyone,

I have a great amount of desktop real estate, so I wanted a HUD calendar. I was hoping for something that could sync with google calendar and display the events I schedule from my android phone and win machines.

I found this page: https://www.linuxuprising.com/2018/11/h ... -your.html

but it appears to be coded in 2018, so I wonder if it still works. Also the DOS look of it depresses me, I was hoping for a more beautiful GUI calendar.

I goggled briefly but couldnt find anything like a list of current conky calendars to scroll thru and choose from. Does such a page exist that anyone knows of, or does anyone know of working calendar displays that sync and have some gui customability? Colors and font control would be great!

Thanks for reading,

Logan

I never have seen such thing in conky with nice graphics... you're stuck with that conky i guess.
Or if you want nice graphics, you need to make a screenshot of the calendar with a browser in headless mode and then present that image in conky. Problem is the login to google calendar.. so you already need a cooky in headless mode or you get a screenshot of the login page. It can be done, but making a script for it takes a while!

Hello again,

Thanks for joining another of my posts for help

I noted the sweet screenshot Bleys shared at the end of my Mizar clock post. The small calendar he has in his conky looks fine. I would be happy with something similar to that, and ecstatic if it could spawn a window with event day/time info.

Would it compromise my system to try to run that google sync conky calendar from several years back? I think it was from 2018-2020 or thereabouts.

[Bleys]

is actually no great effort to expand my calendar. The function to mark days is available, color and/or type of marking is already adjustable. The only thing missing is a text file with all the current appointments. Your scheduler should provide such a file.
But clickable appointments are not possible with Conky/Lua on-board tools.

But clickable appointments are not possible with Conky/Lua on-board tools.

I believe the newest Conky versions have the abillity to gain mouse events inside the window. But it still seems a hell of a job to align every mouseclick/coordinate with all the days..

[Logansfury]

I am working with Bleys calendar and its a great start. The month numbers are actually lined up with the weekday columns, which wasnt the case in the last working calendar I found.

Once again, my Cinnamon is displaying a background around/behind the calendar despite putting the coding that worked to get the Mizar clock background truly transparent.

Here are the two calendar files with my current edits for colors to match my desktop:

Änderungen des Font (Ubuntu Mono) und/oder der Schriftgröße erfordern auch eine Anpassung der Berechnung der Hintergrund Berechnung!
Das sollte man nur machen wenn man weis was man tut...

Screenshot in first Comment
Changing the font (Ubuntu Mono) and font size also requires an adjustment of the background calculation for the current day!
Only change if you know what you are doing!

does anyone see anything in here that would account for the background being visible? https://imgur.com/a/kONFYwe

You need to check your conky config on double settings!
I see 2 own_window_transparent = true, and 2 own_window_argb_visual = true,
What i miss is own_window_argb_value = 0, and own_window_colour = '000000',
And set own_window_transparent = true, to false

[Logansfury]

I'm at the vet with my dog so I will do these edits shortly.

I note a section called window and shadow settings. I certainly don't need shadows if they are contributing to the window visibility. Should I nuke that whole section?

[Koentje]

You could copy these settings part from the clock widget and replace it in this conky..

Thats exactly what I did! I didnt work but it was responsible for those double entries you noted.

I just got Max home from the Vet, Im going to go over the conkyrc now and delete all double entries and add the sections you advised.

I'm afraid this still displays the background >.<

[Logansfury]

Here is a current screenshot showing the two calendars Im working on customizing.

As you can see, the Minimalis, the Mizar clock, and the triple display calendar all have perfect transparency. Im not sure why the cal I got from Bleys is being problematical.

What you can try is to comment the lua settings out. So it only starts the conky window (very small probably) and see if the background is still visibale. If not, the problem is the lua script, if still visible then the problem lies not in the lua script.

Change these

Code: Select all

	lua_load = './cal.lua',
	lua_draw_hook_post = 'main',

into these

Code: Select all

--	lua_load = './cal.lua',
--	lua_draw_hook_post = 'main',
