Tkinter widget

Hi I'm doing a new tkinter app on rpi4 for controlling the mixer process. Where is a good source for basic panel meter widgets (like simple voltmeter/panel meter)? Might be interested in a basic bargraph style as well? Nothing too fancy (even this is a bit extreme) https://encrypted-tbn0.gstatic.com...

Re: need to upgrade python

You're only getting pyc files? Hmm.


You are not paying attention...I said we are only sending the pyc files, not the source.

Re: need to upgrade python

The pyc files sent out need to work with python 3.7.x ..The source code files are not to be sent. I will try the link...is building it something bad (you will have to build it)? Unless I'm overlooking something, It's just entering 7 or 8 commands into the rpi, rather than one command, to do the upgr...

Re: rebuilding meld

botspot:
It worked perfectly, just using the command block you initially specified...no extras were needed.
I am now running meld 3.20.1 on the rpi3 and also rpi4

Re: app position is stuck

FYI---I finally found something that works

To drag a window who's titlebar is hidden, use ALT + left click & DRAG, on the window to be moved...you can then drag it around.
If the titlebar is visible you can just left click on that & drag (no alt needed)

app position is stuck

Using standard desktop, rpi4. When I open one particular app, it opens in a position, where it is almost slid off of the desktop. I can't grab the top of it to move it anywhere. It covers over the berry & the left side task bar. I can grab the bottom or right and resize it, but I need to move it, so...

rebuilding meld

What are the latest commands needed to rebuild & install the latest version of meld onto the rpi4/buster? Seems it is now up to version 20, but they don't give the steps needed.

Looking for tkinter widgets

Where is a good library of or source for importing tkinter widgets?
Such examples as : panel meters, gauges, thermometer, knobs, etc.
Since tkinter is heavily used everywhere, is there a good shared repository?

Why are things not set up properly? It's hard to believe nobody at raspberry pi would notice that it misdirecting to the wrong document. Isn't the website being maintained?

Re: installing latest meld

So you couldn't get it to install? I was wondering if I was doing it wrong..sounds like the program isn't ready to use, or their new install is buggy.

installing latest meld

How do you get the latest version of meld installed on the rpi (what are the proper commands/steps)?
https://meldmerge.org


using apt-get install meld installs a rather old version (3.16) instead of the current 3.20

pip3 seems to fail with a screen load of errors.

Re: Command to check GPIO'S?

Hey guys , thanks for the tip.
By the way, I found a command you may not have heard of (there seem to be many undocumented or hard to find):
gpio readall


The will also show a very informative listing of all the I/Os!

Command to check GPIO'S?

What command(s) can be used right after booting up is completed to check the states /modes of all the GPIO's? I believe it is a linux command, rather than python command (though either is fine). This is an RPI3B Also, I'm investigating GPIO 14...I believe GPIO 1-8 are set as inputs with hi-pullups &...

Thanks, I'm looking for an article rather than just a listing (or a listing that uses RPi.GPIO) ...that shows both sides, the class and then using it...I can't tell where the errors occurs (whether the class is made up wrong (such as where to define the pin names & whether self is needed everywhere)...

Re: using RPi.GPIO with defined classes

I've seen a bunch of those articles with setting up classes, but none on any examples of using GPIO...maybe it is not done that way?
I looked at gpiozero Python library, but it seemed to be a list of commands, and not some real setup tutorial
