Following on from #17, sometimes instead of just crashing the magnified circle picker appears and replaces the mouse, but then doesn't go away. The mouse isn't frozen (the circle can still be moved around) but the image within the circle doesn't change and it's impossible to click anything.

I've tried to take a screenshot of this but it doesn't work. The only way to gain control again is to go over to a tty and kill the program from there.

At least, that looks like it might be the problem. This is what happens when I run it at the command line:

$ pick-colour-picker 
ERROR:root:Could not find any typelib for Unity

I'm running Xubuntu 13.10 (I know) and successfully installed pick using the trusty deb file, via the PPA. I'm using XFCE as a desktop env. and don't have unity installed.

i'm on archlinux and i would like to try this application. How to install please ?

Currently the snap version string is hardcoded to master, it would be preferable to determine the snap version dynamically from Git.

Setting the version property to git should pretty much do the job.

AppCenter Dashboard found some issues with your debian/control file. While we will continue
to try to build your project, we recommend you take a look and fix these
problems for next time.

Flickers and does not pick up the colors on my Ubuntu 16.04. Can get it to work by scrolling mouse wheel frantically.

Just reporting this bug, I have no feedback other than it will only let me capture from the app itself (Pick). But even then it only gets the color black.

On Ubuntu 16.04 Unity, when using Gtk themes other than Ambiance/Radiance, I encountered issues with Pick: The window doesn't hide when it's supposed to and Compiz crashes from time to time.
I was able to reproduce this behavior with the High Contrast Theme (which is installed per default) and the Paper Gtk Theme.

Suggested on omgubuntu, and seems like a good idea.

I launch it, but nothing happens.

I'm seeing a whole lot of errors and AVC denied alerts in the attached logs. Take a look near the end of the file:
journalctl.txt
journalctl-pick.txt

I installed it through GNOME Software, as a snap.

Things I've tried:

• Reboot
• sudo snap start pick-colour-picker, which results in: error: snap "pick-colour-picker" has no services, but then every snap I have installed result in this same error when trying to launch them from the terminal. They will, however, launch properly through their application launchers, except Pick.

The app installs fine, but crashes whenever I click the pick icon in the interface. This is the terminal output, but this all happens before the button is clicked - there's no output after that point.

From the demo video, I can see that the app minimizes its window when you start to pick a color (when the magnifying lens appear). Here on my Ubuntu 18.04.2 (GNOME) machine, it does not. Instead, the window goes completely black during this process. It comes back to normal after I've picked a color.

See screenshot. The black box is Pick's window.

See output of journalctl | grep "pick". I think there are some interesting lines in there.
journalctl.txt

Installed from the Snap Store.

This would allow a user to keep the icon pinned and just right-click -> "Pick a color" or something to launch the picker directly (instead of launching the app and then clicking the little icon in the headerbar).

This would also enable launching into the picker mode directly from the app launcher search on elementary OS.

Hi!
I made a snap package for ColourPicker,
The issues I encounter are:

• pip trying to install PyGObject (from setup.py) but it's not available (everything works if I remove it);
• issue #21 (on ubuntu mate 17.04)

The snap (with a fork of the repo for now, so it can copy the icon) is here:
https://github.com/LyzardKing/ColourPicker/blob/snap/snap/snapcraft.yaml

Please insert Categories=GTK;Graphics; into the desktop file:
/usr/share/applications/pick-colour-picker.desktop
(comes from pick-colour-picker_1.5-0201702011054ubuntu14.04.1_all.deb)

Problem:
on Gnome (MATE), Pick locates in the Other gorup instead of the Graphics group.
Thank you

Hi!

I wanted to install Pick and tried the snap version which worked but, as is usually the case with snaps didn't pickup my theme so I installed the python version which I hoped would integrated better with my desktop only to find out it didn't launch. I reinstalled the snap version and now it doesn't launch either and Pick appears twice in my menus. I think the presence of both version causes a problem and prevents the snap version to launch and I'd like to know how to remove the python version after having done a sudo python3 setup.py install.

As far as I can tell, there is only a way to clear all history. I think it would be nice to delete individual history items

The program's UI copy and colour names are not available for translation into other languages.

I've only been using Pick for a few minutes, but I absolutely love it. Huge improvement over gpick. My one gripe is that it only remembers 5 colors at a time, which is really inadequate when trying to create a harmonious color scheme of 8-16 (or more) swatches. I'm sure the stock option is fine for many use cases. Would you consider however making this parameter value configurable by the user?

If not (or in the meantime), would tweaking the max size be as simple as modifying some global variable somewhere, or is it more complicated than that?

After upgrading my system, the color picker freezes the screen when I press "Pick".

I've tried to compile from the source, but I got this error after a successful install:

compile instructions in the README would be nice tho.
Thanks!

It's hard to select things of a single-pixel's width at the level of zoom in the cursor. It appears to be currently x2 zoom, I think x4 (or more) zoom would be more effective.

From an omgubuntu comment:

it created and then installed itself into the "Other" category in my menu so now it's the only program there. :-) Is there a way you could make it install itself into "Graphics"? Xubuntu user here.

because python 2 is going away, and it's the right thing to do.

There's this white text on white background problem when GTK3's global dark theme mode is enabled. It's not just the text problem though: that whitish area looks out of place on dark mode. See:

On Ubuntu 14.04LTS with Numix theme:

I tested the latest Pick from the PPA on both Ubuntu 16.04LTS and 14.04LTS and this issue exists on both.

It seems there needs to be a sane minimum and maximum level of zoom for the scroll-to-zoom.

The line __main__.py#L1014 causes everything to be blurry, even though the preview was upscaled before with GdkPixbuf.InterpType.NEAREST.
Fun fact: this is getting even worse on HiDPI screens, as the cursor is then scaled up again.

The PPA contains no packages for Ubuntu 17.04 Zesty Zaptus.

Elementary apps generally try to get rid of the menu bar in favor of a gear icon with the menu options.

Greetings! The app is excellent. But could you do so that it is minimized to tray. And picker was caused by one-click, no settings window.

Hi, how to install your nice tool in Fedora please?

Pick is an indispensible tool, and it's a pity it's not as usable on newer releases of Ubuntu. Please bring it up to date if you can.

When you open the picker on Mint 18 Cinnamon edition it occasionally becomes unresponsive/freezes and won't update for a few seconds, after which it changes to the currently hovered part of the screen. This seems to happen if you are moving the cursor more rapidly, if you're doing slow, smooth motions it updates just fine.

The main window disappears but the magnifier doesn't appear

Elementary apps are apparently expected to do this, and the window manager doesn't do it for you, so we need to do it.

Fedora 30, all dependencies installed. No warnings or errors in output of sudo python3 setup.py install.

App shows up in gnome's app list correctly. But if I try to open it, nothing ever happens. And it does seem to be running according to

I tried the snap package and that one does run but it seems like there's a unicode or font issue where no text displays. Screenshot: https://imgur.com/PfN85fN and https://imgur.com/Y0V1Hd7

with 1.5-0201606011144ubuntu16.04.1 under Xfce, I have to unminimize the window and hover the mouse over it before the cursor changes as it should.

Yep, that's right. If there's a one-pixel line on a screen scaled by 2 (using GNOME 3.20.4), there's a 50% chance that I can't pick its color at all. I rarely want to pick a single pixel, but it's still an annoying bug...
I guess the final solution would be to disable DPI scaling completely for the picker window/cursor, but I don't have any clue how that would work.

The whole error message is:

Installing python-cairo lets it start, so maybe this should be added as dependency.

The pick snap name is reserved but not registered, as long as it doesn't conflict with other well-known application you should consider claiming it.

$ snapcraft register pick

We always want to ensure that users get the software they expect
for a particular name.

If needed, we will rename snaps to ensure that a particular name
reflects the software most widely expected by our community.

For example, most people would expect ‘thunderbird’ to be published by
Mozilla. They would also expect to be able to get other snaps of
Thunderbird as 'thunderbird-$username'.

Would you say that MOST users will expect 'pick' to come from
you, and be the software you intend to publish there? [y/N]: y
Registering pick.
The name 'pick' is reserved.

If you are the publisher most users expect for 'pick' then please claim the name at 'https://dashboard.snapcraft.io/register-snap/?name=pick'

Otherwise, please register another name.

When I use the mouse wheel to zoom in, it's hard to position the picker over the exact pixel because of the speed of the mouse. I'm wondering if the motion could be slowed down based on how far zoomed-in we are. Or hold down ctrl or shift when moving to slow it down.

When you click the icon to choose a colour, the window is minimized, but nothing happens until you bring the window back into focus.

I think you already know about this bug but I thought that I should report it anyways.

In the color pick mode, the magnifying lens flashes when you move it.

Hi,

Just installed the package through the PPA and when I run pick-colour-picker I got this issue:

Traceback (most recent call last):

I'm probably missing a gtk thing, or python thing but I cannot figure out what exactly.

Right click to Delete single item from color list history will be an good feature.

ideally, worked out automatically at build time without having to go and hard code it.
