QTPlasmac - 'QImage' object has no attribute 'pixelColor' was created by Uthayne
I am in the process of updating and making the switch over to QTPlasmac. I just cloned the most current version of master to work with. I ran the install script (~/linuxcnc-dev4/lib/python/qtvcp/designer/install_script) to make sure all dependencies were met. Python version the install script detected is version 2.

I set the rip-environment script and then I start the appropriate .ini file after converting using the qtplasmac converter tool, I get the following error:
Traceback (most recent call last):
  File "/home/bryan/linuxcnc-dev4/bin/qtvcp", line 415, in <module>
    APP = QTVCP()

    pColor = self.image.pixelColor(x, y)
AttributeError: 'QImage' object has no attribute 'pixelColor'

Looking at the qtplasmac_handler.py file and commenting out the following lines, I can get qtplasmac to run and everything seems functional. I have only testing jogging and various buttons, but they all seem to be working.
def color_button_image(self, button, color):
        image_path = '{}{}.png'.format(self.IMAGES, button)
        self.image = QImage(image_path)
        for x in range(self.image.width()):
            for y in range(self.image.height()):
                #pColor = self.image.pixelColor(x, y)
                #if pColor.alpha() > 0:
                    newColor = QColor(color)
                #    newColor.setAlpha(pColor.alpha())
                #    self.image.setPixelColor(x, y, newColor)
        self.w['{}'.format(button)].setIcon(QIcon(QPixmap.fromImage(self.image)))

LinuxCNC Version : 2.9.0~pre0

Checking which qtvcp is running and it is in the correct linuxcnc-dev folder (current master)

Commenting those out affects the GUI jog images.

I am guessing it's a pathing issue, as you are using "linuxcnc-dev4" and somewhere it's probably hard coded to "linuxcnc-dev". I remember in the past when I tried to call "linuxcnc-dev" something other than that, it gave me issues.

At any rate, Phill will be able to confirm when he hops on here later.

Also, what version does it say in line 1 of the handler file?

Looking back at the install script output, looks like I had a symbolic link fail.
copy python2 plugin module

libpyqt5_py2.so
ln: failed to create symbolic link '/home/bryan/.designer/plugins/python/qtvcp_plugin.py': File exists

I deleted the file that already existed in /.designer/plugins/python/ and ran the installer script again. It successfully made the new link.
I am going to tidy up the dev folders and rebuild it in just linuxcnc-dev and see if that works.

Handler is VERSION = '0.9.53', so a day old :P

Haha I could just tell because the line numbers made no sense/didn’t match to anything.

Hopefully that fixes your problem. It works fine over here and I’m on RIP, so I suspect that’s the issue.

Fresh pull of master, qtplasmac_handler.py is version 0.9.54, but unfortunately I'm getting the same error.

Here is probably a better log dump for what's happening while it's trying to build the ui

Sounds like too old a version of qt. I can't test qtplasmac on my oldest dev computer.
It has qt version 5.5.1

What does this yield in terminal:
dpkg-query -W -f='${Version}\n' qttools5-dev

I also have Qt 5.5.1. Looks like the function pixelColor was added on version Qt 5.6.

@snowgoer540 : 5.5.1-3ubuntu0.1

Might be the issue. I'm on 5.11.3-4 over here. (on MX Linux 19.3).

Even my Mint 19.2 machine had 5.9.5-0ubuntu1.

Not sure how to tell you to update, Chris or Phill will have to help you there.
