GladeVCP widget customization.................

well, getting my qtdragon going....  joint velocity and following error display is cool.

problem with the jog velocity slider.....it's TOOOOO narrow.

I there a way to make the graghic wider?  I've stretched it in qtdesigner, but the slot and little rectangle don't change size. 
That's what I would like to make wider and larger.   Been looking through all the docs in linuxcnc and in QtDesigner/Qt-5.
Can't find a thing...

little help please, if it's possible.... hopefully in the .qss file.
thanks.
 

You should post in the Qtvcp topic - you are not using Gladevcp.

styling the slider:
doc.qt.io/qt-5/stylesheet-examples.html#customizing-qslider

You might check if the maximuimSize horizontal/vertical has been set

cmorley,
thanks. figured it out. took a bit of back-and-forthing, and open and closing in designer.

another question please. what the heck signal connects to the statusLED for 'spindle at speed'? I have spindle.0.at-speed connected (netted) in hal and it works. but the statusLED does not change.....
Do I need to add a connection (net) ????

Do you mean stateLED?
do you have spindle.0.speed-in connected?

cmorley.
thanks.
ok, found it.... gotta connect mydragon-fe.led_at_speed to spindle.0.speed-in
works now..
I run the actual spindle speed through a 'lowpass' comp to smooth it a bit,
then through a 'near' comp to get the actual 'at-speed' signal to go to spindle.0.speed-in
make sense???
Is this also done somehow in dragon???

check out the velocity and following errors.  lower right.   also the wider jog speed slider, and larger at-speed led.....


of these mydragon gui specific hal pins, what else do I need to connect???

If you use the stateLED you don't need to connect an at speed pin - qtvcp calculates it from the requested speed, override and actual speed.

cmorley,well, i may have messed up. I did a system update, and linuxcnc, etc. got updated....now CRASH.  something with my velocity display.  
honestly, was working fine before the update....LIttle help please? 
not sure if I need to revert, or even how to.....


progress i think. 
i'm pretty sure it has to do with what I added to the hal_glib.py file to get the current joint velocities.just can't recall.  
attached new files here.

this is hal_glib.py, .....(full file attached)
you added the following-error, I added the velocity.   recall joint velocities are in the joint dictionary. 
          'following-error': (GObject.SignalFlags.RUN_FIRST , GObject.TYPE_NONE,(GObject.TYPE_PYOBJECT,)),       
           'velocity': (GObject.SignalFlags.RUN_FIRST , GObject.TYPE_NONE,(GObject.TYPE_PYOBJECT,)),       

        # ferror
        self.emit('following-error', self.old)
        # current velocity
        self.emit('velocity', self.old)


this is my handler file.....(full file attached)
        STATUS.connect('following-error', lambda w, data: self.updateFerrorDisplay(data))
        STATUS.connect('velocity', lambda w, data: self.updateVeloDisplay(data))

    def updateFerrorDisplay(self, data):
        self.w.xFerrorLCD.display('{:+7.5f}'.format(data[0]))
        self.w.yFerrorLCD.display('{:+7.5f}'.format(data[1]))
        self.w.zFerrorLCD.display('{:+7.5f}'.format(data[2]))    

    def updateVeloDisplay(self, data):
        self.w.xVeloLCD.display('{:+6.2f}'.format(data[0]))
        self.w.yVeloLCD.display('{:+6.2f}'.format(data[1]))
        self.w.zVeloLCD.display('{:+6.2f}'.format(data[2]))    

AND   what and where is the 'joint dictionary'  and the 'python interface'?  I want to peruse it....
thanks again for your help.

When you updated it over wrote the hal_glib.py file.
You will need to add back your edits.

See docs here:
linuxcnc.org/docs/devel/html/config/python-interface.html

jmorley,
yup. figured that out. doh.

Would you please add a line or so to the hal_glib.py that makes joint velocity easily available. Same as you did with following error? Please.

I must have done that somehow, but cannot get it back, yet. A permanent code fix would be far better, and not as susceptible to brain fade.....

Please?????

Thanks.

Chris.
well, I found a copy of my hal_glib.py on my VM test setup.....
The file is attached.
I have added a comment lines everywhere I modified the stock file: #added by NR
It works, at least in my VM sim.
If it could use cleanup, please advise. I am not a programmer.
And as I requested above, add the the source this, or whatever is more proper, please.

Thanks.

NOTE.......just moved the files to the mill and all is well for the time......
