qtvismach, a axis toolpath

I see the basic problem.
The original vismach updates every 100ms but only if something changes.
Qtvcp updates every 100 ms no matter what.

I'm looking into what library options there are to correct this.
In the mean time, you can increase the buffer in qt_vismach.py
look for:
self.plotlen = 16000

Or just pull again - I got it fixed.

I have the following code in the hadler vismach file. (a bit more in the file)

STATUS.connect('graphics-gcode-properties',lambda w, d: update_gcode_properties(d))

def update_gcode_properties(props):
    if props != None:
        print ("update update_gcode")
        property_names = {
                'x': "X bounds:",'x_zero_rxy':'X @ Zero Rotation:',
                'y': "Y bounds:",'y_zero_rxy':'Y @ Zero Rotation:',
                'z': "Z bounds:",'z_zero_rxy':'Z @ Zero Rotation:',
                'a': "A bounds:", 'b': "B bounds:",
            }


Based on graphics-gcode-properties I draw a block of processed material.

This code works, but only when I run it as a built-in qtdragon panel. I want to run the panel as a standalone window.
Currently, to make everything work for me, I run the panel twice, as a standalone window and as a built-in panel. I want to get rid of the built-in panel and run it only as a standalone window.

How do I modify the handler file so that it works as a standalone window?

It seems to me that "STATUS.connect" does not work in standalone vismach

This is a limitation of python/linuxcnc.
The properties signal is produced in the qt_graphics widget.
The receiving widget must be in the same python instance as the qt_graphics widget.
A stand alone panel is a different instance of python then the main screen.

You could add a qt_graphics widget to your stand alone panel.
Or possibly could try using ZMQ messages with a customized handlerfile.

I did it a bit differently.

I wish I had thought of that earlier.

I added this function to the custom handler qtdragon file in the machine directory and now it works.

Returning to the topic of Vismach navigation, there are several issues that make navigating the Vismach window less than pleasant.
When panning the scene left, right, or up and down, the zoom level isn't taken into account, and at greater zoom levels, it's difficult to move the object.

When zooming in, near maximum zoom, there's a very unpleasant effect: many mouse wheel rotations and little zoom effect.

Panning the scene is done with the middle mouse button, while the left mouse button rotates on two axes. This is difficult to master because in the qtdragon preview window, panning is done with the left mouse button. It would be nice to have the same solution in Vismach.

I have a file, qt_vismach.py, that fixes all these issues.
The question is, do you see the problem and the need to improve these things?
