You can get them from STATUS, as long as the preview window is in the same python context.
Meaning you would need to have the vismach window embedded in, or loaded from, qtdragon.
The normal qtvcp embedding should work, getting a separate window is custom work.

then:
STATUS.connect('graphics-gcode-properties', lambda w, d: self.update_gcode_properties(d))
would give you the raw information in the function update_gcode_properties().
You can see how it was done in qtdragon_handler.py, but something like this:

Code:

def update_gcode_properties(self,props):
        print(props.get('x'))
        print(props.get('y'))
        print(props.get('z'))

That's what you suggested, using STATUS.connect.. I can control the position of the A-axis tailstock.

After reloading the next file, the tailstock is positioned in the appropriate place depending on the dimension of the project in the X axis.

Another thing I want is to re-build the dimensions of the workpiece.

Qt_vismach can update the position of an already built object, but I can't do it to re-build a new workpiece.

I tried adding a new class in primitives.py, analogous to HalTranslate, but it doesn't work.

It would also be interesting to be able to change the colors of some elements, depending on the values of different pins.

How to do it?

The color change pin was pretty easy. This shows an example how to have a pin that flips between two preset colors.

Code:

class HALColor(Collection):
    def __init__(self, color1, color2, parts, comp, var):
        self.color1 = color1
        self.color2 = color2
        self.comp = comp
        self.var = var
        Collection.__init__(self, parts)

    def apply(self):
        try:
            if self.comp is None:
                v = hal.get_value(self.var)
            else:
                v = self.comp[self.var]
        except:
            v = 0
        if v : c = self.color1
        else: c = self.color2

        GL.glPushAttrib(GL.GL_LIGHTING_BIT)
        GL.glMaterialfv(GL.GL_FRONT_AND_BACK, GL.GL_AMBIENT_AND_DIFFUSE, c)

    def unapply(self):
        GL.glPopAttrib()

You need to define the pin:

c.newpin("flipcolor", hal.HAL_BIT, hal.HAL_IN)

then instead of using Color use HALColor:

Code:

link7 = HALColor([0.1,0.1,0.1,1], [1,1,0,1], [link7], c, "flipcolor",)

I added the modified fanuc_200f.py file too for clarity.

Great, it works.

It works when I run it as a built-in window in qtdragon.

I also run the simulation in a standalone window, because
in a built-in window, the toolpath is drawn only if the window is active.
In a separate window, the path is always drawn.
When I run it in a separate window, there is a problem with the hal component and adding the pin.
Maybe add the flipcolor pin in the main hal file, or something else?

Uses a HAL U32 pin to set the color. Alpha can be preset:

Code:

class HALColor(Collection):
    def __init__(self, parts, comp, var, alpha=1.0):
        self.comp = comp
        self.var = var
        self.alpha = float(alpha)
        Collection.__init__(self, parts)

    def apply(self):
        try:
            if self.comp is None:
                v = hal.get_value(self.var)
            else:
                v = self.comp[self.var]
        except:
            v = 0
        r = ((v & 0x000000FF) >> 0)/255
        g = ((v & 0x0000FF00) >> 8)/255
        b = ((v & 0x00FF0000) >> 16)/255
        c =[r,g,b,self.alpha]

        GL.glPushAttrib(GL.GL_LIGHTING_BIT)
        GL.glMaterialfv(GL.GL_FRONT_AND_BACK, GL.GL_AMBIENT_AND_DIFFUSE, c)
        GL.glEnable(GL.GL_BLEND)
        GL.glBlendFunc(GL.GL_SRC_ALPHA, GL.GL_ONE_MINUS_SRC_ALPHA)

    def unapply(self):
        GL.glPopAttrib()
        GL.glDisable(GL.GL_BLEND)

c.newpin("color", hal.HAL_U32, hal.HAL_IN)

link7 = HALColor([link7], c, "color",alpha=0.5)

Have a look at how the tool cylinder is created and updated.
