GladeVCP text string with HAL pin

Hi,

I am working this ATC panel for my project. I was wondering if there is a way to pass a text string from HAL component to GladeVCP or as a second option to use passed HAL pin numeric value as a selector for text string within GladeVCP. I would like to use ATC step no as a selector to show a text string telling what ATC is actually waiting for ie. "if(step == 2 ) Text_box_string="Waiting for arm vertical position" What would be best solution for this?

You may want to use gmoccapy user messages to show the infk text and do the selection of the 'show' hal pi with a hal component like mux

Hi,

Thank you for suggestion but this is not what I am looking for. Could this be done with Python in handler.py? I was thinking of case structure like:

switch(step_no)

case 1:
message.label.text = "Waiting for user input"
case 2:
message.label.text = "Waiting for shotpin out"

.......
case 31:
message.label.text = "Waiting for enable to go out"

My skills with Python are total 0 so I would need an example that I could modify to suit my needs.

Hallo Tero,

yes, that can be done.
Just make a "user_tab" with a label, embed that one on a position of your choice and set the text with python.
But I do not have a sample for that. You could look on the python file sim/gmoccapy/gmoccapy_plasma/plasma.py.
That one creates hal pin and does handle also widgets to show internal values.

OK, here it is:

#!/usr/bin/env python
# -*- coding:UTF-8 -*-

import hal
import hal_glib
import gtk

step_strings = {
'0': 'home magazine',
'1': 'waiting at start jog is enabled',
'2': 'Request next tool from magazine',
'3': 'Wait for magazine',

'26': 'Check Orient off & magazine shotpin out',
'27': 'Check magazine shotpin out & rotate magazine',
'28': 'Wait for magazine',
'29': 'Check magazine shotpin and advance arm',
'30': 'Check arm advance & arm horizontal',

'32': 'Check arm retract & unlock hand',

'34': 'Check arm vertical & reset atc',
'35': 'Wait for enable to go out',
'100': 'Homing',
'101': 'Jog',
'102': 'Jog return'
}

class AtcClass:

def __init__(self, halcomp, builder, useropts):
self.builder = builder
self.halcomp = halcomp
self.lbl_status = self.builder.get_object("status_label")
#self.lbl_atc_step = self.builder.get_object("hal_atc_step_no")
#self.lbl_current_tool = self.builder.get_object("hal_current_tool")

def _on_destroy(self, obj, data = None):
self.ini.save_state(self)

def on_hal_current_tool_hal_pin_changed(self, widget, data = None):
print("eee %s" % (widget.get_label()));
text_file = open("last_tool.sav", "w")
text_file.write("Last Tool: %s" % (widget.get_label()))
text_file.close()

def on_hal_atc_step_no_hal_pin_changed(self, widget, data = None):
step_label = step_strings.get(widget.get_label(), "none")
self.lbl_status.set_label(step_label);

def get_handlers(halcomp, builder, useropts):
return[AtcClass(halcomp, builder, useropts)]

Seems to work also has ability to save number of tool on spindle for recovering after power down.
