That works just fine, Phill...thank you very much! Now to see about getting everything ON the tabs to work correctly! (that's mostly a solved problem, fortunately)

Chris,
I have put some odds and ends together, how/where would you like me to send them?

Cheers, Phill.

If you are a member of the linuxcnc maillist you could email me there or for convenience you could compress them and post them here.

Hi Phill-

Since you so generously provided the modifications to .axisrc that enabled me to switch AXIS tabs via HAL buttons, I have been busy whipping up a very nice GladeVCP panel.

I've just noticed something, though, that has me stumped and I am hoping that you'd be willing to shed just a bit more light on it.

When I open a g-code file, I see the blue progress bar go all the way across the bottom of the screen as well as the correct preview (the backplot)...but then I see a floating hourglass and things stay that way indefinitely! Interestingly, everything on my GladeVCP panel seems to still work. Through a fairly laborious process of commenting out one thing at a time, I have determined that the code added to .axisrc is somehow directly related to this behavior.

If, when you have a spare moment you could take a look at my .axisrc (and hopefully suggest a modification) I would be extremely grateful.

Thanks again,
Patrick

ps - had a bunch of difficulty trying to add .axisrc, or even axisrc (it seems as though you MUST include an acceptable extension....!) Didn't want you to think I actually called it axisrc.h ;-)

Here is the relevant part of my .ini file, which might be helpful. (But as I mentioned before, I tried running AXIS without any of these tabs etc. and still had the problem, so perhaps it isn't so necessary.)

[DISPLAY]
DISPLAY = axis

# add GladeVCP panels...
GLADEVCP = -d -u pkf.py geometry_test.glade

EMBED_TAB_NAME = Probe
EMBED_TAB_COMMAND = halcmd loadusr -Wn ppp gladevcp -c ppp -x {XID} -u probe.py pkf_probe2.glade

EMBED_TAB_NAME = Toolchanger
EMBED_TAB_COMMAND = halcmd loadusr -Wn ttt gladevcp -c ttt -x {XID} toolchange.glade

EMBED_TAB_NAME = Camera
EMBED_TAB_COMMAND = halcmd loadusr -Wn ccc gladevcp -c ccc -x {XID} camera.glade

EMBED_TAB_NAME = File Open
EMBED_TAB_COMMAND = halcmd loadusr -Wn fff gladevcp -c fff -x {XID} -u file.py file.glade

EMBED_TAB_NAME = Calculator
EMBED_TAB_COMMAND = halcmd loadusr -Wn rrr gladevcp -c rrr -x {XID}  calculator.glade

I created a seven button GladeVCP panel and ran it with an Axis sim but could not find a problem.
Could you post your complete config.

Cheers, Phill.

Hi-

Thanks very much for taking a look. I'll try to get the whole config put together tonight, but if I don't quite get to it (I have a bunch of somewhat (!) more important "real" work to attend to) I will put it up tomorrow.

regards,
Patrick

I forgot to ask, does this problem occur with every gcode file or one specific file.

Hi again Phill-

The problem occurs with any g-code file. And I've narrowed the problem down (possibly!) to the number of TAB entries in the .axisrc file. I've zipped the whole config with a 'working' and a 'not working' version of .axisrc.

I've tried many combinations of 'if happy' entries. It seems as though things are OK with two (either the non-user preview and DRO tabs OR any two user tabs). Adding a third entry (either one user tab along with preview + DRO -or- three user tabs) seems to trigger the problem. Hopefully that's a clue that will mean more to you than it does to me!!!!

Let's hope that you can re-create the problem, anyway.

Thanks again,
Patrick

This seems to be caused by using Popen as a workaround to read HAL pins for LinuxCNC 2.7.
I guess it is some sort of timing issue.
If we scan four or less buttons per cycle time we can get it to work consistently.
Note that you have a couple less buttons than tabs.

The following workaround for the workaround seems to behave (for 2.7):

Warning: Spoiler!

# for switching tabs via HAL buttons in GladeVCP panel
from subprocess import Popen, PIPE
scanNumber = 0
def user_live_update():
    global scanNumber
    try:
        happy = hal.component_exists('gladevcp')
        if happy:
            if scanNumber == 0:
                if Popen('halcmd getp gladevcp.backplot',stdout=PIPE,shell=True).communicate()[0].strip() == 'TRUE':
                    root_window.tk.call('.pane.top.right','raise','preview')
                # there is no gladevcp button for this...
                #if Popen('halcmd getp gladevcp.dro',stdout=PIPE,shell=True).communicate()[0].strip() == 'TRUE':
                #    root_window.tk.call('.pane.top.right','raise','numbers')
                if Popen('halcmd getp gladevcp.probe',stdout=PIPE,shell=True).communicate()[0].strip() == 'TRUE':
                    root_window.tk.call('.pane.top.right','raise','user_0')
                if Popen('halcmd getp gladevcp.toolchange',stdout=PIPE,shell=True).communicate()[0].strip() == 'TRUE':
                    root_window.tk.call('.pane.top.right','raise','user_1')
                scanNumber = 1
            else:
                # there is no gladevcp button for this...
                #if Popen('halcmd getp gladevcp.camera',stdout=PIPE,shell=True).communicate()[0].strip() == 'TRUE':
                #   root_window.tk.call('.pane.top.right','raise','user_2')
                if Popen('halcmd getp gladevcp.file',stdout=PIPE,shell=True).communicate()[0].strip() == 'TRUE':
                    root_window.tk.call('.pane.top.right','raise','user_3')
                if Popen('halcmd getp gladevcp.calculator',stdout=PIPE,shell=True).communicate()[0].strip() == 'TRUE':
                    root_window.tk.call('.pane.top.right','raise','user_4')
                scanNumber = 0
    except Exception:
        traceback.print_exc()

# remove "do you really want to exit?"
root_window.tk.call("wm","protocol",".","WM_DELETE_WINDOW","destroy .")

# start fullscreen

root_window.tk.call("wm","geometry",".","1920x1000")

# root_window.attributes("-fullscreen",1)

LinuxCNC Master branch does not exhibit this problem using the hal module to read pins.
The following code seems to work ok (for master branch):
