[Emc-users] Numeric entry with touchscreen and Glade
My milling machine has a a touchscreen, and no keyboard. It works nicely with Touchy for normal milling. I am trying to set up a custom tab for the hobbing setup. I have it working, but entering DP and tooth count is a bit painful. I am currently using spinbuttons, but as far as I can see (and as far as google can see) there is no way to make the spinbutton arrows bigger than tiny which is rather awkward on a touchscreen. So, what is the right way to do numeric entry in GladeVCP and a touchscreen? -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto -- ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
Re: [Emc-users] Numeric entry with touchscreen and Glade
There is a numeric-only popup keyboard used with pyngcgui in some sim configs (example: configs/sim/touchy/ngcgui/pyngcgui_touchy.ini) (based on original work by J. Thornton) Example python code to use: #!/usr/bin/env python import popupkeyboard g_popkbd = popupkeyboard.PopupKeyboard(use_coord_buttons=False) if g_popkbd.run(initial_value='',title='your_title'): print result=,g_popkbd.get_result() else: print user canceled -- Dewey Garrett -- ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
Re: [Emc-users] Numeric entry with touchscreen and Glade
Andy As I have it, the size of the spinbox is fixed but if you have a look at how we did it in the plasma screen of gmoccapy it might help. We used a button for positive increment and one for negative. There is s label above the buttons and that label value is changed by pushing either button. Small bit of python is required to run the buttons. On 2014-10-27 14:29, andy pugh wrote: My milling machine has a a touchscreen, and no keyboard. It works nicely with Touchy for normal milling.

Oh well :)
For anyone else interested:
in the gtkrc file I previously posted:
look in that file for:
style spin
{
engine pixmap
{
image
{
function= BOX
recolorable = TRUE
state= PRELIGHT
file= spin2.png
border = { 4,5,4,5 }
stretch = TRUE
}
snip
add to it:
style spin
{
xthickness = 20
ythickness = 20
engine pixmap
snip
It is easy to over do this.
In fact to really do this right it is possible to only change the size of
specific
spinboxes... but it ties you to a theme that was made for it.

[Emc-users] Lathe conversion with Mesa 5i25 / 7i76
I'm back at work on my lathe conversion, reviewing what I have so far, cleaning up documentation, etc. I've run into an issue / question, hopefully I'm just missing something. I have my spindle encoder connected to the Mesa 7i76 TB3 encoder inputs, which seems to be ok (still have to test operation). I'm looking to connect my MPG encoder somewhere on the 7i76, and I though that could be done on regular inputs due to it's relatively low frequency operation. Looking in PNCConf I don't seem to see an option to put the MPG encoder elsewhere. Am I missing something? Is it supported but not in PNCConf?

Re: [Emc-users] Lathe conversion with Mesa 5i25 / 7i76
HAL supports a nearly infinite list of things. Configuration wizards by there very nature can only support a small subset of that. You can certainly load a software encoder counter and use it for the MPG. But if the Mesa card provides enough encoders (one per servo axis, one for the spindle, and one for the MPG), you might as well use a hardware encoder counter even though the speed is low. If you run out of hardware encoders, then use the software counter and a couple of GPIO pins.

I believe you have two options. If the firmware is right, I believe there is a different 5i25/7i76 mode that has an MPG input. That MPG will be specific pins though (check the manual form Mesa) This is a nice option as there is a x1 mode just for MPGs. The other option is to load a software encoder counter and use any GPIO inputs to supply it (even a spare parport) I'm not sure if you would need a base thread or if the servo thread would be fast enough - but I would bet the servo thread is fast enough. Surely others can give you more specific answers. Chris M -- ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users

Then set the ignore flag, call the handler then unset the flag, ready for the next real entry. Hmm. What I didn't mention is that there are 4 boxes in practice (mm and inch CP too) so I was hoping to use the same handler for all of them, and just decide who was the new-one on entry.

So you can check what called the handler. I am not sure what style of handler you are using.. def my_handler(self,widget): if widget == SOME WIDGET REFERENCE and flag: return True again hard to suggest without code in front of me.

If I enter a Mod number I want the DP box to be updated to show the equivalent DP, And vice-versa. Unfortunately this ends up in an infinite loop of calls, as the change to one invokes a callback that changes the other which invokes a callback. ] In VBA you get round this with Application.ProcessEvents = 0 (IIRC). Does anyone know how to do the equivalent thing with Python and Glade. (Using Glade to create the GUI means no chance to grab the event handler ID at event connection time) module.handler_block_by_func(module.on_change) dp.handler_block_by_func(dp.on_change) Looked like it might work, but doesn't. In my UI the DP entry gets processed with the on_dp_entry_activate callback. The Mod gets processed with on_mod_entry_activate. Part of the processing of one entry is to calculate and update the other entry display. Changing the other entry from the calc doesn't cause an activate, so there is no looping. It may be that looking at what event is being used for your entry might shed light on your loop. -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/ -- ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users

Thinking about it, if I end up using a pop-up keypad this might all be moot, the keypad can call the update values code. Unfortunately not, it only tells you who sent the message. but since you know _you_ sent the message (by using the flag) you probably can make it work. Glade signals options using the glade editor is weak. In general I create my signals and handlers programmically because of this. and this particular problem, updating a widget without endless loop seems common but I have not seen a well thought out (by GTK creators) way. PNCconf goes to great lengths to overcome this and I would do it different if I did it again (I'd use flags) Chris M -- ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
