Gscreen - a GTK / Glade / Python based screen

gladeVCP has a graph widget.

Actually with some small code changes halscope should be able to be embedded in GTK projects, using the protocol that gladeVCP uses.
but that seems pretty specialized for a machine controller aside from tuning. I would think that loading it stand alone would suffice. Ddid you have a particular idea for it?

GTK does not have gesture support and will only have it in GTK3 when it does, which we currently do not support.

I played with that a while ago

I'd recommend looking into matplotlib, which even integrates with glade
example: matplotlib.org/1.2.0/examples/old_animat...trip_chart_demo.html
this might help too: www.scipy.org/Cookbook/Matplotlib/Animations
realtime updates: this is wx, but you get the idea: eli.thegreenplace.net/2008/08/01/matplotlib-with-wxpython-guis/

a narrow-focused option would be pystripchart, which I didnt like so much

For those who really liked MACH screens ....

I borrowed a screen JPG converted it to a PNG and built a config to show it.
Then placed a graphics plot in the center and a Gcode view in the upper right.
I placed these in the respective places they belonged to in the original screen.

It's a real pain to set up and you can't resize the screen or everything is out of place.
But it shows the power of Gscreen and gladeVCP ...... and Linuxcnc
If anyone happens to build a nice background pic I would consider actually finishing it as a sample.

why would anyone want a panel that looks like that ?

Two questions:
- can you get a pop-up on-screen keyboard if on a touch-screen the user clicks a text-entry field?
- similarly, can you get a pop-up number-keypad when the user switches focus to a number entry field?

These are ofcourse trivial if you have a keyboard attached, but how does one enter (small amounts of) text and numbers through touchscreen?

Gscreen (actually gladVCP) has a pop up calculator that doubles as a entry widget.
If using a mouse you double click the entry widget if using a touch screen (with the cusor hidden) touch it once.

I didn't build a keyboard widget but I beleive Ubuntu 12.04 has a 'ghosted' keyboard for touch screens built in.
I remember seeing this but have never inverstigated it.

Yes that MACH screen is not for me either, It's the reason I won't bother making it fully functional.
It was the concept of widgets over image that I was interested in. I'm not an artists but if someone comes up with a nice design I will atempt to make it fully functional.

I use 'fixed window' on top of the toplevel window.

This is why you can't resize the screen without the widgets being in the wrong place.

To make this easier I might try building a custom wodget that allows one to load an image on it.
Then I,d have to play with the fixed window widget so the image showed thru....

It seems 'onboard' is a on-screen keyboard available in 10.04 possibly event default - I didn't add it but its there.

it is even embeddable into gladeVCP it seems....

I added a DRO widget to master so building DROs on a gladevcp panel or custom Gscreen skin is easier.
