Gscreen - a GTK / Glade / Python based screen

Yes, modify and perhaps follow your path and create a new screen based on the python support files Chris created for Touchy.

Well now that you asked I've been thinking about a plasma GUI that displays the cut path and width and length as big as the plotting screen allows but no relation to physical position. The reason for this is you jog to the start point and press start and use G92 to set that point to X0 Y0. With Axis your constantly zooming in and out and panning to find your back plot. And other plasma related items...

Just reading emc_interface.py it seems to be the connection file to the control part of linuxcnc... it would be interesting to find out what the minimum frame work was to connect to linuxcnc is.

Another thing I noticed in Touchy is Chris used a dictionary to connect the signals up. I have found that using the Gtk builder connect_signals to be easier and less typing.

Gscreen does both at the moment ( not a dic but connecting explicitly in the program).
The problem I found annoying when using glade to connect signals is if you cut and paste in the editor it didn't copy the signal name.
It is easy to miss and takes a while to figure out why the method is not being called.

I would think adding a zoom feature gremlin that centres on g92 x0 y0 z0 would be possible if I understand you properly.
Though that doesn't fix AXIS....

What do you consider a minimum feature list for a screen is?
Making one specifically for plasma is interesting though I don't know the specifics of what that requires.

I think the bare minimum needed is a menu, a button bar, a MDI tab, a DRO tab, a backplot tab, and a tab with the loaded file in it. and a status tab.

Menu File > Open, Quit
Button bar E-Stop, Power

Just looking at gscreen.py and I see you took a different approach that cradek did with touchy. Is there any reason to use GladeVCP in a GUI?

I was going to do a screen capture but I'm having a bit of a problem with GtkSourceView missing something or other... I don't see where you are importing gtksourceview so it must be some other magic. I did find that adding import gtksourceview2 seemed to solve the problem...

John

are you importing gladevcp ?

I use gladevcp widgets for a gui because that's what there are there for
seriously if the widget does what I want why would I not use it?
Also since the idea is that a user may change the glade file I would not want to limit then to non gladevcp widgets only.
often you can leverage more options out of gladevcp objects by calling their methods in your program.
In Gscreen some widgets I have changed the source code of to help in this matter (particularly gremlin).
When I merge Gscreen into master those options will be available to everyone.

Hi

Some of cnc-club members have have tried gscreen from mentioned here git repository ( git.mah.priv.at/gitweb/emc2-dev.git )
But unfortunately they were unable to launch linuxcnc having this error messages:

What can cause them? Are there any fix?

Thanks in advance

no 100% sure , but in your home directory you should have a .gscreen_preferences hidden file

They have such file with following content:

Ask them to to replace their preference file with this one:

It seems the default color codes are not actually default...

sorry the zip name was hidden...
