GScreen and some understanding gap of hal-widgets

Hi Chris,

thank you for your support!

I will remove the save-button. I use gcode editing like an additional mode (like manual, mdi, auto) and when I change edit mode to auto, saving of edit-buffer should happen without additional user interaction.
I already have a togglebutton for the edit-mode, so the saving will move to that method.
... but as buffer transfer between widgets works, I'm sure, I'll get saving to work.
.

I need to find some time to add some samples to the docs...

Sure!

What I would like to know:
- how can I change fontsize of EMC_Sourceview (like label, button or the like)
- how can I create a button with an Icon and no text

cheers Reinhard

A button can have a image added to it by using one of the options on the righthand side of the editor.
Click on an existing button, in the general tab on the right hand side there is an option

image with optional label
under it you will see 'image widget' click the ... box.
a pop up comes up pick new.
This will add an image widget to the widget tree.
click the image widget and in the general tab on the right you will see options to pick images or to set a path name.

in handler add to top:

import pango

in __init__ function add:

font = pango.FontDescription('sans16')
self.widget.edit_GCodes.modify_font(font)

Hi Chris,

that's the most obvious way and I already tried that.
The only thing that happened: glade designer crashed

No matter, whether I create the image from the button by new image or create an image by myself ...
Then I tried to do it without designer and changed the xml manually ...
That way the button displays a placeholder for the icon, but does not show the icon.

The only way that works so far (discovered recently) is a code snippet from gladevcp iconview placed at initialize_widgets in my handler classThat shows a really ugly icon - which I would like to change naturally!

Then I wanted to know, where the icons come from and executed iconview.py

Thank you for the pango hint!

Hi Chris,

thanks a lot for the hint to pango and all of your help and patience!
That was the key to break through

Don't know why, but with designer I was not able to use an image - with or without button ...
From python it works like charming. Very nice.
With pango I was able to use TTF with pixelbased sizes and images on buttons that support transparency ...
I'm very happy with the current state. I could realize every visual requirement.
Now I can dedicate to work behind the scenes - wire signals and the like ...

Here's the current test-state:

Looks pretty darn good -I really like the button icons.
I think I would add a horizontal pane between the gocode display and the graphics, so you could adjust the split between them - sometimes it's nice to see all the gcode without scrolling.

Glad you are having success!

@ Rheinhard nice work simple workable
will you share your files after testing the finished result

sharing my work is no question - if someone is interested in, why not ...
But keep in mind, that what I did til now was just a bit playing around. The real work starts now.

There's stil some research to do and then I have a lot of doing ahead.
I want the ui be manageable without usage of a mouse - so I have to learn about keyboard shortcuts, change handlers and icons of the softkey-buttons, disable buttons based on signals / system state, replace or overlay existing widgets by others (i.e. to enter position where a dro is shown) and much more ...
I wonder why editing gcode is not a machine state in linuxcnc. It is in most comercial controllers. So I don't know, whether i have to patch linuxcnc ...
I want to reach somewhat elegant like Heidenhain - but that's a lot of work.
... and last not least: there's stil a lot of artwork to do

next chunk of artwork finished ...
