Actually there is a much easier way to do this as GladeVCP has a built in module for saving panel state on shutdown:
www.linuxcnc.org/docs/html/gui/gladevcp....on_gladevcp_shutdown
To try this you need to:
1. Delete 'gladevcp-handler.py' in your 'python' folder (since you seem to have more than one panel it makes more sense to name the handler file like the panel it serves)
2. Save this as 'testpanel-handler.py':
2. Update the tab command In the [DISPLAY] section of your ini to this:
3. Open 'testpanel.ui' in glade and select the 'hal_spinbutton1' widget
a) Remove the handler from 'GtkSpinButton.value-changed' signal (that is the one we added last time):
b) Add 'on_destroy' as handler for the 'GtkWidget.destroy' signal :
That should be all.
Note:
- The 'on_destroy' handler only needs to be added to a single widget in the panel, does not matter which one as they all get destroyed when the GUI is closed.
- This will save/restore the state of the whole panel
- The data is stored in a file named 'testpanel-handler.ini'
- If you have more than one custom panel you can copy this handler file for each of them and replace 'testpanel' in the filename and the 'EMBED_TAB_COMMAND' with the name of the panel.

#!/usr/bin/env python3
import hal
from gladevcp.persistence import IniFile,widget_defaults,set_debug,select_widgets
debug = 0
class HandlerClass:
def on_destroy(self,obj,data=None):
# note: save_state(<object to fetch attributes from>) only:
self.ini.save_state(self)
def __init__(self, halcomp,builder,useropts):
self.halcomp = halcomp
self.builder = builder
self.ini_filename = __name__ + '.ini'
self.defaults = { IniFile.vars: dict(),
IniFile.widgets : widget_defaults(select_widgets(self.builder.get_objects(), hal_only=False,output_only = True))
}
# note extra self.builder parameter
self.ini = IniFile(self.ini_filename,self.defaults,self.builder)
# note - only the object which gets attributes set is passed:
self.ini.restore_state(self)
def get_handlers(halcomp,builder,useropts):
global debug
for cmd in useropts:
exec(cmd, globals())
# get some detail what save/restore etc are doing
set_debug(debug)
return [HandlerClass(halcomp,builder,useropts)]2. Update the tab command In the [DISPLAY] section of your ini to this:
EMBED_TAB_COMMAND= halcmd loadusr -Wn testpanel gladevcp -c testpanel -u python/testpanel-handler.py -H ./gladevcp/testpanel.hal -x {XID} ./gladevcp/testpanel.ui3. Open 'testpanel.ui' in glade and select the 'hal_spinbutton1' widget
