Question

what I want is either the GUI knows how to deal with that device and display something like a graphical representation of states etc or it doesn t know

altavir · Answer

I ve done widgets for boolean state and toggles as well as drop boxes

bjonnh · Answer

yeah that s the advantage of Vue and Vuetify they all already exist

bjonnh · Answer

it is really easy to integrate most of them are a one liner

bjonnh · Answer

you have a model with a JS object boolean string number and you just attach it to the widget

altavir · Answer

Such widgets exist everywhere But we need to bind it to device not some property Also it must be automatically updated on device state change

bjonnh · Answer

lt v checkbox v model= mybooleanvalue gt

bjonnh · Answer

and your checkbox is reactive to that variable now both ways in that case

bjonnh · Answer

yeah that s why I want that properties abstraction layer

bjonnh · Answer

I have that for properties now but not actions

altavir · Answer

I was using JavaFX property bindings but even in that case there are some complications For example physical states are not updated immediately

altavir · Answer

Tango has the concept of actions I DF controls I ve implemented actions as a change of special properties But it is quite easy to doe standalone actions like `fun action actionName String meta Meta `

bjonnh · Answer

yep for my measurements I have expected and measured

bjonnh · Answer

so every property has two states GUI can work on expected and tell the user that it is what is expected of that property not necessarily the real value

altavir · Answer

I ve hidden internal state and organized synchronization logic to properly update properties on fast change Probably both approaches are valid

bjonnh · Answer

Yeah that s something I was thinking about as well what to do with ultrafast devices

bjonnh · Answer

which also makes channels unusable for these

bjonnh · Answer

you need to make sure something listens

bjonnh · Answer

and if it isn t fast enough it would just hang

altavir · Answer

Fast daq is a different matter and requires different solutions You do not evaluate each incoming value but accumulate them and produce binary Bunches of data As for slow listeners one could use conflated channels or smoothers Done that as well
