When turning on light mode from dark mode the GoJS buttons don't seem to change

GoJS
1

When the theme is changed into lightmode or darkmode gojs nodes colors do not get changed. Is there a way to resolve this?

2

GoJS has no built-in knowledge of dark mode/light mode, or any other theme. It is up to your application to provide styling changes to your Parts, perhaps via setting some shared model data for binding: GoJS Data Binding -- Northwoods Software

3

Could you elaborate a bit on setting this shared model data for binding?

4

It’s going to be application-specific. When you detect a change in light/dark mode, you could then set the shared model data property and your nodes could have a binding that would update their colors, like in the example I sent.

5

It does change the colors but only after I change to light/dark mode and refresh it

6

Refreshing shouldn’t be necessary if you executed the change(s) within a transaction.

7

how should i go about doing that

8

Simply wrap your model change in a transaction. See the intro page on transactions: GoJS Transactions -- Northwoods Software.

Giving error “Property ‘startTransaction’ does not exist on type ‘typeof UndoManager’”

It’s not a static function.

Normally, calls should be like:

myDiagram.commit(diag => {
    . . .
})

or

myDiagram.model.commit(mdl => {
    . . .
})
