Editor Settings
Diagram settings defines the property defaults for the diagram elements and EditorSettings extendsDiagramSettings to cover options for those settings in the Editor.
Default options
We can change the options for stroke colors for all stencil types by settingeditor.settings.defaultStrokeColorSet property like this:
editor.settings.defaultStrokeColorSet = new ColorSet(
"magenta",
"yellow",
"green"
);Now property editors for all shapes will contain only these three colors for stroke color options.
Contextual options
Like with the diagram settings, we can also specify custom setting options for specific stencil and connector types. Here's how we define a different color set for ellipse stencils:
editor.settings.setContextColorSet(
"EllipseStencil",
"stroke",
new ColorSet("red", "blue", "black")
);Demo
Here are all these settings in action (or access the demo on Codesandbox).
