I’m following the documentation for 1.2.6 here ->
My code looks like this
let finishedButton = new ToolbarButton({
className: 'finishedButton',
label: "I have finished my assignment",
onClick: finishedCallback
});
panel.toolbar.insertItem(0, 'finishedButton', finishedButton);
The linter says that the third argument in panel.toolbar.insertItem
should be a widget and that ToolbarButton is not a widget type, but the documentation example does it this way. What am I doing wrong?
