Drawing revision creation handler​

This example demonstrates how the

onDrawingNewRevision
callback sends a request to the host application to store a new drawing revision along with its updated layouts. Once the request completes, the result is returned to the widget through the

onResponse
callback.
TypeScript
Drawing revision creation handler
onDrawingNewRevision: (
    drawing: DIQ_DrawingRevision,
    previousLayouts: Array<DIQ_Layout>,
    newLayouts: Array<DIQ_Layout>,
    onResponse: (result: DIQ_Result) => void
) => {
    fetch("/api/drawings/revision", {
        method: "POST",
        headers: {
            "Content-Type": "application/json"
        },
        body: JSON.stringify({
            drawing,
            previousLayouts,
            newLayouts
        })
    })
        .then(() => {
            onResponse({ success: true });
        })
        .catch((error) => {
            onResponse({ success: false, error });
        });
