VProgress class

A progress indicator that supports determinate and indeterminate display modes.

The mode controls which variant is rendered:

VProgressMode.determinate — a linear bar filled to value (must be 0.0–1.0).
VProgressMode.linearIndeterminate — an animated linear bar for unknown progress; value is ignored.
VProgressMode.circularIndeterminate — an animated circular spinner for unknown progress; value is ignored.

The size parameter applies only to the circular indeterminate mode, allowing selection of small, medium, or large spinner sizes.

Example

// Determinate — 65% complete
VProgress(value: 0.65)

// Linear indeterminate — unknown progress
VProgress(mode: VProgressMode.linearIndeterminate)

// Circular indeterminate
VProgress(mode: VProgressMode.circularIndeterminate, size: VProgressSize.large)
