Interface ProgressBarSettings

An event to take the value from, instead of setting it by hand: each time the event fires, its first argument becomes the value. The bar stops listening when it is destroyed.

the colour of the border drawn around the bar; null for none

the border's thickness, in pixels, drawn inside the bar's edge

which edge the fill grows from; see ProgressBarDirection

The colour of the fill. A Color is read again every frame, so changing the one you passed changes the bar.

the label's CSS font family

the label's text height, in pixels; 70% of the bar's height (at least 8), rounded, if not given

the bar's full height, in pixels

the label's colour

What the label says, given the value and its 0..1 fraction. The default shows a rounded percentage, such as "75%".

the value that shows as full; given below min, the two are swapped

the value that shows as empty

Called each time the value changes, with the new value, the same as a 0..1 fraction of the way from min to max, and the bar. Not called when the value is set to what it already is.

the gap between the track's edge and the fill on each side, in pixels

the corner radius, in pixels; 0 is square. The fill's corners are reduced by padding, so they stay parallel to the track's.

how far the shadow's soft edge spreads, in pixels; 0 is a sharp edge

The colour of a drop shadow under the bar; null for none. Its alpha sets how dark the shadow is, e.g. "#00000066".

how far right the shadow falls, in pixels; negative goes left

how far down the shadow falls, in pixels; negative goes up

draw a text label centred over the bar

the colour behind the fill; null leaves it hollow, showing whatever is behind the bar

the starting value, clamped between min and max; min if not given

the bar's full width, in pixels
