A level indicator view, suitable for use as a level or peak meter, etc.
Set the warning and critical thresholds. If meter value is above either threshold, -warningColor%20or%20link#-criticalColor will be shown, respectively (by default, yellow and red). If -drawsPeak is true warning color will be displayed based on -peakLevel rather than value.
| val |
A Float. a = LevelIndicator(bounds:Rect(10, 10, 20, 160)).front; a.value = 0.5; a.warning = 0.6; a.critical = 0.9; a.value = 0.7; a.value = 0.9; |
Sets the style of the view.
| val |
An QLevelIndicatorStyle \continuous or \led (see -stepWidth) (
w = Window().front.layout_(
HLayout(
LevelIndicator().style_(\continuous).value_(1/3),
LevelIndicator().style_(\led).value_(2/3),
)
)
)
|
The width of each led light, for \led.
| val |
An positive Integer. (
w = Window().front.layout_(HLayout(
LevelIndicator().style_(\led).value_(0.8).stepWidth_(1),
LevelIndicator().style_(\led).value_(0.8).stepWidth_(3),
LevelIndicator().style_(\led).value_(0.8).stepWidth_(10),
LevelIndicator().style_(\led).value_(0.8).stepWidth_(50),
));
)
|
The number of steps used in \led style.
| val |
An positive Integer. ( a = LevelIndicator(bounds:Rect(10, 10, 80, 400)).front(); a.value = 1; a.style = \led; a.numSteps = 4; ) |
The number of ticks to display in the view's scale.
| number |
An Integer >= 0. (
w = Window(bounds:100@400).front().background_(Color.black);
w.layout_(HLayout(
LevelIndicator()
.numTicks_(16)
.value_(0.75)
))
)
|
The number of ticks in the view's scale which will be large sized.
| number |
An Integer >= 0. (
w = Window(bounds:100@400).front().background_(Color.black);
w.layout_(HLayout(
LevelIndicator()
.numMajorTicks_(16)
.numTicks_(16)
.value_(0.75)
))
)
|
Determines whether the view draws a separate peak display. This can be useful for displaying both peak and RMS values. If drawsPeak is true -warning and -critical will be displayed based on -peakLevel rather than value.
| bool |
A Boolean. By default the peak is not drawn. (
w = Window().front().layout_(HLayout(
LevelIndicator().style_(\continuous).value_(0.75).drawsPeak_(true).peakLevel_(0.9),
LevelIndicator().style_(\led).value_(0.75).drawsPeak_(true).peakLevel_(0.9)
))
)
|
Sets the level of the peak display. (See -drawsPeak.)
| val |
A Float. (
w = Window().front().layout_(HLayout(
LevelIndicator().style_(\continuous).value_(0.1).drawsPeak_(true).peakLevel_(0.3),
LevelIndicator().style_(\continuous).value_(0.1).drawsPeak_(true).peakLevel_(0.5),
LevelIndicator().style_(\continuous).value_(0.1).drawsPeak_(true).peakLevel_(0.7),
LevelIndicator().style_(\continuous).value_(0.1).drawsPeak_(true).peakLevel_(0.9),
))
)
|
Sets the color of the meter, as well as the warning and critical colors.
| color |
A Color. ( l = LevelIndicator(bounds:Rect(100, 100, 100, 400)).front().value_(1).style_(\led); l.meterColor = Color.blue(0.9); l.warningColor = Color.blue(0.7); l.criticalColor = Color.blue(0.5); ) ( // inverse l.background = Color.blue; l.meterColor = Color.black.alpha_(1); l.warningColor = Color.black.alpha_(1); l.criticalColor = Color.black.alpha_(0.3); ) |
