slider

问题 I'm writing my bachelor thesis about e2e testing in javascript althought I'm not familiar with testing or javascript. So I have this the range input "slider" from the src <input id="sum_slider" class="input-range js-inv-calc-input-sum-range js-input-range" type="range" name="investmentsum" min="20000" max="150000" value="20000" step="1000" title="Investitionsbetrag" style="background: -webkit-linear-gradient(left, rgb(255, 196, 0) 0%, rgb(255, 196, 0) 0%, rgb(119, 119, 119) 0%) no-repeat;">

问题 In swift I can cast an Int to a Double with Int(doubleVariable). But how can I cast a Binding < Double > to a Binding < Int > ? Then I could pass an @Binding var intVar: Int to a function requiring a Double binding. (The context of this is that I have an Int which I want to pass to a Slider in SwiftUI.) 回答1: I don’t think there’s a way to cast but you can create another Binding based on the first one: import SwiftUI var d = 1.0 // Create a Binding<Double> (for lack of another source) var bd =

问题 In the process of learning SwiftUI , I am having this issue. I have this view with a slider: struct RangeSpanView: View { var minimumValue,maximumValue:Double init(minSlide: UInt64, maxSlide: UInt64) { self.minimumValue = Double(minSlide) self.maximumValue = Double(maxSlide) } @State var sliderValue = 0.0 var body: some View { VStack { HStack { Text("\(Int(minimumValue))") Slider(value: $sliderValue, in: minimumValue...maximumValue) Text("\(Int(maximumValue))") }.padding() Text("\(Int

问题 I have a SwiftUI Form I'm working with, which updates values of an EnvironmentObject. I need to call a function when the value of a Picker changes, but every way I've found is either really messy, or causes other problems. What I'm looking for is a similar way in which the Slider works, but there doesn't seem to be one. Basic code without any solution is here: class ValueHolder : ObservableObject { @Published var sliderValue : Float = 0.5 static let segmentedControlValues : [String] = ["one",

问题 I am using a slider to control the position of a playing MediaElement. I have implemented the ValueChanged event to synchronize the position and the value of slider. So when I am dragging on the Thumb, the position of MediaElement also changes. However, this creates bad user experience. The ideal case should be like, after user finishes sliding, MediaElement jumps to that final position. So I am looking for events/handlers like AfterSliding. I have seen solutions like using

问题 I have a HTML control panel with various buttons and sliders. All of the buttons are operational and when clicked send a post request which my Python app receives and then executes functions. I cannot seem to get the slider controls to work, When I adjust the slider I get the following error: werkzeug.exceptions.BadRequestKeyError: 400 Bad Request: The browser (or proxy) sent a request that this server could not understand. KeyError: 'button' This is promising as at least I can see it trying

问题 I want to fire an event onDragStop rather than onChange using a material ui Slider in my React app (so that the event fires fewer times). However, the documentation indicates that the onDragStop function signature only has the mouseevent: function(event: object) => void . So, the following works with onChange : <Slider onChange={ (e, val) => this.props.update(e, control.id, val) } /> However, this event doesn't have a second parameter val : <Slider onDragStop={ (e, val) => this.props.update(e

问题 I am trying to draw a scatter plot with a point that moves based on a parameter adjusted by a slider. I need the parameter to be the position in a list of the coordinates. I have it so the scatter plot gets drawn and I can manually move the point by change the position, but when I try to implement the slider it is displayed, but can not be drug to update the plot. Any help would be great. What I have so far is below. Thanks. %pylab from mpl_toolkits.mplot3d import Axes3D from matplotlib

问题 As a continuation of this question: Set value to slider directly I have the very same problem updating the circle slider. My problem is that I set the values of the circle with the mouse click and drag, but I cannot set the values directly. I want to set the rotation of the circle to a determined value. The full code I am working with is here: https://webgl2fundamentals.org/webgl/lessons/webgl-2d-rotation.html I tried to create a function that updates the value, calling the updateValue
