问题 I'm trying to create in C# WPF a DataGrid with dynamic columns binded to an observable collection of dynamic properties types created at runtime. This is my code : View WPF <DataGrid ItemsSource="{Binding MyCollectionVM, Mode=OneWay}" AutoGenerateColumns="True"> </DataGrid> Then in my ViewModel : public class MyStatiClass { public int ID { get; set; } public string Name { get; set; } public string Address { get; set; } } // Main View Model, using MVVMLight library public class MainViewModel :

问题 In my new SwiftUI project I have an AVPlayer for streaming music from url. Now I need to control the current time of playing track and the volume through sliders, here is the part of design: now I can control the player with UserData final class and its @Published vars, like isPlaying : final class UserData: ObservableObject { // ... @Published var player: AVPlayer? = nil @Published var isPlaying: Bool = false //... func playPausePlayer(withSong song: Song, forPlaylist playlist: [Song]?) { //

问题 I want to use some Haskell libraries (e.g. Darcs, Pandoc) from Python, but it seems there’s no direct foreign function interface to Haskell in Python. Is there any way to do that? 回答1: Provided you can get your Python code to call C, you can call Haskell functions that have been exported via the FFI Another approach would be to write a standard IPC interface, in the case of darcs and pandoc just calling them as vanilla executables and parsing their output might be the way to go.

问题 After asking a question here before someone suggested moving it to the XAML, for designer esthetics. Which after reviewing my code I agreed. Since I can change my colors in my color dictionary and not worry about that chunk of code. So what I've done in my user control was to add a trigger/datatrigger? to the border which accepts the background color. <Border.Style> <Style> <Style.Triggers> <DataTrigger Binding="{Binding Type, ElementName=AlertWindow}" Value="Caution"> <Setter Property=
