Description

a basic TextField that starts small and grows when you type in it. here's the code:

        TextField("", text: $input.value)
            .textFieldStyle(.plain)
            .font(.system(size: inputTextSize))
            .frame(minWidth: inputWidth, alignment: .leading)
            .fixedSize()
            .padding(6)
            .padding(.trailing)
            .onChange(of: input.value) { searchString in
                // TODO: should the trimming be happening here?
                let targets = AppCore.shared.wooshyEngine.search(for: searchString.trimmingCharacters(in: .whitespaces))
                AppCore.shared.wooshyEngine.clean()
                AppCore.shared.wooshyEngine.highlight(elements: targets)
            }
            .overlay(alignment: .trailing) {
                if input.showPreloading {
                    VStack {
                        ProgressView()
                            .padding(.trailing, 6)
                            .padding(.top, inputTextSize > 28 ? 6 : 0)
                            .controlSize(.small)
                        if inputTextSize > 28 {
                            Spacer()
                        }
                    }
                }
            }
