The code to switch must be in Button's action, because this way I know that I can quickly switch from the code, even if it is not in button format. How can I do this? Button in ContentView.swift: Button(action: { //What goes here. Tried Settings(), didn't work }) { Text("Settings") }.buttonStyle(PlainButtonStyle()) Settings.swift: import SwiftUI

问题 I need that when I press the button to show me how many times was the button pressed. I use this method, but on console still show me the number 1. Here is code: button_help.setOnMousePressed(new EventHandler<MouseEvent>() { @Override public void handle(MouseEvent event) { int count = 0; count ++; System.out.println(count); } }); 回答1: Your solution doesn´t work as you are reseting the value of variable every time you click button.

问题 I'm trying to make a button print a string when it's pressed and print another when it's released. I know about the command atribute and the bind method, but I would like to know if it's possible to accomplish it only using atributes or if I have to use methods.
