Button

Introduction

The Button control providing an event for handling clicks.

Code Example: Adding a Button

The following code adds a button which increments every time it is clicked:

Separate Method

Button button;

void SomeInitializationFunction()
{
    ...
    button = new Button();
    Root.Children.Add(button.Visual);
    button.X = 50;
    button.Y = 50;
    button.Width = 100;
    button.Height = 50;
    button.Text = "Hello MonoGame!";
    int clickCount = 0;
    button.Click += HandleClick
}

void HandleClick(object sender, EventArgs args)
{
    clickCount++;
    button.Text = $"Clicked {clickCount} times";
}

Lambda

var button = new Button();
button.AddToRoot();
button.X = 50;
button.Y = 50;
button.Width = 100;
button.Height = 50;
button.Text = "Hello MonoGame!";
int clickCount = 0;
button.Click += (_, _) =>
{
    clickCount++;
    button.Text = $"Clicked {clickCount} times";
};

Button responding to clicks by incrementing clickCount

Clicking Programmatically

Clicking can be performed programmatically by calling PerformClick. The following example shows how to click a button when the Enter key is pressed:

var keyboard = FormsUtilities.Keyboard;
if(keyboard.KeyPushed(Microsoft.Xna.Framework.Input.Keys.Enter))
{
    button.PerformClick();
}

Optionally you can pass the input device to the PerformClick method:

button.PerformClick(keyboard);
