Restricting The Size

Every WebWindow has a Bounds property of type WindowBounds, which allows you to fine tune the sizing of the window.

You can construct a basic WindowBounds object with a width and height parameter:

Program.cs

// Creates a WindowBounds object with width 640 and height 480
// When the window is displayed, it will be 640x480 pixels
// This will have no minimum or maximum size
var bounds = new WindowBounds(640, 480);

Applying these bounds to the window is simple:

Program.cs

var mainWindow = WebWindow.Create().Show();
mainWindow.Bounds = bounds;

And with method chaining:

Program.cs

var mainWindow =
    WebWindow.Create()
    .WithBounds(bounds)
    .Show();

Minimum & Maximum Size

The WindowBounds object has properties to control the minimum and maximum size of the window:

• MinWidth
• MinHeight
• MaxWidth
• MaxHeight

Using them is trivial:

Program.cs

bounds.MinWidth = 400;
bounds.MinHeight = 400;
bounds.MaxWidth = 1920;
bounds.MaxHeight = 1080;

Or directly from the constructor:

Program.cs

var bounds = new WindowBounds(1280, 720) // 1280x720 represents the initial size
{
    MinWidth = 400,
    MinHeight = 400,
    MaxWidth = 1920,
    MaxHeight = 1080,
};

You can also disable the maximum size entirely, which allows the window to be as big as the user's monitor. This is the recommended approach as some users with high resolution monitors will require large windows.

Program.cs

// Set the maximum size to 0, which will disable it entirely
bounds.MaxWidth = 0;
bounds.MaxHeight = 0;

Locked Window Bounds

You can set the Bounds of a WebWindow to a LockedWindowBounds object as well, which will disable resizing, maximizing, and minimizing.

Program.cs

// The window will be locked to 1280x720
var bounds = new LockedWindowBounds(1280, 720);
mainWindow.Bounds = bounds;
