Sungaila.ImmersiveDarkMode.WinForms

Sungaila.ImmersiveDarkMode

Applies a dark theme to the titlebar of Win32 windows. Can also be toggled automatically whenever the system-wide application theme changes.

Works on Windows 11 (Build 22000) and newer.

Getting started

Call WindowExtensions.SetTitlebarTheme() in the constructor of your System.Windows.Forms.Form and override WndProc like this:

public Form1()
{
    InitializeComponent();
    this.SetTitlebarTheme();
}

protected override void WndProc(ref Message m)
{
    base.WndProc(ref m);
    WindowExtensions.CheckAppsThemeChanged(m);
}
