Changing WPF title bar background color

问题:

I have a WPF Windows application. I need to change the background color of the title bar. How can I do that?

回答1:

In WPF the titlebar is part of the non-client area, which can't be modified through the WPF window class. You need to manipulate the Win32 handles (if I remember correctly).

Here's an example on how to achieve this:

    <Grid DockPanel.Dock="Right"
      HorizontalAlignment="Right">

        <StackPanel Orientation="Horizontal"
                HorizontalAlignment="Right"
                VerticalAlignment="Center">

            <Button x:Name="MinimizeButton"
                KeyboardNavigation.IsTabStop="False"
                Click="MinimizeWindow"
                Style="{StaticResource MinimizeButton}" 
                Template="{StaticResource MinimizeButtonControlTemplate}" />

            <Button x:Name="MaximizeButton"
                KeyboardNavigation.IsTabStop="False"
                Click="MaximizeClick"
                Style="{DynamicResource MaximizeButton}" 
                Template="{DynamicResource MaximizeButtonControlTemplate}" />

            <Button x:Name="CloseButton"
                KeyboardNavigation.IsTabStop="False"
                Command="{Binding ApplicationCommands.Close}"
                Style="{DynamicResource CloseButton}" 
                Template="{DynamicResource CloseButtonControlTemplate}"/>

        </StackPanel>
    </Grid>
</DockPanel>

Handle Click Events in the code-behind.

For MouseDown -

App.Current.MainWindow.DragMove();

For Minimize Button -

App.Current.MainWindow.WindowState = WindowState.Minimized;

For DoubleClick and MaximizeClick

        if (App.Current.MainWindow.WindowState == WindowState.Maximized)
        {
            App.Current.MainWindow.WindowState = WindowState.Normal;
        }
        else if (App.Current.MainWindow.WindowState == WindowState.Normal)
        {
            App.Current.MainWindow.WindowState = WindowState.Maximized;
        }

I hope this helps.

You can also create a borderless window, and make the borders and title bar yourself

Check the following sample WPF customizing the appearance of a window in XAML

This sample shows how to fully customize the style/appearance of a window, including the non-client areas: title bar, borders, max, min and close buttons whilst still providing all the expected functionality.
