WPF Metro Window full screen

问题

I'm currently working on a WPF application and I don't find how to make my application in full screen. I am using MahApps.Metro so my mainwindow's type is Controls.MetroWindow.

I tried this :

<Controls:MetroWindow x:Class="MyProject.MainWindow"
                      xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                      xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                      xmlns:Controls="clr-namespace:MahApps.Metro.Controls;assembly=MahApps.Metro"
                      xmlns:Views="clr-namespace:MyProject.Views"
                      WindowStyle="None"
                      ResizeMode="NoResize"
                      WindowState="Maximized"
                      Title="MyProject">

But it doesn't hide the Windows taskbar. But it works when I use a simple Window. I looked at the MetroWindow source code, it inherits the Window class, so I don't understand why it's not working.

The only way I found to have a full screen window with Metro, is to set the IgnoreTaskbarOnMaximize propery to true and remove the ResizeMode="NoResize" (see code below), run the app and maximize it.

<Controls:MetroWindow x:Class="MyProject.MainWindow"
                      xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                      xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                      xmlns:Controls="clr-namespace:MahApps.Metro.Controls;assembly=MahApps.Metro"
                      xmlns:Views="clr-namespace:MyProject.Views"
                      WindowStyle="None"
                      IgnoreTaskbarOnMaximize="True"
                      Title="MyProject">

But I would like to hide the Minimize and Maximize button.. Have you got any ideas to start a Controls.MetroWindow in full screen ?

回答1:

I can reproduce your issue. You should report it as a bug Here

Simple workaround for now could be:

Keep your xaml the same as you got to:

<Controls:MetroWindow x:Class="MyProject.MainWindow"
                      xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                      xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                      xmlns:Controls="clr-namespace:MahApps.Metro.Controls;assembly=MahApps.Metro"
                      xmlns:Views="clr-namespace:MyProject.Views"
                      WindowStyle="None"
                      IgnoreTaskbarOnMaximize="True"
                      Title="MyProject">

and in the Window's code-behind:

public MainWindow() {
  InitializeComponent();
  Loaded += OnLoaded;
}

private void OnLoaded(object sender, RoutedEventArgs routedEventArgs) {
  WindowState = WindowState.Maximized;
  ResizeMode = ResizeMode.NoResize;
  ShowMaxRestoreButton = false;
  ShowMinButton = false;
  Loaded -= OnLoaded;
}

This will give you the behavior you want. We pretty much set the state(maximized), hide min/max buttons with the Loaded event and only do it once.

with the latest alpha version you have two different ways to get this:

first

<Controls:MetroWindow x:Class="MyProject.MainWindow"
                      xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                      xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                      xmlns:Controls="clr-namespace:MahApps.Metro.Controls;assembly=MahApps.Metro"
                      xmlns:Views="clr-namespace:MyProject.Views"
                      ResizeMode="NoResize"
                      WindowState="Maximized"
                      IgnoreTaskbarOnMaximize="True"
                      Title="MyProject">

second

<Controls:MetroWindow x:Class="MyProject.MainWindow"
                      xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                      xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                      xmlns:Controls="clr-namespace:MahApps.Metro.Controls;assembly=MahApps.Metro"
                      xmlns:Views="clr-namespace:MyProject.Views"
                      UseNoneWindowStyle="True"
                      WindowState="Maximized"
                      Title="MyProject">

with the second solution you have also no titlebar, no min, max, close buttons
