禁用或隐藏标题栏

Question

我正在使用http://wpfmdi.codeplex.com/库来处理我的WPF应用程序中的MDI。

我有一个包含子容器的Canvas，后者又包含许多小窗口。

我想在我的子窗口上禁用标题栏。这可能吗？我没有找到实现此目的的单个属性，特别是因为MdiChild对象的类型为Control而不是Window。

这是我创建MDIChild的代码，其中包含TableWindow类的对象。

            MdiChild child = new MdiChild()
            {
                MaximizeBox = false,
                MinimizeBox = false,
                Resizable = true,
                ShowIcon = false,
                Content = tableWindow.Content as UIElement
            };

            mainContainer.Children.Add(child);

Answer 1

由于其为Control，因此您必须override其默认模板（ControlTemplate）。

在源代码中，您将看到两个包含MdiChild控件样式的xamls - Aero.xaml和Luna.xaml。可以看到源代码here。只需摆脱包含按钮的StackPanel(ButtonsPanel)和Grid(HeaderContent)。

这就是WPF为我们提供的强大功能，您可以自定义任何控件，通过覆盖它ControlTemplate来让它看起来像你想要的那样。

要覆盖模板，您必须在xaml中重新定义它。您需要做的是create a style again in your Window resources, set the template for the control，它将自动覆盖默认控件模板。只需从here复制粘贴整个模板，然后删除我上面提到的StackPanel和Grid。

<Window.Resources>
   <Style TargetType="{x:Type mdi:MdiChild}">
      <Setter Property="Template">
          <Setter.Value>
              <ControlTemplate>
                  <!-- Copy paste entire template here and
                       just remove the StackPanel and Grid -->
              </ControlTemplate>
          </Setter.Value>
      </Setter>
   </Style>
</Window.Resources>

用此替换ControlTemplate以禁用标题栏，但仍然为控件启用拖动操作和可调整大小的操作 -

<ControlTemplate TargetType="{x:Type mdi:MdiChild}">
   <Border Name="BaseBorder" BorderThickness="1" CornerRadius="5,5,0,0"
           Background="{StaticResource BackBorderBackgroundBrush}"
           BorderBrush="{StaticResource BackBorderBrush}">
               <Grid>
                  <Border Name="ContentBorder"
                          Background="{TemplateBinding Background}"
                          BorderBrush="{TemplateBinding BorderBrush}"
                          BorderThickness="{TemplateBinding BorderThickness}">
                         <ContentControl Content="{TemplateBinding Content}" />
                   </Border>
                  <Thumb Name="DragThumb" Height="20" Margin="0,0,40,0"
