WPF开发（一）Button 自定义样式、字体大小及界面全屏显示

一、创建样式

新建自定义样式，会出现一个cs和一个配套的xaml文件

二、ButtonEx.cs代码

 public class ButtonEx : Button
    {
        static ButtonEx()
        {
            DefaultStyleKeyProperty.OverrideMetadata(typeof(ButtonEx), new FrameworkPropertyMetadata(typeof(ButtonEx)));
        }


        public ButtonType ButtonType
        {
            get { return (ButtonType)GetValue(ButtonTypeProperty); }
            set { SetValue(ButtonTypeProperty, value); }
        }

        public static readonly DependencyProperty ButtonTypeProperty =
            DependencyProperty.Register("ButtonType", typeof(ButtonType), typeof(ButtonEx), new PropertyMetadata(ButtonType.Normal));


        public ImageSource Icon
        {
            get { return (ImageSource)GetValue(IconProperty); }
            set { SetValue(IconProperty, value); }
        }

        public static readonly DependencyProperty IconProperty =
            DependencyProperty.Register("Icon", typeof(ImageSource), typeof(ButtonEx), new PropertyMetadata(null));


        //ico改变
        public ImageSource ChangeIcon
        {
            get { return (ImageSource)GetValue(ChangeIconProperty); }
            set { SetValue(ChangeIconProperty, value); }
        }
        public static readonly DependencyProperty ChangeIconProperty =
            DependencyProperty.Register("ChangeIcon", typeof(ImageSource), typeof(ButtonEx), new PropertyMetadata(null));


        public CornerRadius CornerRadius
        {
            get { return (CornerRadius)GetValue(CornerRadiusProperty); }
            set { SetValue(CornerRadiusProperty, value); }
        }

        public static readonly DependencyProperty CornerRadiusProperty =
            DependencyProperty.Register("CornerRadius", typeof(CornerRadius), typeof(ButtonEx), new PropertyMetadata(new CornerRadius(0)));


        public Brush MouseOverForeground
        {
            get { return (Brush)GetValue(MouseOverForegroundProperty); }
            set { SetValue(MouseOverForegroundProperty, value); }
        }

        public static readonly DependencyProperty MouseOverForegroundProperty =
            DependencyProperty.Register("MouseOverForeground", typeof(Brush), typeof(ButtonEx), new PropertyMetadata());


        public Brush MousePressedForeground
        {
            get { return (Brush)GetValue(MousePressedForegroundProperty); }
            set { SetValue(MousePressedForegroundProperty, value); }
        }

        public static readonly DependencyProperty MousePressedForegroundProperty =
            DependencyProperty.Register("MousePressedForeground", typeof(Brush), typeof(ButtonEx), new PropertyMetadata());


        public Brush MouseOverBorderbrush
        {
            get { return (Brush)GetValue(MouseOverBorderbrushProperty); }
            set { SetValue(MouseOverBorderbrushProperty, value); }
        }

        public static readonly DependencyProperty MouseOverBorderbrushProperty =
            DependencyProperty.Register("MouseOverBorderbrush", typeof(Brush), typeof(ButtonEx), new PropertyMetadata());


        public Brush MouseOverBackground
        {
            get { return (Brush)GetValue(MouseOverBackgroundProperty); }
            set { SetValue(MouseOverBackgroundProperty, value); }
        }

        public static readonly DependencyProperty MouseOverBackgroundProperty =
            DependencyProperty.Register("MouseOverBackground", typeof(Brush), typeof(ButtonEx), new PropertyMetadata());


        public Brush MousePressedBackground
        {
            get { return (Brush)GetValue(MousePressedBackgroundProperty); }
            set { SetValue(MousePressedBackgroundProperty, value); }
        }

        public static readonly DependencyProperty MousePressedBackgroundProperty =
            DependencyProperty.Register("MousePressedBackground", typeof(Brush), typeof(ButtonEx), new PropertyMetadata());
    }

    public enum ButtonType
    {
        Normal,
        Icon,
        ChangeIcon,
        Text,
        IconText,
        ChangeIconText
    }

三、XAML代码

                                </StackPanel>
                            </Border>
                            <ControlTemplate.Triggers>
                                <Trigger Property="IsMouseOver" Value="True">
                                    <Setter Property="Foreground" Value="{Binding MouseOverForeground,RelativeSource={RelativeSource TemplatedParent}}" TargetName="Txt"/>
                                    <Setter TargetName="Img" Property="Source" Value="{Binding ChangeIcon,RelativeSource={RelativeSource TemplatedParent}}"/>
                                </Trigger>
                                <Trigger Property="IsPressed" Value="True">
                                    <Setter Property="Foreground" Value="{Binding MousePressedForeground,RelativeSource={RelativeSource TemplatedParent}}" TargetName="Txt"/>
                                    <Setter TargetName="Img" Property="Source" Value="{Binding ChangeIcon,RelativeSource={RelativeSource TemplatedParent}}"/>
                                </Trigger>
                            </ControlTemplate.Triggers>
                        </ControlTemplate>
                    </Setter.Value>
                </Setter>
            </Trigger>
        </Style.Triggers>
    </Style>
</ResourceDictionary>

三、前端调用

<local:ButtonEx Grid.Column="0"  Content="城市列表" Icon="/image/定位.png" ChangeIcon="/image/定位蓝.png" ButtonType="ChangeIconText" />

四、界面启动是自动获取字体大小

将函数加入MainWindow()中

        private void FontSizeChange()
        {
            double titlesize = ((SystemParameters.PrimaryScreenWidth / 12) / 3 * 2) / 5;
            System.Windows.Application.Current.Resources.Remove("TitleFontSize");
            System.Windows.Application.Current.Resources.Add("TitleFontSize", titlesize);
            double tabsize = ((SystemParameters.PrimaryScreenWidth / 12) / 3 * 2) / 5 * 0.9;
            System.Windows.Application.Current.Resources.Remove("TabFontSize");
            System.Windows.Application.Current.Resources.Add("TabFontSize", tabsize);
            double gridsize = ((SystemParameters.PrimaryScreenWidth / 12) / 3 * 2) / 5 * 0.8;
            System.Windows.Application.Current.Resources.Remove("GridFontSize");
            System.Windows.Application.Current.Resources.Add("GridFontSize", gridsize);
            double controlsize = ((SystemParameters.PrimaryScreenWidth / 12) / 3 * 2) / 5 * 0.6;
            System.Windows.Application.Current.Resources.Remove("ControlFontSize");
            System.Windows.Application.Current.Resources.Add("ControlFontSize", controlsize);
        }

四、界面启动全屏显示

前端代码
在xaml中的window下添加ResizeMode=“NoResize”

ResizeMode="NoResize"

后端代码

			double x = SystemParameters.WorkArea.Width;//得到屏幕工作区域宽度
            double y = SystemParameters.WorkArea.Height;//得到屏幕工作区域高度
            double x1 = SystemParameters.PrimaryScreenWidth;//得到屏幕整体宽度
            double y1 = SystemParameters.PrimaryScreenHeight;//得到屏幕整体高度
            this.Width = x;//设置窗体宽度 
            this.Height = y;//设置窗体高度
            this.Top = 0;
            this.Left = 0;
