我們?cè)陂_發(fā)項(xiàng)目中不使用按鈕,但是在WPF中有很多方法可以定義按鈕的樣式,也可以重寫其模板,接下來,錯(cuò)新技術(shù)頻道小編為大家介紹的是WPF圖片按鈕的實(shí)現(xiàn)方法,一起來了解吧!
直接代碼
public class ImageButton : System.Windows.Controls.Button { /// <summary> /// 圖片 /// </summary> public static readonly DependencyProperty ImageProperty = DependencyProperty.Register("Image", typeof(ImageSource), typeof(ImageButton), new PropertyMetadata(null)); /// <summary> /// 圖片的寬度 /// </summary> public static readonly DependencyProperty ImageWidthProperty = DependencyProperty.Register("ImageWidth", typeof(double), typeof(ImageButton), new PropertyMetadata(double.NaN)); /// <summary> /// 圖片的高度 /// </summary> public static readonly DependencyProperty ImageHeightProperty = DependencyProperty.Register("ImageHeight", typeof(double), typeof(ImageButton), new PropertyMetadata(double.NaN)); /// <summary> /// 構(gòu)造函數(shù) /// </summary> static ImageButton() { DefaultStyleKeyProperty.OverrideMetadata(typeof(ImageButton), new System.Windows.FrameworkPropertyMetadata(typeof(ImageButton))); } /// <summary> /// 設(shè)置圖片 /// </summary> public ImageSource Image { get { return GetValue(ImageProperty) as ImageSource; } set { SetValue(ImageProperty, value); } } /// <summary> /// 圖片寬度(屬性) /// </summary> public double ImageWidth { get { return (double)GetValue(ImageWidthProperty); } set { SetValue(ImageWidthProperty, value); } } /// <summary> /// 圖片高度(屬性) /// </summary> public double ImageHeight { get { return (double)GetValue(ImageHeightProperty); } set { SetValue(ImageHeightProperty, value); } } }樣式代碼
<Style TargetType="{x:Type xi:ImageButton}"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type xi:ImageButton}"> <Grid> <Grid.RowDefinitions> <RowDefinition Height="*"/> <RowDefinition Height="Auto"/> </Grid.RowDefinitions> <Border x:Name="border" Grid.RowSpan="2" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" SnapsToDevicePixels="true" CornerRadius="3,3,3,3"/> <Image Grid.Row="0" Source="{TemplateBinding Image}" Width="{TemplateBinding ImageWidth}" Height="{TemplateBinding ImageHeight}" VerticalAlignment="{TemplateBinding VerticalAlignment}"/> <ContentPresenter Grid.Row="1" HorizontalAlignment="Center" Margin="{TemplateBinding Padding}" VerticalAlignment="Center" RecognizesAccessKey="True" /> </Grid> <ControlTemplate.Triggers> <Trigger Property="IsPressed" Value="True"> <Setter Property="Foreground" Value="#999999"/> </Trigger> </ControlTemplate.Triggers> </ControlTemplate> </Setter.Value> </Setter> </Style>調(diào)用實(shí)例
