【.Net码农】WPF组件开发之组件的基类

之前在网上看到很多关于组件开发的资料，但真正可以用到框架内的却很少。今天贴出自己做的组件，并适合大部分框架的代码。

组件开发需要先做出组件的基类，然后由其他的各类组件去继承这个基类，下面是组件基类的代码。

组件基类：

public abstract class Component    {        public abstract string Name { get; }        public abstract string Icon { get; }        public abstract string Description { get; }        public abstract ComponentEvent ComponentEvent        {            get;        }        public abstract ComponentProperty ComponentProperty        {            get;        }        public abstract UIElement CreateUIElement();    }

 

组件基类的属性：

public abstract class ComponentProperty : INotifyPropertyChanged    {        private double width;        private double height;        private double left;        private double top;private string name;        [Category("基本")]        [Description("名称")]        public string Name        {            get { return name; }            set            {                if (name == value) return;                name = value;                OnPropertyChanged("Name");            }        }        [Category("大小")]        [Description("宽度")]        public double Width        {            get { return width; }            set            {                if (width == value) return;                width = value;                OnPropertyChanged("Width");            }        }        [Category("大小")]        [Description("高度")]        public double Height        {            get { return height; }            set            {                if (height == value) return;                height = value;                OnPropertyChanged("Height");            }        }        [Category("位置")]        [Description("距左")]        public double Left        {            get { return left; }            set            {                if (left == value) return;                left = value;                OnPropertyChanged("Left");            }        }        [Category("位置")]        [Description("距上")]        public double Top        {            get { return top; }            set            {                if (top == value) return;                top = value;                OnPropertyChanged("Top");            }        }        #region INotifyPropertyChanged Members　　　　　　//属性的监听事件        public event PropertyChangedEventHandler PropertyChanged;        protected void OnPropertyChanged(string propertyName)        {            if (string.IsNullOrEmpty(propertyName)) throw new ArgumentNullException("propertyName");            PropertyChangedEventHandler handler = PropertyChanged;            if (handler != null) handler(this, new PropertyChangedEventArgs(propertyName));        }        #endregion    }

组件基类的事件：

public abstract class ComponentEvent : INotifyPropertyChanged{#region 这个可以去掉private string _Click;public string Click{　　get{return _Click;}　　set{　　　　if(_Click==value)return;　　　　_Click=value;　　　　OnPropertyChanged("Click");　　}}public void OnClick(object sender,RoutedEventArgs e){　　if(Click!=null){　　　　//事件的处理　　}}#endregion#region INotifyPropertyChanged Members//监听事件public event PropertyChangedEventHandler PropertyChanged;protected void OnPropertyChanged(string propertyName){if (string.IsNullOrEmpty(propertyName)) throw new ArgumentNullException("propertyName");PropertyChangedEventHandler handler = PropertyChanged;if (handler != null) handler(this, new PropertyChangedEventArgs(propertyName));}#endregion}

以上是组件的基类，组件基类打包为模板以及组件开发请关注后续章节，加群可优先哦。
