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:

复制代码
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();
    }
复制代码

 

组件基类的属性:

复制代码
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
    }
复制代码

组件基类的事件:

复制代码
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
}
复制代码

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。
