画外壳

画指示灯

VisualStateManager设置运行状态

添加依赖属性

public bool IsRunning
{get { return (bool)GetValue(IsRunningProperty); }set { SetValue(IsRunningProperty, value); }
}// Using a DependencyProperty as the backing store for IsRunning.  This enables animation, styling, binding, etc...
public static readonly DependencyProperty IsRunningProperty =DependencyProperty.Register("IsRunning", typeof(bool), typeof(CoolingTower), new PropertyMetadata(default(bool),new PropertyChangedCallback(OnRunStateChanged))); private static void OnRunStateChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
{bool state = (bool)e.NewValue;VisualStateManager.GoToState(d as CoolingTower, state ? "RunState" : "StopState", false);
}public bool IsFault
{get { return (bool)GetValue(IsFaultProperty); }set { SetValue(IsFaultProperty, value); }
}// Using a DependencyProperty as the backing store for IsRunning.  This enables animation, styling, binding, etc...
public static readonly DependencyProperty IsFaultProperty =DependencyProperty.Register("IsFault", typeof(bool), typeof(CoolingTower), new PropertyMetadata(default(bool), new PropertyChangedCallback(OnFaultStateChanged)));private static void OnFaultStateChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
{bool state = (bool)e.NewValue;VisualStateManager.GoToState(d as CoolingTower, state ? "FaultState" : "NormalState", false);
}

自定义流动管道控件

窗口布局

自定义依赖属性

public int Direction
{get { return (int)GetValue(DirectionProperty); }set { SetValue(DirectionProperty, value); }
}// Using a DependencyProperty as the backing store for Direction.  This enables animation, styling, binding, etc...
public static readonly DependencyProperty DirectionProperty =DependencyProperty.Register("Direction", typeof(int), typeof(Pipeline), new PropertyMetadata(default(int),new PropertyChangedCallback(OnDirectionChanged)));/// 

/// 设置状态
/// 
/// 
/// 
/// 
private static void OnDirectionChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
{int value = int.Parse(e.NewValue.ToString()!);VisualStateManager.GoToState(d as Pipeline, value == 1 ? "WEFlowState" : "EEFlowState",false);
}/// 

/// 设置液体颜色
/// 
public Brush LiquidColor
{get { return (Brush)GetValue(LiquidColorProperty); }set { SetValue(LiquidColorProperty, value); }
}// Using a DependencyProperty as the backing store for LiquidColor.  This enables animation, styling, binding, etc...
public static readonly DependencyProperty LiquidColorProperty =DependencyProperty.Register("LiquidColor", typeof(Brush), typeof(Pipeline), new PropertyMetadata(Brushes.Red));public int CapRadius
{get { return (int)GetValue(CapRadiusProperty); }set { SetValue(CapRadiusProperty, value); }
}// Using a DependencyProperty as the backing store for CapRadius.  This enables animation, styling, binding, etc...
public static readonly DependencyProperty CapRadiusProperty =DependencyProperty.Register("CapRadius", typeof(int), typeof(Pipeline), new PropertyMetadata(0));
