我创建了一个SolidColorBrush非GUI线程,并希望将其传递给GUI线程来显示它,但我得到InvalidOperationException:( The calling thread cannot access this object because a different thread owns it.即使我尝试Freeze();它).如何将在线程X中创建的对象传递给线程Y?
我知道我可以SolidColorBrush在GUI线程中创建这个对象Dispatcher,但这会使一切变得复杂......我想在工作线程中创建它.
额外细节:
我在一些静态类中初始化一些静态委托,以允许从业务层向GUI发送消息:
public static class Gui{
private static PrintMethodDelegate _printMethod;
public static void InitializeGuiInterface(PrintMethodDelegate printMethod){
_printMethod = printMethod;
}
public static void Print(GuiMessage data) { _printMethod(data); }
}

初始化(在GUI线程中):

如何使一个元素看起来像是在边框"下方",但是当边框有圆角时,边框的内容"在"上方?
这就是我想要完成的事情:当鼠标移动到边框时,从左上角绘制一个"窗帘",直到它覆盖整个边框的内容或者可能只是它的3/4,就像这个例子:

这个"幕布"旨在携带额外的控件来更新其盒子内容.
我现在卡住了创建红色路径 - 我不能使它沿着黑色边框完美对齐,所以它看起来像是来自边界下方,但高于其内容.

该JsonToken enum中Newtonsoft.Json namespace含有,除其他外,该条目JsonToken.StartConstructor.
我很可能误解了这个令牌的含义,因为我认为JS的构造函数方法在JSON中无效,就像没有function,表达式或var令牌一样.
