WPF窗体属性在WPF项目里，窗体是必不可少的，他作为一个载体，他的属性也是十分重要的。下面就列举一些WPF的窗体属性。一、窗体的外观 WPF中默认窗口框架的外观，主要取决于Icon、Title、WindowsStyle、ResizeMode等属性。 1、Icon指定窗口的图标；　　 2、Title指定窗口的标题；　　 3、WindowStyle指定窗口样式，有4个取值： ... 阅读详情

是这样的
我有个主窗体
窗体运行起来没什么毛病但是有个很烦躁的地方
我点窗体第一下没反应
比如我点窗体最大化点一下没反应
第二下窗体才最大化了

此窗体加载的一个usercontrol里的按钮也是这样

用窗体的this.Focus()方法没什么作用
不知道有什么办法能解决的。。。

WPF获取焦点时不要虚线框 WPF获取焦点时不需要虚线框我们在写WPF程序的时候回遇到这样的问题，当程序运行的时候，如果获得了焦点，那么在截图的时候控件上会有一个虚线框，对于强迫症患者来说这是个很致命的问题，在找了很多资料之后我终于解决了这个问题。核心代码如下： /// <summary> /// 隐藏控件获得焦点时的虚线框 /// </summary> ... 阅读详情

你用窗体的PreviewMouseDown事件看看，你的第一次操作是否传入了

好吧 ..我是小白
我觉得窗体玻璃化那里没有问题
那你在这里，我其实看不懂，因为我没用过鼠标拖动窗体，但是我想或许和鼠标有关系



 [DllImport("user32.dll", EntryPoint = "SendMessage")]// 移动

        public static extern int SendMessage(int hWnd, int wMsg, int wParam, int lParam);

        [DllImport("user32.dll", EntryPoint = "ReleaseCapture")]

        public static extern int ReleaseCapture();

也就是你的鼠标进来的时候先要和这个有关系，然后再执行其他的，或许这里就是原因。
你在调用这两个函数的时候先注释一下看看
如果是这个问题，修改下代码我能说的就这点

做了个win7的玻璃效果要出问题的话估计是那里
其他地方应该不会有什么问题
