4.示例 当用户去除Winform窗体边框自行设置窗体外观时用户就不能使用Windows窗体应用的功能对自定义窗体的大小进行随意改变了。 此时手动改变无边框窗体的大小需要自定义改变窗体大小的方法才能实现通过鼠标拖拽自定义窗体的右边、下边、右下角改变窗体的大小。改变自制窗体的大小时主要用到了Cursor类的Position属性以及窗体的Width、Height、Top和Left属性另外还用到了改变窗体大小的计算方法。
1.Cursor类的Position属性 Cursor类代表用于绘制鼠标指针的图像其Position属性用于获取或设置光标位置。该属性的语法格式如下
public static Point Position {get;set;}
参数说明
属性值代表光标位置的Point(采用屏幕坐标)结构。
2.改变窗体大小的计算方法 重要的算法就是如何根据鼠标的移动来设置窗体的大小首先用当前鼠标在屏幕上的X坐标值减去窗体左边距与屏幕左边距的距离然后再加上鼠标与边框右端的距离并将值设为当前窗体的宽度。实现代码如下
Form.Width Cursor.Position.X-Frm.Left(Pan.Width -Example_X); 其中Form为窗体名称Pan为显示窗体边框的控件名称Example_X为鼠标按下时的X坐标值。说明以上计算方法是在Panel控件的MouseMove事件中执行的。
3.Resources设计
1Resources资源图片管理 2GetObject方法设计 图片资源的属性是自动生成的但是在程序中获取或加载图片的GetObject方法需要手动设计进Resources.Designer.cs中。
internal static Image GetObject(string v)
{return v switch{panel_TitleLeft panel_TitleLeft,panel_TitleMiddle panel_TitleMiddle,panel_TitleRight panel_TitleRight,panel_Left panel_Left,panel_Right panel_Right,panel_BottomLeft panel_BottomLeft,panel_BottomMiddle panel_BottomMiddle,panel_BottomRight panel_BottomRight,pictureBox1_Image pictureBox1_Image,_ null};
}
