C#将【程序集引用-依赖关系】展示到NetronLight图表中

修改NetronLight.SimpleRectangle的Paint事件将文本居中。

		public override void Paint(System.Drawing.Graphics g){g.FillRectangle(shapeBrush,rectangle);if(hovered || isSelected)g.DrawRectangle(new Pen(Color.Red,2F),rectangle);elseg.DrawRectangle(blackPen,rectangle);for(int k=0;k<connectors.Count;k++){connectors[k].Paint(g);}//well, a lot should be said here like//the fact that one should measure the text before drawing it,//resize the width and height if the text if bigger than the rectangle,//alignment can be set and changes the drawing as well...//here we keep it really simple:if (text != string.Empty){//修改文本居中对齐SizeF size = g.MeasureString(text, font, 500, StringFormat.GenericTypographic);float offsetX = rectangle.Width > size.Width ? (rectangle.Width - size.Width) / 2 : 0;float offsetY = rectangle.Height > size.Height ? (rectangle.Height - size.Height) / 2 : 0;g.DrawString(text, font, Brushes.Black, rectangle.X + offsetX, rectangle.Y + offsetY);//g.DrawString(text, font, Brushes.Black, rectangle.X + 10, rectangle.Y + 10);}}

新建窗体FormShowAssemblyDependent

窗体设计器代码如下：

FormShowAssemblyDependent.Designer.cs文件

}
