大概思路

工具栏的图片包含正常的状态和选中的状态,绘制的时候根据状态取对应位置的图片进行绘制;

事件方法

需要响应几个事件:
选取截图区域结束,显示工具栏;
鼠标在工具栏上移动时,设置按钮的焦点状态;
鼠标在工具栏上按下时,设置按钮的焦点状态;

界面元素

技术分享
我这里使用Label控件显示工具栏;
使用Panel控件显示工具的设置项及调色板;

初始化工具栏

        {
            this.lbl_ToolBox.Size = new Size(Properties.Resources.ToolsBox.Size.Width, 26);//设置大小
            this.lbl_ToolBox.Visible = false;//默认不显示
        }
