仿QQ面板举一反三之拉幕式窗口

 设计昨天尝试了仿QQ面板的设计(具体请看:http://www.cnblogs.com/KenBlove/archive/2008/09/27/1300938.html ),今天忽然想如果将面板横着放,不就成了一个拉幕式的窗口了么?

说做就做.立即动手:

首先,和QQ面板不同的就是QQ面板设计当点击Module button的时候,会显示下一级的button.但是这次我们做的不同,应该显示不同的内容,道理大同小异.我们将在panel中加入usercontrol,至于usercontrol里面要显示什么内容,就随便你发挥了.

先看看最终界面吧:

点击右边相应button,则可以显示不同的usercontrol,形成初步的拉幕效果:

看完界面,我们来说说具体的实现吧.先在新建一个C# windows Application,拖拉相应的控件(重点是中间有一个panel控件,其余都是装饰),如图:

像做QQ面板一样,我先定义一些必要的变量和属性:

        private string[] _Module;
        private int _ModuleButtonWidth = 25;

        /// <summary>
        /// 初始模块
        /// </summary>
        public string[] Module
        {
            get { return _Module; }
            set { _Module = value; }
        }

定义好变量,我们开始写Form1_Load函数:

        private void Form1_Load(object sender, EventArgs e)
        {
            this.panel1.BorderStyle = BorderStyle.None;
            //初始化
            Module = new string[] { "初始模块1", "初始模块2", "初始模块3", "初始模块4", "初始模块5" };

            for (int i = 0; i < Module.Length; i++)
            {
                //增加模块Button
                Button btn = new Button();
                btn.FlatStyle = FlatStyle.Popup;
                btn.Width = _ModuleButtonWidth;
                btn.Height = this.panel1.Height;
                btn.Name = string.Format("Button{0}", i.ToString());
                btn.Text = Module[i];
                btn.Left = this.panel1.Width - _ModuleButtonWidth * (Module.Length - i);
                btn.Click += new EventHandler(btn_Click);
                this.panel1.Controls.Add(btn);
            }
        }

就是将Button加到Panel中,很简单!下边开始写点击Button加载usercontrol的操作:

        private void btn_Click(object sender, EventArgs e)
        {
            //标志是否找到用户点击的Button
            bool findOutStatus = false;

            //清除上一次操作加载的子菜单项
            for (int i = 0; i < this.panel1.Controls.Count; i++)
            {
                if (this.panel1.Controls[i].GetType().Name == "Panel")
                {
                    this.panel1.Controls.RemoveAt(i);
                }
            }

            for (int i = 0; i < this.panel1.Controls.Count; i++)
            {
                if (this.panel1.Controls[i].GetType().Name == "Button")
                {
                    //重新定义各个button位置
                    if (!findOutStatus)
                    {
                        this.panel1.Controls[i].Left = _ModuleButtonWidth * i;
                    }
                    else
                    {
                        this.panel1.Controls[i].Left = this.panel1.Width - _ModuleButtonWidth * (Module.Length - i);
                    }

                    //找到所点击的Button,在其下加载子项
                    if (this.panel1.Controls[i].Name == ((Button)sender).Name)
                    {
                        findOutStatus = true;

                        Panel panel = new Panel();
                        panel.BackColor = Color.AliceBlue;
                        panel.Left = _ModuleButtonWidth * (i + 1);
                        panel.Width = this.panel1.Width - _ModuleButtonWidth * Module.Length;
                        panel.Height = this.panel1.Height;
                        switch (i)
                        {
                            case 0:
                                panel.Controls.Add(new ucPart1());
                                break;
                            case 1:
                                panel.Controls.Add(new ucPart2());
                                break;
                            case 2:
                                panel.Controls.Add(new ucPart3());
                                break;
                            case 3:
                                panel.Controls.Add(new ucPart4());
                                break;
                            case 4:
                                panel.Controls.Add(new ucPart5());
                                break;
                        }
                        this.panel1.Controls.Add(panel);
                    }
                }
            }
        }

大概意思代码里面都有说了..怎么样?很简单吧?! 附完整源代码:https://files.cnblogs.com/KenBlove/WindowsApplication1.7z
