实现步骤: 1.在窗体中放一个容器(例如:Panel),并且将容器的Dock属性设置为Fill。窗体中其他控件都放在这个容器中。 2.添加如下代码: #region 控件缩放double formWidth;//窗体原始宽度 double formHeight;//窗体原始高度 double scaleX;//水平缩放比例 double scaleY;//垂直缩放比例 Dictionary<string, string> controlInfo = new Dictionary<string, string>();//控件中心Left,Top,控件Width,控件Height,控件字体Size /// <summary> /// 获取所有原始数据 /// </summary> private void GetAllInitInfo(Control CrlContainer) { if (CrlContainer.Parent == this) { formWidth = Convert.ToDouble(CrlContainer.Width); formHeight = Convert.ToDouble(CrlContainer.Height); } foreach (Control item in CrlContainer.Controls) { if (item.Name.Trim() != "") controlInfo.Add(item.Name, (item.Left + item.Width / 2) + "," + (item.Top + item.Height / 2) + "," + item.Width + "," + item.Height + "," + item.Font.Size); if (item.Controls.Count > 0) GetAllInitInfo(item); } }private void ControlsChangeInit(Control CrlContainer) { scaleX = (Convert.ToDouble(CrlContainer.Width) / formWidth); scaleY = (Convert.ToDouble(CrlContainer.Height) / formHeight); } private void ControlsChange(Control CrlContainer) { double[] pos = new double[5];//pos数组保存当前控件中心Left,Top,控件Width,控件Height,控件字体Size foreach (Control item in CrlContainer.Controls) { if (item.Name.Trim() != "") { if (item.Controls.Count > 0) ControlsChange(item); string[] strs = controlInfo[item.Name].Split(','); for (int j = 0; j < 5; j++) { pos[j] = Convert.ToDouble(strs[j]); } double itemWidth = pos[2] * scaleX; double itemHeight = pos[3] * scaleY; item.Left = Convert.ToInt32(pos[0] * scaleX - itemWidth / 2); item.Top = Convert.ToInt32(pos[1] * scaleY - itemHeight / 2); item.Width = Convert.ToInt32(itemWidth); item.Height = Convert.ToInt32(itemHeight); item.Font = new Font(item.Font.Name, float.Parse((pos[4] * Math.Min(scaleX, scaleY)).ToString())); } } } #endregion 3.在窗体的Load事件中调用GetAllInitInfo方法,代码如下: private void Form_Load(object sender, EventArgs e){ GetAllInitInfo(this.Controls[0]); } 4.在窗体的Resize事件中调用ControlsChangeInit和ControlsChange方法,代码如下: private void Form_Resize(object sender, EventArgs e){ ControlsChangeInit(this.Controls[0]); ControlsChange(this.Controls[0]); } 注:原创,转载请指明出处。 |
