C#控件开发3—文本显示、文本设值

1.文本设置

1）定义属性

属性：字体、标签、值、单位

 public TextSet(){InitializeComponent();this.txt_Value.ReadOnly = true;}#region 属性  字体、标签、值、单位private Font textFont = new Font("微软雅黑", 12);[Browsable(true)][Category("布局_G")][Description("字体格式")]public Font TextFont{get { return textFont; }set{if (value != null){textFont = value;this.lbl_Title.Font = this.lbl_Unit.Font = this.txt_Value.Font = textFont;}}}private Color textColor = Color.Black;[Browsable(true)][Category("布局_G")][Description("文本颜色")]public Color TextColor{get { return textColor; }set{textColor = value;this.lbl_Title.ForeColor = this.lbl_Unit.ForeColor = this.txt_Value.ForeColor = textColor;}}private float textScale = 0.37f;[Browsable(true)][Category("布局_G")][Description("控件刻度")]public float TextScale{get { return textScale; }set{textScale = value;this.tableLayoutPanel1.ColumnStyles[0].Width = (this.Width - textScale * this.Width) * 0.75f;this.tableLayoutPanel1.ColumnStyles[1].Width = textScale * this.Width;this.tableLayoutPanel1.ColumnStyles[2].Width = (this.Width - textScale * this.Width) * 0.25f;}}private string varTitle = "变量名称";[Browsable(true)][Category("布局_G")][Description("变量名称")]public string VarTitle{get { return varTitle; }set{varTitle = value;this.lbl_Title.Text = varTitle;}}private string varValue = "21.50";[Browsable(true)][Category("布局_G")][Description("输入值")]public string VarValue{get { return varValue; }set{varValue = value;this.txt_Value.Text = varValue;}}private string varUnit = "℃";[Browsable(true)][Category("布局_G")][Description("单位")]public string VarUnit{get { return varUnit; }set{varUnit = value;this.lbl_Unit.Text = varUnit;}}#endregion

2）定义事件

键入使能方法、事件

#region  输入使能事件//正在输入标志位
public bool IsSetting { get; set; }private void txt_Value_Enter(object sender, EventArgs e)
{IsSetting = true;this.txt_Value.ReadOnly = false;
}private void txt_Value_Leave(object sender, EventArgs e)
{IsSetting = false;this.txt_Value.ReadOnly = true;
}//添加输入完成事件
public event EventHandler SettingChanged;private void txt_Value_KeyDown(object sender, KeyEventArgs e)
{if (e.KeyCode == Keys.Enter){//技巧：输入完成移动焦点~输入框变灰this.lbl_Title.Focus();//激活触发事件SettingChanged?.Invoke(this, e);}
}#endregion

2.本文显示

1) 定义属性

变量名称、变量值、单位、字体、控件刻度

//指定默认事件（双击控件进入）
[DefaultEvent("TextShowClick")]
public partial class TextShow : UserControl
{public TextShow(){InitializeComponent();}#region Fields 变量名称、变量值、单位、字体、控件刻度//[Browsable(true)]//[Category("布局_G")]//[Description("变量名称")]//public String VarName { get; set; }private Font textFont = new Font("Segoe UI Variable Display", 15, FontStyle.Bold);[Browsable(true)][Category("布局_G")][Description("字体格式")]public Font TextFont{get { return textFont; }set{if (value != null){textFont = value;this.lbl_Value.Font = this.lbl_Unit.Font = textFont;}}}private Color textColor = Color.Blue;[Browsable(true)][Category("布局_G")][Description("文本颜色")]public Color TextColor{get { return textColor; }set{textColor = value;this.lbl_Value.ForeColor = this.lbl_Unit.ForeColor = textColor;}}private string varValue = "1.0E-5";[Browsable(true)][Category("布局_G")][Description("变量值")]public string VarValue{get { return varValue; }set{varValue = value;this.lbl_Value.Text = varValue;}}private string unit = "Pa";[Browsable(true)][Category("布局_G")][Description("单位")]public string Unit{get { return unit; }set{unit = value;this.lbl_Unit.Text = unit;}}private float textScale = 0.6f;[Browsable(true)][Category("布局_G")][Description("控件刻度")]public float TextScale{get { return textScale; }set{textScale = value;this.tableLayoutPanel1.ColumnStyles[0].Width = textScale * this.Width;this.tableLayoutPanel1.ColumnStyles[1].Width = this.Width - textScale * this.Width;}}#endregion

2）定义事件

鼠标双击控件后进入自定义事件

   #region Event 鼠标双击控件后进入自定义事件//创建委托—事件public delegate void BtnClickDelegate(object sender, EventArgs e);[Browsable(true)][Category("操作_G")][Description("文本双击触发事件")]public event BtnClickDelegate TextShowClick;private void Lbl_Value_DoubleClick(object sender, EventArgs e){TextShowClick?.Invoke(this, new EventArgs());}#endregion
