玩转控件:重写/重绘Dev中MessageBox弹窗控件

發(fā)布時(shí)間：2023/12/4 编程问答 27 豆豆

生活随笔收集整理的這篇文章主要介紹了玩转控件:重写/重绘Dev中MessageBox弹窗控件小編覺(jué)得挺不錯(cuò)的,現(xiàn)在分享給大家,幫大家做個(gè)參考.

????????很久沒(méi)有更新博客了，本想著直接發(fā)一篇《手撕ERP》系列，從控件重寫(xiě)、重繪，到框架搭建，再到部分模塊實(shí)現(xiàn)+業(yè)務(wù)的。但是每次動(dòng)手的時(shí)候，都覺(jué)得難以下手。直接從數(shù)據(jù)庫(kù)設(shè)計(jì)開(kāi)始吧，模塊設(shè)計(jì)還沒(méi)定下來(lái)，從模塊設(shè)計(jì)開(kāi)始吧，winform自帶控件和DevExpress控件用起來(lái)布局實(shí)在太難看了。算了，從低做起吧。接著6-7年前的玩轉(zhuǎn)控件系列開(kāi)始，工欲善其事必先利其器！利器備好，框架搭建完畢，模塊設(shè)計(jì)就是拖控件而已！

????

????????Talk is Cheap,Show me the Code!

????????首先，項(xiàng)目中新建一個(gè)窗體（用于后面的彈窗載體），按自己意愿做好布局效果，當(dāng)然關(guān)于皮膚方面，大家可以應(yīng)用界內(nèi)很成熟的皮膚控件（具體就不列舉了，避免打廣告的嫌疑），或者后期自己代碼實(shí)現(xiàn)。本篇主要介紹如何重寫(xiě)/重繪控件，磨自己的利器，至于利器上貼個(gè)動(dòng)漫圖片還是其他花里胡哨的圖案，請(qǐng)根據(jù)自己的喜好來(lái)。大概效果如圖（有潔癖的請(qǐng)自己細(xì)心布局）：

????????窗體后臺(tái)代碼分析如下：

????????首先窗體集成DevExpress：

public partial class frm_MessageBox : DevExpress.XtraEditors.XtraForm

????????其余初始化動(dòng)作代碼如下，備注很詳細(xì)就不一一列舉了：

/// <summary> /// 確定按鈕 /// </summary> private SimpleButton btn_OK;/// <summary> /// 取消按鈕 /// </summary> private SimpleButton btn_Cancel;/// <summary> /// 中止按鈕 /// </summary> private SimpleButton btn_Abort;/// <summary> /// 重試按鈕 /// </summary> private SimpleButton btn_Retry;/// <summary> /// 忽略按鈕 /// </summary> private SimpleButton btn_Ignore;/// <summary> /// 是按鈕 /// </summary> private SimpleButton btn_Yes;/// <summary> /// 否按鈕 /// </summary> private SimpleButton btn_No;/// <summary> /// 要在消息框中顯示的文本 /// </summary> private string text;/// <summary> /// 要在消息框的標(biāo)題欄中顯示的文本 /// </summary> private string caption;/// <summary> /// System.Windows.Forms.MessageBoxButtons 值之一，可指定在消息框中顯示哪些按鈕 /// </summary> private MessageBoxButtons buttons;/// <summary> /// System.Windows.Forms.MessageBoxIcon 值之一，它指定在消息框中顯示哪個(gè)圖標(biāo) /// </summary> private MessageBoxIcon icon;/// <summary> /// System.Windows.Forms.MessageBoxDefaultButton 值之一，可指定消息框中的默認(rèn)按鈕。 /// </summary> private MessageBoxDefaultButton defaultButton;/// <summary> /// 消息彈出框參數(shù)實(shí)體 /// </summary> MessageBoxModel _MessageBoxModel = default(MessageBoxModel);

????????界面初始化：

/// <summary> /// 支持修改彈出框的按鈕標(biāo)題描述 /// </summary> /// <param name="pMessageBoxModel"></param> public frm_MessageBox(MessageBoxModel pMessageBoxModel) {InitializeComponent();if (pMessageBoxModel == null)pMessageBoxModel = new MessageBoxModel();this.ControlBox = false;this.text = pMessageBoxModel.MsgText;this.Text = pMessageBoxModel.FormText ?? "Stephen's UserControl";this.caption = pMessageBoxModel.FormText;this.buttons = pMessageBoxModel.MsgButton;this.icon = pMessageBoxModel.MsgIcon;this.defaultButton = pMessageBoxModel.MsgxDefaultButton;this._MessageBoxModel = pMessageBoxModel; }/// <summary> /// 顯示一個(gè)具有指定文本、標(biāo)題、按鈕、圖標(biāo)、默認(rèn)按鈕的消息框 /// </summary> /// <param name="text"></param> /// <param name="caption"></param> /// <param name="buttons"></param> /// <param name="icon"></param> /// <param name="defaultButton"></param> public frm_MessageBox(string text, string caption, MessageBoxButtons buttons, MessageBoxIcon icon, MessageBoxDefaultButton defaultButton) {InitializeComponent();this.ControlBox = false;this.text = text;this.Text = caption ?? "Stephen's UserControl";this.caption = caption;this.buttons = buttons;this.icon = icon;this.defaultButton = defaultButton; }

????????窗體Load事件綁定彈窗按鈕事件：

????????代碼比較簡(jiǎn)單，就是把初始化按鈕事件和把初始化的彈窗中的按鈕添加到布局中的Panel容器里面和一些細(xì)節(jié)調(diào)整，關(guān)于方法sysClass.ssLoadMsgOrDefault目前可以不用在意，是我的通用類(lèi)庫(kù)，主要是用來(lái)實(shí)現(xiàn)國(guó)際化的，后續(xù)會(huì)斷斷續(xù)續(xù)為大家介紹這塊代碼。

????????按鈕綁定事件和鍵盤(pán)響應(yīng)事件代碼如下：

private void PaintIcon(Icon icon, int x, int y){Graphics g = this.CreateGraphics();g.DrawIcon(icon, x, y);}void btn_No_Click(object sender, EventArgs e){this.DialogResult = DialogResult.No;}void btn_Yes_Click(object sender, EventArgs e){this.DialogResult = DialogResult.Yes;}void btn_Ignore_Click(object sender, EventArgs e){this.DialogResult = DialogResult.Ignore;}void btn_Retry_Click(object sender, EventArgs e){this.DialogResult = DialogResult.Retry;}void btn_Abort_Click(object sender, EventArgs e){this.DialogResult = DialogResult.Abort;}void btn_Cancel_Click(object sender, EventArgs e){this.DialogResult = DialogResult.Cancel;}void btn_OK_Click(object sender, EventArgs e){this.DialogResult = DialogResult.OK;}private void frm_MessageBox_KeyUp(object sender, KeyEventArgs e){if (e.Modifiers == Keys.None){if (e.KeyCode == Keys.O && btn_OK != null){btn_OK_Click(null, null);}if (e.KeyCode == Keys.C && btn_Cancel != null){btn_Cancel_Click(null, null);}if (e.KeyCode == Keys.A && btn_Abort != null){btn_Abort_Click(null, null);}if (e.KeyCode == Keys.R && btn_Retry != null){btn_Retry_Click(null, null);}if (e.KeyCode == Keys.I && btn_Ignore != null){btn_Ignore_Click(null, null);}if (e.KeyCode == Keys.Y && btn_Yes != null){btn_Yes_Click(null, null);}if (e.KeyCode == Keys.N && btn_No != null){btn_No_Click(null, null);}}if (e.Modifiers == Keys.Control && e.KeyCode == Keys.C){string mCopyText = "-------------------------------";mCopyText += "\n";mCopyText += lblMsg.Text + "\n";mCopyText += "-------------------------------";Clipboard.SetText(mCopyText);}}private void frm_MessageBox_Paint(object sender, PaintEventArgs e){Icon msgIcon;switch (icon){case MessageBoxIcon.Error:msgIcon = System.Drawing.SystemIcons.Error;break;case MessageBoxIcon.Question:msgIcon = System.Drawing.SystemIcons.Question;break;case MessageBoxIcon.Exclamation:msgIcon = System.Drawing.SystemIcons.Exclamation;break;default:msgIcon = System.Drawing.SystemIcons.Information;break;}e.Graphics.DrawIcon(msgIcon, 40, 20);}}

? ?????????以及彈窗實(shí)體類(lèi)：

/// <summary> /// 彈出框?qū)嶓w /// </summary> public class MessageBoxModel {/// <summary>/// 彈出框標(biāo)題/// </summary>public string FormText { get; set; }/// <summary>/// 彈出框?qū)挾?// </summary>public int FormWidth { get; set; }/// <summary>/// 彈出框高度/// </summary>public int FormHeight { get; set; }/// <summary>/// 彈出框消息內(nèi)容/// </summary>public string MsgText { get; set; }/// <summary>/// 文字大小/// </summary>public int FontSize { get; set; }/// <summary>/// “是”按鈕標(biāo)題/// </summary>public string YesButtonText { get; set; }/// <summary>/// “否”按鈕標(biāo)題/// </summary>public string NoButtonText { get; set; }/// <summary>/// “取消”按鈕標(biāo)題/// </summary>public string CancleButtonText { get; set; }/// <summary>/// 彈出框類(lèi)型（提示型、選擇型等）/// </summary>public MessageBoxButtons MsgButton = MessageBoxButtons.OK;/// <summary>/// 彈出框中顯示的圖標(biāo)/// </summary>public MessageBoxIcon MsgIcon = MessageBoxIcon.Information;/// <summary>/// 彈出框默認(rèn)選中的按鈕/// </summary>public MessageBoxDefaultButton MsgxDefaultButton = MessageBoxDefaultButton.Button1;

????????細(xì)心的讀者會(huì)發(fā)現(xiàn)，博主在實(shí)例彈窗實(shí)體的時(shí)候，有個(gè)語(yǔ)法糖：

/// <summary>/// 消息彈出框參數(shù)實(shí)體/// </summary>MessageBoxModel _MessageBoxModel = default(MessageBoxModel);

????????default(T) 這是C# 7.1的關(guān)鍵字新用法，主要用法是默認(rèn)值表達(dá)式，default對(duì)應(yīng)各種類(lèi)型生成默認(rèn)值列表如下：

類(lèi)型	默認(rèn)值
任何引用類(lèi)型	null
數(shù)值類(lèi)型	0
bool	false
enum	表達(dá)式(E)0生成的值，其中E是枚舉標(biāo)識(shí)符
struct	通過(guò)如下設(shè)置生成的值：將所有值類(lèi)型的字段設(shè)置為其默認(rèn)值，將所有引用類(lèi)型的字段設(shè)置為null?????
可以為null的類(lèi)型	HasValue屬性為false且Value屬性未定義的實(shí)例

羅列一下上述列表中常見(jiàn)類(lèi)型對(duì)應(yīng)的值

default(string) // null default(int) // 0 default(int?) // null default(dynamic) // null default(DateTime) // 0001/01/01 0:00:00 default(DateTime?) // null

????????好了，篇幅有限，具體深入了解請(qǐng)大家自行百度看看微軟文檔的解釋。

?????以上是窗體代碼解析，窗體創(chuàng)建好了，最后一步，創(chuàng)建一個(gè)實(shí)體類(lèi)(暫時(shí)命名KzxMessageBox)用來(lái)調(diào)用彈窗的窗體顯示，具體代碼如下：

if (pMessageBoxModel.FormWidth != 0) frm.Width = pMessageBoxModel.FormWidth;if (pMessageBoxModel.FormHeight != 0) frm.Height = pMessageBoxModel.FormHeight;return frm.ShowDialog();}else{frm.StartPosition = FormStartPosition.CenterParent; if (pMessageBoxModel.FormWidth != 0) frm.Width = pMessageBoxModel.FormWidth;if (pMessageBoxModel.FormHeight != 0) frm.Height = pMessageBoxModel.FormHeight;return frm.ShowDialog(parent);}}} }

????????代碼比較簡(jiǎn)單，創(chuàng)建一個(gè)公共類(lèi)，以及類(lèi)型Messagebox的方法重載而已！

????????最后一步，調(diào)用：

private void button1_Click(object sender, EventArgs e){KzxMessageBox.Show("this is a test!");KzxMessageBox.Show("This is a test!", MessageBoxButtons.OKCancel, MessageBoxIcon.Question, MessageBoxDefaultButton.Button1);}

????????一起看下效果：

????????最后，由于后續(xù)所有重寫(xiě)/重繪控件都在同一個(gè)項(xiàng)目使用，而且Dev系統(tǒng)引用文件較多，壓縮后源碼文件仍然很大，如果有需要源碼的朋友，可以微信公眾號(hào)聯(lián)系博主，源碼可以免費(fèi)贈(zèng)予~！有疑問(wèn)的也可以CALL我一起探討，最最后，如果覺(jué)得本篇博文對(duì)您或者身邊朋友有幫助的，麻煩點(diǎn)個(gè)關(guān)注！贈(zèng)人玫瑰，手留余香，您的支持就是我寫(xiě)作最大的動(dòng)力，感謝您的關(guān)注，期待和您一起探討！再會(huì)！
