## Detailed Description
该QMessageBox提示类提供通知用户或询问用户问题,并接收应答模式对话框。
一个消息框显示一个主[text](qmessagebox.html#text-prop)要提醒用户的情况下,一[informative text](qmessagebox.html#informativeText-prop)进一步解释警报或询问用户问题,以及一个可选的[detailed text](qmessagebox.html#detailedText-prop)到如果用户请求它提供甚至更多的数据。一个消息框还可以显示[icon](qmessagebox.html#icon-prop)和[standard buttons](qmessagebox.html#standardButtons-prop)用于接受用户的响应。
提供两个API使用QMessageBox提示,该物业为基础的API ,和静态函数。调用的静态功能之一是简单的方法,但它比使用基于属性的API,弹性较差,其结果是不够丰富。使用基于属性的API被推荐。
### The Property-based API
使用该物业的API ,构建QMessageBox提示的实例,设置所需的属性和调用[exec_](qmessagebox.html#exec)( )来显示讯息。最简单的配置是仅设置[message text](qmessagebox.html#text-prop)属性。
```
QMessageBox msgBox;
msgBox.setText("The document has been modified.");
msgBox.exec_();
```
用户必须点击**OK**按钮来关闭消息框。 GUI的其馀部分被阻塞,直到消息框被驳回。
![](https://img.kancloud.cn/ff/da/ffda0a92ab81fe47d29fc7254f5a77a4_301x124.png)
比只是提醒用户事件更好的办法是还询问用户该怎么办才好。存储在这个问题[informative text](qmessagebox.html#informativeText-prop)属性,并设置[standard buttons](qmessagebox.html#standardButtons-prop)属性设置为你想要的设置的用户响应的组按钮。这些按钮由合并指定的值[StandardButtons](qmessagebox.html#StandardButton-enum)使用按位OR运算符。对于按钮的显示顺序是依赖于平台的。例如,在Windows上,**Save**被显示到左侧**Cancel**,而在Mac OS上,顺序是相反的。
纪念你的标准按钮之一,是你的[default button](qmessagebox.html#defaultButton)。
```
QMessageBox msgBox;
msgBox.setText("The document has been modified.");
msgBox.setInformativeText("Do you want to save your changes?");
msgBox.setStandardButtons(QMessageBox.Save | QMessageBox.Discard | QMessageBox.Cancel);
msgBox.setDefaultButton(QMessageBox.Save);
int ret = msgBox.exec_();
```
这是推荐的做法 [Mac OS X Guidelines](http://developer.apple.com/library/mac/documentation/UserExperience/Conceptual/AppleHIGuidelines/Windows/Windows.html#//apple_ref/doc/uid/20000961-BABCAJID)。类似的准则适用于其他平台,但要注意方式的不同[informative text](qmessagebox.html#informativeText-prop)针对不同的平台进行处理。
![](https://img.kancloud.cn/15/8a/158a51ede8abc99ac8bea7bac293e244_314x135.png)
该[exec_](qmessagebox.html#exec)()槽返回[StandardButtons](qmessagebox.html#StandardButton-enum)单击的按钮的值。
```
switch (ret) {
case QMessageBox.Save:
// Save was clicked
break;
case QMessageBox.Discard:
// Don't Save was clicked
break;
case QMessageBox.Cancel:
// Cancel was clicked
break;
default:
// should never be reached
break;
}
```
为了给用户更多的信息,以帮助他回答这个问题,设置[detailed text](qmessagebox.html#detailedText-prop)属性。如果[detailed text](qmessagebox.html#detailedText-prop)属性设置,**Show Details...**将显示按钮。
![](https://img.kancloud.cn/19/70/1970bbfab9356a81a780949017bad2ad_467x128.png)
点击**Show Details...**按钮将显示详细的文字。
![](https://img.kancloud.cn/4b/d4/4bd49f73ca9e0b58c9a5fd4c7cefeaa5_466x245.png)
#### Rich Text and the Text Format Property
该[detailed text](qmessagebox.html#detailedText-prop)属性总是被解释为纯文本。该[main text](qmessagebox.html#text-prop)和[informative text](qmessagebox.html#informativeText-prop)性能可以是纯文本或富文本。这些字符串是根据所设定的解释[text format](qmessagebox.html#textFormat-prop)属性。默认设置为[auto-text](qt.html#TextFormat-enum)。
请注意,对于包含XML的元字符的一些纯文本字符串,自动文本[rich text detection test](qt.html#mightBeRichText)可能会失败,从而导致你的纯文本字符串被错误地解释为富文本。在这些罕见的情况下,使用[Qt.convertFromPlainText](qt.html#convertFromPlainText)( )到您的纯文本字符串转换为等效的视觉丰富的文本字符串,或将[text format](qmessagebox.html#textFormat-prop)属性明确与[setTextFormat](qmessagebox.html#textFormat-prop)( ) 。
#### Severity Levels and the Icon and Pixmap Properties
QMessageBox提示支持四种预定义的消息严重级别,或消息类型,这真的只是不同的预定义的图标,他们每场演出。通过设置指定四个预定义的消息类型之一的[icon](qmessagebox.html#icon-prop)属性的一个[predefined icons](qmessagebox.html#Icon-enum)。以下规则的指导方针:
| ![](https://img.kancloud.cn/2b/9d/2b9d222b82c662fb58a70d4a58ed200c_39x38.png) | [Question](qmessagebox.html#Icon-enum) | For asking a question during normal operations. |
| ![](https://img.kancloud.cn/63/72/63726eaa7b48d826a8426cdf14c06407_37x36.png) | [Information](qmessagebox.html#Icon-enum) | For reporting information about normal operations. |
| ![](https://img.kancloud.cn/c0/6c/c06c29f61b1dfc6e77af771a890becd6_40x39.png) | [Warning](qmessagebox.html#Icon-enum) | For reporting non-critical errors. |
| ![](https://img.kancloud.cn/54/62/54629565b203a26603fb2b76a5abfaf0_37x36.png) | [Critical](qmessagebox.html#Icon-enum) | For reporting critical errors. |
[Predefined icons](qmessagebox.html#Icon-enum)不受QMessageBox提示定义的,而是由式提供。缺省值是[No Icon](qmessagebox.html#Icon-enum)。该消息框,否则相同的所有案件。当使用一个标准的图标,推荐使用表中的一个,或者使用建议您使用平台的风格准则之一。如果没有一个标准的图标是适合你的消息框,你可以通过设置使用自定义图标[icon pixmap](qmessagebox.html#iconPixmap-prop)财产,而不是设置[icon](qmessagebox.html#icon-prop)属性。
总之,要设置一个图标,用_either_ [setIcon](qmessagebox.html#icon-prop)( )为标准图标之一,_or_ [setIconPixmap](qmessagebox.html#iconPixmap-prop)()为一个自定义图标。
### The Static Functions API
建立消息框与静态函数的API,虽然方便,比使用基于属性的API,弹性较差,因为静态函数签名缺少用于设置参数[informative text](qmessagebox.html#informativeText-prop)和[detailed text](qmessagebox.html#detailedText-prop)属性。一个工作围绕这一直使用`title`参数为消息框正文及`text`参数为消息框翔实的文字。因为这具有使一个不太可读的消息框的明显缺点,平台指引不建议这样做。该_Microsoft Windows User Interface Guidelines_建议使用[application name](qcoreapplication.html#applicationName-prop)作为[window's title](qmessagebox.html#setWindowTitle),这意味着,如果你有除了你的主文本的信息文本,你必须将它连接到`text`参数。
注意,静态函数签名,相对于它们的键参数,而现在用于设置改变[standard buttons](qmessagebox.html#standardButtons-prop)和[default button](qmessagebox.html#defaultButton)。
静态函数可用于创建[information](qmessagebox.html#information)( )[question](qmessagebox.html#question)( )[warning](qmessagebox.html#warning)()和[critical](qmessagebox.html#critical)( )消息框。
```
int ret = QMessageBox.warning(this, tr("My Application"),
tr("The document has been modified.\n"
"Do you want to save your changes?"),
QMessageBox.Save | QMessageBox.Discard
| QMessageBox.Cancel,
QMessageBox.Save);
```
该[Standard Dialogs](index.htm)示例显示了如何使用QMessageBox提示和其他内置Qt对话框。
### Advanced Usage
如果[standard buttons](qmessagebox.html#StandardButton-enum)不够灵活,你的消息框,您可以使用[addButton](qmessagebox.html#addButton)( )过载,需要一个文本和一个ButtonRoleto添加自定义按钮。该[ButtonRole](qmessagebox.html#ButtonRole-enum)所使用QMessageBox提示来确定屏幕上的按钮的顺序(它根据平台而异)。您可以测试的价值[clickedButton](qmessagebox.html#clickedButton)( )调用后[exec_](qmessagebox.html#exec)( ) 。例如,
```
QMessageBox msgBox;
[QPushButton](qpushbutton.html) *connectButton = msgBox.addButton(tr("Connect"), QMessageBox.ActionRole);
[QPushButton](qpushbutton.html) *abortButton = msgBox.addButton(QMessageBox.Abort);
msgBox.exec_();
if (msgBox.clickedButton() == connectButton) {
// connect
} else if (msgBox.clickedButton() == abortButton) {
// abort
}
```
### Default and Escape Keys
默认按钮(即按钮激活时,**Enter**被按下)可以使用被指定[setDefaultButton](qmessagebox.html#setDefaultButton)( ) 。如果没有指定一个缺省按钮, QMessageBox提示试图找到一个基于所述[button roles](qmessagebox.html#ButtonRole-enum)在消息框中使用的按钮。
逃生按钮(按钮激活时,**Esc**被按下)可以使用被指定[setEscapeButton](qmessagebox.html#setEscapeButton)( ) 。如果未指定逃跑按钮, QMessageBox提示尝试使用这些规则,以找到一个:
1. 如果只有一个按钮,它是激活的按钮时**Esc**被按下。
2. 如果有一个[Cancel](qmessagebox.html#StandardButton-enum)按钮,它是激活按钮时**Esc**被按下。
3. 如果恰好有一个按钮有两种[the Reject role](qmessagebox.html#ButtonRole-enum)或[the No role](qmessagebox.html#ButtonRole-enum),它是在按钮被激活时**Esc**被按下。
当不能使用这些规则,按确定的逃生按钮**Esc**没有任何影响。
