## Detailed Description
该的QTextEdit类提供用于编辑和显示两个平原和丰富的文本控件。
### Introduction and Concepts
的QTextEdit是一种先进的所见即所得的浏览器/编辑器,支持丰富的文本格式使用HTML风格的标籤。这是优化处理大型文件,并快速响应用户输入。
QTextEdit一起工作的段落和字符。一个段落是一个格式化字符串,它是自动换行以适应窗口部件的宽度。通过阅读纯文本时,默认情况下,有一个换行符表示一个段落。文档包含零个或多个段落。段落中的单词排列按照段落的对齐方式。段落是由硬换行符分隔。一个段内的每个字符具有其自己的属性,例如,字体和颜色。
的QTextEdit可以显示图像,列表和表格。如果文本太大无法查看文本编辑的视口内,滚动条就会出现。文本编辑可以加载纯文本和HTML文件( HTML 3.2的子集和4 ) 。
如果你只是需要显示一小块富文本使用[QLabel](qlabel.html)。
在Qt的富文本支持旨在提供一种快速,便携,高效的方式来合理的在线帮助工具添加到应用程序,并提供丰富的文本编辑器的基础。如果您发现该HTML支持不足,为您的需求,您可以考虑使用[QtWebKit](index.htm),它提供了一个全功能的Web浏览器控件。
鼠标光标的上一个的QTextEdit的形状是[Qt.IBeamCursor](qt.html#CursorShape-enum)在默认情况下。它可以通过改变该[viewport](qabstractscrollarea.html#viewport)( )的游标属性。
### Using QTextEdit as a Display Widget
的QTextEdit可以显示一个大的HTML子集,包括表格和图像。
全文载或更换使用[setHtml](qtextedit.html#html-prop)(),它会删除任何现有文本,并与所传递的文本替换它[setHtml](qtextedit.html#html-prop)( )调用。如果你打电话[setHtml](qtextedit.html#html-prop)( )与传统的HTML ,然后调用[toHtml](qtextedit.html#html-prop)( ) ,返回的文本可能有不同的标记,但会呈现相同的。整个文本可以被删除[clear](qtextedit.html#clear)( ) 。
文本本身可以使用插入的[QTextCursor](qtextcursor.html)类或者使用的方便功能[insertHtml](qtextedit.html#insertHtml)( )[insertPlainText](qtextedit.html#insertPlainText)( )[append](qtextedit.html#append)()或[paste](qtextedit.html#paste)( ) 。[QTextCursor](qtextcursor.html)也能像插入表格或列表的复杂对象插入到文档中,它处理创建的选择和应用更改选定的文本。
默认情况下,文本编辑换行的空白,以适应文本编辑窗口部件。该[setLineWrapMode](qtextedit.html#lineWrapMode-prop)( )函数是用来指定你想要的那种换行的,或[NoWrap](qtextedit.html#LineWrapMode-enum)如果你不希望任何包装。通话[setLineWrapMode](qtextedit.html#lineWrapMode-prop)( )来设置一个固定像素宽度[FixedPixelWidth](qtextedit.html#LineWrapMode-enum),或字符列(例如80列)[FixedColumnWidth](qtextedit.html#LineWrapMode-enum)与指定的像素或列[setLineWrapColumnOrWidth](qtextedit.html#lineWrapColumnOrWidth-prop)( ) 。如果您使用自动换行到Widget的宽度[WidgetWidth](qtextedit.html#LineWrapMode-enum),您可以指定是否要与打破空白或任何地方[setWordWrapMode](qtextedit.html#wordWrapMode-prop)( ) 。
该[find](qtextedit.html#find)( )函数可以用来查找和选择文本中给定的字符串。
如果你想限制在一个的QTextEdit段的总数,例如它往往是在日志查看器有用,那么你可以使用[QTextDocument](qtextdocument.html)的maximumBlockCount属性的。
#### Read-only Key Bindings
当QTextEdit一起使用只读的键绑定仅限于导航和文字可能只用鼠标进行选择:
| Keypresses | Action |
| --- | --- |
| Up | Moves one line up. |
| Down | Moves one line down. |
| Left | Moves one character to the left. |
| Right | Moves one character to the right. |
| PageUp | Moves one (viewport) page up. |
| PageDown | Moves one (viewport) page down. |
| Home | Moves to the beginning of the text. |
| End | Moves to the end of the text. |
| Alt+Wheel | Scrolls the page horizontally (the Wheel is the mouse wheel). |
| Ctrl+Wheel | Zooms the text. |
| Ctrl+A | Selects all text. |
文本编辑可能能够提供一些元信息。例如,本[documentTitle](qtextedit.html#documentTitle-prop)( )函数将来自内部的HTML返回文本`<title>`标籤。
### Using QTextEdit as an Editor
所有有关使用的QTextEdit作为一个显示插件的信息也适用于这里。
目前char格式的属性设置[setFontItalic](qtextedit.html#setFontItalic)( )[setFontWeight](qtextedit.html#setFontWeight)( )[setFontUnderline](qtextedit.html#setFontUnderline)( )[setFontFamily](qtextedit.html#setFontFamily)( )[setFontPointSize](qtextedit.html#setFontPointSize)( )[setTextColor](qtextedit.html#setTextColor)()和[setCurrentFont](qtextedit.html#setCurrentFont)( ) 。当前段落的对齐方式设置与[setAlignment](qtextedit.html#setAlignment)( ) 。
选择文本是由处理[QTextCursor](qtextcursor.html)类,它用于创建选择,检索的文本内容或删除选项提供的功能。你可以检索与用户可见的光标使用相对应的对象[textCursor](qtextedit.html#textCursor)()方法。如果你想设置一个选择使用QTextEdit只需要建立一个上一个[QTextCursor](qtextcursor.html)对象,然后使该游标使用游标可见[setTextCursor](qtextedit.html#setTextCursor)( ) 。选择可以复制到剪贴板[copy](qtextedit.html#copy)( ) ,或剪切到剪贴板[cut](qtextedit.html#cut)( ) 。整个文本可以使用选择[selectAll](qtextedit.html#selectAll)( ) 。
当光标被移动和底层的格式属性的变化,[currentCharFormatChanged](qtextedit.html#currentCharFormatChanged)()信号被发射,以反映新的光标位置处的新的属性。
的QTextEdit持有[QTextDocument](qtextdocument.html)这可以使用被检索对象的[document](qtextedit.html#document)()方法。您也可以使用设置自己的文档对象[setDocument](qtextedit.html#setDocument)( ) 。[QTextDocument](qtextdocument.html)发出[textChanged](qtextedit.html#textChanged)( )信号,如果文本的变化,它也提供了一个[isModified](index.htm#isModified)( )函数,如果文本已经被修改,因为它是在加载或自上次调用SetModified之用False作为参数,该参数将返回True 。此外,它还提供了撤销和重做的方法。
#### Drag and Drop
的QTextEdit还支持自定义拖放行为。默认情况下,会的QTextEdit当用户删除这些MIME类型的数据到一个文档中插入纯文本, HTML和RTF 。重新实现[canInsertFromMimeData](qtextedit.html#canInsertFromMimeData)()和[insertFromMimeData](qtextedit.html#insertFromMimeData)()来添加额外的MIME类型的支持。
例如,为了允许用户拖放图像投影到的QTextEdit ,你可以在以下面的方式实现这些功能:
```
bool TextEdit.canInsertFromMimeData( const [QMimeData](qmimedata.html) *source ) const
{
if (source->hasImage())
return true;
else
return QTextEdit.canInsertFromMimeData(source);
}
```
我们通过返回True添加图像的MIME类型的支持。对于所有其他的MIME类型,我们使用默认的实现。
```
void TextEdit.insertFromMimeData( const [QMimeData](qmimedata.html) *source )
{
if (source->hasImage())
{
[QImage](qimage.html) image = qvariant_cast<[QImage](qimage.html)>(source->imageData());
[QTextCursor](qtextcursor.html) cursor = this->textCursor();
[QTextDocument](qtextdocument.html) *document = this->document();
document->addResource([QTextDocument](qtextdocument.html).ImageResource, [QUrl](qurl.html)("image"), image);
cursor.insertImage("image");
}
}
```
我们解压缩图像从[QVariant](qvariant.html)由MIME源举行,并将其插入到文档中作为一个资源。
#### Editing Key Bindings
这是实施进行编辑键绑定列表:
| Keypresses | Action |
| --- | --- |
| Backspace | Deletes the character to the left of the cursor. |
| Delete | Deletes the character to the right of the cursor. |
| Ctrl+C | Copy the selected text to the clipboard. |
| Ctrl+Insert | Copy the selected text to the clipboard. |
| Ctrl+K | Deletes to the end of the line. |
| Ctrl+V | Pastes the clipboard text into text edit. |
| Shift+Insert | Pastes the clipboard text into text edit. |
| Ctrl+X | Deletes the selected text and copies it to the clipboard. |
| Shift+Delete | Deletes the selected text and copies it to the clipboard. |
| Ctrl+Z | Undoes the last operation. |
| Ctrl+Y | Redoes the last operation. |
| Left | Moves the cursor one character to the left. |
| Ctrl+Left | Moves the cursor one word to the left. |
| Right | Moves the cursor one character to the right. |
| Ctrl+Right | Moves the cursor one word to the right. |
| Up | Moves the cursor one line up. |
| Down | Moves the cursor one line down. |
| PageUp | Moves the cursor one page up. |
| PageDown | Moves the cursor one page down. |
| Home | Moves the cursor to the beginning of the line. |
| Ctrl+Home | Moves the cursor to the beginning of the text. |
| End | Moves the cursor to the end of the line. |
| Ctrl+End | Moves the cursor to the end of the text. |
| Alt+Wheel | Scrolls the page horizontally (the Wheel is the mouse wheel). |
选择(标记)的文本按住Shift键的同时按下按键的运动之一,例如,_Shift+Right_将选择的字符的权利,_Shift+Ctrl+Right_将选择字的右边,等。
