## Detailed Description
该QPlainTextEdit类提供用于编辑和显示纯文本的小工具。
### Introduction and Concepts
QPlainTextEdit是一种先进的浏览器/编辑器,支持纯文本。这是优化处理大型文件,并快速响应用户输入。
QPlainText使用非常相同的技术和概念[QTextEdit](qtextedit.html),但最适用于纯文本的处理。
QPlainTextEdit工程对段落和字符。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。
鼠标光标的上一个QPlainTextEdit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 QPlainTextEdit as a Display Widget
全文载或更换使用[setPlainText](qplaintextedit.html#plainText-prop)(),它会删除现有的文本和传递给文本替换它[setPlainText](qplaintextedit.html#plainText-prop)( ) 。
文本可以使用插入的[QTextCursor](qtextcursor.html)类或者使用的方便功能[insertPlainText](qplaintextedit.html#insertPlainText)( )[appendPlainText](qplaintextedit.html#appendPlainText)()或[paste](qplaintextedit.html#paste)( ) 。
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](qplaintextedit.html#lineWrapMode-prop)( )函数是用来指定你想要的那种线包裹,[WidgetWidth](qplaintextedit.html#LineWrapMode-enum) or [NoWrap](qplaintextedit.html#LineWrapMode-enum)如果你不希望任何包装。如果您使用自动换行到Widget的宽度[WidgetWidth](qplaintextedit.html#LineWrapMode-enum),您可以指定是否要与打破空白或任何地方[setWordWrapMode](qplaintextedit.html#wordWrapMode-prop)( ) 。
该[find](qplaintextedit.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QPlainTextEdit段的总数,因为它是例如在日志查看器有用,那么你可以使用[maximumBlockCount](qplaintextedit.html#maximumBlockCount-prop)属性。的组合[setMaximumBlockCount](qplaintextedit.html#maximumBlockCount-prop)()和[appendPlainText](qplaintextedit.html#appendPlainText)( )将QPlainTextEdit成一个高效的查看器日志文本。滚动可减少与[centerOnScroll](qplaintextedit.html#centerOnScroll-prop)()属性,使得日志查看器更快。文字可以以有限的方式进行格式化,或者使用语法高亮显示(见下文) ,或通过添加HTML格式的文本与[appendHtml](qplaintextedit.html#appendHtml)( ) 。虽然QPlainTextEdit不支持复杂的富文本渲染的表和浮筒,它的确支持,您可能需要在日志查看器有限段落为基础的格式。
#### Read-only Key Bindings
当QPlainTextEdit用于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 |
| --- | --- |
| [Qt.UpArrow](qt.html#ArrowType-enum) | Moves one line up. |
| [Qt.DownArrow](qt.html#ArrowType-enum) | Moves one line down. |
| [Qt.LeftArrow](qt.html#ArrowType-enum) | Moves one character to the left. |
| [Qt.RightArrow](qt.html#ArrowType-enum) | 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. |
### Using QPlainTextEdit as an Editor
关于使用QPlainTextEdit作为显示插件的信息也适用于这里。
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](qplaintextedit.html#textCursor)()方法。如果你想设置一个选择在QPlainTextEdit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[setCursor](qwidget.html#cursor-prop)( ) 。选择可以复制到剪贴板[copy](qplaintextedit.html#copy)( ) ,或剪切到剪贴板[cut](qplaintextedit.html#cut)( ) 。整个文本可以使用选择[selectAll](qplaintextedit.html#selectAll)( ) 。
QPlainTextEdit持有[QTextDocument](qtextdocument.html)这可以使用被检索对象的[document](qplaintextedit.html#document)()方法。您也可以使用设置自己的文档对象[setDocument](qplaintextedit.html#setDocument)( ) 。[QTextDocument](qtextdocument.html)发出[textChanged](qplaintextedit.html#textChanged)( )信号,如果文本的变化,它也提供了一个通过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。
#### Syntax Highlighting
一样[QTextEdit](qtextedit.html), QPlainTextEdit作品连同[QSyntaxHighlighter](qsyntaxhighlighter.html)。
#### 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. |
| LeftArrow | Moves the cursor one character to the left. |
| Ctrl+LeftArrow | Moves the cursor one word to the left. |
| RightArrow | Moves the cursor one character to the right. |
| Ctrl+RightArrow | Moves the cursor one word to the right. |
| UpArrow | Moves the cursor one line up. |
| Ctrl+UpArrow | Moves the cursor one word up. |
| DownArrow | Moves the cursor one line down. |
| Ctrl+Down Arrow | Moves the cursor one word 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). |
| Ctrl+Wheel | Zooms the text. |
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 Arrow_将选择的字符的权利,_Shift+Ctrl+Right Arrow_将选择字的右边,等。
### Differences to QTextEdit
QPlainTextEdit是很薄的类,使用最是背后的技术实现[QTextEdit](qtextedit.html)和[QTextDocument](qtextdocument.html)。其性能优势比[QTextEdit](qtextedit.html)利用所谓的不同和简化的文本布局大多是干[QPlainTextDocumentLayout](qplaintextdocumentlayout.html)在文本文档(见[QTextDocument.setDocumentLayout](qtextdocument.html#setDocumentLayout)())。纯文本文档布局不支持表也不嵌入式框架,并_replaces a pixel-exact height calculation with a line-by-line respectively paragraph-by-paragraph scrolling approach_。这使得它可以处理显着较大的文档,而且还调整与实时启用自动换行的编辑器。这也使得快速日志查看器(见[setMaximumBlockCount](qplaintextedit.html#maximumBlockCount-prop)())。

void blockCountChanged (int)
```
这是该信号的默认超载。
这个信号被发射时的块数的变化。新的块数被传递_newBlockCount_。
```
void copyAvailable (bool)
```
这是该信号的默认超载。
当选择文本或文本编辑取消选择,这个信号被发射。
当选择文本这个信号将被发射_yes_设置为True 。如果没有文本被选中,或者如果选定的文本被取消选择这个信号被发射与_yes_设置为False 。
](qtextoption.html#WrapMode-enum)
[If _yes_是真的,那么](qtextoption.html#WrapMode-enum)[copy](qplaintextedit.html#copy)( )可以用来选择复制到剪贴板。如果_yes_为False,则[copy](qplaintextedit.html#copy)( )什么也不做。
**See also** [selectionChanged](qplaintextedit.html#selectionChanged)( ) 。
```
void cursorPositionChanged ()
```
这是该信号的默认超载。
这个信号被发射时的光标的位置改变。
```
void modificationChanged (bool)
```
这是该信号的默认超载。
这个信号被发射时在文档的内容改变了,影响到修改状态的方法。如果_changed_诚然,该文件已被修改,否则为假。
例如,调用SetModified之(假)上的文档,然后插入文本引起来获得所发出的信号。如果撤消操作,使所述的文件返回到其原始未修饰的状态下,信号将得到再次发射。
```
void redoAvailable (bool)
```
这是该信号的默认超载。
这个信号被发射时重做操作变得可用(_available_为True)或不可用(_available_是假的) 。
```
void selectionChanged ()
```
这是该信号的默认超载。
这个信号被发射时的选择改变。
**See also** [copyAvailable](qplaintextedit.html#copyAvailable)( ) 。
```
void textChanged ()
```
这是该信号的默认超载。
这个信号被发射时该文档的内容更改,例如,当文本被插入或删除,或格式化时被应用。
```
void undoAvailable (bool)
```
这是该信号的默认超载。
这个信号被发射时撤销操作变得可用(_available_为True)或不可用(_available_是假的) 。
```
void updateRequest (const QRect&,int)
```
这是该信号的默认超载。
当文本文档需要指定的更新这个信号被发射_rect_。如果文字滚动,_rect_将复盖整个视口区域。如果文本是垂直滚动,_dy_进行像素的视口已滚动的量。
信号的目的是支持在该如纯文本编辑子类额外的部件显示行号,断点,或其他额外的信息。
