The QTextOption class provides a description of general rich text properties.
QTextOption is used to encapsulate common rich text properties in a single object. It contains information about text alignment, layout direction, word wrapping, and other standard properties associated with text rendering and layout.
| 常量 | 值 | 描述 |
|---|---|---|
| QTextOption.IncludeTrailingSpaces | 0x80000000 | When this option is set, QTextLine.naturalTextWidth () and naturalTextRect() will return a value that includes the width of trailing spaces in the text; otherwise this width is excluded. |
| QTextOption.ShowTabsAndSpaces | 0x1 | Visualize spaces with little dots, and tabs with little arrows. |
| QTextOption.ShowLineAndParagraphSeparators | 0x2 | Visualize line and paragraph separators with appropriate symbol characters. |
| QTextOption.AddSpaceForLineAndParagraphSeparators | 0x4 | While determining the line-break positions take into account the space added for drawing a separator character. |
| QTextOption.SuppressColors | 0x8 | Suppress all color changes in the character formats (except the main selection). |
Flags 类型是 typedef 对于 QFlags <Flag>. It stores an OR combination of Flag values.
此枚举包含不同类型的制表符
| 常量 | 值 | 描述 |

| QTextOption.LeftTab | 0 | 左 Tab |
| QTextOption.RightTab | 1 | 右 Tab |
| QTextOption.CenterTab | 2 | 居中 Tab |

此枚举描述文本如何在文档中换行。
| 常量 | 值 | 描述 |
|---|---|---|
| QTextOption.NoWrap | 0 | 文本根本不换行。 |
| QTextOption.WordWrap | 1 | 文本在单词边界处换行。 |
| QTextOption.ManualWrap | 2 | Same as QTextOption.NoWrap |
| QTextOption.WrapAnywhere | 3 | Text can be wrapped at any point on a line, even if it occurs in the middle of a word. |
| QTextOption.WrapAtWordBoundaryOrAnywhere | 4 | If possible, wrapping occurs at a word boundary; otherwise it will occur at the appropriate point on the line, even in the middle of a word. |
Constructs a text option with default properties for text. The text alignment property is set to Qt.AlignLeft . The word wrap property is set to QTextOption.WordWrap 。 using of design metrics flag is set to false.
构造文本选项采用给定 alignment for text. The word wrap property is set to QTextOption.WordWrap 。 using of design metrics flag is set to false.
