详细描述

Table cells are pieces of document structure that belong to a table. The table orders cells into particular rows and columns; cells can also span multiple columns and rows.

Cells are usually created when a table is inserted into a document with QTextCursor::insertTable (), but they are also created and destroyed when a table is resized.

Cells contain information about their location in a table; you can obtain the row () 和 column () numbers of a cell, and its rowSpan () 和 columnSpan ().

The format () of a cell describes the default character format of its contents. The firstCursorPosition () 和 lastCursorPosition () functions are used to obtain the extent of the cell in the document.

成员函数文档编制

QTextTableCell:: QTextTableCell ()

Constructs an invalid table cell.

另请参阅 isValid ().

QTextTableCell:: QTextTableCell (const QTextTableCell & other )

Copy constructor. Creates a new QTextTableCell object based on the other cell.

QTextTableCell:: ~QTextTableCell ()

Destroys the table cell.

QTextFrame::iterator QTextTableCell:: begin () const

Returns a frame iterator pointing to the beginning of the table's cell.

另请参阅 end ().

int QTextTableCell:: column () const

Returns the number of the column in the table that contains this cell.

另请参阅 row ().

int QTextTableCell:: columnSpan () const

Returns the number of columns this cell spans. The default is 1.

另请参阅 rowSpan ().

QTextFrame::iterator QTextTableCell:: end () const

Returns a frame iterator pointing to the end of the table's cell.

另请参阅 begin ().

QTextCursor QTextTableCell:: firstCursorPosition () const

Returns the first valid cursor position in this cell.

另请参阅 lastCursorPosition ().

QTextCharFormat QTextTableCell:: format () const

Returns the cell's character format.

另请参阅 setFormat ().

bool QTextTableCell:: isValid () const

返回 true if this is a valid table cell; otherwise returns false.

QTextCursor QTextTableCell:: lastCursorPosition () const

Returns the last valid cursor position in this cell.

另请参阅 firstCursorPosition ().

int QTextTableCell:: row () const

Returns the number of the row in the table that contains this cell.

另请参阅 column ().

int QTextTableCell:: rowSpan () const

Returns the number of rows this cell spans. The default is 1.

另请参阅 columnSpan ().

void QTextTableCell:: setFormat (const QTextCharFormat & format )

Sets the cell's character format to format . This can for example be used to change the background color of the entire cell:

QTextTableCell cell = table->cellAt(2, 3); QTextCharFormat format = cell. format (); format.setBackground( Qt::blue ); cell.setFormat(format);

Note that the cell's row or column span cannot be changed through this function. You have to use QTextTable::mergeCells and QTextTable::splitCell 代替。

另请参阅 format ().

int QTextTableCell:: tableCellFormatIndex () const

Returns the index of the tableCell's format in the document's internal list of formats.

另请参阅 QTextDocument::allFormats ().

bool QTextTableCell:: operator!= (const QTextTableCell & other ) const

返回 true if this cell object and the other cell object describe different cells; otherwise returns false .

QTextTableCell &QTextTableCell:: operator= (const QTextTableCell & other )

赋值 other table cell to this table cell.

bool QTextTableCell:: operator== (const QTextTableCell & other ) const

返回 true if this cell object and the other cell object describe the same cell; otherwise returns false .
