qt - QTextTable 将 QTextCursor 移动到确定的单元格

Question

我有一个QTextTable，我在表格中做了一些动作，我想要两件事：

• 返回QTextCursor单元格 (0,0)

• 或移动QTextCursor到单元格（行、列）

我能怎么做？

Answer 1

对于给定table类型的对象，QTextTable获取所需的光标：

auto tableCell = table->cellAt(row, column);
auto cursor = tableCell.firstCursorPosition();

然后setTextCursor在编辑的QTextEdit对象中。

Answer 2

按照@ekhumoro 和@retmas 的建议，我这样做：

import sys
from PyQt5 import QtCore, QtGui, QtWidgets
from PyQt5.QtGui import QTextCursor

#### EKHUMORO suggestion
def move_cursor(table_text,cursor,row_destiny,col_destiny):
    row=table_text.cellAt(cursor).row()
    while not row==row_destiny:
        if row<row_destiny:
            cursor.movePosition(QTextCursor.NextRow)
        else:
            cursor.movePosition(QTextCursor.PreviousRow)
        row=table_text.cellAt(cursor).row()  
    
    col=table_text.cellAt(cursor).column()
    while not col==col_destiny:
        if col<col_destiny:
            cursor.movePosition(QTextCursor.NextCell)    
        else:
            cursor.movePosition(QTextCursor.PreviousCell)
        col=table_text.cellAt(cursor).column()


if __name__ == "__main__":
    app = QtWidgets.QApplication(sys.argv)
    widget = QtWidgets.QTextEdit()
       
    cursor=widget.textCursor()
    table_text=cursor.insertTable(10,10)

    # Format Table
    fmt = table_text.format()
    fmt.setWidth(QtGui.QTextLength(QtGui.QTextLength.PercentageLength, 100))
    table_text.setFormat(fmt)
    
    row=2
    col=5
    move_cursor(table_text,cursor,row,col)
    cursor.insertText('Cell {} {}'.format(row,col))   
    
    #### RETMAS SUGGESTION
    row=3
    column=6
    tableCell = table_text.cellAt(row, column)
    cursor = tableCell.firstCursorPosition() 
    widget.setTextCursor(cursor)
    cursor.insertText('Cell {} {}'.format(row,column))         

    widget.show()    
    sys.exit(app.exec_())

这工作正常。
