所以,我正在使用PythonPyQt,并创建了一个QTableWidget我用数据填充的。

有没有办法搜索一个特定的值,如果程序找到一些东西,它可以返回coordinated(index)项目的值吗?

这是代码:

你能看出有什么错误吗?很抱歉,但我不确定哪一部分是错的……我剪掉了一些不重要的部分……

用于QTableWidget.findItems获取匹配列表,QTableWidgetItems然后可以查询它们的坐标。

这是一个简单的演示脚本:

from PyQt4 import QtGui, QtCore

class Window(QtGui.QWidget):
    def __init__(self, rows, columns):
        QtGui.QWidget.__init__(self)
        self.table = QtGui.QTableWidget(self)
        self.table.setRowCount(rows)
        self.table.setColumnCount(columns)
        for column in range(columns):
            for row in range(rows):
                item = QtGui.QTableWidgetItem('Text%d' % row)
                self.table.setItem(row, column, item)
        self.edit = QtGui.QLineEdit(self)
        self.button = QtGui.QPushButton('Search', self)
        self.button.clicked.connect(self.handleButton)
        layout = QtGui.QVBoxLayout(self)
        layout.addWidget(self.table)
        layout.addWidget(self.edit)
        layout.addWidget(self.button)

    def handleButton(self):
        items = self.table.findItems(
            self.edit.text(), QtCore.Qt.MatchExactly)
        if items:
            results = '\n'.join(
                'row %d column %d' % (item.row() + 1, item.column() + 1)
                for item in items)
        else:
            results = 'Found Nothing'
        QtGui.QMessageBox.information(self, 'Search Results', results)

if __name__ == '__main__':

    import sys
    app = QtGui.QApplication(sys.argv)
    window = Window(6, 3)
    window.resize(350, 300)
    window.show()
    sys.exit(app.exec_())

如果你在 QTableWidget 中使用 QTableWidgetItems 那么你可以使用这个:

for row in xrange(table.rowCount ()):
   for column in xrange(table.columnCount ()):
       item = table.item (row, column )
       if item and item.data (Qt.DisplayRole) == "my_search_value":
           return table.indexFromItem (item)
 return None
