我在mysql数据库的表中显示数据, 之后,我想在单击表中的行时,它将打印行中的值,即打印id数据库中的现有数据。我如何让它成为那样的?
这是源代码:
from PyQt4 import QtCore, QtGui
import sys
import MySQLdb
from form.DBConnection import Connection
import MySQLdb as mdb
db = Connection()
myCursor = db.name().cursor()
” .............................................. .. .....................................“
class Ui_MainWindow(object):
def setupUi(self, MainWindow):
MainWindow.setObjectName(_fromUtf8("MainWindow"))
MainWindow.resize(655, 356)
self.centralwidget = QtGui.QWidget(MainWindow)
self.centralwidget.setObjectName(_fromUtf8("centralwidget"))
self.tbl_anggota = QtGui.QTableWidget(self.centralwidget)
self.tbl_anggota.setGeometry(QtCore.QRect(15, 40, 511, 192))
self.tbl_anggota.setObjectName(_fromUtf8("tbl_anggota"))
self.tbl_anggota.setColumnCount(3)
self.tbl_anggota.setRowCount(0)
item = QtGui.QTableWidgetItem()
self.tbl_anggota.setHorizontalHeaderItem(0, item)
item = QtGui.QTableWidgetItem()
self.tbl_anggota.setHorizontalHeaderItem(1, item)
item = QtGui.QTableWidgetItem()
self.tbl_anggota.setHorizontalHeaderItem(2, item)
MainWindow.setCentralWidget(self.centralwidget)
self.menubar = QtGui.QMenuBar(MainWindow)
self.menubar.setGeometry(QtCore.QRect(0, 0, 655, 21))
self.menubar.setObjectName(_fromUtf8("menubar"))
MainWindow.setMenuBar(self.menubar)
self.statusbar = QtGui.QStatusBar(MainWindow)
self.statusbar.setObjectName(_fromUtf8("statusbar"))
MainWindow.setStatusBar(self.statusbar)
self.retranslateUi(MainWindow)
self.table(MainWindow)
QtCore.QMetaObject.connectSlotsByName(MainWindow)
def retranslateUi(self, MainWindow):
MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow", None))
item = self.tbl_anggota.horizontalHeaderItem(0)
item.setText(_translate("MainWindow", "NIM", None))
item = self.tbl_anggota.horizontalHeaderItem(1)
item.setText(_translate("MainWindow", "NAMA", None))
item = self.tbl_anggota.horizontalHeaderItem(2)
def table(self, MainWindow):
myCursor.execute("SELECT * FROM anggota")
jum_baris= myCursor.fetchall()
self.tbl_anggota.setRowCount(len(jum_baris))
self.tbl_anggota.setColumnCount(3)
for i in range (len(jum_baris)):
for j in range (3):
item = Qt.QTableWidgetItem('%s' % (jum_baris[i][j + 1]))
self.tbl_anggota.setItem(i, j, item)
if __name__ == "__main__":
app = QtGui.QApplication(sys.argv)
MainWindow = QtGui.QMainWindow()
ui = Ui_MainWindow()
ui.setupUi(MainWindow)
MainWindow.show()
sys.exit(app.exec_())
答案 0 :(得分:2)
这行代码将选择current row
r = self.tbl_anggota.currentRow()
如果您知道列(即它不是动态的),则可以通过执行以下操作来提取每个单元格的值:
field1 = self.tbl_anggota.item(r,0).text()
field2 = self.tbl_anggota.item(r,1).text()
在这种情况下,item调用中的0
和1
是您的列,位于0索引数组中。请记住,隐藏的列仍然有效。
要在点击一行时自动执行此操作,您将要使用信号itemClicked
