QT4 表
我們可以使用 QTableWidget
顯示一個表,它是PyQt 模組的一部分。我們可以設定標題,行數,列數並新增資料。
Qt4 表示例
以下示例:
from PyQt4.QtGui import *
from PyQt4.QtCore import *
import sys
def main():
app = QApplication(sys.argv)
table = QTableWidget()
tableItem = QTableWidgetItem()
# initiate table
table.setWindowTitle("QTableWidget Example @pythonspot.com")
table.resize(400, 250)
table.setRowCount(4)
table.setColumnCount(2)
# set data
table.setItem(0,0, QTableWidgetItem("Item (1,1)"))
table.setItem(0,1, QTableWidgetItem("Item (1,2)"))
table.setItem(1,0, QTableWidgetItem("Item (2,1)"))
table.setItem(1,1, QTableWidgetItem("Item (2,2)"))
table.setItem(2,0, QTableWidgetItem("Item (3,1)"))
table.setItem(2,1, QTableWidgetItem("Item (3,2)"))
table.setItem(3,0, QTableWidgetItem("Item (4,1)"))
table.setItem(3,1, QTableWidgetItem("Item (4,2)"))
# show table
table.show()
return app.exec_()
if __name__ == '__main__':
main()
結果:
QTableWidget 標籤
你可以使用 setHorizontalHeaderLabels()
函式設定標頭。這同樣適用於垂直標籤。下面的演示:
from PyQt4.QtGui import *
from PyQt4.QtCore import *
import sys
def main():
app = QApplication(sys.argv)
table = QTableWidget()
tableItem = QTableWidgetItem()
# initiate table
table.setWindowTitle("QTableWidget Example @pythonspot.com")
table.resize(400, 250)
table.setRowCount(4)
table.setColumnCount(2)
# set label
table.setHorizontalHeaderLabels(QString("H1;H2;").split(";"))
table.setVerticalHeaderLabels(QString("V1;V2;V3;V4").split(";"))
# set data
table.setItem(0,0, QTableWidgetItem("Item (1,1)"))
table.setItem(0,1, QTableWidgetItem("Item (1,2)"))
table.setItem(1,0, QTableWidgetItem("Item (2,1)"))
table.setItem(1,1, QTableWidgetItem("Item (2,2)"))
table.setItem(2,0, QTableWidgetItem("Item (3,1)"))
table.setItem(2,1, QTableWidgetItem("Item (3,2)"))
table.setItem(3,0, QTableWidgetItem("Item (4,1)"))
table.setItem(3,1, QTableWidgetItem("Item (4,2)"))
# show table
table.show()
return app.exec_()
if __name__ == '__main__':
main()
結果:
QTableWidget 單擊事件
我們可以使用此過程檢測單元格點選,首先新增一個函式:
# on click function
table.cellClicked.connect(cellClick)
然後定義函式:
def cellClick(row,col):
print "Click on " + str(row) + " " + str(col)
Python 程式語言從 0 開始計數,所以當你按(1,1)時你會看到(0,0)。檢測表單擊的完整程式碼:
from PyQt4.QtGui import *
from PyQt4.QtCore import *
import sys
def cellClick(row,col):
print "Click on " + str(row) + " " + str(col)
def main():
app = QApplication(sys.argv)
table = QTableWidget()
tableItem = QTableWidgetItem()
# initiate table
table.setWindowTitle("QTableWidget Example @pythonspot.com")
table.resize(400, 250)
table.setRowCount(4)
table.setColumnCount(2)
# set label
table.setHorizontalHeaderLabels(QString("H1;H2;").split(";"))
table.setVerticalHeaderLabels(QString("V1;V2;V3;V4").split(";"))
# set data
table.setItem(0,0, QTableWidgetItem("Item (1,1)"))
table.setItem(0,1, QTableWidgetItem("Item (1,2)"))
table.setItem(1,0, QTableWidgetItem("Item (2,1)"))
table.setItem(1,1, QTableWidgetItem("Item (2,2)"))
table.setItem(2,0, QTableWidgetItem("Item (3,1)"))
table.setItem(2,1, QTableWidgetItem("Item (3,2)"))
table.setItem(3,0, QTableWidgetItem("Item (4,1)"))
table.setItem(3,1, QTableWidgetItem("Item (4,2)"))
# on click function
table.cellClicked.connect(cellClick)
# show table
table.show()
return app.exec_()
if __name__ == '__main__':
main()
如果要以非程式設計師方式顯示單元格/行號,請使用以下程式碼:
def cellClick(row,col):
print "Click on " + str(row+1) + " " + str(col+1)
工具提示文字
我們可以使用該方法設定工具提示(滑鼠懸停)文字。如果在不存在的列上設定工具提示,則會出現錯誤。
from PyQt4.QtGui import *
from PyQt4.QtCore import *
import sys
def main():
app = QApplication(sys.argv)
table = QTableWidget()
tableItem = QTableWidgetItem()
# initiate table
table.setWindowTitle("QTableWidget Example @pythonspot.com")
table.resize(400, 250)
table.setRowCount(4)
table.setColumnCount(2)
# set label
table.setHorizontalHeaderLabels(QString("H1;H2;").split(";"))
table.setVerticalHeaderLabels(QString("V1;V2;V3;V4").split(";"))
# set data
table.setItem(0,0, QTableWidgetItem("Item (1,1)"))
table.setItem(0,1, QTableWidgetItem("Item (1,2)"))
table.setItem(1,0, QTableWidgetItem("Item (2,1)"))
table.setItem(1,1, QTableWidgetItem("Item (2,2)"))
table.setItem(2,0, QTableWidgetItem("Item (3,1)"))
table.setItem(2,1, QTableWidgetItem("Item (3,2)"))
table.setItem(3,0, QTableWidgetItem("Item (4,1)"))
table.setItem(3,1, QTableWidgetItem("Item (4,2)"))
# tooltip text
table.horizontalHeaderItem(0).setToolTip("Column 1 ")
table.horizontalHeaderItem(1).setToolTip("Column 2 ")
# show table
table.show()
return app.exec_()
if __name__ == '__main__':
main()
結果:
