pyqt5 多个tableWidget联动滚动
项目中遇到了一个需求：
开发时用到了三个tableWidget分别展示数据，但数据过多时三个表就显得比较杂乱，三表行之间无法同时滚动必然带来不好的体验，所以需要是三个tableWidget同时滚动；
先上code：
import sys
from PyQt5.QtCore import QEvent
from PyQt5.QtWidgets import (QWidget, QTableWidget, QHeaderView, QHBoxLayout, QApplication, QTableWidgetItem,
QAbstractItemView)
class MyEvent(QEvent):
# idType = QEvent.registerEventType()
def __init__(self, data):
self.data = data
print("MyEvent.idType ", data)
def get_data(self):
return self.data
class TableWidgetDemo(QWidget):
def __init__(self):
super(TableWidgetDemo, self).__init__()
self.initUI()
def initUI(self):
self.setWindowTitle("QTableWidget演示")
self.resize(430, 230);
layout = QHBoxLayout()
tablewidget = QTableWidget()
tablewidget.setRowCount(44)
tablewidget.setColumnCount(3)
tablewidget.setHorizontalHeaderLabels(['姓名', '年龄', '籍贯'])
nameItem1 = QTableWidgetItem("张飞")
tablewidget.setItem(0, 0, nameItem1)
ageItem1 = QTableWidgetItem("24")
tablewidget.setItem(0, 1, ageItem1)
jgItem1 = QTableWidgetItem("河北")
tablewidget.setItem(0, 2, jgItem1)
nameItem2 = QTableWidgetItem("关羽")
tablewidget.setItem(1, 0, nameItem2)
ageItem2 = QTableWidgetItem("25")
tablewidget.setItem(1, 1, ageItem2)
jgItem2 = QTableWidgetItem("河南")
tablewidget.setItem(1, 2, jgItem2)
# 禁止编辑
tablewidget.setEditTriggers(QAbstractItemView.NoEditTriggers)
# 整行选择
tablewidget.setSelectionBehavior(QAbstractItemView.SelectRows)
# 调整列和行的大小
tablewidget.horizontalHeader().setSectionResizeMode(QHeaderView.Stretch)
tablewidget.verticalHeader().setSectionResizeMode(QHeaderView.Stretch)
# 设置水平竖直表头是否显示
# tablewidget.horizontalHeader().setVisible(False)
# tablewidget.verticalHeader().setVisible(False)
# 设置竖直表头标题，五特殊要求可以不用设置
# tablewidget.setVerticalHeaderLabels(["a","b"])
# 隐藏表格线，False隐藏
tablewidget.setShowGrid(False)
self.scrollBar = tablewidget.verticalScrollBar()
self.scrollBar.valueChanged.connect(self.verticalScrollBarChanged)
# self.scrollBar.setValue(200)
# --------------------------
tablewidget2 = QTableWidget()
tablewidget2.setRowCount(44)
tablewidget2.setColumnCount(3)
tablewidget2.setHorizontalHeaderLabels(['姓名', '年龄', '籍贯'])
nameItem1 = QTableWidgetItem("张飞")
tablewidget2.setItem(0, 0, nameItem1)
ageItem1 = QTableWidgetItem("24")
tablewidget2.setItem(0, 1, ageItem1)
jgItem1 = QTableWidgetItem("河北")
tablewidget2.setItem(0, 2, jgItem1)
nameItem2 = QTableWidgetItem("关羽")
tablewidget2.setItem(1, 0, nameItem2)
ageItem2 = QTableWidgetItem("25")
tablewidget2.setItem(1, 1, ageItem2)
jgItem2 = QTableWidgetItem("河南")
tablewidget2.setItem(1, 2, jgItem2)
# 禁止编辑
tablewidget2.setEditTriggers(QAbstractItemView.NoEditTriggers)
# 整行选择
tablewidget2.setSelectionBehavior(QAbstractItemView.SelectRows)
# 调整列和行的大小
tablewidget2.horizontalHeader().setSectionResizeMode(QHeaderView.Stretch)
tablewidget2.verticalHeader().setSectionResizeMode(QHeaderView.Stretch)
# 设置水平竖直表头是否显示
# tablewidget.horizontalHeader().setVisible(False)
# tablewidget.verticalHeader().setVisible(False)
# 设置竖直表头标题，五特殊要求可以不用设置
# tablewidget.setVerticalHeaderLabels(["a","b"])
# 隐藏表格线，False隐藏
tablewidget2.setShowGrid(False)
self.scrollBar2 = tablewidget2.verticalScrollBar()
self.scrollBar2.valueChanged.connect(self.verticalScrollBarChanged)
# self.scrollBar.setValue(200)
layout.addWidget(tablewidget)
layout.addWidget(tablewidget2)
self.setLayout(layout)
def verticalScrollBarChanged(self, e):
self.scrollBar.setValue(e)
self.scrollBar2.setValue(e)
if __name__ == '__main__':
app = QApplication(sys.argv)
example = TableWidgetDemo()
example.show()
sys.exit(app.exec_())
关键在于监听到滚动条的变化，将滚动距离同时设置给其他TableWidget
tablewidget2.verticalScrollBar()
可以拿到tablewidget的滚动条
self.scrollBar2.valueChanged.connect(self.verticalScrollBarChanged)
将变化事件绑定到handleTextChanged方法
self.scrollBar.setValue(e)
方法里面再setValue(e)赋值
之后再将其他的滚动条隐藏优化就可以了
