python中pyqt5树节点点击如何实现多窗口切换问题-创新互联
这篇文章主要介绍python中pyqt5树节点点击如何实现多窗口切换问题，文中介绍的非常详细，具有一定的参考价值，感兴趣的小伙伴们一定要看完！
具体代码如下所示：
# coding=utf-8
import sys
from PyQt5.QtWidgets import *
from PyQt5.QtCore import *
from PyQt5.QtGui import *
class Example(QWidget):
def __init__(self):
super().__init__()
self.initUI()
def initUI(self):
hbox = QHBoxLayout(self)
left = QFrame(self)
# QFrame 控件添加StyledPanel样式能使QFrame 控件之间的界限更加明显
#left.setFrameShape(QFrame.StyledPanel)
right = QFrame(self)
#right.setFrameShape(QFrame.StyledPanel)
splitter1 = QSplitter(Qt.Horizontal)
splitter1.addWidget(left)
splitter1.setSizes([20,]) #设置分隔条位置
splitter1.addWidget(right)
hbox.addWidget(splitter1)
self.setLayout(hbox)
# 树
self.tree = QTreeWidget(left)
self.tree.setStyleSheet("background-color:#eeeeee;border:outset;color:#215b63;")
self.tree.setAutoScroll(True)
self.tree.setEditTriggers(QAbstractItemView.DoubleClicked | QAbstractItemView.EditKeyPressed)
self.tree.setTextElideMode(Qt.ElideMiddle)
#self.tree.setIndentation(30)
self.tree.setRootIsDecorated(True)
self.tree.setUniformRowHeights(False)
self.tree.setItemsExpandable(True)
self.tree.setAnimated(False)
self.tree.setHeaderHidden(True)
self.tree.setExpandsOnDoubleClick(True)
self.tree.setObjectName("tree")
# 设置根节点
root = QTreeWidgetItem(self.tree)
root.setText(0, '系统管理')
# 设置树形控件的列的宽度
#self.tree.setColumnWidth(0, 150)
# 设置子节点1
child1 = QTreeWidgetItem()
child1.setText(0, '增加人员信息')
root.addChild(child1)
# 设置子节点2
child2 = QTreeWidgetItem(root)
child2.setText(0, '查询人员信息')
# 加载根节点的所有属性与子控件
self.tree.addTopLevelItem(root)
# 设置stackedWidget
self.stackedWidget = QStackedWidget(right)
# 设置第一个面板
self.form1 = QWidget()
self.formLayout1 = QHBoxLayout(self.form1)
self.label1 = QLabel()
self.label1.setText("增加人员信息面板")
self.label1.setSizePolicy(QSizePolicy(QSizePolicy.Expanding, QSizePolicy.Expanding))
self.label1.setAlignment(Qt.AlignCenter)
self.label1.setFont(QFont("Roman times", 50, QFont.Bold))
self.formLayout1.addWidget(self.label1)
# 设置第二个面板
self.form2 = QWidget()
self.formLayout2 = QHBoxLayout(self.form2)
self.label2 = QLabel()
self.label2.setText("查询人员信息面板")
self.label2.setSizePolicy(QSizePolicy(QSizePolicy.Expanding, QSizePolicy.Expanding))
self.label2.setAlignment(Qt.AlignCenter)
self.label2.setFont(QFont("Roman times", 50, QFont.Bold))
self.formLayout2.addWidget(self.label2)
# 将两个面板，加入stackedWidget
self.stackedWidget.addWidget(self.form1)
self.stackedWidget.addWidget(self.form2)
# 树节点监听事件
self.tree.clicked.connect(self.onClicked)
# 窗口大化
self.showMaximized()
self.setWindowTitle('树窗口分隔案列')
self.show()
def onClicked(self,qmodeLindex):
item=self.tree.currentItem()
print('Key=%s,value=%s'%(item.text(0),item.text(1)))
if item.text(0) == '增加人员信息':
self.on_pushButton1_clicked()
elif item.text(0) == '查询人员信息':
self.on_pushButton2_clicked()
else:
print('返回主界面')
# 按钮一：打开第一个面板
def on_pushButton1_clicked(self):
self.stackedWidget.setCurrentIndex(0)
# 按钮二：打开第二个面板
def on_pushButton2_clicked(self):
self.stackedWidget.setCurrentIndex(1)
if __name__ == '__main__':
app = QApplication(sys.argv)
ex = Example()
sys.exit(app.exec_())ps：下面给大家介绍下python pyqt5 点击按钮来打开另一个窗口
import ui_denglu as dl import ui_zhuche as zc from PyQt5.QtWidgets import QApplication,QMainWindow,QDialog import sys class parentWindow(QMainWindow): def __init__(self): QMainWindow.__init__(self) self.main_ui = dl.Ui_submit_user() self.main_ui.setupUi(self) class childWindow(QDialog): def __init__(self): QDialog.__init__(self) self.child=zc.Ui_MainWindow() self.child.setupUi(self) if __name__=='__main__': app=QApplication(sys.argv) window=parentWindow() child=childWindow() #通过toolButton将两个窗体关联 btn=window.main_ui.pushButton_new btn.clicked.connect(child.show) # 显示 window.show() sys.exit(app.exec_())
