一、QListWidget
# 创建一个QListWidget对象：
listWidget = QListWidget()
# 创建并添加列表项：
item1 = QListWidgetItem("Item 1")
item2 = QListWidgetItem("Item 2")
listWidget.addItem(item1)
listWidget.addItem(item2)
# 在需要的地方显示QListWidget部件：
listWidget.show()
方法解析
listWidget.clearSelection() # 清除所有的选择
item = listWidget.item(0)
item.setSelected(True) # 设置列表项的选中状态
selectedItems = listWidget.selectedItems() # 获取当前选择的列表项
for item in selectedItems:
print(item. Text())
# 设置多重选择模式
self.Settings_UI.listWidget.setSelectionMode(QAbstractItemView.MultiSelection)
# 处理多重选择事件
self.Settings_UI.listWidget.itemSelectionChanged.connect(self.handleSelectionChanged)
def handleSelectionChanged(self):
items = [] # 列表
selectedItems = self.Settings_UI.listWidget.selectedItems()
for item in selectedItems:
# print(item.text())
items.append(item.text() + ' ') # 选中的值添加到列表
# print(items)
select_data = "".join(items)
print(select_data) # 列表转 str类型输出
self.Settings_UI.lineEdit_18.setText(select_data) # 将选择的结果生成在LineEdit里
result1_data = self.Settings_UI.lineEdit_18.text() # 获取LineEdit数据
示例代码
from PySide6.QtWidgets import QApplication, QMainWindow, QListWidget, QListWidgetItem, QAbstractItemView
def handleSelectionChanged():
selectedItems = listWidget.selectedItems()
for item in selectedItems:
print(item.text())
app = QApplication([])
window = QMainWindow()
listWidget = QListWidget()
item1 = QListWidgetItem("Item 1")
item2 = QListWidgetItem("Item 2")
listWidget.addItem(item1)
listWidget.addItem(item2)
listWidget.setSelectionMode(QAbstractItemView.MultiSelection)
listWidget.itemSelectionChanged.connect(handleSelectionChanged)
window.setCentralWidget(listWidget)
window.show()
app.exec()
二、QListWidget 复选框
参考：https://www.cnblogs.com/itwangqiang/articles/14959367.html
| 方法 | 说明 |
|---|---|
| setChecked() | 调整复选框的状态，设置为True表示选中，False表示取消选中的复选框 |
| setText() | 设置复选框的显示文本 |
| text() | 返回复选框的显示文本 |
| self.Settings_UI.listWidget_2.setEnabled(False) | 是否启用 |
# '''按钮绑定方法'''
self.Settings_UI.checkBox_8.clicked.connect(self.ceshi)
def ceshi(self):
check_box_list = []
if self.Settings_UI.checkBox_8.isChecked():
data = self.Settings_UI.checkBox_8.text()
print(data)
check_box_list.append(data + '-') # 选中的值添加到列表
# 多个结果的话可以用列表 list
