PyQt - 无法向树子级添加按钮

Question

我创建了一个应该如下所示的树视图：

parent1
    path branch [button]
    path branch [button]
    ...

我像这样创建树

def create_tree(self,containerWidget):
  self.repo_tree = QTreeView(self)
  self.repo_tree.setGeometry(10, 10, 580, 380)

  self.repo_tree_model = QStandardItemModel()
  self.repo_tree.setModel(self.repo_tree_model)

  containerWidget.addWidget(self.repo_tree)

我像这样添加父母和孩子

def add_tree_repo(self,repo_url, repo_name, branch, repo_path,config,worktrees):
  root_item = QStandardItem(repo_name)
  self.repo_tree_model.appendRow(root_item)

  for worktree in worktrees:
     child1 = QStandardItem(worktree["path"])
     child2 = QStandardItem("[" + worktree["branch"] + "]")
     root_item.appendRow([child1,child2])

     button = QToolButton()
     button.setMaximumSize(button.sizeHint())
     self.repo_tree.setIndexWidget(child2.index(), button)

  self.repo_tree.update()
  self.repo_tree.expandAll()

仅显示路径：

parent1
    path
    path
    ...

我错过了什么？任何帮助表示赞赏

Answer 1

显然这解决了问题

self.repo_tree_model.setHorizontalHeaderLabels(["Column 1", "Column 2", "Column 3"])
