如何在PyQT中放置動態創建的小部件

Question

我正在使用PyQGIS根據圖層中字段名稱的數量動態創建窗口小部件。 窗口小部件已成功創建，但是放置不正確。 有沒有辦法使用Python將lineedit框放置在中間？下面是我用於動態創建小部件的代碼。

selectedLayerIndex = self.dlg.comboBox.currentIndex()
selectedLayer = layers[selectedLayerIndex]
fields = selectedLayer.pendingFields()
fieldnames = [field.name() for field in fields]
for i,field in enumerate(fieldnames):
    self.labels = QLabel()
    self.linedit = QLineEdit()
    self.labels.setText(field)
    self.linedit.setFixedWidth(100)
    self.dlg.verticalLayout.addWidget(self.labels)
    self.dlg.verticalLayout.addWidget(self.linedit)

我希望在文本框中放置這樣的內容

如果要獲得表單的相同順序，則必須使用QFormLayout 。

selectedLayerIndex = self.dlg.comboBox.currentIndex()
selectedLayer = layers[selectedLayerIndex]
fields = selectedLayer.pendingFields()
fieldnames = [field.name() for field in fields]
flay = QFormLayout()
for field in fieldnames:
    le = QLineEdit()
    le.setFixedWidth(100)
    flay.addRow(field, le)
self.dlg.verticalLayout.addLayout(flay)
