3. Combine the line edit and the label with a layout, set spacing to 0
4. Set placeholder text with QLine:setPlaceholderText

如何做-内部在QLineEdit中插入按钮.[pyqt4]"

通过在其上绘制小部件(标签，按钮甚至组合框)来基本自定义QLineEdit.然后重置边距，光标，填充和绘画事件.没有魔法！

Basically customized a QLineEdit by painting a widget(label, button or even combobox) onto it. Then reset the margin, cursor, padding and the paint event. No magics!
