在布局中重新排序小部件

Question

我有一个senario，我有QComboBoxes（黑色矩形）和QPushButtons（红色立方体）。我需要两个按钮始终保持在最正确的组合的两侧。

代码示例：

self.button1 QPushButton()
self.button2 = QPushButton()


def addCombo():
    # remove buttons from next to previous right most combo
    layout.removeWidget( self.button1 )
    layout.removeWidget( self.button2 )

    # add button left of new right most combo
    layout.addWidget( self.button1 )
    # add new right most combo
    layout.addWidget( QComboBox() )
    # add button right of new right most combo
    layout.addWidget( self.button2 )


def removeCombo():
    # remove buttons from next to previous right most combo
    layout.removeWidget( self.button1 )
    layout.removeWidget( self.button2 )

    # delete right most combo
    layout.takeAt( len(layout.children()) -1 )

    # add button left of new right most combo # button , index
    layout.insertWidget( self.button1 ,  len(layout.children()) - 2 )
    # add button right of new right most combo
    layout.addWidget( self.button2 )


#So for the first layout:
layout.addWidget( QComboBox() )
layout.addWidget( self.button1 ) 
layout.addWidget( QComboBox() )
layout.addWidget( self.button2 )


#second layout:
addCombo()


#third layout:
addCombo()


# fourth layout

我认为嵌套布局会对您有所帮助。不要仅使用其他按钮将组合框添加到主布局，而是将组合框添加到自己的布局中，并将该布局添加到主布局中。从内部布局添加和删除组合框应该更容易，而将其他所有内容留在原处。
