在布局中移动小部件 pyqt

Question

你好我的代码中有按钮我希望当用户按下插入新按钮时它会将所有其他按钮移动到下面一行并在按下的按钮下方创建一个新按钮这是我的代码

基本上我试图将布局中的所有按钮移动到下方一行，然后添加新按钮：

def Insert_Stage(self) :
    button = self.sender()
    idx = self.Layout.indexOf(button)
    location = self.Layout.getItemPosition(idx)

    x=location[0]
    z=self.Layout.rowCount()
    print(x,z)
    while(z >x+1):

        items= self.Layout.itemAt(z)
        # setting the item as widget 
        widget=items.widget()
        index= self.Layout.indexOf(widget)
        loc=self.Layout.getItemPosition(index)

        d=loc[0]
        y=loc[1]
        if y!=0:
            #widget.move(d+100,d)
            self.Layout.addWidget(widget,(d+1),1)
        else:
         self.Layout.addWidget(widget,d+1,0)
        z-=1

    stage=QtGui.QPushButton(self)
    stage.setObjectName(button.objectName())
    k=(int(button.objectName()[5:])+1)
    stage.setText('stage%d'%k)
    self.Layout.addWidget(stage,(location[0]+1),0)

假设您使用的是 QVBoxLayout 您必须使用 insertWidget() 方法：

from PyQt4 import QtCore, QtGui

class Widget(QtGui.QLineEdit):
    def __init__(self, parent=None):
        super(Widget, self).__init__(parent)
        lay = QtGui.QVBoxLayout(self)
        for i in range(5):
            btn = QtGui.QPushButton(
                'button {}'.format(i),
                clicked=self.on_clicked
            )
            lay.addWidget(btn)

    @QtCore.pyqtSlot()
    def on_clicked(self):
        btn = self.sender()
        ix = self.layout().indexOf(btn)
        new_btn = QtGui.QPushButton(
            "button {}".format(self.layout().count()),
            clicked=self.on_clicked
        )
        self.layout().insertWidget(ix+1, new_btn)

if __name__ == '__main__':
    import sys

    app = QtGui.QApplication.instance()
    if app is None:
        app = QtGui.QApplication(sys.argv)
    w = Widget()
    w.show()
    sys.exit(app.exec_())
