切换窗口

[PyQt5]python点击按钮实现窗⼝切换

纯代码:

新建个⼯程,下⾯新建三个⽂件:

ui_

ui_

三个⽂件内代码如下:

#⽂件代码

importui_dengluasdl

importui_zhucheaszc

etsimportQApplication,QMainWindow,QDialog

importsys

classparentWindow(QMainWindow):

def__init__(lf):

QMainWindow.__init__(lf)

_ui=_submit_ur()

_i(lf)

classchildWindow(QDialog):

def__init__(lf):

QDialog.__init__(lf)

=_MainWindow()

i(lf)

if__name__=='__main__':

app=QApplication()

window=parentWindow()

child=childWindow()

#通过toolButton将两个窗体关联

btn=__submit_ur

t()

#显⽰

()

(_())

#ui_⽂件代码

fromPyQt5importQtCore,QtGui,QtWidgets

classUi_submit_ur(object):

deftupUi(lf,Form):

ectName("Form")

(400,300)

=(Form)

metry((140,120,101,71))

ectName("label")

_submit_ur=utton(Form)

_submit_metry((130,190,93,28))

_submit_ectName("Ui_submit_ur")

slateUi(Form)

tSlotsByName(Form)

defretranslateUi(lf,Form):

_translate=ate

dowTitle(_translate("Form","Form"))

t(_translate("Form","我是登陆"))

_submit_t(_translate("Form","注册页⾯"))

#ui_⽂件代码

fromPyQt5importQtCore,QtGui,QtWidgets

classUi_MainWindow(object):

deftupUi(lf,Form):

ectName("Form")

(400,300)

=(Form)

metry((150,170,72,15))

ectName("label")

slateUi(Form)

tSlotsByName(Form)

defretranslateUi(lf,Form):

_translate=ate

dowTitle(_translate("Form","Form"))

t(_translate("Form","我是注册"))

运⾏.出现主界⾯,点击按钮,出现第⼆个窗⼝

设计界⾯操作

打开QTDesigner设计两个如图所⽰的界⾯

类别可

以到后⾯改

再pycharm中重构它,把.ui⽂件变成.py⽂件

ui_denglu⽂件中,把class改为Ui_submit_ur

ui_zhuce同理,改为Ui_MainWindow

要注意这⾥的按钮名称要⼀致

运⾏即可
