我有两个.ui
文件,我用pyuic转换为python文件。我现在要做的是从另一个开放。
主窗口代码:

import sys
app = QtGui.QApplication(sys.argv)
Dialog = QtGui.QDialog()
ui = Ui_Dialog()
ui.setupUi(Dialog)
Dialog.show()
sys.exit(app.exec_())
我的猜测是,我将不得不导入其他文件并调用一些方法来显示它。有没有办法这样做:
secondWindow = Ui_Dialog
secondWindow.show()
或沿着这些方向的东西?我尝试了类似的东西,但它说没有方法show()。这是因为班级的构建方式吗?
我甚至尝试过这样的事情:
def nom():
import sys
app = QtGui.QApplication(sys.argv)
Dialog = QtGui.QDialog()
ui = Ui_Dialog()
ui.setupUi(Dialog)
Dialog.show()
sys.exit(app.exec_())
我的想法是,如果if __name__=="main":
下的代码在启动时执行,为什么我不能把它放到另一个函数中。
答案 0 :(得分:1)
一个简单的工作示例是:
import sys
from PyQt4 import QtGui
from mainwindow import Ui_MainWindow
from dialog import Ui_Dialog
class MainWindow(QtGui.QMainWindow, Ui_MainWindow):
def __init__(self):
QtGui.QMainWindow.__init__(self)
self.setupUi(self)
self.pushButton.clicked.connect(self.show_dialog)
def show_dialog(self):
dialog = Dialog()
ret = dialog.exec_()
if ret == QtGui.QDialog.Accepted:
self.textEdit.append('accepted')
else:
self.textEdit.append('rejected')
class Dialog(QtGui.QDialog, Ui_Dialog):
def __init__(self):
QtGui.QMainWindow.__init__(self)
self.setupUi(self)
if __name__ == '__main__':
app = QtGui.QApplication(sys.argv)
mw = MainWindow()
mw.show()
sys.exit(app.exec_())
如果您为第一个文件mainwindow.py
和第二个文件dialog.py
命名,则此功能正常。
第一个类继承自Ui_MainWindow
,另一个继承自Ui_Dialog
,因此他们从导入的文件中获取代码。然后他们调用setupUi(self)
“生成”窗口。
在if __name__ ...
内容的底部,它实例化了两个类,然后show()
将起作用并显示窗口。
如果使用pyuic生成代码然后更改代码,如果修改.ui
- 文件并重新生成python代码,它将被简单地覆盖!因此,您应该始终创建一个“主”文件并将GUI导入其中。
代码仅在您从第一个文件中删除from hi import Ui_Dialog
和def open(self):
时才有效
你自己的函数,比如open
(因为内置open
而应该得到另一个名字)应该进入主文件!
编辑:更改了代码,以便在点击“PhusButton”时显示对话框。
要“启动”对话框,您需要使用exec_
方法。在上面的代码中,来自按钮的clicked
信号连接到show_dialog
方法。每次单击按钮后都会调用此方法。然后,如果使用 ok 或取消关闭对话框,它将执行对话框并写入文本字段。
