問題描述

我有這個(gè)我還不能解決的任務(wù).使用 PyQt 和 Qt Creator.

我想將在 QT Creator 中創(chuàng)建的自定義小部件嵌入到另一個(gè) QMainWindow 中.

1) 我做的步驟:

在 QT creator 中創(chuàng)建一個(gè) Widget 文件:

2) 將其保存為 *.ui 并應(yīng)用此行將其轉(zhuǎn)換為 *.py 文件:

pyuic5 gen_settings.ui -o gen_settings.py

3) 打開它，看到它以

從 PyQt5 導(dǎo)入 QtCore、QtGui、QtWidgets類 Ui_gen_settings(對(duì)象):def setupUi(self, gen_settings):gen_settings.setObjectName("gen_settings")

4) 當(dāng)然會(huì)導(dǎo)致函數(shù)調(diào)用:

TypeError:參數(shù)不匹配任何重載調(diào)用:addWidget(self, QWidget): 參數(shù) 1 具有意外類型函數(shù)"

當(dāng)我在另一個(gè) QMainWindow 文件中調(diào)用它時(shí):

類 Ui_MainWindow(object):def setupUi(self, MainWindow, My_Custom_widget):MainWindow.setObjectName("MainWindow")self.gridLayout.addWidget(My_Custom_widget, 1, 4, 1, 1)

任何想法如何解決它?

首先我推薦你閱讀

圖片中，Widget容器是左上角的，現(xiàn)在我們將其替換為Gen_Settings，所以我們必須

1. 將出現(xiàn)以下對(duì)話框并填寫如圖所示的字段(我假設(shè) gen_settings_ui.py 和 gen_settings.py 與當(dāng)前 .ui 位于同一文件夾中)

1. 您按下添加按鈕，然后按下升級(jí)按鈕.

<小時(shí)>

然后你用 pyuic 將 .ui 轉(zhuǎn)換為 .py ，你會(huì)得到以下結(jié)果:

從 PyQt5 導(dǎo)入 QtCore、QtGui、QtWidgets類 Ui_MainWindow(對(duì)象):def setupUi(self, MainWindow):MainWindow.setObjectName("MainWindow")# ...self.widget = Gen_Settings(self.centralwidget)self.widget.setObjectName("widget")self.gridLayout.addWidget(self.widget, 0, 0, 1, 1)# ...從 gen_settings 導(dǎo)入 Gen_Settings

I have this task that I couldn't solve yet. Working with PyQt and Qt Creator.

I want to embed a custom created widget created in QT Creator into another QMainWindow.

1) Steps I do:

Create a Widget file in QT creator:

2) Save it as *.ui and apply this line to convert it to a *.py file:

pyuic5 gen_settings.ui -o gen_settings.py

3) Open it and see that it starts with

from PyQt5 import QtCore, QtGui, QtWidgets

class Ui_gen_settings(object):
    def setupUi(self, gen_settings):
        gen_settings.setObjectName("gen_settings")

4) Which results in function call of course:

TypeError: arguments did not match any overloaded call:
  addWidget(self, QWidget): argument 1 has unexpected type 'function'

when I call it in another QMainWindow file:

class Ui_MainWindow(object):
    def setupUi(self, MainWindow, My_Custom_widget):
        MainWindow.setObjectName("MainWindow")
        self.gridLayout.addWidget(My_Custom_widget, 1, 4, 1, 1)

Any ideas how to solve it?

First of all I recommend you read the PyQt docs referring to Qt Designer.

Going to the problem, Qt Designer does not provide a widget but a class that serves as an interface to a widget, and that can be seen in his statement:

class Ui_gen_settings(object):
    # ...

The class inherits from object and not from QWidget, QDialog, QMainWindow, etc.

In the docs that indicate initially it is recommended to create a widget and use the interface provided by Qt Designer. For this it is correct to use pyuic but I will change the gen_settings.py to gen_settings_ui.py so that the change is understood.

pyuic5 gen_settings.ui -o gen_settings_ui.py

So now we create a file called gen_settings.py that contains the widget and use the interface.

gen_settings.py

from gen_settings_ui import Ui_gen_settings
from PyQt5 import QtWidgets


class Gen_Settings(QtWidgets.QWidget, Ui_gen_settings):
    def __init__(self, parent=None):
        super(Gen_Settings, self).__init__(parent)
        self.setupUi(self)

Then when you create the .ui corresponding to Ui_MainWindow you add a QWidget that is an empty container.

In the image, the Widget container is the one in the upper left, and now we will replace it with Gen_Settings, so we must promote it using the following procedure:

1. Right click on the widget container and select the Promote To ... option.

2. The following Dialog will appear and fill in the fields as shown in the image (I'm assuming that gen_settings_ui.py and gen_settings.py are in the same folder as the current .ui)

3. You press the Add button and then the Promote button.

Then you convert the .ui to .py with pyuic and you will get the following:

from PyQt5 import QtCore, QtGui, QtWidgets

class Ui_MainWindow(object):
    def setupUi(self, MainWindow):
        MainWindow.setObjectName("MainWindow")
        # ...
        self.widget = Gen_Settings(self.centralwidget)
        self.widget.setObjectName("widget")
        self.gridLayout.addWidget(self.widget, 0, 0, 1, 1)
        # ...

from gen_settings import Gen_Settings
