Thank you for reading my question.
Qt Designer does not show all the Qt widget, and often we want to add our own widget through Qt, for that there are at least 2 solutions, the first is to create a plugin and load it to Qt Designer, and the other is simpler. promote the widget, the latter is what I will show in this answer.
For this you must make certain minimum changes, I do not know what type of widget is the one you use in the blue box but you must change it to the Widget type that is in the sub-menu of the containers as shown in the following image:
after them you must right click on the widget and select Promote to ..., then a dialogue will appear, in the part of Promoted class name you must place QVideoWidget, and in the part of Header File you must place PyQt5.QtMultimediaWidgets, then press the add button and then Promote:
After that you will be able to use QVideoWidget within your application.
In the following link there is an example
Answer from here was clearer to me:
QWebKit was removed in Qt 5.6. So QWebView is no longer available. Use QWebEngineView as a replacement. In Qt Designer, just add a QWidget to your form and promote it to QWebEngineView (base class: QWidget, header: QWebEngineView). Don't forget to add webenginewidgets to your project file.
Simlar issue: want add QWebEngineView into Qt Designer
for later PySide6 to import and use .ui, exported by Qt Designer
Solution: add QWidget then Promoted to QWebEngineView
Steps
drag a new QWidget into your main ui (window)
right click QWidget -> Promoted to
new popup window, input
Base class Name: QWidget
Promoted class Name: QWebEngineView
Header File: PySide6.QtWebEngineWidgets
== parent class
Global Include: not selected
-> Screenshot
click: Add
click: Promote

I was just creating my window in the Qt Designer, when I had finished it I noticed that even opening it from a .py file, the maximize and restore buttons in the title bar are disabled, they appear in there but I can't click it. I am using Windows 10 by the way. It appears like this:
enter image description here
I found some solutions using:
self.setWindowFlag(Qt.WindowMaximizeButtonHint) self.setWindowFlag(Qt.WindowMinimizeButtonHint)
but they don't work in my case.
Here's the complete code:
from PyQt5 import QtWidgets, uic
from PyQt5.QtWidgets import *
from PyQt5.QtGui import *
from PyQt5.QtCore import *
from PyQt5.QtMultimedia import *
import sys
class mainWindow(QtWidgets.QMainWindow):
def __init__(self):
super(mainWindow, self).__init__()
uic.loadUi('mainMenu.ui', self)
self.show()
self.setWindowFlag(Qt.WindowMaximizeButtonHint)
self.setWindowFlag(Qt.WindowMinimizeButtonHint)
app = QtWidgets.QApplication(sys.argv)
window = mainWindow()
app.exec_()
I'm creating a basic pyqt6 application using the QMainWindow Class.
My code is basic. I create a basic window, but whenever I execute this code, I do not see any menu:
from PyQt6.QtWidgets import QStatusBar, QApplication, QWidget, QMainWindow, QVBoxLayout, QScrollBar, \
QToolButton
import sys
# There are THREE different window type classes
# that we can choose from:
# QWidget, QMainWindow, QDialog
class Window(QMainWindow):
def __init__(self):
super().__init__()
# Manages GUI Applications Control Flow
# and main settings..
app = QApplication([])
window = Window()
window.setWindowTitle("My 1st App")
window.statusBar().showMessage("Status Bar Message")
window.menuBar().addMenu("Menu 1")
window.show()
sys.exit(app.exec())
What am I doing wrong?
Why isn't "MENU 1" showing in the GUI?
im working on a desktop application (im a begginer) using Qt designer and Python and i need some help. When i add some pictures (images, background images) on Qt, i don't find them on my window on python after conversion.
Window on Qt designer
Window on python
.
And here is the python code.
import sys
from PyQt5.QtGui import QPixmap
from PyQt5.uic import loadUi
from PyQt5 import QtWidgets
from PyQt5.QtWidgets import QDialog, QApplication, QWidget, QStackedWidget
class WelcomeScreen(QDialog):
def __init__(self):
super(WelcomeScreen, self).__init__()
loadUi("Welcome.ui",self)
app = QApplication(sys.argv)
welcome = WelcomeScreen()
widget = QtWidgets.QStackedWidget()
widget.addWidget(welcome)
widget.setFixedWidth(932)
widget.setFixedHeight(562)
widget.show()
try:
sys.exit(app.exec())
except:
print("Exiting")
I have a page set up in PYQT5 Designer, when opened normally on the screen it looks god so I tried to save to PDF.
from PyQt5 import QtCore, QtWidgets, QtGui
from PyQt5.QtWidgets import QApplication, QFileDialog, QWidget, QMainWindow, QComboBox,
from PyQt5.QtPrintSupport import QPrinter
from export_pdf_ui import *
import sys
class MainWindow(QMainWindow):
def __init__(self, *args, **kwargs):
super(MainWindow, self).__init__(*args,**kwargs)
self.ui = Ui_MainWindow()
self.ui.setupUi(self)
self.export()
def export(self):
printer = QPrinter(QPrinter.HighResolution)
printer.setOutputFormat(QPrinter.PdfFormat)
printer.setOutputFileName("test.pdf")
printer.setPaperSize(QPrinter.A4)
printer.setPageSize(QPrinter.A4)
printer.setFullPage(True)
self.ui.centralwidget.render(printer)
app = QApplication(sys.argv)
window = MainWindow()
window.show()
app.exec_()
It works fine and outputs a PDF file, but the content is tiny and in the corner and you can't really read it even when fully zoomed in. How do I make it fill the whole page? or is it a design issue? it looks good on the screen
Try creating the printer with QPrinter::ScreenResolution rather than QPrinter.HighResolution.
I had a similar problem printing a QTextDocument to a physical printer which I created with QPrinter::HighResolution. If I called QTextDocument::setPageSize to eliminate page numbers, the output on paper would be about 50mm wide. I don't know if you are running into the same issue, but for me, the final piece of my puzzle was the resolution I created the QPrinter object with.
I am trying to create a GUI for my python program. One of the tools that I need is a text input box.
Now, I want a text label for this box saying "Please insert texts." Is there a function to add a label that shows inside the input textbox as default and disappear when user click the box to type?
I don't mind to use qt designer or pyqt5 coding.
Thank you guys.
placeholderText : QString
This property holds the line edit's placeholder text
import sys
from PyQt5.QtWidgets import QLineEdit, QVBoxLayout, QApplication, QWidget
class Test(QWidget):
def __init__(self):
super().__init__()
self.lineEdit = QLineEdit(placeholderText="Please insert texts.") # <---
vbox = QVBoxLayout(self)
vbox.addWidget(self.lineEdit)
if __name__ == '__main__':
app = QApplication(sys.argv)
w = Test()
w.show()
sys.exit(app.exec_())
I am begginer like you and my English is not so good. But I recommend you use Qt Designer. It's easier, fastter for you draw your app. I am using pyside2 project and recommend you read docummentatio each widgets you wanna use in PySide2 project and Qt Project. Try code below
enter image description here
import sys
from PySide2.QtWidgets import QApplication
from PySide2.QtWidgets import QDialog
from PySide2.QtWidgets import QTextEdit
from PySide2.QtWidgets import QVBoxLayout
from PySide2.QtCore import Qt
class MainDialog(QDialog):
def __init__(self, parent=None):
super(MainDialog, self).__init__(parent)
# Create Widget TextEdit
self.text = QTextEdit()
# I think that you wanna this function in your program
# https://doc.qt.io/qtforpython/PySide2/QtWidgets/QLineEdit.html?highlight=qlineedit#PySide2.QtWidgets.PySide2.QtWidgets.QLineEdit.setPlaceholderText
# http://doc.qt.io/qt-5/qlineedit.html#placeholderText-prop
self.text.setPlaceholderText('''Yes! this is exactly what I want!
Thank you, what if you have a big text box (more than 10 lines) and
you want to scale up the place holder and align it in center?? ''')
# https://doc.qt.io/qtforpython/PySide2/QtWidgets/QLineEdit.html?highlight=qlineedit#PySide2.QtWidgets.PySide2.QtWidgets.QLineEdit.setAlignment
# http://doc.qt.io/qt-5/qlineedit.html#alignment-prop
self.text.setAlignment(Qt.AlignCenter)
# Layout
layout = QVBoxLayout()
layout.addWidget(self.text)
self.setLayout(layout)
def main():
app = QApplication()
mainDialog = MainDialog()
mainDialog.show()
sys.exit(app.exec_())
if __name__ == '__main__':
main()
