I'm learning PySide6 and I'm trying to create a frameless QInputDialog.
When I set:
from PySide6.QtCore import Qt
from PySide6.QtWidgets import QApplication, QInputDialog, QMainWindow
app = QApplication()
input_dialog = QInputDialog(flags=Qt.FramelessWindowHint)
text, ok = input_dialog.getText(QMainWindow(), 'input dialog', 'Is this ok?')
if ok:
print(text)
app.exec()
the frame still appears. Why?
The getText method is static so input_dialog is not the displayed window but an instance of QInputDialog is created internally, so you must pass the flags through the method:
from PySide6.QtCore import Qt
from PySide6.QtWidgets import QApplication, QInputDialog
app = QApplication()
text, ok = QInputDialog.getText(
None, "input dialog", "Is this ok?", flags=Qt.FramelessWindowHint
)
if ok:
print(text)

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?
I wanted to create a browsing media file with QT so I wrote that :
import sys
import random
import os
import time
from PyQt6 import QtCore, QtWidgets, QtGui
from PyQt6.QtWidgets import QLabel, QPushButton,QSizePolicy, QFileDialog,QHBoxLayout, QVBoxLayout, QSlider, QInputDialog, QMainWindow, QApplication
from PyQt6.QtGui import QPixmap, QShortcut, QKeySequence, QMovie
from PyQt6.QtCore import Qt,QUrl, QTimer, QSettings, QSize, QPoint
from PyQt6.QtMultimediaWidgets import QVideoWidget
from PyQt6.QtMultimedia import QMediaPlayer, QAudioOutput
# Subclass QMainWindow to customize your application's main window
class MainWindow(QMainWindow):
def __init__(self):
super().__init__()
self.posi = 0
#path
if (len( sys.argv ) > 1):
self.folderpath = sys.argv[1]
else:
self.folderpath = "your folder contaianing the files" #<============ DONT FORGET TO FINISH THE PATH WITH /
#pathlist
self.img_list = os.listdir(self.folderpath)
print(self.img_list)
self.setWindowTitle("My App")
self.mediaPlayer = QMediaPlayer(None)
self.videoWidget = QVideoWidget()
self.audio_output = QAudioOutput()
self.mediaPlayer.setVideoOutput(self.videoWidget)
self.mediaPlayer.setAudioOutput(self.audio_output)
self.audio_output.setVolume(50)
self.mediaPlayer.setLoops(-1)
self.mediaPlayer.setSource(QUrl(self.folderpath+self.img_list[0]))
self.mediaPlayer.play()
# Set the central widget of the Window.
self.setCentralWidget(self.videoWidget)
#shortcut
self.shortcut_right = QShortcut(QKeySequence("Right"),self)
self.shortcut_right.activated.connect(self.button_right_clicked)
def button_right_clicked(self, *args):#when navigate right
print("---->")
try:
self.img_list[self.posi+1]
except IndexError:
self.posi = 0
else:
self.posi = self.posi + 1
self.mediaPlayer.setSource(QUrl(self.folderpath+self.img_list[self.posi]))
self.mediaPlayer.play()
app = QApplication(sys.argv)
window = MainWindow()
window.show()
app.exec()
But sometimes when use the method "button_right_clicked" the program shutdown without any error or closing event. This method is used to navigate through the list of files in the source folder. I'm using only mp4 file for now.
The error comes from this line i presume : self.mediaPlayer.setSource(QUrl(self.folderpath+self.img_list[self.posi]))
Because when i try to set the same media (img_list[0]) file as source, instead of using index self.posi, it doesn't crash.
According to the documentation, it seems to be the approriate way of swapping between media.
Any idea how to solve this problem ?
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")
This is entire my code:
import sys
from PySide2.QtCore import Qt
from PySide2.QtWidgets import (
QApplication,
QHBoxLayout,
QLabel,
QMainWindow,
QPushButton,
QVBoxLayout,
QWidget,
)
class MainWindow(QMainWindow):
def __init__(self):
super().__init__()
v = QVBoxLayout()
h = QHBoxLayout()
for a in range(10):
button = QPushButton(str(a))
button.clicked.connect(lambda checked, a=a: self.button_clicked(a)) # error here
h.addWidget(button)
v.addLayout(h)
self.label = QLabel("")
v.addWidget(self.label)
w = QWidget()
w.setLayout(v)
self.setCentralWidget(w)
def button_clicked(self, n):
self.label.setText(str(n))
app = QApplication(sys.argv)
window = MainWindow()
window.show()
app.exec_()
When I run this code, I get a window like this:
Below the buttons, there is a QLabel, and I want when I click on any button, the button's label will refer to this QLabel, but I get a bunch of confusing errors in the terminal. What's wrong with my code, help me, thanks.
The clicked signal is overload so it accepts 2 signatures where it can send a bool or not. The default signature depends on the library, in this case it seems that PySide2 by default does not send the "checked" parameter, unlike PyQt5 that does.
The solution is to indicate the signature:
button.clicked[bool].connect(lambda checked, a=a: self.button_clicked(a))
I want to insert video in blue box(ui image) but I don't know how to insert video file.
My code is here.

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
