I can't make form1 to make parent object like it needs to be.
And all content in second form align to left-top corner and i have no way to make it work fine. May be someone know what i can do with this. Thank you!
How it looks in Qt Designer:
But how it looks really:
import sys
from PyQt5 import uic
from PyQt5.QtWidgets import QMainWindow, QApplication
class MainWindow(QMainWindow):
def __init__(self):
super().__init__()
# Set up the user interface from Designer.
uic.loadUi("mw.ui", self)
uic.loadUi("form1.ui", self.mn_general)
# Connect up the buttons.
self.pushButton.clicked.connect(self.BtnClck)
self.show()
def BtnClck(self):
print('Hello StackOverflow')
if __name__ == '__main__':
app = QApplication(sys.argv)
ex = MainWindow()
sys.exit(app.exec_())

I used Qt Designer to make two .ui files, one is the Main Window of my application, and the second is a custom widget I made. My idea was to fill a listWidget on my Main application with this custom Widget to display data.
I made this code, which compiles without problem but it does not show the customWidget on the List when it runs
import sys
from PyQt5.QtWidgets import QMainWindow, QApplication, QPushButton, QWidget, QAction, QTabWidget,QVBoxLayout,QDialog
from PyQt5 import QtCore, QtGui, QtWidgets
from mainwindowReclamo import Ui_MainWindow
from widgetReclamos import Ui_Form
#Custom Widget*
class WidgetReclamo(QWidget, Ui_Form):
"""docstring for ClassName"""
def __init__(self,*args,**kwargs):
QWidget.__init__(self,*args,**kwargs)
self.setupUi(self)
print("I am Alive")
#My Main Program*
class ProgramaReclamos(QMainWindow, Ui_MainWindow):
def __init__(self,*args,**kwargs):
QMainWindow.__init__(self,*args,**kwargs)
self.setupUi(self)
#I create an Item*
Item = QtWidgets.QListWidgetItem(self.listWidget)
#I create a custom widget*
Item_Widget = WidgetReclamo()
#I set the Size from the Item to the same of the widget*
Item.setSizeHint(Item_Widget.sizeHint())
#I add it to the list*
self.listWidget.addItem(Item)
self.listWidget.setItemWidget(Item, Item_Widget)
if __name__ == '__main__':
app = QApplication(sys.argv)
prog = ProgramaReclamos()
prog.show()
sys.exit(app.exec_())
I saw some questions online wich their answer were for PyQt4 and they said something about using a Layout for the Widget, but I don´t understand if I have to make one becouse the widget was made in the .ui file
As EYLLANESC said on the comment:
Change Item.setSizeHint(Item_Widget.sizeHint()) to Item.setSizeHint(Item_Widget.size()) – eyllanesc
Thank you !
So, I'm making a QTextEdit that edits a text file. I got the loading and saving working fine with buttons. But I got the habit of pressing Ctrl+S to save every time I paste something into the textedit because I used that in Notepad before. So I've been trying to implement it. But I can't wrap my head around how to detect and execute my save function. Lets call it savetext.
I've been going around trying to get keyPressEvent to work, but I just don't understand how it works. So I've been pretty helpless in trying to learn it.
My heavily simplified code looks like this:
class GUI(QProcess):
def init etc...
"Button creations and connect to save/load function"
self.textedit=QTextEdit()
def savetext(self):
code
def loadtext(self):
code
Now, how do I detect a key combination being detected in the QTextEdit, or anywhere in my program for that matter, and cause it to do savetext? In my case, Ctrl+S, though I'd just love a general explanation so I could apply it to any combo.
Use QShortcut and QKeySequence
from PyQt5.QtWidgets import QApplication, QTextEdit, QShortcut
from PyQt5.QtGui import QKeySequence
import sys
def slot():
print("Ctrl+S")
app = QApplication(sys.argv)
textedit=QTextEdit()
shortcut = QShortcut(QKeySequence("Ctrl+S"), textedit)
shortcut.activated.connect(slot)
textedit.show()
sys.exit(app.exec_())
You can probably use QShortcut, and right now it will activate only when textedit in focus. If you want to change the behavior please take a look here
Here is a example
import sys
from PyQt4 import QtGui, QtCore
class Window(QtGui.QWidget):
def __init__(self):
QtGui.QWidget.__init__(self)
layout = QtGui.QVBoxLayout(self)
self.edit = QtGui.QTextEdit()
layout.addWidget(self.edit)
self.button = QtGui.QPushButton('Test')
layout.addWidget(self.button)
foo = QtGui.QShortcut(QtGui.QKeySequence("Ctrl+S"), self.edit, self.saveCall, context=QtCore.Qt.WidgetShortcut)
def saveCall(self):
self.edit.append('Please save me')
if __name__ == '__main__':
app = QtGui.QApplication(sys.argv)
win = Window()
win.show()
sys.exit(app.exec_())
I'm still new with python and Qt designer. I would like to develop an application where user need to press the 'pushbutton' in order to view the image(from local directory path) on GUI mainwindow.This will keep repeating until complete number of cycle.
Did tried using QLabel and QGraphiscView widget but doesn't work.(probably due to lack of knowledge). Could anyone help me to solve it?
Below is the code:
#!/usr/bin/env python
from __future__ import division
import sys
from PyQt4 import QtCore, QtGui, uic
gui_file = 'image.ui'
Ui_MainWindow, QtBaseClass = uic.loadUiType(gui_file)
class showImage(QtGui.QMainWindow,Ui_MainWindow):
def __init__(self):
QtGui.QMainWindow.__init__(self)
Ui_MainWindow.__init__(self)
self.setupUi(self)
self.get_image_button.clicked.connect(self.getImage)
def getImage(self):
image_path='c:/Users/mohd_faizal4/Desktop/Python/Image/image1.jpg' #path to image file
self.label_image.QPixmap(image_path)
if __name__ == '__main__':
app = QtGui.QApplication(sys.argv)
myWindow = showImage()
myWindow.show()
sys.exit()
app.exec_()
Really appreciate!

Question - How do I add controls to the main form or a scroll area widget on the main form (created in QT Designer) programmatically?
I have created a MainWindow in qt designer and added my widgets. The following is the entire test program in PyCharm:
import sys
from PyQt4 import QtGui, QtCore, uic
from PyQt4.QtGui import *
from PyQt4.QtCore import *
qtCreatorFile = "programLauncher.ui"
Ui_MainWindow, QtBaseClass = uic.loadUiType(qtCreatorFile)
class MyApp(QtGui.QMainWindow, Ui_MainWindow):
def __init__(self):
QtGui.QMainWindow.__init__(self)
Ui_MainWindow.__init__(self)
self.setupUi(self)
# Cannot resize or maximize
self.setFixedSize(1045, 770)
# Add button test
self.dateLabel = QtGui.QLabel("Test")
self.pushButton = QtGui.QPushButton('Test button')
# self.scrollArea_programs.addWidget()
grid = QtGui.QGridLayout()
# self.scrollArea_programs.addWidget(self.pushButton)
grid.addWidget(self.dateLabel,0,0)
grid.addWidget(self.pushButton,0,1)
self.setLayout(grid)
self.pushButton_exit.clicked.connect(self.closeEvent)
def closeEvent(self):
QtGui.QApplication.quit()
if __name__ == "__main__":
app = QtGui.QApplication(sys.argv)
window = MyApp()
window.show()
sys.exit(app.exec_())
As you can see I tried to add controls to a grid but nothing shows up when the program runs - I have also tried to add a control to the scroll area. Can someone help me to just add 1 control to the scroll area at run time - so then I can know the proper way to do it or "a" proper way to do this.
Thanks in advance
Without having access to your programLauncher.ui and making minimal changes to your posted code, you can add your UI elements to the window like so:
from PyQt4 import QtGui
import sys
class MyApp(QtGui.QMainWindow):
def __init__(self):
QtGui.QMainWindow.__init__(self)
# Cannot resize or maximize
self.setFixedSize(1045, 770)
widget = QtGui.QWidget(self)
self.setCentralWidget(widget)
# Add button test
self.dateLabel = QtGui.QLabel("Test")
self.pushButton = QtGui.QPushButton('Test button')
grid = QtGui.QGridLayout()
grid.addWidget(self.dateLabel, 0, 0)
grid.addWidget(self.pushButton, 0, 1)
widget.setLayout(grid)
self.pushButton.clicked.connect(self.closeEvent)
def closeEvent(self, event):
QtGui.QApplication.quit()
if __name__ == "__main__":
app = QtGui.QApplication(sys.argv)
window = MyApp()
window.show()
sys.exit(app.exec_())
This will get the controls on the screen, although the layout leaves a lot to be desired. You may have to make modifications to this based on what's in your .ui file. One thing that you'll want to note in this example is that the QMainWindow needs a central widget (widget in the example above). You then set the layout on that widget.
You can use the designer to create your .ui file
The you can load it in your .py using something like:
from PyQt4 import QtCore, QtGui, uic
class my_win(QtGui.QMainWindow):
def __init__(self):
self.ui = uic.loadUi('my_ui.ui',self)
then you can access all your widgets with something like
self.ui.actionQuit.triggered.connect(QtGui.qApp.quit)
or
self.ui.my_button.triggered.connect(self.do_someting)
Thanks to JCVanHamme (the programLauncher.ui hint) and also outside help I now learned most of what I need to know to access MainWindow at run time. So for anyone interested in this beginner tip:
Take a blank form in QT Designer
Add a control
Run pyuic4 batch file
Take a look at the generated .py file to learn EVERYTHING about how to add controls.
Don't let the power go to your head - cheers
I've been learning python recently and now I wanted to (try to) create my first real application, a subtitle player for Linux. So far I've been using the Greenfish subtitle player, which is aimed at Windows users and not properly working in Linux.
I wanted to create the application in qt, since I discovered that transparent windows are not possible in tkinter, but if anybody knows a better framework please suggest!
Now before starting I've been researching the web for several hours to discover how to get my application to show over a full screened flash video and it seems like this is not possible. However the aforementioned GF subtitle player manages to do so in Windows, but not in Linux(maybe it's also because it's running through wine).
So my question is it possible to create a transparent application that remains over a fullscreened flash video and if so, could you point me in the right direction?
Thanks in advance.
edit:
here some example code I've been trying. The window produced by this piece of code does not stay above a fullscreened video
import sys
from PyQt4 import QtGui, QtCore
class mymainwindow(QtGui.QMainWindow):
def __init__(self):
QtGui.QMainWindow.__init__(self, None, QtCore.Qt.WindowStaysOnTopHint)
app = QtGui.QApplication(sys.argv)
mywindow = mymainwindow()
mywindow.show()
app.exec_()
mywindow.show()
Update for PyQt5 pip install PyQt5
import sys
from PyQt5 import QtGui, QtCore, uic
from PyQt5 import QtWidgets
from PyQt5.QtWidgets import QMainWindow, QApplication
class MainWindow(QMainWindow):
def __init__(self):
QMainWindow.__init__(self)
self.setWindowFlags(
QtCore.Qt.WindowStaysOnTopHint |
QtCore.Qt.FramelessWindowHint |
QtCore.Qt.X11BypassWindowManagerHint
)
self.setGeometry(
QtWidgets.QStyle.alignedRect(
QtCore.Qt.LeftToRight, QtCore.Qt.AlignCenter,
QtCore.QSize(220, 32),
QtWidgets.qApp.desktop().availableGeometry()
))
def mousePressEvent(self, event):
QtWidgets.qApp.quit()
if __name__ == '__main__':
app = QApplication(sys.argv)
mywindow = MainWindow()
mywindow.show()
app.exec_()
The example code below will create a centred, frameless window that should stay on top of all other windows on Linux (you can click on the window to close it).
import sys
from PyQt4 import QtGui, QtCore
class mymainwindow(QtGui.QMainWindow):
def __init__(self):
QtGui.QMainWindow.__init__(self)
self.setWindowFlags(
QtCore.Qt.WindowStaysOnTopHint |
QtCore.Qt.FramelessWindowHint |
QtCore.Qt.X11BypassWindowManagerHint
)
self.setGeometry(QtGui.QStyle.alignedRect(
QtCore.Qt.LeftToRight, QtCore.Qt.AlignCenter,
QtCore.QSize(220, 32),
QtGui.qApp.desktop().availableGeometry()))
def mousePressEvent(self, event):
QtGui.qApp.quit()
app = QtGui.QApplication(sys.argv)
mywindow = mymainwindow()
mywindow.show()
app.exec_()
