How to add some items or some pixmaps to the qgraphicscene? - python

I'm trying to make a puzzle game. My thought came from the 8-puzzle problem, so now I try to use the pyqt5. My opinion is that I choose a picture from my computer and then I try to use it. But when I try to upset the picture ,it comes some trouble.So I come here and look for help
since it comes to trouble so I simplify the code that just make the picture change into pieces. And now I just try them list on the qgraphicscene firstly, but I don't known why all of them stacked in the upper left corner, I just want them list in order which looks like the original picture, what should I do?

QTextEdit clickable text

I have a log I have created with a simple [Add] text near each line which I want to be able to press and have it run a function that will know which line/text it has in this line.
I can also use QTextBrowser if needed for this.
My code:
from PyQt5 import QtCore, QtGui, QtWidgets
from PyQt5.QtCore import *
from PyQt5.QtGui import *
from PyQt5.QtWidgets import *
import sys
class Ui_MainWindow(object):
def setupUi(self, MainWindow):
MainWindow.setObjectName("MainWindow")
MainWindow.resize(401, 308)
self.centralwidget = QtWidgets.QWidget(MainWindow)
self.centralwidget.setObjectName("centralwidget")
self.chat_log = QtWidgets.QTextEdit(self.centralwidget)
self.chat_log.setGeometry(QtCore.QRect(10, 10, 381, 241))
self.chat_log.setReadOnly(True)
self.chat_log.setObjectName("chat_log")
MainWindow.setCentralWidget(self.centralwidget)
class MainFrame(QMainWindow, Ui_MainWindow):
def __init__(self, parent=None):
super(MainFrame, self).__init__(parent)
self.setupUi(self)
def appending(self):
self.chat_log.append("Somethingsomething [Add]")
self.chat_log.append("Hello[Add]")
self.chat_log.append("What is up [Add]")
self.chat_log.append("Big boy [Add]")
if __name__ == "__main__":
app = QApplication(sys.argv)
form = MainFrame()
form.show()
form.appending()
app.exec_()
What I want is basically when someone pressed "[Add]" it will know which line it pressed and will print the text in that line
Say I pressed the first line it will then print("Somethingsomething")
You need to make your [Add] texts clickable, the easiest way to do so is using HTML markup, then you just need to identify the text you had been clicking on:
from PyQt5 import QtCore, QtGui, QtWidgets
from PyQt5.QtCore import *
from PyQt5.QtGui import *
from PyQt5.QtWidgets import *
import sys
class MyTextEdit(QtWidgets.QTextEdit):
def mousePressEvent(self, e):
self.link = self.anchorAt(e.pos())
def mouseReleaseEvent(self, e):
if self.link:
print(f"Clicked on {self.link}")
self.link = None
class Ui_MainWindow(object):
def setupUi(self, MainWindow):
MainWindow.setObjectName("MainWindow")
MainWindow.resize(401, 308)
self.centralwidget = QtWidgets.QWidget(MainWindow)
self.centralwidget.setObjectName("centralwidget")
self.chat_log = MyTextEdit(self.centralwidget)
self.chat_log.setGeometry(QtCore.QRect(10, 10, 381, 241))
self.chat_log.setReadOnly(True)
self.chat_log.setObjectName("chat_log")
MainWindow.setCentralWidget(self.centralwidget)
class MainFrame(QMainWindow, Ui_MainWindow):
def __init__(self, parent=None):
super(MainFrame, self).__init__(parent)
self.setupUi(self)
def appending(self):
messages = ["Somethingsomething", "Hello", "What is up", "Big bo"]
for msg in messages:
self.chat_log.append(
f'<span>{msg}<a style="color: pink" href="{msg}">[Add]</a></span>'
)
if __name__ == "__main__":
app = QApplication(sys.argv)
form = MainFrame()
form.show()
form.appending()
app.exec_()
Out:
Clicked on Big bo
Clicked on Hello
Clicked on Somethingsomething

PyQt5 - not able to add elements to QTabWidget

I am trying to add a second tab (containing a pie chart visualization) to my PyQt5 GUI, but I cannot figure out how to display it. This second tab is laid out in a separate class and my program has the following structure:

I have been trying various solutions, but no luck so far. Any help would be highly appreciated!

Qtimer and closing out an applicaiton after 15 seconds have passed

Evening. I am having a bit of a hard time both understanding QTimer and how it works as well as getting the below code to work. As much as I hate copy/pasting, I just cannot figure it out. The goal of this is to run the program for 15 seconds and then exit out completely. Everything else works, but when I try to integrate QTimer to count how many seconds have passed, it does nothing or just simply does not work regardless of the variations I try. Below is the latest code:
from PyQt5 import QtCore, QtGui, QtWidgets
from PyQt5.QtGui import QMovie
from PyQt5.QtCore import QTimer
import winsound
import time
import sys
class Ui_MainWindow(object):
def setupUi(self, MainWindow):
MainWindow.setObjectName("MainWindow")
MainWindow.resize(321, 249)
self.centralwidget = QtWidgets.QWidget(MainWindow)
self.centralwidget.setObjectName("centralwidget")
self.label = QtWidgets.QLabel(self.centralwidget)
self.label.setGeometry(QtCore.QRect(0, 0, 320, 248))
self.label.setFrameShape(QtWidgets.QFrame.Box)
self.label.setOpenExternalLinks(False)
self.label.setTextInteractionFlags(QtCore.Qt.NoTextInteraction)
self.label.setObjectName("label")
MainWindow.setCentralWidget(self.centralwidget)
self.retranslateUi(MainWindow)
QtCore.QMetaObject.connectSlotsByName(MainWindow)
#Plays the movie in the Label
movie = QMovie("giphy.gif")
self.label.setMovie(movie)
movie.start()
#Plays the sound with the movie
winsound.PlaySound("magicwrd.wav", winsound.SND_ASYNC|winsound.SND_LOOP)
def retranslateUi(self, MainWindow):
_translate = QtCore.QCoreApplication.translate
MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow"))
#Borrowed and modified from here: https://stackoverflow.com/questions/46656634/pyqt5-qtimer-count-until-specific-seconds
#Goal is to run the application for 15 seconds and then exit out completely.
def start_timer(self, slot, count=1, interval=1000):
counter = 0
def handler():
nonlocal counter
counter += 1
slot(counter)
if counter >= count:
timer.stop()
timer.deleteLater()
timer = QtCore.QTimer()
timer.timeout.connect(handler)
timer.start(interval)
def timer_func(self, count):
if count >= 5:
sys.exit(app.exec_())
if __name__ == "__main__":
app = QtWidgets.QApplication(sys.argv)
MainWindow = QtWidgets.QMainWindow()
ui = Ui_MainWindow()
ui.setupUi(MainWindow)
MainWindow.show()
Ui_MainWindow.start_timer(Ui_MainWindow.timer_func, 5)
app.exec_()
If you want to finish the application in T seconds then you must use a QTimer::singleShot() so that when it is triggered then QCoreApplication::quit() is invoked:
QtCore.QTimer.singleShot(T * 1000, QtCore.QCoreApplication.quit)
In the example that you link, it has another objective: to print some information every T seconds and after repeating K times the application is closed, and therefore uses a complicated logic that you do not need.
Considering the above and the PyQt5 recommendation, the solution is:
import sys
import winsound
from PyQt5 import QtCore, QtGui, QtWidgets
class Ui_MainWindow(object):
def setupUi(self, MainWindow):
MainWindow.setObjectName("MainWindow")
MainWindow.resize(321, 249)
self.centralwidget = QtWidgets.QWidget(MainWindow)
self.centralwidget.setObjectName("centralwidget")
self.label = QtWidgets.QLabel(self.centralwidget)
self.label.setGeometry(QtCore.QRect(0, 0, 320, 248))
self.label.setFrameShape(QtWidgets.QFrame.Box)
self.label.setOpenExternalLinks(False)
self.label.setTextInteractionFlags(QtCore.Qt.NoTextInteraction)
self.label.setObjectName("label")
MainWindow.setCentralWidget(self.centralwidget)
self.retranslateUi(MainWindow)
QtCore.QMetaObject.connectSlotsByName(MainWindow)
def retranslateUi(self, MainWindow):
_translate = QtCore.QCoreApplication.translate
MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow"))
class MainWindow(QtWidgets.QMainWindow, Ui_MainWindow):
def __init__(self, parent=None):
super(MainWindow, self).__init__(parent)
self.setupUi(self)
# Plays the movie in the Label
movie = QtGui.QMovie("giphy.gif")
self.label.setMovie(movie)
movie.start()
# Plays the sound with the movie
winsound.PlaySound("magicwrd.wav", winsound.SND_ASYNC | winsound.SND_LOOP)
if __name__ == "__main__":
app = QtWidgets.QApplication(sys.argv)
w = MainWindow()
w.show()
QtCore.QTimer.singleShot(15 * 1000, QtCore.QCoreApplication.quit)
sys.exit(app.exec_())

How do I access outer class variables in inner class(PyQt)?

It is not a duplicate! I didn't want to make title really long, so it's short version may seem as a duplicate. The problem is a little bit bigger than in the title.
Environment: I'm trying to build painting app using PyQt5 and Qt-Designer. I've got three files in my project: main.py, slider.py, ui.py(UI from Qt-Designer generated by pyuic).
What do I need: I need to change App's brush size(self.variable) every time Slider value changes.
The problem itself: App Class inherits Ui_MainWindow Class from the file that I can't edit(it is generated every time). Ui_MainWindow sets Slider Class as its attribute. So basically Slider is App's attribute, and I need to change App's variable "canvas" while being in Slider Class.
I don't know how to access outer class variable in inner class method. Especially when I can't edit ui.py, so I could call Slider(self) instead of Slider(self.sidebar).

Window spawned from MainWindow doesn't fully close when closing

I have a main window which creates a second window when a button is pressed. I have two problems that occur but for now I will focus on the first one: I cannot get it to completely close the old window when I close it. It closes it visually but the window is still running in the background. To illustrate this I put in a counter. Below is generic code which illustrates this issue.
Here is my dialog window:
from PyQt5 import QtCore, QtGui, QtWidgets
from form_test import Ui_Form
class formTest(QtWidgets.QWidget, Ui_Form):
def __init__(self):
QtWidgets.QWidget.__init__(self)
flags = QtCore.Qt.Drawer | QtCore.Qt.WindowStaysOnTopHint
self.setWindowFlags(flags)
self.setupUi(self)
class Ui_MainWindow(object):
def setupUi(self, MainWindow):
MainWindow.setObjectName("MainWindow")
MainWindow.resize(507, 305)
self.centralwidget = QtWidgets.QWidget(MainWindow)
self.btnOpenForm = QtWidgets.QPushButton(self.centralwidget)
self.btnOpenForm.setGeometry(QtCore.QRect(170, 30, 93, 28))
self.btnCloseForm = QtWidgets.QPushButton(self.centralwidget)
self.btnCloseForm.setGeometry(QtCore.QRect(170, 160, 93, 28))
MainWindow.setCentralWidget(self.centralwidget)
self.btnOpenForm.clicked.connect(self.openClicked)
self.btnCloseForm.clicked.connect(self.closeClicked)

def retranslateUi(self, MainWindow):
_translate = QtCore.QCoreApplication.translate
MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow"))
self.btnOpenForm.setText(_translate("MainWindow", "Open Form"))
self.btnCloseForm.setText(_translate("MainWindow", "Close Form"))
def openClicked(self):
print('open')
self.popForm = formTest()
self.popForm.show()
def closeClicked(self):
print('close')
self.popForm.close()
if __name__ == "__main__":
import sys
app = QtWidgets.QApplication(sys.argv)
MainWindow = QtWidgets.QMainWindow()
ui = Ui_MainWindow()
ui.setupUi(MainWindow)
MainWindow.show()
sys.exit(app.exec_())
Here is my spawning windows code (form_test.py):
from PyQt5 import QtCore, QtGui, QtWidgets
import time, threading
class Ui_Form(object):
def setupUi(self, Form):
Form.setObjectName("Form")
Form.resize(400, 300)
self.pushButton = QtWidgets.QPushButton(Form)
self.pushButton.setGeometry(QtCore.QRect(190, 170, 93, 28))
self.pushButton.setObjectName("pushButton")
self.pushButton.clicked.connect(self.pushButtonClicked)
self.retranslateUi(Form)
QtCore.QMetaObject.connectSlotsByName(Form)
self.loopThread = threading.Thread(target = self.looping)
self.loopThread.daemon = True
self.loopThread.start()
def retranslateUi(self, Form):
_translate = QtCore.QCoreApplication.translate
Form.setWindowTitle(_translate("Form", "Form"))
self.pushButton.setText(_translate("Form", "PushButton"))
def pushButtonClicked(self):
print("clicked")
def looping(self):
count = 0
while(True):
print('looping... ' + str(count))
count = count + 1
time.sleep(1)
if __name__ == "__main__":
import sys
app = QtWidgets.QApplication(sys.argv)
Form = QtWidgets.QWidget()
ui = Ui_Form()
ui.setupUi(Form)
Form.show()
sys.exit(app.exec_())
When I close the second window it is still running in memory. When I try to open it again another one begins running and then I have two running. Is there a different window I should use which will destroy all memory when it is closed? The second issue I am having is which my actual code (not this generic code) it causes a crash when I try to launch a second time. That issue may go away with the fixing of this issue and since I am not able to share my code online I have to stay as generic as possible for now so I am hoping to solve this issue first and maybe get resolution too.
PLEASE help ... I've worked on this FAR too long!!! Thanks, in advance, for any assistance on this.
