i am trying to copy the text I enter into the text edit and store it into a string variable.
I have written the following code but it shows 'python has stopped working'
from PyQt5 import QtGui,QtWidgets,QtCore
import sys
class GUI(QtWidgets.QWidget):
def __init__(self):
super(GUI,self).__init__()
self.initUI()
def initUI(self):
review = QtWidgets.QLabel('Review')
reviewEdit = QtWidgets.QTextEdit()
grid = QtWidgets.QGridLayout()
grid.addWidget(review, 3, 0)
grid.addWidget(reviewEdit, 3, 1, 5, 1)
self.setLayout(grid)
self.setGeometry(300,300,350,300)
self.setWindowTitle('Sentiment Analysis')
button = QtWidgets.QPushButton("OK")
grid.addWidget(button)
button.clicked.connect(self.copyText)
self.show()
def copyText(self):
reviewEdit.setText("text")
print(text)
if __name__ == "__main__":
app = QtWidgets.QApplication(sys.argv)
GUI = GUI()
sys.exit(app.exec_())
The program stops working because of a NameError in the copyText() method. The reviewEdit variable doesn't exit in that scope, so you can't reference it.
The way to fix this is to make all the child widgets attributes of the main class - then you can access them later using self:
class GUI(QtWidgets.QWidget):
def __init__(self):
super(GUI,self).__init__()
self.initUI()
def initUI(self):
self.review = QtWidgets.QLabel('Review')
self.reviewEdit = QtWidgets.QTextEdit()
grid = QtWidgets.QGridLayout()
grid.addWidget(self.review, 3, 0)
grid.addWidget(self.reviewEdit, 3, 1, 5, 1)
self.setLayout(grid)
self.setGeometry(300,300,350,300)
self.setWindowTitle('Sentiment Analysis')
self.button = QtWidgets.QPushButton("OK")
grid.addWidget(self.button)
self.button.clicked.connect(self.copyText)
self.show()
def copyText(self):
# self.reviewEdit.setText("text")
text = self.reviewEdit.toPlainText()
print(text)
First, you should make reviewEdit a member of GUI class. Like this:
self.reviewEdit = QtGui.QTextEdit()
next, in addBold(self), you get the text like this:
text = str(self.reviewEdit.toPlainText())

So, I'm trying to create a offline desktop Pokedex using PySide6 for the GUI. The main screen is supposed to look like this:
Menu/First window opened when the program starts
And each button redirects to different contents, but I want to like "clear" this menu window, and replace its content with the content the button is supposed to show, as well as a "back" button to go back to the menu screen.
Here is my code
from PySide6.QtWidgets import QApplication, QWidget, QPushButton, QGridLayout, QLabel, QStackedLayout
class Menu(QWidget):
def __init__(self):
super().__init__()
self.setWindowTitle("Pykedex")
logoName = QLabel("Pykedex")
font = logoName.font()
font.setPointSize(30)
logoName.setFont(font)
self.stackedWidgets = QStackedLayout()
pokedex = Pokedex()
moves = Moves()
abilities = Abilities()
items = Items()
typechart = TypeChart()
tools = Tools()
self.stackedWidgets.addWidget(pokedex)
self.stackedWidgets.addWidget(moves)
self.stackedWidgets.addWidget(abilities)
self.stackedWidgets.addWidget(items)
self.stackedWidgets.addWidget(typechart)
self.stackedWidgets.addWidget(tools)
dexButton = QPushButton("Pokedex")
dexButton.clicked.connect(lambda: self.stackedWidgets.setCurrentIndex(1))
movesButton = QPushButton("Moves")
movesButton.clicked.connect(lambda: self.stackedWidgets.setCurrentIndex(2))
abilitiesButton = QPushButton("Abilities")
itemsButton = QPushButton("Items")
typechartButton = QPushButton("Type Chart")
toolsButton = QPushButton("Tools")
buttonLayout = QGridLayout(self)
buttonLayout.addWidget(logoName, 0, 0, 1, 2)
buttonLayout.addWidget(dexButton, 1, 0)
buttonLayout.addWidget(movesButton, 2, 0)
buttonLayout.addWidget(abilitiesButton, 3, 0)
buttonLayout.addWidget(itemsButton, 1, 1)
buttonLayout.addWidget(typechartButton, 2, 1)
buttonLayout.addWidget(toolsButton, 3, 1)
self.setLayout(buttonLayout)
class Pokedex(QWidget):
def __init__(self):
super().__init__()
self.setWindowTitle("Pokedex")
class Moves(QWidget):
def __init__(self):
super().__init__()
self.setWindowTitle("Moves")
class Abilities(QWidget):
def __init__(self):
super().__init__()
self.setWindowTitle("Abilities")
class Items(QWidget):
def __init__(self):
super().__init__()
self.setWindowTitle("Items")
class TypeChart(QWidget):
def __init__(self):
super().__init__()
self.setWindowTitle("Type Chart")
class Tools(QWidget):
def __init__(self):
super().__init__()
self.setWindowTitle("Tools")
if __name__ == '__main__':
import sys
app = QApplication(sys.argv)
mainWindow = Menu()
mainWindow.setFixedSize(400, 500)
mainWindow.show()
app.exec()
I tried using QStackedLayout, but couldn't make it work by any means, it justs creates an extra window.
I am trying to create a lot of rows in a PyQt5 grid widget, but they try to expand as much as they can. How can I set a fixed cell height? They are represented like this:
But I would like them to stick at the top, ordered like this:
Code:
name = QtWidgets.QLabel()
name.setText(str(ui.nombre.toPlainText()) + "({}, {}, {})".format(do, cota, alejamiento))
borrar = QtWidgets.QPushButton()
borrar.setText("X")
borrar.clicked.connect(self.borrar)
ui.elementos.addWidget(name, self.num_elementos, 0, 1, 1)
ui.elementos.addWidget(borrar, self.num_elementos, 1, 1, 1)
self.num_elementos += 1
self.update()
print(self.puntos)
And the elementos widget is created in other class:
self.scroll = QtWidgets.QScrollArea(self.gridLayoutWidget_2)
self.scroll_widget = QtWidgets.QWidget()
self.scroll_widget.resize(200, 700)
self.elementos = QtWidgets.QGridLayout()
self.scroll_widget.setLayout(self.elementos)
self.scroll.setWidget(self.scroll_widget)
self.Punto.addWidget(self.scroll, 4, 0, 1, 3)
You need to add a stretchable space beneath the rows of widgets, so that it pushes them all up to the top. One way to do this is to put another widget inside the scroll-widget, and then use a vertical layout to add the spacer. It will also help if you make the scroll-widget resizable, otherwise the rows will start to get squashed if too many are added.
Below is a demo that implements all that. Hopefully it should be clear how you can adapt this to work with your own code:
import sys
from PyQt5 import QtCore, QtWidgets
class Window(QtWidgets.QWidget):
def __init__(self):
super(Window, self).__init__()
self.scroll = QtWidgets.QScrollArea()
self.scroll.setWidgetResizable(True)
self.scroll_widget = QtWidgets.QWidget()
self.scroll_widget.setMaximumWidth(200)
self.elementos_widget = QtWidgets.QWidget()
vbox = QtWidgets.QVBoxLayout(self.scroll_widget)
vbox.setContentsMargins(0, 0, 0, 0)
vbox.addWidget(self.elementos_widget)
vbox.addStretch()
self.elementos = QtWidgets.QGridLayout()
self.elementos_widget.setLayout(self.elementos)
self.scroll.setWidget(self.scroll_widget)
self.button = QtWidgets.QPushButton('Add')
self.button.clicked.connect(self.crear_punto)
layout = QtWidgets.QVBoxLayout(self)
layout.addWidget(self.scroll)
layout.addWidget(self.button)
def crear_punto(self):
num_elementos = self.elementos.rowCount()
name = QtWidgets.QLabel()
name.setText('FOO %s' % num_elementos)
borrar = QtWidgets.QPushButton()
borrar.setText('X')
self.elementos.addWidget(name, num_elementos, 0)
self.elementos.addWidget(borrar, num_elementos, 1)
if __name__ == '__main__':
app = QtWidgets.QApplication(sys.argv)
window = Window()
window.setGeometry(500, 100, 300, 500)
window.show()
sys.exit(app.exec_())
I have a program that dynamically creates tabs with buttons on them, when the user clicks button, I want it to give me the button_id (number that corresponds to the tab index).
I understand that you can do something like tabwidget.currentIndex() to get index of tab being used, but I don't want that as I will eventually have a method that iterates through the number of tabs and access each button without selecting the tabs as shown below.
for i in range(1,self.tabWidget.count()):
self.tabWidget.widget(i).stagematch.click()
For example:
If user clicks 'Clear Text' button on 'Tab 2' then I want it to give me the number 2 back.
How can I accomplish this without using the currentIndex() method for the tabs
Test code:
import sys
from PyQt5 import QtCore, QtWidgets
class TabPage(QtWidgets.QWidget):
def __init__(self, parent=None):
super().__init__(parent)
group = QtWidgets.QGroupBox('Monty Python')
layout = QtWidgets.QVBoxLayout(self)
layout.addWidget(group)
grid = QtWidgets.QGridLayout(group)
testbutton = QtWidgets.QPushButton('Clear Text')
grid.addWidget(testbutton, 2, 2)
testbutton.clicked.connect(self.tab_match)
#testbutton.clicked.connect(self.button_id)
def button_id(self):
sender = self.sender()
print(sender.text()) # Gives text of button, i'd like a number that corresponds to the tab# that called it
def tab_match(self,button_id):
#Do something with button ID here
pass
class Window(QtWidgets.QWidget):
def __init__(self):
super().__init__()
self.tabs = QtWidgets.QTabWidget()
layout = QtWidgets.QVBoxLayout(self)
layout.addWidget(self.tabs)
button = QtWidgets.QToolButton()
button.setToolTip('Add New Tab')
button.clicked.connect(self.addNewTab)
button.setIcon(self.style().standardIcon(
QtWidgets.QStyle.SP_DialogYesButton))
self.tabs.setCornerWidget(button, QtCore.Qt.TopRightCorner)
self.addNewTab()
def addNewTab(self):
text = 'Tab %d' % (self.tabs.count() + 1)
self.tabs.addTab(TabPage(self.tabs), text)
if __name__ == '__main__':
app = QtWidgets.QApplication(sys.argv)
window = Window()
window.setGeometry(600, 100, 300, 200)
window.show()
sys.exit(app.exec_())
Try it:
import sys
from PyQt5 import QtCore, QtWidgets
class TabPage(QtWidgets.QWidget):
def __init__(self, parent=None):
super().__init__(parent)
self.parent = parent # +
self.button_id = 0 # +

layout = QtWidgets.QVBoxLayout(self)
layout.addWidget(group)
grid = QtWidgets.QGridLayout(group)
testbutton = QtWidgets.QPushButton('Clear Text')
grid.addWidget(testbutton, 2, 2)
testbutton.clicked.connect(self.tab_match)
self.parent.currentChanged.connect(self.qtabwidget_currentchanged) # +
def tab_match(self):
#Do something with button ID here
print("\ndef tab_match: button_id-> {}".format(self.button_id)) # +
#QtCore.pyqtSlot(int)
def qtabwidget_currentchanged(self, index): # +
self.button_id = index
class Window(QtWidgets.QWidget):

self.tabs = QtWidgets.QTabWidget()
layout = QtWidgets.QVBoxLayout(self)
layout.addWidget(self.tabs)
button = QtWidgets.QToolButton()
button.setToolTip('Add New Tab')
button.clicked.connect(self.addNewTab)
button.setIcon(self.style().standardIcon(
QtWidgets.QStyle.SP_DialogYesButton))
self.tabs.setCornerWidget(button, QtCore.Qt.TopRightCorner)
self.button_id = 0
self.addNewTab()
def addNewTab(self):
text = 'Tab %d' % (self.tabs.count() + 1)
self.tabs.addTab(TabPage(self.tabs), text)
if __name__ == '__main__':

I have modified the answer given here as written below. The code is basically creating pushbuttons with a counter as pushButton_0, pushButton_1..
Here, I know that when I press to self.addButton I am creating widgets named like self.pushButton_0, self.pushButton_1 etc. So, my question is, how I'm supposed to use this pushbuttons? Because when I'm trying to do something like self.pushButton_0.clicked.connect(self.x), it' s telling me that "there is no attribute named 'pushButton_0'".
Thanks!

# main button
self.addButton = QtGui.QPushButton('button to add other widgets')
self.addButton.clicked.connect(self.addWidget)
# scroll area widget contents - layout

self.setup()
def setup(self):
print(self.Main.count)
name = "pushButton_"+str(self.Main.count)
print(name)
self.name = QtGui.QPushButton('I am in Test widget '+str(self.Main.count))
layout = QtGui.QHBoxLayout()
layout.addWidget(self.name)
self.setLayout(layout)
app = QtGui.QApplication(sys.argv)
myWidget = Main()
myWidget.show()
app.exec_()
After hours, I found the problem!
You have to declare the signal while creating the pushbutton!
To fix this, I rewrote the setup function as below;
def setup(self):
print(self.Main.count)
name = "pushButton_"+str(self.Main.count)
print(name)
self.name = QtGui.QPushButton('I am in Test widget '+str(self.Main.count))
self.name.clicked.connect(self.x) # self.x is any function
layout = QtGui.QHBoxLayout()
layout.addWidget(self.name)
self.setLayout(layout)
So know, you will run function x whenever you push the new created pushbuttons!
Basically, when the Switch Button is pressed, which is connected to the reconfigure method, I want everything in the reconfigure method to run as a separate thread/process so the main GUI is still accessible and not being blocked. Below is a watered down version of my code.
import sys, time
from PyQt4 import QtGui, QtCore
from PyQt4.Qt import *
#//Popup Class - Will appear when the Switch Button is pressed
class Popup(QWidget):
def __init__(self):

font = label_header.font()
font.setPointSize(24)
label_header.setFont(font)
#//Creating Static Labels that will be placed in the GUI
label_1 = QtGui.QLabel("Menu 1:")
label_2 = QtGui.QLabel("Menu 2:")
label_spacer = QtGui.QLabel("")
label_cfg = QtGui.QLabel("Current Configuration: '/tmp/directory_here' ")
global comboBox1
comboBox1 = QtGui.QComboBox()
comboBox1.addItem("1")
comboBox1.addItem("2")
global comboBox2
comboBox2 = QtGui.QComboBox()
comboBox2.addItem("3")

#//Switch Button!!!

switchButton.clicked.connect(self.reconfigure)
quitButton = QtGui.QPushButton('Quit')
quitButton.clicked.connect(QtCore.QCoreApplication.instance().quit)
#//Configure the grid layout
grid.addWidget(label_spacer, 0,0,9,9)
grid.addWidget(label_header, 0,0,1,6)

print " reconfiguring to option %s and option %s" %(txt1, txt2)
#
# This is where most of the work is done, and takes about 1/2 an hour for everything to run

#
print "all done!"
#//runner
def main():
app = QtGui.QApplication(sys.argv)
ex = Example()
sys.exit(app.exec_())
if __name__ == '__main__':
main()
I feel like I have to use threading and signals to accomplish this, but I am not having much luck. Any help would be greatly appreciated. Thank you!
