How to make QCompletter shown description in QTextEdit beside

I'm using PyQt, trying to make QLineEdit field, that's have QCompletter and it's work. But i want that when user choose words from Completter widget it's shown a description right from Completter. I think its look so
I created a Qwidget class that have Hlayout wtih Qcompletter and QTextEdit inside. But when i run my code QtextEdit show in new window, not near with Completer.
class Custom_Completer(QWidget):
completer = None
describe = None
lb = None
def __init__(self):
super().__init__()
self.completer = QCompleter([])
self.describe = QTextEdit()
self.completer.setCaseSensitivity(Qt.CaseInsensitive)
self.completer.setCompletionMode(QCompleter.PopupCompletion)
self.completer.setMaxVisibleItems(10)
self.completer.highlighted.connect(self._highlited)
self.completer.activated.connect(self._activated)
self.describe.setReadOnly(True)
self.describe.setObjectName('autoCompeteInfoFrame')
self.describe.setFixedWidth(200)
self.describe.setLineWrapMode(QTextEdit.WidgetWidth)
self.describe.setText('Description here')
self.lb = QHBoxLayout()
self.lb.addWidget(self.completer.widget())
self.lb.addWidget(self.describe)
self.setLayout(self.lb)
def _highlited(self):
self.describe.show()
self.show()
print('highlited show QTextEdit')
def _activated(self):
self.describe.hide()
print('activated QTextEdit in description')
def main():
completer = Custom_Completer()
completer.setModel(['500', '5000','500000'])
line_edit.setCompleter(completer.completer)

PyQt5 removing button

In the list_widget I have added a add button I also want to add a remove button which asks which item you wants to remove and remove the chosen item. I was trying it to do but I didn't had any idea to do so .Also, please explain the solution I am a beginner with pyqt5 or I'd like to say absolute beginner.
from PyQt5 import QtWidgets
from PyQt5.QtWidgets import QApplication,QMainWindow,
QListWidget, QListWidgetItem
import sys
class MyWindow(QMainWindow):
def __init__(self):
super(MyWindow, self).__init__()
self.x = 200
self.y = 200
self.width = 500

The core issue here is the lack of separation of the view and the data. This makes it very hard to reason about how to work with graphical elements. You will almost certainly want to follow the Model View Controller design paradigm https://en.wikipedia.org/wiki/Model%E2%80%93view%E2%80%93controller
which offers a systematic way to handle this separation.
Once you do so, it immediately becomes very straight forward how to proceed with the question: You essentially just have a list, and you either want to add a thing to this list, or remove one based on a selection.
I include an example here which happens to use the built-in classes QStringListModel and QListView in Qt5, but it is simple to write your own more specialized widgets and models. They all just use a simple signal to emit to the view that it needs to refresh the active information.
from PyQt5.QtWidgets import *
from PyQt5.QtCore import *
import sys
class StuffViewer(QMainWindow):
def __init__(self, model):
super().__init__()
self.setWindowTitle("Stock managment")
# 1: Use layouts.
hbox = QHBoxLayout()
widget = QWidget()
widget.setLayout(hbox)
self.setCentralWidget(widget)
# 2: Don't needlessly store things in "self"
vbox = QVBoxLayout()
add = QPushButton("+")
add.clicked.connect(self.add_new_stuff)
vbox.addWidget(add)
sub = QPushButton("-")
sub.clicked.connect(self.remove_selected_stuff)
vbox.addWidget(sub)
vbox.addStretch(1)
hbox.addLayout(vbox)
# 3: Separate the view of the data from the data itself. Use Model-View-Controller design to achieve this.
self.model = model
self.stuffview = QListView()
self.stuffview.setModel(self.model)
hbox.addWidget(self.stuffview)
def add_new_stuff(self):
new_stuff, success = QInputDialog.getText(self, 'Add stuff', 'Enter new stuff you want')
if success:
self.stuff.setStringList(self.stuff.stringList() + [new_stuff])
def remove_selected_stuff(self):
index = self.stuffview.currentIndex()
all_stuff = self.stuff.stringList()
del all_stuff[index.column()]
self.stuff.setStringList(all_stuff)
def window():
apk = QApplication(sys.argv)
# Data is clearly separated:
# 4: Never enumerate variables! Use lists!
stuff = QStringListModel(["Foo", "Bar", "Baz"])
# The graphical components is just how you interface with the data with the user!
win = StuffViewer(stuff)
win.show()
sys.exit(apk.exec_())
window()

How to have two widgets in one Main window

I am trying the whole morning already to fix that.
So I have a PyQt Main Window where I want to display two widgets.
In the first widget there are articles listed (which works so far).
When I click on them until now a QMessageBox is opening, but I want that
a second widget is opening where I can read the RSS Feed.
But this is not working. See Code below:
class ArticleWidgets(QWidget):
def __init__(self, *args):
super().__init__(*args)
self.setGeometry(610, 610, 600, 600)
self.initUi()
def initUi(self):
self.box = QHBoxLayout(self)
def show(self, feed=None):
self.title = QLabel()
self.summary = QLabel()
self.link = QLabel()
if feed:
self.title.setText(feed[0])
self.summary.setText(feed[1])
self.link.setText(feed[2])
self.box.addWidget(self.title)
self.box.addWidget(self.summary)
self.box.addWidget(self.link)
self.setLayout(self.box)
class TitleWidgets(QWidget):
def __init__(self, *args):
super().__init__(*args)
self.setGeometry(10, 10, 600, 600)
self.initUi()
def initUi(self):
vbox = QHBoxLayout(self)
self.titleList = QListWidget()
self.titleList.itemDoubleClicked.connect(self.onClicked)
self.titleList.setGeometry(0, 0, 400, 400)
self.news = ANFFeed()
for item in self.news.all_feeds:
self.titleList.addItem(item[0])
vbox.addWidget(self.titleList)
def onClicked(self, item):
feeds = self.news.all_feeds
id = 0
for elem in range(len(feeds)):
if feeds[elem][0] == item.text():
id = elem
summary = feeds[id][1] + '\n\n'
link = feeds[id][2]
if feeds and id:
#ANFApp(self).show_articles(feeds[id])
show = ANFApp()
show.show_articles(feed=feeds[id])
QMessageBox.information(self, 'Details', summary + link)
class ANFApp(QMainWindow):
def __init__(self, *args):
super().__init__(*args)
self.setWindowState(Qt.WindowMaximized)
self.setWindowIcon(QIcon('anf.png'))
self.setAutoFillBackground(True)
self.anfInit()
self.show()
def anfInit(self):
self.setWindowTitle('ANF RSS Reader')
TitleWidgets(self)
#article_box = ArticleWidgets(self)
exitBtn = QPushButton(self)
exitBtn.setGeometry(600, 600, 100, 50)
exitBtn.setText('Exit')
exitBtn.setStyleSheet("background-color: red")
exitBtn.clicked.connect(self.exit)
def show_articles(self, feed=None):
present = ArticleWidgets()
present.show(feed)
def exit(self):
QCoreApplication.instance().quit()

Solution using Pyqtgraph's Docks and QTextBrowser
Here is a code trying to reproduce your sketch. I used the Pyqtgraph module (Documentation here: Pyqtgraph's Documentation and Pyqtgraph's Web Page) because its Dock widget is easier to use and implement from my perspective.
You must install the pyqtgraph module before trying this code:
import sys
from PyQt5 import QtGui, QtCore
from pyqtgraph.dockarea import *
class DockArea(DockArea):
## This is to prevent the Dock from being resized to te point of disappear
def makeContainer(self, typ):
new = super(DockArea, self).makeContainer(typ)
new.setChildrenCollapsible(False)
return new
class MyApp(QtGui.QMainWindow):
def __init__(self):
QtGui.QMainWindow.__init__(self)
central_widget = QtGui.QWidget()
layout = QtGui.QVBoxLayout()
central_widget.setLayout(layout)
self.setCentralWidget(central_widget)
label = QtGui.QLabel('This is a label, The widgets will be below')
label.setMaximumHeight(15)
## The DockArea as its name says, is the are where we place the Docks
dock_area = DockArea(self)
## Create the Docks and change some esthetic of them
self.dock1 = Dock('Widget 1', size=(300, 500))
self.dock2 = Dock('Widget 2', size=(400, 500))
self.dock1.hideTitleBar()
self.dock2.hideTitleBar()
self.dock1.nStyle = """
Dock > QWidget {
border: 0px solid #000;
border-radius: 0px;
}"""
self.dock2.nStyle = """
Dock > QWidget {
border: 0px solid #000;
border-radius: 0px;
}"""
self.button = QtGui.QPushButton('Exit')
self.widget_one = WidgetOne()
self.widget_two = WidgetTwo()
## Place the Docks inside the DockArea
dock_area.addDock(self.dock1)
dock_area.addDock(self.dock2, 'right', self.dock1)
## The statment above means that dock2 will be placed at the right of dock 1
layout.addWidget(label)
layout.addWidget(dock_area)
layout.addWidget(self.button)
## Add the Widgets inside each dock
self.dock1.addWidget(self.widget_one)
self.dock2.addWidget(self.widget_two)
## This is for set the initial size and posotion of the main window
self.setGeometry(100, 100, 600, 400)
## Connect the actions to functions, there is a default function called close()
self.widget_one.TitleClicked.connect(self.dob_click)
self.button.clicked.connect(self.close)
def dob_click(self, feed):
self.widget_two.text_box.clear()
## May look messy but wat i am doing is somethin like this:
## 'Title : ' + feed[0] + '\n\n' + 'Summary : ' + feed[1]
self.widget_two.text_box.setText(
'Title : ' + feed[0]\
+ '\n\n' +\
'Summary : ' + feed[1]
)
class WidgetOne(QtGui.QWidget):
## This signal is created to pass a "list" when it (the signal) is emited
TitleClicked = QtCore.pyqtSignal([list])
def __init__(self):
QtGui.QWidget.__init__(self)
self.layout = QtGui.QVBoxLayout()
self.setLayout(self.layout)
self.titleList = QtGui.QListWidget()
self.label = QtGui.QLabel('Here is my list:')
self.layout.addWidget(self.label)
self.layout.addWidget(self.titleList)
self.titleList.addItem(QtGui.QListWidgetItem('Title 1'))
self.titleList.addItem(QtGui.QListWidgetItem('Title 2'))
self.titleList.itemDoubleClicked.connect(self.onClicked)
def onClicked(self, item):
## Just test values
title = item.text()
summary = "Here you will put the summary of {}. ".format(title)*50
## Pass the values as a list in the signal. You can pass as much values
## as you want, remember that all of them have to be inside one list
self.TitleClicked.emit([title, summary])
class WidgetTwo(QtGui.QWidget):
def __init__(self):
QtGui.QWidget.__init__(self)
self.layout = QtGui.QVBoxLayout()
self.setLayout(self.layout)
self.label2 = QtGui.QLabel('Here we show results?:')
self.text_box = QtGui.QTextBrowser()
self.layout.addWidget(self.label2)
self.layout.addWidget(self.text_box)
if __name__ == "__main__":
app = QtGui.QApplication(sys.argv)
window = MyApp()
window.show()
sys.exit(app.exec_())
Again, there are comments inside the code to help you understand what I did.
Here is how it looks:
If you pass the mouse between the two widgets you will see the mouse icon will change, with that you can readjust on the run the size of both widgets.
Final Words
This is another approach, more "interactive" and more esthetic than my previous answer. As you said, using a QSplitter works too.

Problems
The way you are building your GUI is, in my opinion, messy and it may lead to errors. I suggest the use of Layouts for a more organized GUI.
The other problem is that each widget is an independent class so if you want to connect an action in one widget to do something in the other widget through the Main Window, you must use Signals.
Edit : Another suggestion, use other name for the close function instead of exit and try using self.close() instead of QCoreApplication.instance().quit()
Solution
Trying to emulate what you want to do I made this GUI:
import sys
from PyQt5 import QtGui, QtCore
class MyWindow(QtGui.QMainWindow):
def __init__(self):
QtGui.QMainWindow.__init__(self)
## Generate the structure parts of the MainWindow
self.central_widget = QtGui.QWidget() # A QWidget to work as Central Widget
self.layout1 = QtGui.QVBoxLayout() # Vertical Layout
self.layout2 = QtGui.QHBoxLayout() # Horizontal Layout
self.widget_one = WidgetOne()
self.widget_two = WidgetTwo()
self.exitBtn = QtGui.QPushButton('Exit')
## Build the structure
# Insert a QWidget as a central widget for the MainWindow
self.setCentralWidget(self.central_widget)
# Add a principal layout for the widgets/layouts you want to add
self.central_widget.setLayout(self.layout1)
# Add widgets/layuts, as many as you want, remember they are in a Vertical
# layout: they will be added one below of the other
self.layout1.addLayout(self.layout2)
self.layout1.addWidget(self.exitBtn)
# Here we add the widgets to the horizontal layout: one next to the other
self.layout2.addWidget(self.widget_one)
self.layout2.addWidget(self.widget_two)
## Connect the signal
self.widget_one.TitleClicked.connect(self.dob_click)
def dob_click(self, feed):
## Change the properties of the elements in the second widget
self.widget_two.title.setText('Title : '+feed[0])
self.widget_two.summary.setText('Summary : '+feed[1])
## Build your widgets same as the Main Window, with the excepton that here you don't
## need a central widget, because it is already a widget.
class WidgetOne(QtGui.QWidget):
TitleClicked = QtCore.pyqtSignal([list]) # Signal Created
def __init__(self):
QtGui.QWidget.__init__(self)
##
self.layout = QtGui.QVBoxLayout() # Vertical Layout
self.setLayout(self.layout)
self.titleList = QtGui.QListWidget()
self.label = QtGui.QLabel('Here is my list:')
self.layout.addWidget(self.label)
self.layout.addWidget(self.titleList)
self.titleList.addItem(QtGui.QListWidgetItem('Title 1'))
self.titleList.addItem(QtGui.QListWidgetItem('Title 2'))
self.titleList.itemDoubleClicked.connect(self.onClicked)
def onClicked(self, item):
## Just test parameters and signal emited
self.TitleClicked.emit([item.text(), item.text()+item.text()])
class WidgetTwo(QtGui.QWidget):
def __init__(self):
QtGui.QWidget.__init__(self)
self.layout = QtGui.QVBoxLayout()
self.setLayout(self.layout)
self.title = QtGui.QLabel('Title : ---')
self.summary = QtGui.QLabel('Summary : ---')
self.link = QtGui.QLabel('Link : ---')
self.layout.addWidget(self.title)
self.layout.addWidget(self.summary)
self.layout.addWidget(self.link)
if __name__ == "__main__":
app = QtGui.QApplication(sys.argv)
window = MyWindow()
window.show()
sys.exit(app.exec_())
Inside the code, there are comments to help you understand why I did to build an organized GUI. There is also an example of a Signal being used to connect the action of itemDoubleClicked from the first widget to the second one. Here is how the MainWindow looks:
It is not very clear how the layouts work just from seeing the result, so I did a little paint over to a better understanding:
The blue box is the vertical layout (QVBoxLayout) and the red one is the horizontal layout (QHBoxLayout). Inside the blue layout, are located the red layout (above) and the exit button (below); and inside the red layout, are located the widget_1 (left) and the widget_2 (right).
Other Solution
An "easier" solution will be building the widgets inside the MainWindow instead of creating separate classes. With this you will avoid the use of signals, but the code will become a little more confusing because all the code will be cramped in one class.

Using 3 Buttons in PyQt5 DialogButtonBox

I'm attempting to create a Login System type dialog box for practice using PyQt5 (I'm quite new to the module) and i'm trying to give the user the ability to click (Ok, Cancel, Apply) as the buttons underneath inputs boxes for Username / Password, but i'm not sure how I can actually get the apply button to work. I have buttons.accepted.connect(*method*) and buttons.rejected.connect(*method*) but I don't know how to specify the pressing of the accept button. I have tried using buttons.clicked(dlgButtons[0] (Which is where the button is stored) but it just gives me an error.
The code below is my declaration of the buttons if that helps. Thanks
buttons = qt.QDialogButtonBox()
dlgButtons = (qt.QDialogButtonBox.Apply, qt.QDialogButtonBox.Ok, qt.QDialogButtonBox.Cancel)
buttons.setStandardButtons(
dlgButtons[0] | dlgButtons[1] | dlgButtons[2]
)

One possible solution might look like this:
from PyQt5.QtWidgets import *
class ModelessDialog(QDialog):
def __init__(self, part, threshold, parent=None):
super().__init__(parent)
self.setWindowTitle("Baseline")
self.setGeometry(800, 275, 300, 200)
self.part = part
self.threshold = threshold
self.threshNew = 4.4
label = QLabel("Part : {}\nThreshold : {}".format(
self.part, self.threshold))
self.label2 = QLabel("ThreshNew : {:,.2f}".format(self.threshNew))
self.spinBox = QDoubleSpinBox()
self.spinBox.setMinimum(-2.3)
self.spinBox.setMaximum(99)
self.spinBox.setValue(self.threshNew)
self.spinBox.setSingleStep(0.02)
self.spinBox.valueChanged.connect(self.valueChang)
buttonBox = QDialogButtonBox(
QDialogButtonBox.Ok
| QDialogButtonBox.Cancel
| QDialogButtonBox.Apply)
layout = QVBoxLayout()
layout.addWidget(label)
layout.addWidget(self.label2)
layout.addWidget(self.spinBox)
layout.addWidget(buttonBox)
self.resize(300, 200)
self.setLayout(layout)
okBtn = buttonBox.button(QDialogButtonBox.Ok)
okBtn.clicked.connect(self._okBtn)
cancelBtn = buttonBox.button(QDialogButtonBox.Cancel)
cancelBtn.clicked.connect(self.reject)
applyBtn = buttonBox.button(QDialogButtonBox.Apply) # +++
applyBtn.clicked.connect(self._apply) # +++
def _apply(self): # +++
print('Hello Apply')
def _okBtn(self):
print("""
Part : {}
Threshold : {}
ThreshNew : {:,.2f}""".format(
self.part, self.threshold, self.spinBox.value()))
def valueChang(self):
self.label2.setText("ThreshNew : {:,.2f}".format(self.spinBox.value()))
class Window(QWidget):
def __init__(self):
super().__init__()
label = QLabel('Hello Dialog', self)
button = QPushButton('Open Dialog', self)
button.clicked.connect(self.showDialog)
layout = QVBoxLayout()
layout.addWidget(label)
layout.addWidget(button)
self.setLayout(layout)
def showDialog(self):
self.dialog = ModelessDialog(2, 55.77, self)
self.dialog.show()
if __name__ == '__main__':
import sys
app = QApplication(sys.argv)
win = Window()
win.resize(300, 200)
win.show()
sys.exit(app.exec_())

What you are storing in the dlgButtons is just a list of enums, specifically the StandardButton enum, which is a list of identifiers for the buttons, they are not the "actual" buttons.
Also, you cannot use the clicked signal like this:
buttons.clicked(dlgButtons[0])
That will generate a crash, as signals are not callable. The argument of the clicked() signal is what will be received from the slot, which means that if you connect a function to that signal, the function will receive the clicked button:
buttons.clicked.connect(self.buttonsClicked)
def buttonsClicked(self, button):
print(button.text())
The above will print the text of the clicked button (Ok, Apply, Cancel, or their equivalent localized text).
What you're looking for is to connect to the clicked signals of the actual buttons, and you can get the individual reference to each button by using the button() function:
applyButton = buttons.button(qt.QDialogButtonBox.Apply)
applyButton.clicked.connect(self.applyFunction)

Pyside Qmenu Examples

Does anyone know examples about how to change a qMenu styles of lines separately ( change color of text of line , color of line bg, add underline to any texts inside texts etc. ) or if can't be done , can be solved anyhow ?
Thanks,
Szabolcs
share my code:
class MainWindow(QtGui.QMainWindow):
def init(self):
super(MainWindow, self).init()
self.menus = ['alma','korte','banan','ezmegaz']
acts = []
self.qmenu = QtGui.QMenu()
self.hip_fgrp = HipFileGroup( hip_data_file )
self.hip_fgrp.RemoveRepeats()
for i,hipf in enumerate(self.hip_fgrp.hipFileArr):
short_n = hipf.shortname
# prj = hipf.shortprjname
prj = ''
prj = hipf.shortprjname
if len(hipf.add_hipfolders):
prj = prj + ' \\ ' + hipf.add_hipfolders[0]
action = QtGui.QAction( prj+' \\ '+short_n, self, triggered=self.MenuSelected)
action.setData( i)
acts.append( action)
# print short_n
mpos = QtGui.QCursor
x = mpos.pos().x()
y = mpos.pos().y()
for action in acts:
self.qmenu.addAction(action)
self.qmenu.show()
self.qmenu.setGeometry( x-20, y-20, 0, 0)
self.qmenu.exec_()
def MenuSelected( self):
action = self.sender()
hipfile_id = action.data()
hipfile = self.hip_fgrp.hipFileArr[ hipfile_id]
hipfile.show_all()
hipfile_last = hipfile.getLastVersion( hipfile.hipfullspec)
print hipfile_last
if not in_sublime:
import hou
hou.hipFile.load( hipfile_last, hip_accept)

I don't know of any easy way. And it seems to be a long-standing question. But almost anything is possible with a bit of work:
Rather than using a QAction in your menu you can use a QWidgetAction which lets you customise the widget used to represent the action in the menu. Here I use a QLabel which supports rich text. However, bear in mind that the widget needs to handle the mouse itself (here I call trigger).
import sys
from PySide import QtGui
class MyLabel(QtGui.QLabel):
def __init__(self,action):
super(MyLabel,self).__init__()
self.action = action
def mouseReleaseEvent(self,e):
self.action.trigger()
class Example(QtGui.QMainWindow):
def __init__(self):
super(Example, self).__init__()
wAction = QtGui.QWidgetAction(self)
ql = MyLabel(wAction)
ql.setText("<b>Hello</b> <i>Qt!</i>")
wAction.setDefaultWidget(ql)
wAction.triggered.connect(self.close)
menubar = self.menuBar()
fileMenu = menubar.addMenu('&File')
fileMenu.addAction(wAction)
self.setGeometry(300, 300, 250, 150)
self.setWindowTitle('Menubar')
self.show()
app = QtGui.QApplication(sys.argv)
ex = Example()
sys.exit(app.exec_())
In a more fully featured example you might subclass QWidgetAction to handle different action contexts, and use different widgets, but this should get you started.
