Qt for Python

Hi and welcome to devnet, Are you looking for the currentChanged signal of your view's selection model ?

@philipsj33 You would not normally use any absolute positioning coordinates for widgets. It's not a good idea. Rather you would use Qt's QLayouts, as just about all widgets examples will do. have you started by reading https://doc.qt.io/qt-5/layout.html ?

Also I'm having trouble inserting the QTextFrame without it putting a newline in my QTextEdit. I don't know how to make it do that. The funny thing is it puts one before the QTextFrame but not one after it. Here's my code: def addmsg(textedit, nick, message): if config.show_timestamp: obj_now = datetime.now() textedit.insertPlainText(f"[{obj_now.hour: >2}:{obj_now.minute: >2}] ") textedit.cursor.insertText("<") nickframe = textedit.cursor.insertFrame(QTextFrameFormat()) nickframe.nick = nick framecursor = nickframe.firstCursorPosition() framecursor.insertText(nick) textedit.cursor.insertText("> ") colorify(textedit, message) textedit.cursor.insertHtml("<br>") Here's how it looks: < inhahe_> test

You have created the button variable without the "self." and you try to using it with the "self." you have to change this line: button = QPushButton('PyQt5 button', self) with this: self.button = QPushButton('PyQt5 button', self) and then you can access it with: self.button.move(400,250)

@DiGol have you started by reading https://doc.qt.io/qtforpython/tutorials/basictutorial/uifiles.html ?

yes , i've done all i can, and finally it's ok. and the problems seem to be in the widget where i put my buttons. all was create correctly but nothing was visible. i 've changed the kind of widget i use, and now it's ok. (i need to say that not is clear in my mind about how qt is working.) thanks for all @jsulm

@CarlosDiaz in order to show a context menu when right-click on the chart I don't know anything about QChart. But for QGraphicsView there is QGraphicsView::contextMenuEvent(). See the PyQt example at https://stackoverflow.com/a/14972629/489865 ?

I forgot to post here when I solved this. The issue was that rundll32 doesn't provide any output for the dll on Windows. I was testing through WINE which does provide output. The couple reports of the patching working and more reports of it not working was a separate issue with PyInstaller. Not having a setup for testing on actual Windows made this much more difficult than it should have been.

@DiGol PyQt5 uses/requires Qt5 and PyQt6 uses/requires Qt6.

@SGaist Thanks! For now I switched to clicked() which seems to be fine, but checked QSignalBlocker and it works too, good to know it exists. I'm new to Qt and it's really impressive how thought out to the details it is! And what's more important there are gurus who share their knowledge and respond quicker than tech support of most of the software dev companies :-) Thanks again!

@Abdulrahman Use the accepted signal: import QtQuick 2.13 import QtQuick.Controls 2.0 import QtQuick.Window 2.13 Window { width: 640 height: 480 visible: true title: qsTr("Hello World") onXChanged: function() { save.open(); } SaveDialog { id: save onAccepted: function() { rect.visible = true; } } Rectangle { id: rect width: 200 height: 200 color: 'red' visible: false Text { text: qsTr("Two") } } }

@SGaist thank you for the advice, I think that I will take you up on that!

Hi, Qt Stylesheet do not implement everything the CSS standard provide. You can start here.

oh, I tested other 10 digit numbers, but I failed to make them smaller than -2147483647 -214748366X doset allow anything for x, which makes sense ! You can add to the report if you like, it's going nowhere anyway. You may have noticed that the assigned person removed himself and the ticket is now "unassigned" and I doubt it will ever be touch upon again

@DiGol Yes, it is possible

@rodrigoml The problem with your original code is the line: model.setItem(0, item) since you always set the items to the first row.

@jash said in Need advice with new project (Should I use PyQT): @jeremy_k thanks, the diagram scene does look pretty similar to what I intend to do. Does it give the diagram information which I can use to know how the graph looks? I'm not quite clear on the question. If you're referring to generating a data structure suitable for traversing the graph, I believe that I implemented my own by adding code to the existing functions. E.g. DiagramItem.__init__() from the example linked below provides an opportunity to track new objects in the diagram. I'm okay with learning and don't want to run away from it. Is there a python example I can look at? For PySide/Qt for Python https://doc.qt.io/qtforpython-6/examples/example_widgets_graphicsview_diagramscene.html I recall seeing PyQt ports of the examples, but don't have a link handy.

@Tallhamer __feature__ must be imported after PySide6, also you must change setCentralWidget to set_central_widget: import sys from PySide6.QtWidgets import QApplication, QMainWindow, QPushButton from __feature__ import snake_case, true_property class MainWindow(QMainWindow): def __init__(self): super(MainWindow, self).__init__() self.setWindowTitle("My App") # This is using the functionality from __feature__ button = QPushButton("Click Me") button.enabled = False self.set_central_widget(button) app = QApplication([]) window = MainWindow() window.show() sys.exit(app.exec_())
