I want to delete all attribute of block inside drawing using AutoLISP ObjectDBX method.

The below program works well: it deletes the attributes of all blocks inside the drawing, but when I edit this block in the Block Editor, I see all the attributes are still there.

I think I need to delete this attribute from definition of block.

I was trying to make the text in a QMessageBox selectable, and I found that if i modify the "setTextInteractionFlags" on QMessageBox, this solves the problem. However, when I tried to do this, my PyQt (or more specifically, PySide) complains that this attribute does not exist. So I instead try to add this feature in as a style sheet, however upon trying to create my own custom class of QMessageBox, this does not seem to work at all.

I then tried to make a QMessageBox manually, and that seemed to work.

Here is the code:

I have two line-edits (le_A and le_B) that only take numeric values and a check-box (chk_box). I am having issues in getting le_A and le_B to have the same inputs (see Scenario 2 below) whenever chk_box is checked (where chk_box is the 'controller').

Example scenarios:

• Scenario 1. User can input in any value in le_A or le_B when it is unchecked. For example, value in le_A is 10, while le_B is 20.

• Scenario 2. Any values that User input in le_A and le_B will be the same when it is checked. For example, if I input 10 into le_A, le_B will be 10. And the same goes for input done in le_B - the same value will be shown in le_A.

I've got a live matplotlib graph in a PyQt5 window:

Please copy-paste the code below to a python file, and run it with Python 3.7:

Some years ago, I already experimented with embedding live matplotlib plots in a PyQt5 GUI. Live plots show a data-stream real-time, captured from a sensor, some process, ... I got that working, and you can read the related posts here:

• Matplotlib animation inside your own GUI

• How do I plot in real-time in a while loop using matplotlib?

Now I need to do the same thing again. I remember my previous approach worked, but couldn't keep up with fast datastreams. I found a couple of example codes on the internet, that I'd like to present to you. One of them is clearly faster than the other, but I don't know why. I'd like to gain more insights. I believe a deeper understanding will enable me to keep my interactions with PyQt5 and matplotlib efficient.

This example is based on this article:
https://matplotlib.org/3.1.1/gallery/user_interfaces/embedding_in_qt_sgskip.html
The article is from the official matplotlib website, and explains how to embed a matplotlib figure in a PyQt5 window.

I did a few minor adjustments to the example code, but the basics are still the same. Please copy-paste the code below to a Python file and run it:

Im working on adding a visibility icon for the password field. I want the icon positioned to the right of the password text. But when I put the image button inside the TextInputLayout it forces the button to be below the password field. I am unable to put in on the right of it.

Here is the structure of the activity

My purpose is to build a rightmouse-click-menu like this:

When the user clicks on Grab and move, the button should disappear from the QScrollArea() and move quickly towards the mouse. When it arrives at the mouse pointer, the button should fade out and the drag-and-drop operation can start.

I got something working, but it isn't perfect yet. Please copy-paste the code below and run it with Python 3.x (I use Python 3.7) and PyQt5.

Note: To make the line pixmap = QPixmap("my_pixmap.png") work properly, let it refer to an existing png-image on your computer.

I'm working in Python 3.7 on Windows 10 and use PyQt5 for the GUI. In my application, I got a QScrollArea() with an array of buttons inside. When clicked, a button has to move outside the area. I use a QPropertyAnimation() to show the movement.

I've created a small application for testing. The application shows a small QScrollArea() with a bunch of buttons inside. When you click on a button, it will move to the right:

I'm trying to build a widget structure which will have a base widget which is derived from QtGui.QWidget, then I'll put the base features I want in every widget I create. Once the base widget is done, i'll create other types of widgets derived from the base widget.
