I refer to the article1 to build my GUI by PyQt5,The difference between the program of the article and mine is the module <img_controller.py>. When I initilize my img_controller instance,I only need the parameter ui(the class I got from Qtdesigner)and my program ,img_controller. will revise the attributes of ui. Initialize the parameters of img_controller.py according to 1 are directed inputted attributes of ui.
When I run the program got from 1, it can work normally; but I run my program, I can't get the mainwindow and the wrong message hints that "AttributeError: 'Img_controller' object has no attribute 'ui'".I don't know where is my problem, because in the function __ init __ of Img_controller(class), I state that "self.ui = ui",anyone can tell me the problem, thank you very much.
The following is my program:

What you DIDN'T say was the key piece of information -- the rest of the traceback. Notice that Img_controller.__init__ calls self.read_img, which calls self.set_img_ratio, which calls self.__update_img, which uses self.ui, and that all happens BEFORE you set self.ui. You need to swap the order of that initialization.
This question already has answers here:
Qt 4: Move window without title bar
(2 answers)
Closed 2 years ago.
I am trying to make an image viewer in PyQt5 with Python.
So far I have the functionality I want at the moment, this is a matter of styling the GUI how I would like it.
It looks almost how I want it.
I struggled to get that transparentish background, but managed to by setting windowflags to FramelesswindowHint. Unfortunately, now I don't have a menubar to close the application if I want to and drag the window around. I figure I will have to craft my own bar if I want to style it in a way that suits my background, which is fine, adding an X button to close the window shouldn't be too much of an issue.
My question is, how do I make it so I can drag the window around? I could make a rectangle widget and position it at the top with my buttons, but how do I get the whole window to move if the user clicks and drags it? I know similar questions are around, but I'm not sure how to make click and drag functions yet on objects in PyQt5 and it seems they use different layout strategies so I'm finding them confusing.
Here is my code:
from PyQt5 import QtCore, QtGui, QtWidgets

def __init__(self):
cwd = r"C:\Users\chees\PycharmProjects\PYQT5GUI\images"

Do not modify the code generated by Qt Designer but create another class that inherits
from the appropriate widget and use the initial class to fill it.
One of the ways to drag a window might look like this:
self._old_pos = None
def mousePressEvent(self, event):
if event.button() == QtCore.Qt.LeftButton:
self._old_pos = event.pos()
def mouseReleaseEvent(self, event):

self._old_pos = None
def mouseMoveEvent(self, event):
if not self._old_pos:
return
delta = event.pos() - self._old_pos
self.move(self.pos() + delta)

I'm trying to segment an image using Qlabels, these Qlabels are placed on an image then the segmentation will be done by pressing the segment button, I have done working on cropping function, its work but the result of the cropped images are not matched with the exact location of labels on the image.
Here is my code:
def crop(self):
i=1
image = self.UserImageLbl.pixmap()
for label in self.labels:
currentQRect = label.geometry()
#pixmap_rect = self.UserImageLbl.geometry()
tr = QtGui.QTransform()
r = tr.mapRect(currentQRect)
cropQPixmap = image.copy(r)
cropQPixmap.save('OUT '+str(i)+'.png')
i=i+1

can someone tell me what's wrong with my code!
Thanks
First of all do not modify the code generated by Qt Designer but you must create a class that inherits from a widget and use the generated class to fill it.
On the other hand considering the above a simpler solution than to make a crop in the QPixmap is to record a section of the window.

How to animate position,scale or any other attributes of composed elements inside custom widget, on mouse pointer enters or leaves the QListWidgetItem ?
(see reference image below)
And is there any better way to manage space around ListWidgetItem ?
item_widget.sizeHint() gives unwanted extra space, which is why i added hard coded value to setSizeHint.
