I'm working on a gui tool-- I'm building it with Pyqt5. I'm speifically NOT using QT designer. I'm using an MDI widget to keep everyhing a bit tidier.
Furthermore, so that my code is more crisp and less redundant, I'm building out each child window in a separate window in the same directory and then just importing the appropriate class from the individual files.
The problem is, whenver I import the subwindows, the are scaled up in the MDI subwindow. I am at a loss as to how I can address this. Has anyone expierenced something similar? I've added simplied code for my MDI subwindow below, followed by the code for one of the subwindows thta I'm importing. Any assistance would be greatly appreciated.

I'm trying to make a drag and drop behavior in QFileSystemModel but because I have no experience in making a drag and drop before, I tried it first on QTreeView. (I attached the video of the behavior)
Now that I'm fine with the behavior I want, I then just changed the model to QFileSystemModel but sadly It's not working. So I tried to read the QFileSystemModel, QTreeView, and Drag and Drop from Qt and I ended up with the code below:
The code I ended up with:
import os
import sys
from PyQt5.QtCore import *
from PyQt5.QtWidgets import *
from PyQt5.QtGui import *
class MQTreeView(QTreeView):
def __init__(self, model):
super().__init__()
self.setSelectionMode(QAbstractItemView.ExtendedSelection)
# self.setDragDropMode(QAbstractItemView.InternalMove)
self.setModel(model)
self.setDragDropMode(QAbstractItemView.DragDrop)
self.setRootIndex(model.index(os.path.dirname(os.path.abspath("__file__"))))
self.setDefaultDropAction(Qt.MoveAction)
self.viewport().setAcceptDrops(True)
def dragEnterEvent(self, event):
m = event.mimeData()
if m.hasUrls():
event.accept()
return
event.ignore()
# return super().dragEnterEvent(event)
def dropEvent(self, event):
print("[drop event] - dropped")
if event.source():
QTreeView.dropEvent(self, event)
else:
ix = self.indexAt(event.pos())
model = self.model()
if ix.isValid():
if not model.isDir(ix):
ix = ix.parent() # In case of folder/Dir
pathDir = model.filePath(ix)
else:
# for empty drag and drop
pathDir = model.rootPath()
m = event.mimeData()
if m.hasUrls():
urlLocals = [url for url in m.urls() if url.isLocalFile()]
accepted = False
for urlLocal in urlLocals:
path = urlLocal.toLocalFile()
info = QFileInfo(path)
n_path = QDir(pathDir).filePath(info.fileName())
o_path = info.absoluteFilePath()
if n_path == o_path:
continue
if info.isDir():
QDir().rename(o_path, n_path)
else:
qfile = QFile(o_path)
if QFile(n_path).exists():
n_path += "(copy)"
qfile.rename(n_path)
print(f"added -> {info.fileName()}")
accepted = True
if accepted:
event.acceptProposedAction()
# return super().dropEvent(event)
class AppDemo(QWidget):
def __init__(self):
super().__init__()
# -- right -- #
self.model1 = QFileSystemModel()
self.model1.setRootPath(os.path.dirname(os.path.abspath("__file__")))
self.view1 = MQTreeView(self.model1)
# -- left -- #
self.model2 = QFileSystemModel()
self.model2.setRootPath(os.path.dirname(os.path.abspath("__file__")))
self.view2 = MQTreeView(self.model2)
# -- layout -- #
layout = QHBoxLayout(self)
layout.addWidget(self.view1)
layout.addWidget(self.view2)
app = QApplication(sys.argv)
main = AppDemo()
main.show()
app.exec_()
The code above is still not doing the behavior I want but I'm pretty sure that something else is wrong and it is not with the overridden function (dragEnterEvent and dropEvent). My best guess is that I didn't set properly the correct way QTreeView accepts the drops although I'm not really sure.
My Question: What is wrong with my Implementation? Is it the way I accept drops or it is something else?
Found what's wrong! I didn't override the dragMoveEvent method. I need to override the dragMoveEvent to make sure that the drag will not be forbidden.
I need to accept all drag event in the dragEnterEvent:
def dragEnterEvent(self, event):
event.accept()
Then I need to filter the events in the dragMoveEvent:
def dragMoveEvent(self, event):
m = event.mimeData()
if m.hasUrls():
event.accept()
print("[dropEnterEvent] - event accepted")
return
event.ignore()
I attached the video and code of the working behavior below.
The final implementation:
import os
import sys
from PyQt5.QtCore import *
from PyQt5.QtWidgets import *
from PyQt5.QtGui import *

accepted = False
for urlLocal in urlLocals:
path = urlLocal.toLocalFile()
info = QFileInfo(path)
destination = QDir(pathDir).filePath(info.fileName())
source = info.absoluteFilePath()
if destination == source:
continue # means they are in the same folder
if info.isDir():
QDir().rename(source, destination)
else:
qfile = QFile(source)
if QFile(destination).exists():

if n_info.completeSuffix(): # for moving files without suffix

1) select all the items or the items to be pasted
2) copy it
3) paste it
if we have design pattern have item1 followed by item2 followed by item3 with respective distance. When we copy and paste it it should follow the same pattern.
QGraphicsItem.setPos() is absolute to the scene (or relative to its parent), the alternative solution is to use moveBy(x, y) (which is the same as setPos(self.pos() + deltaPos), but you have to take into account the relative position of the click according to the reference point.
I'd suggest you to not set the position until all items have been added, and then set their position according to a specific item that will be used as an "anchor" point.

it = ds_to_item(ds)
items.append(it)
if not topLeft:
topLeft = it
elif it.y() < topLeft.y() or it.x() < topLeft.x():
# find a possible topmost/leftmost item
topLeft = it
# add items, but do not set their position here
# ...
delta = self.scene.grid - topLeft.pos()
[i.moveBy(delta.x(), delta.y()) for i in items]
An alternative is to find the "anchor" in the copy procedure, and set the position of each item relative to that point in the datastream, so that you'll be able to use moveBy(pos2.x(), pos2.y()) directly after adding the items.
I'm new in PyQt5. I made a tabWidget where I was able to connect a button to add tabs dynamically and remove/close them. Before inserting tabs with button.Clicked, there's one open (already inserted) tab saying "no tabs are open". I would like to close this tab after inserting a new tab and reopen the tab after closing all new tabs (when no tabs are open). I couldn't find any example on how to use QTabWidget::tabInserted(int index) from http://doc.qt.io/qt-5/qtabwidget.html. Does anyone know how to use tabInserted and tabRemoved to detect when triggered. I would like to increment each time a tab is inserted and decrement when removed, to know when there are open tabs and no open tabs. Thanks
self.toolButton.clicked.connect(self.button_addtab)
self.tabWidget.tabCloseRequested.connect(self.close_tab)
def button_addtab(self, MainWindow):
_translate = QtCore.QCoreApplication.translate
self.tab_2 = QtWidgets.QWidget()
self.tab_2.setObjectName("tab_2")
self.tabWidget.addTab(self.tab_2, "")
self.tabWidget.setCurrentIndex(pages-0)
self.tabWidget.setTabText(self.tabWidget.indexOf(self.tab_2), _translate("MainWindow", "Second_tab"))
def close_tab(self, index):
self.tabWidget.removeTab(index)
I tried this:
if self.tabWidget.count() <= 0:
#Add the "no tab open" tab
self.tab_3 = QtWidgets.QWidget()
self.tab_3.setObjectName("tab_3")
self.tabWidget.addTab(self.tab_3, "")
_translate = QtCore.QCoreApplication.translate
self.tabWidget.setTabText(self.tabWidget.indexOf(self.tab_3), _translate("MainWindow", "Info"))
elif self.tabWidget.count() > 0:
self.tabWidget.removeTab(self.tabWidget.indexOf(self.tab_3))
This work, but it doesn't add after closing and it reopens after one more tab is added. That's why I would like to use tabInserted

Hello, how i can change the background color in specific rows in QTableview?
I would like to know which method to use to make.
I have the method seleckRow but click another the color is not maintained in the selected row.

How can I make from this python file *the class file* which would be ready to publish it on website as an applet?
