Copy multiple images to clipboard

Question

I have multiple JPG files in a folder. I want to copy all of them to clipboard in one go, so when I press ctrl+v I can paste them.

Shutil will copy and past files from dict to dict:

from PyQt6 import QtCore, QtGui

for _ in range(10):
    app = QtGui.QGuiApplication([])
    data = QtCore.QMimeData()
    url = QtCore.QUrl.fromLocalFile(full_file_name)
    data.setUrls([url])
    app.clipboard().setMimeData(data)

This code will only copy one random image to the clipboard from the path I set. If I loop through all the files it crashes.

enter image description here

What do you mean by "crashes"? Did it throw an error and stop? Or did it just do nothing at all? Or did it stop the program? — 12944qwerty, May 05 '21 at 02:35
it copy the first images than say canot be a nonetype when i use if type(data) != None: it closes all the code suddenly with error 0xc0000005 — Akali DZ, May 05 '21 at 02:45
What says cannot be a NoneType. Can you paste the entire traceback into your question? — 12944qwerty, May 05 '21 at 02:46
but it copy one image and i can past it but than crashes like shown in the pics ... want it to coppy all images — Akali DZ, May 05 '21 at 03:26
@AkaliDZ The problem is not copying images but it seems that Qt has problems creating (or accessing) the native clipboard. Please use `@username`. You can provide a real [MRE] since by analyzing the image I can see that it is part of a more complex code that could be the cause of the error. — eyllanesc, May 05 '21 at 03:28
@AkaliDZ We cannot give you any alternative if you do not provide an MRE, if you do not provide it then I will vote to close your post since it is not reproducible. — eyllanesc, May 05 '21 at 03:33
@eyllanesc i opned a new python file and test this particular part of the code and it shows the same error . i wonder if there is a way to seperate urls and use them like this data.setUrls([url], [url2], [url3]...etc) — Akali DZ, May 05 '21 at 03:35
@AkaliDZ Show the error message as text and match your new code as I don't believe you. — eyllanesc, May 05 '21 at 03:36
@AkaliDZ move `app = QtGui.QGuiApplication([])` before for loop — eyllanesc, May 05 '21 at 03:39
@eyllanesc it doesnt show any erros but it only keeps the last elemnt in the clipord — Akali DZ, May 05 '21 at 03:41
@eyllanesc i know that the answer is here : data.setUrls([url, url1, url2, url3]) but how can i get evry url alone from the loop — Akali DZ, May 05 '21 at 03:53

The problem of the OP (shown in the image) is that he is creating several QGuiApplications and that cannot be done since it is a singleton.

The solution is to create a QGuiAplication before the for loop and then access through the static method QGuiApplication.clipboard():

import os

from PyQt6 import QtCore, QtGui

path = os.getcwd()

urls = []

it = QtCore.QDirIterator(path, ("*.jpg",), QtCore.QDir.Filters.Files)

while it.hasNext():
    url = QtCore.QUrl.fromLocalFile(it.next())
    urls.append(url)

if QtGui.QGuiApplication.instance() is None:
    app = QtGui.QGuiApplication([])

data = QtCore.QMimeData()
data.setUrls(urls)
QtGui.QGuiApplication.clipboard().setMimeData(data)
