Copy text into clipboard

Coding

#1

In linux, anyone knows how to write data into clipboard memory ( like Ctrl + C)

I am try to read the text in a scrollField, and copy to clipboard ,
Instead of selecting text Ctrl + C, I like to make it a button.

Since you’re mentioning scrollField I think you’re already using Qt? If so, this code might be a good example for you.

clipboard = QtWidgets.QApplication.clipboard()
assert clipboard, "Must have running QApplication instance"
# Set to Clipboard
clipboard.setText(text)

If instead you’d like to actually put a file in your clipboard so you can paste it in your system’s explorer or a browser, etc. then this example code will help you. Which boils down to:

clipboard = QtWidgets.QApplication.clipboard()
assert clipboard, "Must have running QApplication instance"

# Build mime data for clipboard
data = QtCore.QMimeData()
url = QtCore.QUrl.fromLocalFile(path)
data.setUrls([url])

# Set to Clipboard
clipboard.setMimeData(data)

This should both work across different platforms, including linux.

thanks for the reply, I will give a try :slight_smile:

To correct myself, scrollField of course is not a Qt command but a Maya UI element from maya.cmds.

Anyway, in Maya you should still be able to access the Qt functions from PySide2. You can import those with:

from PySide2 import QtWidgets

It’s good to be aware that over the years Maya has had different versions of PySide and will likely upgrade with the next version to PySide6. So you might need to ensure you do the right imports in the right maya versions or use a library like Qt.py or qtpy or alike which tries to abstract away the different versions into a single library. But I believe Maya 2020-2024 at least were all using PySide2.

NB:

Unlike the cmdScrollFieldReporter command,
the ScrollFiel command does not have flags for selecting text and copying it to the clipboard.
The ScrollFiel command has flags for some simple manipulations with text content and its formatting.
For example, the command has flags to return all text or a selected part of it.

if cmds.window(my_window_name, exists = True):
    cmds.deleteUI(my_window_name)

    cmds.windowPref(my_window_name, enableAll = False, remove = True)
