I'm writing app based on webkit (haskell).
I ran into unpleasant stuff: When I try to load image via 'file:', I get this console message: Not allowed to load local resource: file://resources/something.svg.
To fix it I wrote a few lines of code:
wvSettings <- webViewGetWebSettings webView
set wvSettings [webSettingsEnableUniversalAccessFromFileUris := True]
webViewSetWebSettings webView wvSettings
But the problem remained. So what should I do?

When I run this script "python3 script.py" everything is alright.
(I tried to run the script as a root, and other user too)
import music21
import os
# "qt.qpa.xcb: could not connect to display"
# "qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found."
os.putenv("QT_QPA_PLATFORM", "offscreen") #handle error above in my case
us = music21.environment.UserSettings()
us['musescoreDirectPNGPath'] = '/usr/bin/musescore3'
score = music21.converter.parse("myfile.musicxml")
score.write('musicxml.pdf', fp='song.pdf')
But when my django backend has to execute this code as a function to respond API call, its not working. I got:
QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-myusername'
This plugin does not support propagateSizeHints()
And if I remove part with "QT_QPA_PLATFORM", I got "qt.qpa.xcb" error.
I have not idea what to do.
I also tried to add following line in my gunicorn setup script but nothing changed.
export QT_QPA_PLATFORM=offscreen
Any ideas how to fix it ? What can be wrong ?
Server OS: Ubuntu 20.04
You probably need to also set XDG_RUNTIME_DIR. See https://github.com/cuthbertLab/music21/issues/260#issuecomment-834489173
I built up a shiny solution that is placed in a R-markdown file.
I use runtime: shiny_prerendered
When I do that obviously the code wants to create an html file within the directory but since it is on a network location I do recieve and error:
Error in shiny_prerendered_prerender(input_rmd, rendered_html, output_dir, :
Unable to write prerendered HTML file to \\192.168.88.150/Main/2.Applications/Program/app.html
Calls: <Anonymous> ... shiny_prerendered_html -> shiny_prerendered_prerender
Execution halted
It seems the issue here is that it tries to write to incorrectly specified directory - starting with "\\", rather than "\\\\", for example.
Couple of notes:
When I move the solution to my local pc - works perfectly fine
Everywhere in the code I'm using relative path of the sort "data.R", rather than "\\\\192.168.88.150\\Main\\2.Applications\\Program\\Data.R" since I'm about to move this to shinyapps.io
If I use runtime:shiny it again works perfectly fine on the server but this is probably due to no need to write down a file.
Any idea how to change the path for the html file or other workaround?
I have rights to write on this network location - that's for sure.
For a project we try to expand the Google Cloud Datalab with IPyWidgets. When we try out IPyWidgets in jupyter notebook (not in google-cloud-datalab) locally, everything run as expected (i.e. we tried to show a Text field, which worked). When we try to execute the same code in Google Cloud Datalab, it fails. In the web console we see following error:
Error 1:
Error message: "Class ipython.widget not found in registry "
Error stack: "load_class/<#http://localhost:8081/static/notebook/js/main.min.js:12751:28load_class#http://localhost:8081/static/notebook/js/main.min.js:12736:1CommManager.prototype.comm_open#http://localhost:8081/static/notebook/js/main.min.js:21802:31.proxy/i#http://localhost:8081/static/notebook/js/main.min.js:89:5486Kernel.prototype._handle_iopub_message#http://localhost:8081/static/notebook/js/main.min.js:23101:20Kernel.prototype._finish_ws_message#http://localhost:8081/static/notebook/js/main.min.js:22936:1Kernel.prototype._handle_ws_message/this._msg_queue<#http://localhost:8081/static/notebook/js/main.min.js:22926:39"

The strange thing is, is when google-cloud-datalab is running and we go to the jupyter notebook (on port 9000), and we execute the code over there it works.
Do we need to make changes to nb.html, and/or static.ts to make this work?
Question: Is there a way to execute IPyWidgets on Google Cloud Datalab?
Greetings, Brecht
Edit: I can now load the js and the css files from IPyWidgets in google-cloud-datalab (you need to change static.ts, for those who wonder). The only remaining issue (hopefully), is that we get following error:
"Error: Could not determine where the display message was from. Widget will not be displayed".
This is because
var cell = this.get_msg_cell(msg.parent_header.msg_id);
is null (line 556, of ipywidgets/widgets/js/manager.js). I assume that changing static.ts is not enough?
The:
"Error: Could not determine where the display message was from. Widget will not be displayed".
issue can be fixed by changing this line in datalab.js:
originalExecute.apply(this, [ code, callbacks, options ]);
to:
return originalExecute.apply(this, [ code, callbacks, options ]);
I tried to load new colorschemes in xml format from here and here
, so I copied the xmls to ~/.config/QtProject/qtcreator/styles, but when I go under Tools->Options->Text Edito->Color Scheme I get blank options under IntelliJ IDEA for each xml I added and when I choose one nothing changes. Also, when I try to change stylesheet with command
qtcreator -stylesheet=~/Downloads/stylesheet_1.css
I get
QCss::Parser - Failed to load file "~/Downloads/stylesheet_1.css"
QCss::Parser - Failed to load file "~/Downloads/stylesheet_1.css"
void DBusMenuExporterPrivate::addAction(QAction*, int): Already tracking action "Follow Symbol Under Cursor" under id 151
But the style changes nevertheless
I'm running Qt Creator 3.0.1(Qt 5.2.1) on Ubuntu 14.04LTE
This worked for me
Instead of
~/Downloads/stylesheet.css
Use absolute path
/home/username/Downloads/stylesheet.css
Cheers,
I usually use trigger.io to generate my ipa-Files for iOS. Now when I want to generate the file, I get the following error message:
Failed when running /usr/bin/codesign: codesign_allocate: object: /Users/mherceg/Desktop/ag-app/development/ios/device-ios.app/Forge malformed object (unknown load command 39)
/Users/mherceg/Desktop/ag-app/development/ios/device-ios.app: object file format unrecognized, invalid, or unsuitable
It worked yesterday, but now it doesn't. Any help is very welcome.
Thanks,

This is probably to do with v1.4.16 of our platform, where we switched over to building on Xcode 4.5: I'd recommend upgrading Xcode and make sure the Command-line Tools (Preferences ↦ Downloads) are installed.
