Our application uses embedded xulrunner. We override the default PromptService to provide custom dialogs for alert, prompt, etc by
componentRegistrar.RegisterFactory (PROMPTSERVICE_CID, aClassName, aContractID, MyPromptServiceFactory);
where,
PROMPTSERVICE_CID is "a2112d6a-0e28-421f-b46a-25c0b308cbd0"
CONTRACT_ID is "#mozilla.org/embedcomp/prompt-service;1"
When using XULRunner 1.9.* versions, this works perfectly and the call comes to MyPromptSerivceFactory. But, this doesn't work on newer XULRunner versions (>= 4.0)
I have modified the PROMPTSERVICE_CID to "7ad1b327-6dfa-46ec-9234-f2a620ea7e00" (copied from nsPrompter.manifest). While registering the factory I get the error NS_ERROR_FACTORY_EXISTS.
If I continue to use the old PROMPTSERVICE_CID, then nsIPromptService2 is not used instead nsIWindowCreator2.CreateChromeWindow2 is used to display alerts and prompts.
I have googled on this, but I couldn't find a solution to either fix the NS_ERROR_FACTORY_EXISTS error or for MyPromptServiceFactory to be used.
Any help/suggestions?
It would probably be better to use the existing prompt service the way Firefox does it rather than replace it. If you look at nsPrompter.openPrompt(), before opening a modal dialog it will try to locate and call a JavaScript function getTabModalPrompt() in the window containing the browser. It expects to get a promptBox element back and will call methods appendPrompt() and removePrompt() on it. Obviously, you don't have to give it a promptBox element, just something that behaves similarly - and displays a message any way you like.
But if you really want to replace system components, you shouldn't duplicate prompter's CID - use your own one but #mozilla.org/prompter;1 as contract ID (the old contract ID is for backwards compatibility only).

I released a Chrome DevTools extension a couple years ago that uses
chrome.devtools.panels.elements.createSidebarPane(title, callback)
to add an ExtensionSidebarPane. This worked fine until Chrome 92. Now the Pane is created with the title, but it is blank.
The calls I am using are still documented: https://developer.chrome.com/docs/extensions/reference/devtools_panels/, but the example code that I used has been moved to into the mv2-archive section of the google-extension-samples repo. And the chrome-query example code no longer works either. So maybe that means it is unsupported now. On the other hand, everything I have found so far seems to say v2 should be supported to the end of 2021. And I haven't found any alternative v3 examples of adding info to the devtools UI.
Obviously createSidebarPane is getting called, because the blank pane is created with the expected title. And intentionally throwing an error in the callback shows that it is getting called with the expected ExtensionSidebarPane object as a parameter, it's just that calling setExpression or setObject on it doesn't do anything. I am not seeing any other errors or warnings.
I would hate to retire my extension, since I know people use it, but I am not sure what else to try.
I'm working on a python (3.5) program that use a PyQt5 GUI. In the GUI, I need to add some help links to the documentation on a website. I manage to make it work with:
QDesktopServices.openUrl(QUrl("my_url"))
It works fine but I want to be sure that it will always be the case.
A quick and dirty unittest is to call the function and simply notice that there is no error. I would like to make a test that will check that the correct website page did show up. What should I use?
Checking for an error is not going to work at all, because Qt itself never raises errors (of course, Python or PyQt might do, but for completely unrelated reasons). The best you can do is check the return value of openUrl, which will simply return True or False depending on whether it was "successful". But note the following from the Qt docs for openUrl:
Warning: A return value of true indicates that the application has
successfully requested the operating system to open the URL in an
external application. The external application may still fail to
launch or fail to open the requested URL. This result will not be
reported back to the application.
If you want more control, I suggest you use Python's webbrowser module instead. This would, for example, allow you to register your own mock-browser class for the purposes of testing. The webbrowser module is written in pure Python and the code is quite straightforward.
I tried watir wiki example to access modal window. But was getting Argument error. I am trying with watir 3 version.
puts b.modal_dialog(:title, "showModalDialog Method Sample Target Page").exists?
puts b.modal_dialog(:title, "showModalDialog Method Sample Target Page").title
b.modal_dialog(:title, "showModalDialog Method Sample Target Page").close
b = Watir::Browser.new()
b.goto("http://samples.msdn.microsoft.com/workshop/samples/author/dhtml/refs/showModalDialog.htm")
b.button(:value,"Push To Create").click_no_wait
Error message
C:/Ruby193/lib/ruby/gems/1.9.1/gems/watir-classic-3.0.0/lib/watir-classic/contai
ner.rb:60:in `modal_dialog': wrong number of arguments (2 for 0) (ArgumentError) from C:/webtest/popup.rb:29:in `<main>'
Can some one help how to access modal window using watir 3
Thanks
The error you're receiving is saying that you're supplying more arguments than are actually taken by the method.
I've never had call to use the actual modal methods within Watir, but after quick experimentation with the page you supplied I was able to interact with the modal using the following:
b.goto("http://samples.msdn.microsoft.com/workshop/samples/author/dhtml/refs/showModalDialog.htm")
b.button(:id => "dCommand").click_no_wait
puts b.modal_dialog.text
In the above example I had it print out the text of the modal, but presumably any regular Watir command could be substituted.
It would appear that the requirement for an argument indicating which modal to interact with has been removed in Watir 3.0 or earlier (presumbaly because you can only interact with one?). I moved to Watir-webdriver as I primarily test in Firefox, so I'm not sure when this might have changed, but it does appear to be the case that it does not accept any arguments in 3.0.
I have a desktop application developed with wxPython. The applications runs fine under Windows and OSX (same codebase, no platform specific code). Everything works on Linux except drag and drop. I can drag just fine, but DoDragDrop always returns wx.DragCancel. I can however, drag from my application or to another app/desktop which excepts text and DoDragDrop returns wx.DragCopy.
It seems to me like the DropTargets aren't getting called. I've added debug statements to OnData, etc and they are never activated.
Has anyone seen this and know of a workaround?
Found a known issue in wxWidgets that was considered fixed, http://trac.wxwidgets.org/ticket/2763, I am able to recreate this issue on linux. I reopened the ticket.
In the meantime you can swap your StaticBoxSizers or BoxSizers. or...
This works....
parent = DropTargetCtrn.GetParent()
boxes = [x for x in parent.GetChildren() if type(x)==wx.StaticBox]
tmpParent = wx.Panel(parent)
for box in boxes:
box.Reparent(tmpParent)
box.Reparent(parent)
parent.Destroy()
This solution seems to lower the StaticBox in the window hierarchy so it don't interfere with drop events. Note, box.Lower() does not work.
I came across echofunc.vim today (from a link in SO). Since I'm rubbish at remembering the order of function parameters, it looked like a very useful tool for me.
But the documentation is a bit lean on installation! And I've not been able to find any supplementary resources on the internet.
I'm trying to get it running on a RHEL box. I've copied the script into ~/.vim/plugin/echofunc.vim however no prompt when I type in a function name followed by '('. I've tried adding
let g:EchoFuncLangsUsed = ["php","java","cpp"]
to my .vimrc - still no prompting.
I'm guessing it needs to read from a dictionary somewhere - although there is a file in /usr/share/vim/vim70/ftplugin/php.vim, this is the RH default and does not include an explicit function list.
I'm not too bothered about getting hints on the functions/methods I've defined - just trying to get hints for the built-in functions. I can see there is a dictionary file available here which appears to provide the resources required for echofunc.vim, I can't see how I set this up.
TIA,
It expects a tags file, the last line of the description describes exactly how to generate it:
ctags -R --fields=+lS .
It works here with PHP but not with JS. Your mileage may vary.
I didn't know about this plugin, thanks for the info.
You should try phpcomplete.vim, it shows a prototype of the current function in a scratchpad. It is PHP only, though.
