I would like to know when the "Fix-it" should appear? Is it possible to make appear on all errors (and suggest a change?)
Clearly an error in my code, which "Fix-it" analyzed and detected.
But can it help me even more?
Unfortunately Fix-it doesn't support all errors/warnings. I've looked for a list of supported ones, with no such luck. It's likely that more will be added in future releases. It's still a very new feature, so Apple will see how things go and improve, adapt, and update.

For some reason, my QTableView seems to never emit a single signal. At first I tried connecting to any slot programmatically, but then I realized even through the Signal/Slot Editor from the GUI I could not make something happen, no matter which signal or slot I chose.
One detail that I noticed after a lot of research was that the Qt Documentation specifies that "The signal is only emitted when the index is valid.", so I understand this may be a problem with my models.
However, I still have no idea what might be the issue, or how I can fix it. Displaying the cells work perfectly fine on all models I have, but none of them seem to provide the correct signaling behavior, so I can't really detect the problematic code to post it.
It might be relevant to note, I tried disabling editing, and I'm testing this on Mac OS X Lion 10.7.5.
I appreciate any help. This is my first question here, although I've long benefited from those asked by others. So, yes, I've thoroughly searched for solutions.
Okay, I finally figured it out. After I realized Qt Creator was never updating the executable, no matter which code I changed, it was simply a matter of manually cleaning the build directory. Using the GUI options to do so (either rebuild or clean+build) hadn't had any effect. I guess it's because I had renamed the project, but didn't update the build directory or something. I had changed (improved) so much code since then that I would never have guessed there was an issue as everything was working fine, until I decided to add some more functionality.
As I had expected, this is kind of underwhelming for my first published issue, but I don't think it deserves negative points. The reason I didn't post some self-contained code is because I had no idea which code was causing the issue; I suppose I was just expecting someone with more experience to point me in the right direction. In the end, it wasn't even an issue with my code, it was with Qt Creator, so I really couldn't have been clearer.
I'll keep this as it might be useful for other people, so
tl;dr Qt Creator was silently failing to recompile the code, and the solution was to manually remove the old binaries.
I am trying to use plone 4 with deco, using this buildout: http://svn.plone.org/svn/plone/plone.app.deco/buildouts/dev/
It seems to work, but when I add the new page element nothing special happens. (No deco.gs)
Anyone knows what is happening? or know a way of making it work with plone 4?
Deco is still experimental as of this writing, and shouldn't be used in production just yet.
Steps to get it working (what's currently working, that is) can be found in the install docs:
http://svn.plone.org/svn/plone/plone.app.deco/trunk/docs/INSTALL.txt
As far as i am aware, there has recently been a refactoring leaving the Deco UI editor not in a workable state. It shouldn't be a lot of work to repair, but it would be best if one of the core developers would do it.
Your best bet is probably asking on the plone.dev list to make someone do a small development push.
I have been struggling with Xcode 3, and decided to jump directly to Xcode 4.
However, a big problem is that there is very little support like articles, videos, and projects I can use as templates.
Does there exist support like this at all?
Can I use Xcode 3 projects as templates?
Would it be easy to work from Xcode 3 tutorials?
I have now been using it for one day. Some things in the interface designer are quite different. For example, I can't get to subviews in the tab bar control (but mostly I manage, and can follow examples).
Thanks.
I'm doing the same thing. Xcode 4 is in pre-release, so there's not much in the way of tutorials while the tools are in a semi-NDA limbo and could be changed significantly before final release.
I highly recommend reading tutorials (I'm working my way through Aaron Hillegass' books on iPhone and OSX development) that use Xcode 3, and allowing extra time for learning where to map across to the new version.
Xcode 4 is much better organised, so it can be annoying but not impossible to find what you are looking for fairly quickly.
Resources you should go to first:
WWDC10 sessions 307, 308 and 315:
Introducing Xcode 4,
Developing your app with Xcode 4, and
Using Interface Builder in Xcode 4.
Access these through the developer portal. They are the definitive Apple guide to the new design and workflow.
In the Xcode 4 Help menu, the Xcode 4 Transition guide is the second choice. I skimmed it, then kept coming back to dive into topics when they came up.
Xcode 4, despite being "released", is an absolute disaster. I would wait for at least a couple of updates (beyond 4.01) before moving to it.
Basic functionality is severely broken. Breakpoints, syntax highlighting, basic functionality in the Interface Builder IU... I don't even know where to begin.
The document management, which was the towering defect of Xcode's design up to this point, has been changed but sadly not fixed. It might even be worse.
At first I had some good impressions. Early notes:
More-sensible defaults for debugging hotkeys.
There's now "Close project" in the File menu!
You can finally set up sounds for lots of build & search events, with a GUI. Nice.
There's a drop-down that shows files that are associated with the one you're editing. This might be useful, but any convenience this might add is ruined by the fact that there's no quick "counterpart" button like there used to be. You have to dig through a menu to go from header to source or vice versa.
Tabs are upside down, extending off the toolbar (WTF). Also, the "X" to close indicator is missing from each tab unless you roll over the tab. This kind of Easter-egg UI hides information from the user and should be abolished.
The tabs don't work well for a couple of reasons. First, there can be two editing panes under one tab with different documents; the tab only shows the name of one of them. You also can't move documents between panes, which you often want to do when referring to different objects and interfaces. Visual Studio solves both of those problems easily by having separate tab groups above each editing pane and letting you drag documents between the two groups.
A second editing pane is always referred to (and indicated in the toolbar) as an "Assistant" editor even if you didn't invoke the assistant (which is bafflingly denoted by a Batman icon button).
View options are under View, where they belong, instead of being incorrectly placed under the Window menu.
If you're typing a call to a function and you're using another function call as a parameter, Xcode's auto-completion appears to automatically prefer functions whose return type matches the parameter you're filling out. EXCELLENT.
But there are bugs aplenty. So many that it's very hard to get work done at times.
One particularly infuriating bug is Xcode's failure to indicate when and where it has stopped at a breakpoint. In many instances, it will stop and pull up the source file, but there's no execution point highlighted. The editor just shows the top of the file, and nothing happens as you step through. The current line is not highlighted, and nowhere does Xcode say, "Stopped at breakpoint." It just says "running."
There's no way to sort files your files in the treeview. NONE. Xcode 3 was bad enough in not sorting them automatically, making you go and sort them over and over and over through the life of a project. Now that's not even an option. WTF?
Xcode leaves your editor window littered with error highlights and messages even after you've fixed the code and recompiled. It turns out that these errors apply to a different target, even though you never built that target and the code they're complaining about doesn't exist anymore.
Xcode will overwrite your syntax-highlighting choices for specific symbol types. You can change them again and again, and Xcode will overwrite your settings inexplicably. You can watch it happen.
THERE'S NO "BUILD" BUTTON IN THE TOOLBAR, AND YOU CAN'T ADD ONE. In fact, the toolbar is not customizable at all, and there's only a "Run" button. What if you don't want to run? Yep, you have to look up the hotkey.
What did they do with all the extra space in the toolbar? Made the project-config dropdown NARROWER. It's so small that it can't show you WTF you're working on. Meanwhile, there's a vast strip of empty space right next to it. Unbelievable.
The Xcode team tried to clean up the mess that was project settings, adding the concept of "schemes." It's mostly an improvement, but buggy. But I'm out of time for this update...
I am not sure what kind of documentation they give you with Xcode 4, however there should be something in the help menu I imagine. WWDC also had a video on Xcode 4, it was their "State of Union" address. Here is a link to the iTunes videos.
Just to add to Luke's point, it all depends on how much code you know. I am going to stick with V3 as compile errors etc are not automatically fixed and I want to learn how the code works, this is going to help in the future.
Current tutorials (mostly about V3) will help you grasp the basics of Xcode, as V4 is easier overall but understanding the basics is the most important aspect.
Localization seems to be pretty significantly broken in 4.0, with constant crashes for me.
I would wait for 4.0.2, or something..
I just switched back to 3.2.6 after I tried out XCode 4. It has so many bugs and crashes, it was too frustrating. Also its updates are not included in the normal apple updates, you have to re install the whole software via the installer. Its ridiculous! Although the git integration and drop down syntax completion is cool, I think I will wait till 4.0.3 before updating again!
I've got this very odd bug that appears to be a quirk in Visual Studio 2010: Sometimes, when moving the cursor into double quotes of a CSS style="" attribute the cursor refuses to move. I can't type anything, and the keys that respond are the UP/DOWN cursor keys and the DEL key (but not BACKSPACE).
Typing does nothing, but pushing LEFT/RIGHT on the cursor keys produces the following error:
The operation could not be completed
I've got no idea what's causing this, but I would hazard a guess that Intellisense is getting very confused and bugging out.
At the moment, whenever this happens, I have to write any CSS outsite of the double quotes of the style attribute and then place the cursor where I want the CSS to appear (using the mouse) and press CTRL-V to paste it in. Very annoying :(
There must be a way of fixing this problem...?
Hopefully someone has an answer!
Just encountered the issue in VS 2012, in editing C#.
I noticed that the problem had occurred soon after the trial period of Resharper has ended and i inserted a valid license number. It also happened in only some of the source files.
The solution: Tools->Options->Resharper: Suspend.
Try typing - should work now.
Then: Tools->Options->Resharper: Resume.
Problem gone.
I have encountered this using Visual Studio 2013 and Resharper 8.2.1. None of the solutions provided in this thread worked (even suspending and resuming Resharper)
After contacting JetBrains support, it turned out to be a caching issue.
Deleting all the files from the following directory solved the issue, as Resharper re-creates new caches:
C:\Users\[Username]\AppData\Local\JetBrains\ReSharper\v8.2\SolutionCaches\[Project_reference]
I have some odd issues with the editor occasionally, a workaround for me is:
Ctrl-Tab (x2) to another code file and back to the same code (or alt tab to another app and back, one of these two... can't replicate issue to be sure)
An ultimate solution might be a re-install.
Microsoft have had variations on this problem reported quite a few times via their support portal. Here is one post and if you scroll down you will see a comment with a bunch of other reports all detailing similar(ish) problems.
Microsoft doesn't seem to be able to reproduce the problem but are "duping all the similar keyboard locking problems to a central bug, so that we can think a way to log the events if necessary". Which seems to be a generic response to a lot of these posts. Some people reported that it was simply becuase another window/pane/tab was in focus but I can see the OP obviously did not have this specific problem. Looks to me like one of those random unresolvable bugs. Hope I never get it! There's also numerous forum posts around the Internet, where users stated that removing certain 3rd party plugins has solved this issue.
I just spotted this particular post which has a possibly useful comment on it for you (which also link to this SO post. As I do not have the bug I cannot test its validity for you. The main point of it seems to be something about the keyboard layout switching.
I'm sorry for putting all this into an answer when technically it is not an answer and just a mass of research, but there was no way this was gonna fit into a comment. And also sorry for pretty much link spamming, but again there was no way I could extract everything that they said into this post. I hope there is something useful in there for you :)
EDIT: You should probably check the top rated answer below as this seems to solve a number of peoples issues, although I never had the Resharper plugin and still occasionally experienced this, but now I'm on VS2013 and have not had this problem re-occur, so maybe they fixed it...
Empty the solution cache folder
C:\Users\{UserName}\AppData\Local\JetBrains\ReSharper\v8.2\SolutionCaches\
This was suggested by JetBrains support when I contacted them.
Permanently fixing... Not too sure however I found that pressing pressing Ctrl+Shift+Caps Lock+Tab all at once seems to get rid of this and enables the mouse and keyboard again. I know this isn't the best of solutions but it works.
I have the same problem several times a day. I didn't notice it until I installed the web essentials extension. I just uninstalled it and will see what happens. I have tried reinstalling visual studio with no joy (but again, I didn't notice the problem until after I had already installed the various extensions).
Sometimes, closing and re-opening the specific code window I'm working in fixes it. If that fails, sometimes I close all windows and reopen just the one I was actively editing. If all of that fails it usually requires a complete restart of visual studio.
I find it funny that MSFT says that they can't duplicate the problem. Scott Guthrie experienced it first hand during his MVC4 beta demo here at about 28 minutes in.
UPDATE: So far, as of 4-5-2012 9:33am Central Time, the problem hasn't recurred since uninstalling Web Essentials. This is the longest I've gone without this bug occurring. If I make it through the next 24 hours, I'll be confident in blaming Web Essentials.
UPDATE: 4-6-2012 10:05am Central Time: Well, apparently it wasn't Web Essentials. It happened to me again this morning editing the contents of a block in my _Layout.vbhtml file. Closing the tab and reopening it fixed it.
I frequently encounter this editor freeze, not just on CSS quotes but any file arbitrarily. I have a dual monitor setp and I have the doucment windows one one monitor and all tool windows on the next one. Sometimes, certain tool windows would freeze too (i.e. not respond to click).
Previously, I used to shutdown/restart IDE; but serendipitously, I discovered that switching to/from Full Screen mode, restores sanity. So now everytme I see a freeze, mode switching comes to rescue.
Not sure if this will solve your issue, but worth a shot.
Rant: In general, I find this new WPF based product very falky and unstable than its predeccessors.
I have the same problem on IDE, some times the Return key is not working at all...
My solution is: CLEAN the project/solution.
BTW: CLEANing resolve also other unexpected behaviours after amendements on CSS or HTML.
I tried every other workaround here but nothing seemed to work, and the issue was only present in one solution but not another.
Disabling Resharper fixed it temporarily but it came back after re-enabling it which wasn't a viable long-term solution.
What worked for me was disabling all Resharper Extensions (Under Resharper -> Extension Manager). I was able to type again even after re-enabling all of them, so I'm unsure which extension specifically caused the issue, but that's another route to try for people who still have this issue.
I never had the problem until I installed plugins/extensions. Curious to know if anyone has had this problem without having any plugins/extensions installed. I don't know if they are the actual cause but since benefits of the plugins outweigh the occasional lockup, I have left them installed. BTW, I use the "closing/reopening of the window with the lockup" technique.
Using a source control (GIT, AKSVN)? If so, disable it, restart VS then enable it and open the solution again.
I'm having trouble finding any resource for adding ctrl-z undo capability to a Flex RichTextEditor control (a lack it apparently shares with other Flex text controls). I'm baffled that it's not in the native forms because it's such a fundamental capability, available in even standard browser text controls I believe.
Any mention of this issue on the Flex sites (there are several) conflict; one says the issue is "Closed" and the resolution is "External" (whatever that means).
Does anyone have any insight to offer? I've got an app the heavily requires extensive text editing. Flex in general works nicely, but this trivial lack is just about fatal, as anyone would imagine.
An example using the Flight Framework to easily implement undo/redo can be found here: http://www.xtyler.com/code/163
I've read elsewhere -- in fact, in the answers to one of my questions on SO -- that the issue is not going to be resolved in Flex 3. Which seems to be correct since we are in 3.2 or maybe even beyond that, and there's no undo in sight.
I was brave/stupid enough to implement an undo-redo in this component myself. At that time I was working on Windows. Now I'm on OSX and I realize just how non-cross-platform my solution is. The very statement of the problem (adding ctrl-z undo capability) is a large part of the problem (OSX has control AND this Apple key thing). Now I have to check how much work it would be to make the thing cross-platform... could be trivial.
By amazing coincidence, just today I've been thinking about NOT using the RichTextEditor but rather something external (FckEditor comes to mind) because the RTE leaves so much to be desired (hence I arrived at your question). I've worked with the RTE a ton and gotten it to do a lot of what I want, but I still wonder why they didn't "finish" this component...
Flex 3 controls do not natively support undo/redo. Here are a couple of libraries that may be of interest to you:
