Is there anyway to comment certain sections of my .pro file (Qt project)?
In my case I want to comment specific parts that do not apply to the platform I'm currently targeting.
Found this now: http://doc.qt.io/qt-4.8/qmake-project-files.html.
You can comment lines by using a # symbol.
In the .pro file, # before any line or statement indicates a comment.
you have to place a # at the begin of each line.
I think Silva is looking for something like this in .pro file:
if(false) {
...
your block
...
}
This is the programmatic way to do commenting, and you have control of it. Similar approaches may available for other test functions.
If using QtCreator, highlight the section you wish to comment out, then right click for context menu and select 'Toggle Comment Selection'. This is good for large blocks code to comment out.

Im using atom.io for some time now and really like it. there is just one thing im missing. I used to use brackets and sublime before and they both had a feature where you could create the basic structure of a html documents by just typing html.
this would just set the html, head and body tag. created the charset meta, title and link to css file.
I create a lot of html files a day so it would be really helpfull if I know the shortcode or the package which supports this!
You're looking for autocomplete-snippets.
Simply type html and press Enter
Here's a terrible GIF to prove it:
There is a nice Plugin, called emmet: https://atom.io/packages/emmet
When you got that, you just have to type ! -> tab in an empty document. You get pretty much the same result as #hatchet GIF.
If you have disabled the autocomplete functionality mentioned in the currently accepted answer, or want more flexibility than that allows, there is a file-templates package:
https://atom.io/packages/file-templates
Here are some basic instructions.
To install the package: edit->preferences->install->file-templates.
To save the template: packages->new template from this file.
To open a new file with that template, just hit ctrl-alt-n and
select it.
Make sure your file has .html added on the end of its name.
Then go back into Atom, type HTML, and press enter. Your boilerplate should appear. Solved my problem instantly!
If we install Emmet package we are not getting the boiler plate code. So I disabled emmet and it is working fine for me.
!tab is the command u seek. But it won't work unless you create a file and save it with the html extension...
So go create a new file in the directory u want, call it index.html and now go type !tab
It should work 100%, if not be sure u have emmet installed.
I am trying to modify a CSS file using Sublime Text 2, however, all the code is presented in one linebreaks with no line break whatsoever.
What can I do to change that into readable code?
Try using Code Beautifier. You input the code and it formats it for you. There are many other sites like this one so check around and see which one you like best.
If you want to use a Sublime Text plugin, try CSS Format by mutian.
EDIT: As said by Imran Bughio, CSS Beautify is another site like Code Beautifier.
EDIT 2: As noted by Beginner, CSSLisible is another option.
Go to this site CSSLISIBLE. paste your css code and click Clean this code button..
Only one error to go until I get to use this for my research!
Warning: Z-order assignment: " is not a valid widget.
FILE: qvvideoreaderblockwidget.ui
There's no line number that came with it. I tried finding but, failed to see an open-ended part.
What should I do to correctly compile this library?
Edit the ui file outside of Qt Creator. Delete the rows with 'zorder' tags. Then open in Qt Creator and compile again. It worked for me then perfectly, the warning did not appear any more.
OK, I had this, and it irked me too. I don't know what happened to cause this, but it is not serious. I suppose that breaking and remaking all the layouts might fix it. Other frameworks tend toward a lot of warnings, but tho I'm new to Qt, not a one yet. I went in another editor, and removed a line that said (as best I can remember):
<z-order>verticalSpacer</z-order>
which was among a lot of other lines which also were z-order tags. I deleted the line with this tag, and rebuilt all. Problem gone. Interestingly enough, all of the z-order tags had vanished from my file when I looked at it next. It must be a bug, but evidently one of little consequence; except those who hate to see the serene beauty of Qt spoiled.
Does the ui-file qvvideoreaderblockwidget.ui contain "Promoted widgets"? If so, use the "Promoted widgets" dialog of the (Qt4-) designer for ensuring that the header of the promoted widget-class is declared as "global include".
In case the custom widget class is named "MyWidget" and the header is named "mywidget.h" and the member widget shall be named "myWidget", the uic will generate the code of the ui-class as follows:
#include <mywidget.h>
class qvvideoreaderblockwidget
{
public:
MyWidget* myWidget;
// ...
};
It happened to me when I deleted a fairly large chunk of stuff in the designer. Investigation showed that the designer had failed to remove a zorder tag relating to the widget I deleted (which, incidentally contained a bunch of other widgets).
Deleting the line as suggested cleared the problem. If you do have a load of zorder tags you probably need to be careful to just delete the one that relates to the deleted item.
I had the same problem, and deleting the .exe file from the output folder (debug or release) before run/compile the source, solved the problem.
This problem arises due to a (presently) unfixed bug in Qt Creator's undo / delete mechanism.
The solution until the bug is fixed is to:
Close the .ui file in Qt Designer
Open the .ui file in an external editor
Delete the <zorder> line(s) that apply to the element with the problem. For example:
<zorder>groupBox_2</zorder>
Save the file
Re-open the file in Qt Designer
Re-compile in Qt
I couldn't find a way to put a bookmark inside the code in XCode 4. I know about the #pragma mark thing but it's not what I'm looking for. What I need is something that I can put and remove with a mouse click and navigate amongst with next and previous, like in VS.
Is there anything that I'm missing?
Bookmarks seem to have gone the way of the dinosaur in Xcode 4. This wouldn't have been so bad had the jump-to-bookmark popup above the editor in previous versions not also disappeared. The best replacement currently seems to be to use breakpoints (disabled individually, of course) and navigate with the Breakpoint Navigator.
Shortcut to breakpoints is Cmd + 8. Once there use arrow keys
File a bug report at http://bugreporter.apple.com if you feel something like this should be brought back.
Write below comment in your source file that you want bookmarked.
//<##>
And you can navigate to next / previous with: '^/' or '^?'
<##> means "placeholder of code snippet"
^/ means "jump to next placeholder"
^? means "jump to previous placeholder"
thanks
Another option, if anyone is still interested. The following directives will both produce a compiler warning that you can use as a bookmark:
#pragma message "<# message #>"
or
#warning <# message #>
If you want to place bookmarks using your mouse: create a code snippet with one of the 2 directives above. Drag & drop it to the line in your source file that you want bookmarked.
Navigate to next/previous with: Cmd-' and Cmd-Shift-'
In Xcode 4.4, if you leave a comment with this format:
// TODO: Your text here
it will be added as a listing in the jump bar alongside the list of methods in your current file, and then you can jump straight to that comment from that menu.
The simplest technique is to use a comment prepended by // TODO and then search, which allows you to jump through the issues from the navigator. Pretty hard to beat that technique.
I personally don't like using break points for bookmarks because it is not easy to enter notes. I use breakpoints as breakpoints, and prefer not to mix them up with bookmarks.
Anyhow, if you want to get a bit fancier you could get xcode to generate warnings // TODO: some message or // FIXME: some message that can be navigated in the issue navigator. I took the instructions below from this site:
Instructions
Head over to your project's item in the Project Navigator (usually at the very top)
Find your target in the list of targets on the left, select it
Head over to the "Build Phases" tab.
Click the "Add Build Phase" in the bottom right of this screen.
In the editor that appears insert the bash script shown below.
Now just build and you'll see all your //TODO: and //FIXME: comments have become warnings. I love this technique, it might not be right for everyone, but hope it helps someone.
Bash Script For "Run Script" Build Phase
KEYWORDS="TODO:|FIXME:|\?\?\?:|!!!:"
find "${SRCROOT}" ( -name ".h" -or -name ".m" ) -print0 | xargs -0 egrep --with-filename --line-number --only-matching "($KEYWORDS).*\$" | perl -p -e "s/($KEYWORDS)/ warning: \$1/"
You'll also be able to click on each of the warnings in the issue navigator to go right to the file and point in your code where you left the original //TODO: or //FIXME:
Extra pro tip: Make sure you're using phrases to describe your //TODO: comments like //TODO: Handle this error gracefully, and things like that. The phrases will show up in the issues list beside each warning.
Credit for the little tidbit should go to "Tim" on the Cocos2D forums, (found after Googling for a bit), I believe his solution originally was intended for Xcode 3 and didn't work if you had spaces in your path name, my script here doesn't have those restrictions, still he should get full credit here's his original post.
Like npellow's answer to this question of mine, appCode by JetBrains has also made this possible. So, this may be another reason to use appCode instead of Xcode4, except that it won't be free later in time.
My method:
type in grammar error code in the previous line.....
After changing something in other place, I can go back to the previous place because the grammer error line will show a red line in the right side scroll bar. It indicate the place.
It is not elegant but unless there is a bookmark feature, this is the way i am using at the moment
You can install an Xcode plugin called "XBookmark".
This plugin provide features below :
Toggle Bookmark
Show Bookmarks
Next Bookmark
Previous Bookmark
How to install XBookmark:
Install Alcatraz.
Search XBookmark from Window->Package Manager and click Install.
Restart Xcode.
Now, you can see menus about bookmarks in the Edit Menu.
PS : This plugin is open source.
In Qt 4.6 QTestLib supports the command-line argument "-chart" (but this is undocumented).
A report.html is created, however neither Firefox 3.6 nor IE8 are able to display anything but the headline "Test". When I look into the html-file it has some JavaScript stuff and test results, so there should be something to display.
As -chart is undocumented, I'm not sure I use it the correct way.
Any hints?
Thanks.
Try using it in combination with the -xml option. I suspect the Javascript reads in an XML file to generate the chart, not sure though.
Also, it might have something to do with this Qt labs blog post: http://labs.trolltech.com/blogs/2008/12/05/qtestlib-now-with-nice-graphs-pointing-upwards
How about looking into the produced HTML file with a text editor?
Other than that, reading the source code of QTest might help.
I assume it's some semi complete experimental feature.
