Basically I have an image I'm trying to use as a splash screen. I set up the splash screen and even told it the location(":/Nuclear_Vortex_100_About.jpg") but when I run the program, all I see is a general window background "window"(no close box or any of the decoration, just a widget for lack of a better word) and no image on it.
I added the file (along with a bunch of other images I want to later load and use in the app) and they show up in the "Other Files" folder - ok so I figured since they're in the project, that they would be seen as resources if not source or headers. Do I need to add a special section to the PRO file or something in order to use the file? I'm about to just hard code an absolute path just to get it to work but I want a system independent way to get this done. I'm going to be paid for this project and I don't have much experience with the resource system in QT but it wasn't hard in Visual Studio and other C++ environments. As I see the splash screen show up, I know that part is working. The only thing I don't know for sure is that the file is not being found - that is I have not verified by using QFile and checking if it exists - I'll be doing that after I post this as it'll take some time to get a response or 2.
I have been searching for over a day and a half all over google and haven't found anything telling me what I'm doing wrong.
Thank you!
create resource file (.qrc) and add picture in it. It'll appear in resources section of your project. Then you can use it freely in your program.
Can some tell me what I have to do to straighten out Eclipse CDT's Type Hierarchy display?
I have C++ classes that I've refactored, changed their names, and moved around in the same file and/or into different files. When I click on "Open Type Hierarchy", Eclipse open up the Type Hierarchy window but it shows me the old names and duplicates of existing classes. Clicking on the old names vectors me to a random location in what was once (I'm assuming) the original source file. I have to click on the duplicates one after the other until I find one that vectors me to the correct location.
Is there a way to rebuild whatever needs to be rebuilt to get the Type Hierarchy window to show accurate classes and navigate properly?
Something I should point out is that all my project use their own makefile. i.e. Eclipse does not manage them. Does that make a difference?
Thanks
I have two cloned repositories of two very similar open-source projects, which I have been working on in different instances in Sublime Text 2 to arrive at my desired result. Code from both of these projects was used. I have been using Git as version control for my project, but have not included the original projects. Thus, I would like to be able to quickly compare the contents of two files of the original project and compare the differences between them and my project.
I was hoping that Sublime Text 2 would have a "Compare File" feature, but I can't seem to find anything related to it in the settings or online. A third-party ST2 package to accomplish this task would also work well. Is such a task possible to do within the ST2 text editor?
You can actually compare files natively right in Sublime Text.
Navigate to the folder containing them through Open Folder... or
in a project
Select the two files (ie, by holding Ctrl on
Windows or ⌘ on macOS) you want to compare in the sidebar
Right click and select the Diff files... option.
Compare Side-By-Side looks like the most convenient to me though it's not the most popular:
UPD: I need to add that this plugin can freeze ST while comparing big files. It is certainly not the best decision if you are going to compare large texts.
There are a number of diff plugins available via Package Control. I've used Sublimerge Pro, which worked well enough, but it's a commercial product (with an unlimited trial period) and closed-source, so you can't tweak it if you want to change something, or just look at its internals. FileDiffs is quite popular, judging by the number of installs, so you might want to try that one out.
UPDATE (Given the upvotes, I feel there is a need for a complete step-by-step explanation...)
In the Menu bar click on File->Open Folder...
Select a folder (the actual folder does not really matter, this step is just to make the FOLDERS sidebar available)
If there is no Side Bar shown yet, make it appear via View -> Side Bar -> Show Side Bar
Use this FOLDERS-titled Side Bar to navigate to the first file you want to compare.
Select it (click on it), hold down ctrl and select the second file.
Having two files selected, right click on one of the two and select Diff Files...
There should be a new Tab now showing the comparison.
Original short answer:
Note that:
The "Diff files" only appears with the "folders" sidebar (to open a folder: File->Open Folder) , not with "open files" sidebar.
UPDATE JAN 2018 - especially for Sublime/Mac
(This is very similar to Marty F's reply, but addresses some issues from previous responses, combines several different suggestions and discusses the critical distinction that gave me problems at first.)
I'm using Sublime Text 3 (build 3143) on Mac and have been trying for about 30 minutes to find this File Compare feature. I had used it before on Sublime/Mac without any problems, but this time, it was trickier. But, I finally figured it out.
The file format does not need to be UTF-8. I have successfully compared files that are UTF-8, ISO-8559-1, and Windows-1252.
There is no File > Open Folders on Sublime/Mac. Many instructions above start with "Select File > Open Folders," but that doesn't exist on Sublime/Mac.
File compare works on a Project basis. If you want to compare two files, they must be saved to disk and part of the current project.
Ways to open a project
If Sublime/Mac is not running or if it's running but no windows are open, drag a folder onto the Sublime app.
If Sublime/Mac is running, select "File > Open", navigate to the desired folder, don't select a file or folder and click "Open".
Add a folder to a project. If the files you want to compare are not part of the same hierarchy, first open the folder containing one of the files. Then, select "Project > Add Folder to Project", navigate to the folder you want and click "Open". You will now see two root-level folders in your sidebar.
The Sidebar must be visible. You can either "View > Side Bar > Show Side Bar" or use the shortcut, Command-K, Command-B.
Files must be closed (ie, saved) to compare. Single-clicking a file in the Side Bar does not open the file, but it does display it. You can tell if a file is open if it's listed in the "Open Files" section at the top of the Side Bar. Double-clicking a file or making a modification to a file will automatically change a file's status to "Open". In this case, be sure to close it before trying to compare.
Select files from the folder hierarchy. Standard Mac shorcut here, (single) click the first file, then Command-click the second file. When you select the first file, you'll see its contents, but it's not open. Then, when you Command-click the second file, you'll see its contents, but again, neither are open. You'll notice only one tab in the editing panel.
Control-click is not the same as right-click. This was the one that got me. I use my trackpad and often resort to Control-click as a right-click or secondary-click. This does not work for me. However, since I configured my trackpad in System Preferences to use the bottom-right corner of my trackpad as a right-click, that worked, displaying the contextual menu, with "Delete", "Reveal in Finder", and.... "Diff Files..."
Voilà!
UPDATE OCTOBER 2017
I never knew this feature existed in Sublime Text, but the interface appears to have changed slightly from the previous answer - at least on OS X. Here are the detailed steps I followed:
In the Menu Bar click File -> Open...
Navigate to the FOLDER that contains the files to be compared and with the FOLDER selected, click the Open button, this makes the FOLDERS sidebar appear
In the FOLDERS sidebar, click on the first file to be compared
Hold the Ctrl on Windows or ⌘ on OS X, and click the second file
With both files selected, right click on one and select Diff Files...
This opens a new tab showing the comparison. The first file in red, the second in green.
View - Layout and View - Groups will do in latest Sublime 3
eg:
Shift+Alt+2 --> creates 2 columns
Ctrl+2 --> move selected file to column 2
This is for side by side comparison.
For actual diff, there is the diff function other already mentioned.
Unfortunately, I can't find a way to make columns scroll at the same time, which would be a nice feature.
The Diff Option only appears if the files are in a folder that is part of a Project.
Than you can actually compare files natively right in Sublime Text.
Navigate to the folder containing them through Open Folder... or in a project
Select the two files (ie, by holding Ctrl on Windows or ⌘ on macOS) you want to compare in the sidebar
Right click and select the Diff files... option.
No one is talking about Linux but all above answers will work. Just use Ctrl to select more than one file. If you are looking to compare side by side, Meld is lovely.
There's a BeyondCompare plugin as well. It opens the 2 files in a BeyondCompare window. Pretty convenient to open files from the sublime window.
You will need BC3 installation present in the system.
After installing the plugin, you will have to provide the path to the installation.
Example:
{
//Define a custom path to beyond compare
"beyond_compare_path": "G:/Softwares/Beyond Compare 3/BCompare.exe"
}
I like to browse through my C++ projects in Notepad++. I use the SourceCookifier Plugin in order to easily jump in between definitions on large files. However, if I load a large C++ header file (around 30.000 lines), with a lot of #define and typedef declarations inside, it seems to hang and takes a long of time to load.
Does anyone know if there is any option one can set to make it faster or can this plugin generally not load so many definitions?
You can accelerate everything by throwing your project folder into the SourceCookifier panel while (and this is the important but badly documented part) pressing a modifier key (shift, ctrl or alt).
.. for importing INCLUDE files. But you have to additionally either
press the CTRL, SHIFT or ALT key while dropping a file or folder into
the treeview.
Or even smarter... separately only add your large define/typedef sources like described. It will result in a performance boost, since their symbols won't be listed in the tree view anymore, but SourceCookifier will still navigate you there, when hitting "Go To Definition" on one of their symbols somewhere else in the project.
I also sometimes use to add header files with several thousand defines to a SourceCookifier session. Without pressing ctrl-key it takes up to 5 mins per file, but with pressing ctrl-key it only takes 1 second!
EDIT/
Adding source files without pressing ctrl-key:
"Go To Definition" functionality? Yes.
Symbols shown in tree view as subnodes of source file node? Yes.
==> Not recommended for laaaarge source files.

I'm wondering if there is a command or plugin for eclipse that will take a header file of mine and auto-generate all of the method stubs into the CPP file from that header? I've googled and the lack of results would say not so, yet I can see in the CDT preferences under templates that there is an option to enable stub generation... but cannot find the command to use it. Thanks!
Okay so, after doing some more searching I found the solution myself. In the header file, right click in white space and select "Implement Method" and a window will appear showing a list of method declarations within the header. You can select some or all, then click "Finish" and be done with it or "Next" to follow the rest of the guided wizard process.
Edit
I've noticed at times when using this that the formatting of the generated stubs can be screwed up, or can screw up the formatting of your existing CPP file. If that does happen, just right click within the CPP file white space, click "Source" and select "Format" to correct the issue.
Another Edit
For some reason after all this time, there's been a bunch of activity of people trying to edit my answer to change it completely. All the edit is trying to communicate is that there is apparently a CTRL+3 shortcut to bring up the implement methods window.
I got a little lost in the Eclipse CDT and could not find the Implement Method selection described above. So for clarity sake I am posting this.
In Eclipse CDT Mars (and maybe previous versions):
Right click on white-space inside the .h or header file. Initial menu appears...
Click on Source->Implement Method...
Popup window appears; check methods (stubs) to create in .cpp / implementation file.
.
You could also check out http://www.lazycplusplus.com/. It is more powerful than generating method-stubs. It generates header and source files. I managed to integrate it in Visual Studio, so it runs on every build. Maybe you can do that in Eclipse, too.
Edit:
On my blog http://itmuckel.de I wrote an article about integrating Lazy C++ in Eclipse. It works really good. Here is the direct downloadlink of the tutorial: http://itmuckel.de/wp-content/uploads/2016/04/lzz_integration.pdf
It is written in german, but the screenshots of Eclipse show the english version. Besides that Google Translate will do a good job, too.
