When comparing IntelliJ IDEA vs Qt Creator, the Slant community recommends IntelliJ IDEA for most people. In the question“What are the best IDEs for Android development?” IntelliJ IDEA is ranked 1st while Qt Creator is ranked 10th. The most important reason people chose IntelliJ IDEA is:
IDEA places an emphasis in safe refactoring, offering a [variety of features](https://www.jetbrains.com/idea/features/refactoring.html) to make this possible for a variety of languages. These features include safe delete, type migration and replacing method code duplicates.
Ranked in these QuestionsQuestion Ranking
Pro Smart refactorings
IDEA places an emphasis in safe refactoring, offering a variety of features to make this possible for a variety of languages.
These features include safe delete, type migration and replacing method code duplicates.
Pro Fast and smart contextual assistance
Uses a fast indexing technique to provide contextual hints (auto-completion, available object members, import suggestions).
On-the-fly code analysis to detect errors and propose refactorization.
Pro Android support, JavaEE support, etc
A very complete development environment support.
Pro Support for many languages
IntelliJ supports many languages besides Java, some of these are: golang, Scala, Clojure, Groovy, Bash, etc.
Pro Lots of plugins
Many plugins are available for almost any task a developer may need to cover. Plugins are developed by Jetbrains themselves or by 3rd parties through the SDK available for writing them.
Pro Stable and robust
IntelliJ IDEA hardly ever crashes or has any issues that plague other Java IDEs like file corruption or slowness.
Pro Intuitive and slick UI
IDEA has a clean, intuitive interface with some customization available (such as the Darcula theme).
Pro Free version available
There is a free community edition (open source) and an ultimate edition, which you can compare here.
The ultimate edition is available for free for one year for students but must be registered through an .edu e-mail account.
Pro Very powerful debugger
With ability to step into a certain part of a large method invocation (Shift+F7), drop frame, executing code snippets, showing method return values, etc.
Pro Many convenient features
These simplify the daily work, e.g. copy/cut a whole line without the need to select it.
Pro Gradle support
Pro Clear and detailed documentation
The documentation is exhaustive, easy to navigate, and clearly worded.
Pro Built-in Git support
Pro Embedded database support
Creating an embedded database, running SQL script in a dedicated terminal, viewing tables and their contents, and creating a connection to an in-memory or embedded database is fully supported.
Pro Prices are not bad
I pay $24 a month and i have access to all jetbrain peoducts , so i use their many tools , i tried many others like netbeans , eclipse , etc , they re good but intelij is on the space and the sky is the limit . Been using it for 5 years and i cant tell i got frustrated using .it
Pro Great syntax highlighting and auto-completion
Qt Creator has a code model which basically has the same information as the compiler. So it can do really nice syntax highlighting (e.g. of virtual methods or local variables) as well as provide great code completion.
Pro Fast and fully keyboard-navigatable
Responsive UI, no need to use the mouse for the power users.
Pro Integrates well with non-IDE workflows
Qt Creator uses normal .pro-files, CMakeLists.txt, Makefiles.am, etc. for its projects and rarely needs special configuration for projects.
Projects can be built on the command line as usual.
Pro Supports CMake
Pro Much space dedicated to the code
Small and beautiful UI, almost all the space is dedicated to the text with hardly and toolbars. Can actually be used on a 1024x768 pixel screen.
Pro Very responsive when compared to similar software
Pro Built-in Qt GUI editor
Allows for the creation of a window based UI in a graphical editor, no code required to build the UI.
Con Slow startup
Startup can be slow depending on system configuration.
Con Uses a lot of RAM
Con Standard hotkeys behave differently
Seems like hotkeys assignment in Idea has no logical consistency.
Like «F3» is usually next match, «Ctrl+W» - close tab, etc — they map to some different action by default.
There is a good effort in making the IDE friendly for immigrants from other products: there are options to use hotkeys from Eclipse, and even emacs. But these mappings are very incomplete. And help pages do not take this remapping into account, rather mentioning the standard hotkeys.
So, people coming from other IDEs/editors are doomed to using mouse and context menus (which are rather big and complex).
Con Bugs are not solved as often as they should
They are more interested in adding new features or issuing new versions than solving bugs.
Con Cannot open multiple projects in the same window
Con Built with closed source components
The version with full features is not opensource. Parts of the code are under apache licence though.
Con Lack of plugins
IntelliJ supports a very small amount of plugins. Although these are 'quality approved', many features are missing and can't be implemented because of that.
Con Poor refactoring
QtCreator has lack of refactoring features. It's not even close to Resharper++ or CLion.
Qt Creator is focused on being an IDE for Qt, as a general purpose IDE it performs quite well, but there are areas which are lacking such as project file support (support for generic/CMake projects lags behind Qt projects).
Con Poor multi-window mode support
While multiple windows are supported, many operations will activate in the primary window (debug, goto-line... etc).
