Icons and symbols

While working in CLion, you can see various icons all around the UI. For most of them, you can get a tooltip description by hovering the mouse over an icon, for example:

File types
In the Project tree, files are marked with file type icons, for example Cidr base plugin icons file types cpp, Cidr base plugin icons file types h, Clion icons c make (see Recognized file types for the full list with corresponding symbols). The 'question mark' icon Icons file types unknown indicates that CLion could not recognize the file type.
Source files
Files marked with blue overlay badges Icons modules source root file layer are source files (for CMake projects, if a file icon does not have this overlay badge, it means that the file is not included in CMakeLists.txt).
VCS status indication
If VCS integration is enabled for the project, CLion uses colors to denote VCS file status in the Project tool window. For the colors meaning, refer to File status highlights.

Structure, Hierarchy, and Breadcrumbs Icons

Elements in Structure View, Call Hierarchy or Method Hierarchy can also have visibility indicators: private Icons nodes c private, protected Icons nodes c protected, or public Icons nodes c public.
