Kdab Code Browser, Feature Tour

The Kdab Code Browser is a web-based code browser for your C, C++, Dart & Rust projects. You can read about it in our blog post or have a look at the browsable code of some of our favorite open source projects .

Semantic Coloration - Pick Your Theme

Semantic highlighting makes reading a piece of code easier as it helps differentiating what is what. You can quickly differentiate local variables from member variables or global variables. Virtual functions are in italic. You can see what is a macros, a typedef, or a type.

Different themes are available depending on your taste. Just pick one from the style combo box at the top right.

Navigation between functions

Clicking on a function brings you directly to the implementation. Just like normal URL, you can open it in a tab or new window and use the back button of your browser to come back where you came from.

Clicking on a variable brings you to the declaration of this variable

Tooltip containing all useful information about symbols

Hover over a symbol, and you can see its type, its documentation or where it is used.

Click on the "Show Uses" label to see the list of usages. You can visit each links to discover how it is used. (Hint: you can open them in different tabs.)

In the parentheses you can see the number of uses within each functions. And the letters inside the parentheses are telling how the variable is used:

The function signature contains the name of all the argument (useful to know what ' , false, true) ' means), in addition to the type of each argument and their default value if any.
For virtual functions, you can quickly go to the implementation of the inherited functions

For enum constant you can see the numerical value.

Macro expansions

The tool-tip of a macro shows its expansion.

Click on a macro to go to the corresponding #define .


Sometimes, when you are reading the code of a long functions, you may wonder in which function you actually are. You can see the current function in the header.

Qt support

The Qt SIGNAL and SLOT macros are well supported. The tooltip of a signal show where you connect to it or emit it.

Search for a file or for a function

Start typing the name of a file or the name of a function in the line edit at the top. Result will be auto-completed once you entered 4 characters. Jump directly to the file or that function.

Works also on the main page in codebrowser.dev

Show inheritance diagram

From the tooltip you can access a symbol detail page which shows the inheritance diagram of a class

Toggle line number

Inheritance graph of a class

If you wish to copy-paste code, you may want to hide the line numbers. Just click on the link to hide them or show them again.


expanded preprocessor macro

Clicking on an include brings you to that file

The tooltip of an #if/#elif/#else/#ifdef/#endif directives lets you jump to the matching directives

Usable links

Link to specific line numbers or to specific function or class within a page to show the code to people on a chat or web page.

Use it!
