Create Declaration / Definition

What: Lets you immediately generate the declaration or definition of a function.

When: You have a function that needs a declaration, or vice-versa.

Why: You could manually create the declaration/definition, but this will create it automatically, creating the header/code file if necessary.

How:

1. Place your text or mouse cursor over the function for which you want to create the declaration or definition.

   

2. Next, do one of the following:

   • Keyboard
     • Press Ctrl+. to trigger the Quick Actions and Refactorings menu and select Create Declaration / Definition from the context menu.
   • Mouse
     • Right-click and select the Quick Actions and Refactorings menu and select Create Declaration / Definition from the context menu.

3. The function's declaration/definition will be created in the source or header file, which you'll see in a popup preview window. If the source or header file doesn't exist, it will also be created and placed in the project.
