Cannot modify tab settings in Qt Creator

Question

I want tab to insert 2 spaces. All other solutions seem to be references an older version of Qt Creator.

Tools -> Options -> Text Editor -> Behaviour -> Tabs and Indentation

No 'Options' option exists in the dropdown menu.

Tools -> Options -> C++ -> Code Styles -> Edit

'Code Styles' does NOT exist in that path.

Qt Creator -> Preferences -> Behavior > Text Editor

This seems to be the appropriate place to modify settings for the whole IDE, but they don't seem to be getting saved to the project.

Qt 5.2.1

Answer 1

There are "Project Settings" that have precedence over the global settings under Tools -> Options -> Text Editor -> ...
These settings can be found in the Projects "UI section" and you have to define a custom "Code Style" for this:

1. Switch to "Projects" (Ctrl-5)
2. From the column to the right select "Code Style" (not "Editor") under "Project Settings"
3. Click "Edit..."
4. Click "Copy Built-in Code Style"
5. On the "General" tab adjust tab settings
