# Legacy SIGNAL()/SLOT() connection syntax widely used

**Severity:** Low-Medium  
**Area:** Various  

## Description
Detected ~94 uses of old `SIGNAL()`/`SLOT()` syntax. While functional, this lacks compile-time checking and hampers modernization.

## Evidence
Automated scan found ~94 occurrences across the codebase.

## Steps to Reproduce
1. Grepped codebase for `connect(..., SIGNAL(` and `connect(..., SLOT(`.

## Expected Behavior
Use function-pointer (typed) `connect` syntax for compile-time safety and Qt6 best practices.

## Actual Behavior
Old macro-based syntax is still common.

## Suggested Fix / Next Steps
- Gradual refactor to typed connects, starting from central modules.
- Add CI check to prevent reintroduction.

Please don't copy-paste the output of code "analysis" from ChatGPT or another AI. It isn't actionable. Submitting merge requests to change these things would be helpful, but bug reports pointing them out isn't.
