Full Screen Button CWC

Full screen btn is a WinCC Unified Custom Web Control that triggers reliable fullscreen enter/exit behavior using a dedicated local helper backend.

Repository Contents

• deploy_cwc.bat: builds and copies the CWC ZIP to the WinCC CustomControls folder
• {B5EE6DEF-00EB-4880-AC1E-39A6AF506363}/: CWC manifest and frontend assets
• fullscreen_local_server.py: primary local fullscreen helper
• fullscreen_local_server.ps1: legacy helper variant
• start_fullscreen_local_server.bat: starts and validates the local helper
• _ModuleTemplate_extract/: companion/module packaging source
• FullscreenModule.zip: built module package

What It Does

• enters fullscreen through a local helper
• exits fullscreen through a local helper
• falls back to browser fullscreen APIs if the helper is unavailable
• supports explicit enter, exit, and toggle behavior

Local Development

1. Start the helper with start_fullscreen_local_server.bat
2. Deploy the CWC with deploy_cwc.bat
3. Test the helper health endpoint at http://127.0.0.1:8767/health

Notes

• the Python helper is the active backend
• the packaged module is intended for deployment alongside the CWC
• the PowerShell helper is retained only as an older implementation
