This Delphi VCL application demonstrates multithreading with two threads competing to update a user interface containing progress bars and labels. The example highlights the use of critical sections to ensure thread safety during UI updates.
- Two Threads: Both threads attempt to update four progress bars simultaneously.
- Critical Sections: Uses
TCriticalSection
to prevent concurrent access to the UI. - Thread Synchronization: UI updates are managed with
TThread.Synchronize
to maintain thread safety.
- The application starts two threads when a button is clicked.
- Each thread updates the progress bars and a label, with each progress bar incrementing by 5 until reaching 100.
- Critical sections ensure that only one thread can update the UI at a time, preventing race conditions.
- Once both threads complete their tasks, the button is re-enabled.
