Features: - - Supports both raw locktime values and human-readable date formats - - Emits valueEdited signal when the locktime value is edited - - Provides threshold-based validation for locktime values - - Integrates with heir distribution workflows + - Multi-page navigation with Previous/Next buttons + - Automatic validation before proceeding to next page + - Progress tracking with visual indicators + - Customizable page flow and validation rules + - Integration with BalDialog base class for consistent styling - Behavior: - The class handles three types of locktime values: - 1. **Timestamps**: Raw integer values representing Unix timestamps - 2. **Day intervals**: Values ending with 'd' (e.g., '3d' = 3 days from now) - 3. **Year intervals**: Values ending with 'y' (e.g., '2y' = 2 years from now) - - Only these formats are valid: - - Examples: '1609459200', '3d', '2y' - - Invalid: 'invalid', '5m', '10x' - - The widget automatically converts day/year intervals to appropriate timestamps. + Usage: + The wizard follows a standard pattern: + 1. Initialize with a list of page constructors + 2. Each page is responsible for its own setup and validation + 3. The dialog manages navigation and state between pages + 4.
