Stage Sign Widgets

Stage-specific widgets injected into the SignProjectDialog based on which project stage the user is signing.

Architecture

SignProjectDialog uses lazy imports via _STAGE_WIDGET_MAP to load the correct widget for the current stage. All widgets extend BaseStageSignWidget, which defines the shared signal contract:

• validation_changed(bool) - controls whether the sign button is enabled
• sign_button_text_requested(str) - dynamically updates the sign button label

Widgets

Widget	Stage	Purpose
CPStageSignWidget	Vorplanung	Optional DP release with keyword validation ("Freigeben")
DPStageSignWidget	Detailplanung	Optional versioned release with minor/major bump and keyword validation ("Bestaetigen")
EPlanStageSignWidget	E-Planung	Placeholder (no additional options)
SoftwareStageSignWidget	Software	Placeholder (no additional options)
ComServStageSignWidget	IBWartung	Placeholder (no additional options)

Adding a New Stage Widget

1. Create a .ui file in ui/ and generate the pyui file in pyui/
2. Create a widget class extending BaseStageSignWidget
3. Override get_stage_data() to return stage-specific data
4. Emit validation_changed / sign_button_text_requested as needed
5. Register the widget in _STAGE_WIDGET_MAP in sign_project_dialog.py
6. Add a Stylesheets PathDef in startup_system/constants/paths.py
