Implementing Box Selection in CAA

When working with box selection functionality in CATIA's CAA framework, key components can be found in the following files:

  • CAADialogEngine.edu
  • CAADegGeoCommands.m
  • CAADegAnalysisNumericCmd.cpp

These files contain important implementation details for box selection mechanisms. Within the CATDialogAgent class, the SetBehavior() function plays a critical role in configuring multi-selection modes. Three specific behavior modes control the selection confirmation process:

Key Multi-Selection Modes in CATDlgEngMultiAcquisition

1. CATDlgEngMultiAcquisitionSelModes

Immediate Selection

  • Behavior: Selection is finalized immediately after drawing the box without requiring an explicit confirmation.
  • Use Case: Ideal for scenarios where instant selection is required without user confirmation.

2. CATDlgEngMultiAcquisitionCtrl

Confirmation Required

  • Behavior: Requires the user to click the OK button to confirm the selection after drawing the box.
  • Use Case: Best for workflows where explicit confirmation is necessary for accuracy.

3. CATDlgEngMultiAcquisitionUserCtrl

Dynamic Behavior Control

  • Behavior: Allows dynamic switching between the behaviors of CATDlgEngMultiAcquisitionCtrl and CATDlgEngMultiAcquisitionSelModes via programmatic control.
  • Use Case: Enables flexible UI customization where the confirmation requirement can be toggled based on application logic.
