Detailed Description

This class extracts and caches a subset of geometry and visualization information from a G4Volume wrapper:

• hierarchy (mother logical volume name)
• material name
• computed mass/volume/density (scaled to common units)
• visualization attributes (visibility, color, opacity)

It is intentionally small and UI-oriented: it acts as the "model" part of the widget, decoupled from Qt item instances.

Constructor & Destructor Documentation

G4Ttree_item()

G4Ttree_item::G4Ttree_item ( G4Volume * g4volume )

explicit

Parameters

g4volume

Pointer to the volume wrapper providing access to the physical/logical/solid volume objects and their attributes.

The constructor reads:

• The mother logical volume name (or a sentinel value for the world/root).
• The material name.
• Mass, volume, and density derived from the underlying geometry.
• Visualization color and alpha (opacity), and the visibility flag.

The stored "mother" name is used by GTree to reconstruct parent-child relationships when building the Qt tree.

set_color()

void G4Ttree_item::set_color ( QColor & c )

inline

Parameters

c	New RGB color.

This is used after a color or opacity change so that subsequent opacity changes can preserve RGB and update only alpha.

Definition at line 173 of file gtree.h.

set_opacity()

void G4Ttree_item::set_opacity ( double opacity )

inline

Parameters

opacity

New opacity (alpha) in [0,1].

Definition at line 179 of file gtree.h.

set_recursive()

void G4Ttree_item::set_recursive ( bool recursive )

inline

Parameters

recursive

New recursive state.

Definition at line 163 of file gtree.h.

system_from_v4name()

std::string G4Ttree_item::system_from_v4name ( std::string v4name )

static

Parameters

v4name

Full volume name including a system prefix separated by /.

Returns

The substring before the last /.

The returned system name is used as the top-level grouping node in the tree widget.

Definition at line 72 of file gtree.cc.

vname_from_v4name()

std::string G4Ttree_item::vname_from_v4name ( std::string v4name )

static

Parameters

v4name

Full volume name including a system prefix separated by /.

Returns

The substring after the last /.

This helper is used for display in the Qt tree so the user sees a compact name, while the full name remains stored as item metadata.
