Detailed Description

DBSelectView displays a tree of experiments and their system variations obtained from an SQLite database. Each system/variation row allows:

enabling/disabling that variation via a checkbox,
selecting a run number from a drop-down list,
viewing the number of matching geometry entries for the current selection,
seeing an availability indicator (green/red icon) driven by database counts.

The widget is designed to be used as a selection front-end for geometry reload:

get_gsystems() builds a SystemList reflecting the checked systems.
reload_geometry() triggers detector construction reload using that list.

Ownership model:

The widget owns its Qt child widgets through Qt parent-child relationships.
The widget owns and closes the sqlite3 database handle opened read-only.
The widget does not own the provided GDetectorConstruction pointer.

Important Qt note: GBase must appear after QWidget derivations; otherwise Qt's MOC expects a staticMetaObject.

Constructor & Destructor Documentation

◆ DBSelectView()

DBSelectView::DBSelectView	(	const std::shared_ptr< GOptions > &	gopts,
		GDetectorConstruction *	dc,
		QWidget *	parent = nullptr )

explicit

Construction steps (high-level):

Read the database location and default experiment from options.
Resolve the database path via a search in common locations and open it read-only.
Validate that the database contains a non-empty geometry table.
Create the UI, populate the model, and apply existing GSystem selections.

Parameters

gopts	Shared options used for database selection, default experiment, and UI mode.
dc	Detector construction instance used to reload geometry on user request.
parent	Optional parent widget for Qt ownership.

Definition at line 23 of file dbselectView.cc.

◆ ~DBSelectView()

DBSelectView::~DBSelectView ( )

inlineoverride

Closes the sqlite3 handle if it was successfully opened. Qt child widgets are cleaned up automatically by Qt parent ownership.

Member Function Documentation

◆ geometryAboutToReload

void DBSelectView::geometryAboutToReload ( )

signal

GUI containers use this signal to clear visualization state while the existing Geant4 geometry is still valid, avoiding stale trajectory/hit references after the reload.

◆ geometryReloaded

void DBSelectView::geometryReloaded ( )

signal

GUI containers use this signal to refresh pages whose models are built from detector construction state, such as the geometry volume tree.

◆ get_gsystems()

SystemList DBSelectView::get_gsystems ( )

The returned SystemList contains one GSystem for each checked system/variation item in the model. For each enabled row, the selected variation and run are taken from the corresponding model columns.

This function does not change the UI state; it is a pure extraction step.

Returns: A SystemList representing the currently checked systems and their selections.

Definition at line 546 of file dbselectView.cc.

◆ reload_geometry

void DBSelectView::reload_geometry ( )

slot

High-level behavior:

Build a SystemList from the model selections.
Invoke detector construction reload using that list.
Clear the modified state and refresh the UI.
