Function addGridRow

pj_app/src/ui/Scene3DConfigPanel.cpp:84–91

Add one [label | field | trailing] row to a 3-column scene-control grid. Using a real grid column (not an in-cell spacer) keeps every field's right edge and the trailing eye/add button aligned across rows by construction. `trailing` may be null (column 2 stays reserved via setColumnMinimumWidth).

// edge and the trailing eye/add button aligned across rows by construction.
// `trailing` may be null (column 2 stays reserved via setColumnMinimumWidth).
void addGridRow(QGridLayout* grid, int& row, const QString& label, QWidget* field, QWidget* trailing = nullptr) {
  grid->addWidget(new QLabel(label + QStringLiteral(":")), row, 0);
  grid->addWidget(field, row, 1);
  if (trailing != nullptr) {
    grid->addWidget(trailing, row, 2);
  }
  ++row;
}
