◆ effectiveAlignment()

Qt::Alignment QGridLayoutEngine::effectiveAlignment ( const QGridLayoutItem * layoutItem) const

Definition at line 933 of file qgridlayoutengine.cpp.

◆ effectiveFirstRow()

int QGridLayoutEngine::effectiveLastRow ( Qt::Orientation orientation = Qt::Vertical) const

Definition at line 799 of file qgridlayoutengine.cpp.

◆ ensureDynamicConstraint()

bool QGridLayoutEngine::ensureDynamicConstraint ( ) const

returns false if the layout has contradicting constraints (i.e. some items with a horizontal constraint and other items with a vertical constraint)

Definition at line 1616 of file qgridlayoutengine.cpp.

◆ hasDynamicConstraint()

bool QGridLayoutEngine::hasDynamicConstraint ( ) const

Definition at line 1639 of file qgridlayoutengine.cpp.

◆ insertItem()

void QGridLayoutEngine::insertItem ( QGridLayoutItem * item,
int index )

The index is only used by QGraphicsLinearLayout to ensure that itemAt() reflects the order of visual arrangement. Strictly speaking it does not have to, but most people expect it to. (And if it didn't we would have to add itemArrangedAt(int index) or something..)
