Constructor & Destructor Documentation

FlowWidget()

FlowWidget::FlowWidget	(	QWidget *	parent,
		Qt::Orientation	orientation,
		Qt::ScrollBarPolicy	horizontalPolicy,
		Qt::ScrollBarPolicy	verticalPolicy )

Constructs a FlowWidget.

When both scroll policies are Qt::ScrollBarAlwaysOff the scroll area is omitted entirely and the container is placed directly in the main layout.

Parameters

parent	Parent widget.
_flowDirection	Qt::Horizontal for row-wrapping, Qt::Vertical for column-wrapping.
horizontalPolicy	Horizontal scroll-bar policy.
verticalPolicy	Vertical scroll-bar policy.

Member Function Documentation

addWidget()

void FlowWidget::addWidget

(

QWidget *

widget_to_add

)

const

Adds a widget to the flow layout within the FlowWidget.

Parameters

widget_to_add

The widget to add to the flow layout.

Here is the caller graph for this function:

clearLayout()

void FlowWidget::clearLayout

(

)

Removes all widgets from the flow layout and deletes them.

If the layout pointer has somehow been lost it is recreated before returning.

count()

int FlowWidget::count ( ) const

insertWidgetAtIndex()

void FlowWidget::insertWidgetAtIndex	(	QWidget *	toInsert,
		int	index )

itemAt()

QLayoutItem * FlowWidget::itemAt ( int index ) const

nodiscard

removeWidget()

void FlowWidget::removeWidget

(

QWidget *

widgetToRemove

)

const

Here is the caller graph for this function:

resizeEvent()

void FlowWidget::resizeEvent ( QResizeEvent * event )

overrideprotected

Marks the flow layout as dirty so Qt recomputes item positions.

We do NOT call adjustSize() or activate() here:

• adjustSize() would freeze geometry by calling setFixedSize internally.
• activate() called inside a resize event can cause synchronous re-entrancy. Qt automatically calls setGeometry on the layout after a resize, so simply invalidating is sufficient.

setMinimumSizeToMaxSizeHint

void FlowWidget::setMinimumSizeToMaxSizeHint ( )

slot

Sets every child widget's minimum size to the largest sizeHint in the layout.

Useful for toolbars or button bars where all items should be the same size.

Here is the caller graph for this function:

setSpacing

void FlowWidget::setSpacing ( int hSpacing, int vSpacing )

slot
