Member Function Documentation

◆ clone()

ShapeFormElement * Visualization::ShapeFormElement::clone ( ) const

overridevirtual

Copy this element and all its children into a new element tree.

Implements Visualization::FormElement.

◆ computeSize()

void Visualization::ShapeFormElement::computeSize	(	Item *	item,
		int	availableWidth,
		int	availableHeight
	)

overridevirtual

Method called inside the item's updateGeometry method to compute it's size and position it's child elements.

The arguments availableWidth and availableHeight are similar to those of Item::updateGeometry. If they are zero, the form element calculates its minimum size, if it they are bigger, the element tries to stretch/grow to this size, but not further.

Implements Visualization::FormElement.

◆ isEmpty()

bool Visualization::ShapeFormElement::isEmpty ( const Item * item ) const

overridevirtual

Method called inside the item's isEmpty method, and by some layout form elements.

It recursively determines whether the form element is empty for the specified item.

Reimplemented from Visualization::FormElement.

◆ operator=()

ShapeFormElement& Visualization::ShapeFormElement::operator= ( const ShapeFormElement & )

delete

◆ shapeElements()

QList< FormElement * > Visualization::ShapeFormElement::shapeElements ( )

overridevirtual

Returns the list of shape elements inside this form element.

Recursively collects the shape elements from the element's children. Method is called once after the static initialization of the visualization item type.

Reimplemented from Visualization::FormElement.

◆ sizeDependsOnParent()

bool Visualization::ShapeFormElement::sizeDependsOnParent ( const Item * item ) const

overridevirtual

Method called inside the item's sizeDependsOnParent method, and by some layout form elements.

If the form element returns true it can be, that computeSize is called on it a second time with non-zero availableWidth and availableHeight.

Implements Visualization::FormElement.
