Detailed Description

The border form element is a placeholder form element that can be used to make Anchor Layouts stretchable.

Use a single BorderFormElement in anchor constraints to attach other elements to the different edges of the item. The size of the BorderFormElement is automatically set by the Anchor Layout to match the size of the item.

Using a BorderFormElement in an Anchor Layout will automatically make the Anchor Layout stretchable.

Member Function Documentation

◆ clone()

BorderFormElement * Visualization::BorderFormElement::clone ( ) const

overridevirtual

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

Implements Visualization::FormElement.

◆ computeSize()

void Visualization::BorderFormElement::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::BorderFormElement::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=()

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

delete

◆ sizeDependsOnParent()

bool Visualization::BorderFormElement::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.
