Detailed Description

A drawable object which acts as a container for a set of other Drawables.

Note that although this is a Component, it takes ownership of its child components and will delete them, so that you can use it as a self-contained graphic object. The intention is that you should not add your own components to it, only add other Drawable objects.

Constructor & Destructor Documentation

DrawableComposite() [1/2]

juce::DrawableComposite::DrawableComposite

(

)

Creates a composite Drawable.

DrawableComposite() [2/2]

juce::DrawableComposite::DrawableComposite

(

const DrawableComposite &

other

)

Creates a copy of a DrawableComposite.

~DrawableComposite()

juce::DrawableComposite::~DrawableComposite ( )

override

Destructor.

Member Function Documentation

childBoundsChanged()

void juce::DrawableComposite::childBoundsChanged ( Component * child )

overridevirtual

Called when one of this component's children is moved or resized.

If the parent wants to know about changes to its immediate children (not to children of its children), this is the method to override.

See also

moved, resized, parentSizeChanged

Reimplemented from juce::Component.

childrenChanged()

void juce::DrawableComposite::childrenChanged ( )

overridevirtual

Subclasses can use this callback to be told when children are added or removed, or when their z-order changes.

See also

parentHierarchyChanged, ComponentListener::componentChildrenChanged

Reimplemented from juce::Component.

createCopy()

std::unique_ptr< Drawable > juce::DrawableComposite::createCopy ( ) const

overridevirtual

Creates a deep copy of this Drawable object.

Use this to create a new copy of this and any sub-objects in the tree.

Implements juce::Drawable.

getBoundingBox()

Parallelogram< float > juce::DrawableComposite::getBoundingBox ( ) const

inlinenoexcept

Returns the parallelogram that defines the target position of the content rectangle when the drawable is rendered.

See also

setBoundingBox

getContentArea()

Rectangle< float > juce::DrawableComposite::getContentArea ( ) const

inlinenoexcept

Returns the main content rectangle.

See also

contentLeftMarkerName, contentRightMarkerName, contentTopMarkerName, contentBottomMarkerName

getDrawableBounds()

Rectangle< float > juce::DrawableComposite::getDrawableBounds ( ) const

overridevirtual

Returns the area that this drawable covers. The result is expressed in this drawable's own coordinate space, and does not take into account any transforms that may be applied to the component.

Implements juce::Drawable.

getOutlineAsPath()

Path juce::DrawableComposite::getOutlineAsPath ( ) const

overridevirtual

Creates a path that describes the outline of this drawable.

Implements juce::Drawable.

operator=()

DrawableComposite & juce::DrawableComposite::operator= ( const DrawableComposite & )

private

parentHierarchyChanged()

void juce::DrawableComposite::parentHierarchyChanged ( )

overridevirtual

Called to indicate that the component's parents have changed.

When a component is added or removed from its parent, this method will be called on all of its children (recursively - so all children of its children will also be called as well).

Subclasses can override this if they need to react to this in some way.

See also

getParentComponent, isShowing, ComponentListener::componentParentHierarchyChanged

Reimplemented from juce::Drawable.

resetBoundingBoxToContentArea()

void juce::DrawableComposite::resetBoundingBoxToContentArea

(

)

Changes the bounding box transform to match the content area, so that any sub-items will be drawn at their untransformed positions.

resetContentAreaAndBoundingBoxToFitChildren()

void juce::DrawableComposite::resetContentAreaAndBoundingBoxToFitChildren

(

)

Resets the content area and the bounding transform to fit around the area occupied by the child components.

setBoundingBox() [1/2]

void juce::DrawableComposite::setBoundingBox

(

Parallelogram< float >

newBoundingBox

)

Sets the parallelogram that defines the target position of the content rectangle when the drawable is rendered.

See also

setContentArea

setBoundingBox() [2/2]

void juce::DrawableComposite::setBoundingBox

(

Rectangle< float >

newBoundingBox

)

Sets the rectangle that defines the target position of the content rectangle when the drawable is rendered.

See also

setContentArea

setContentArea()

void juce::DrawableComposite::setContentArea

(

Rectangle< float >

newArea

)

Changes the main content area.
