Member Function Documentation

◆ setFill()

void juce::DrawableShape::setFill ( const FillType & newFill )

Sets a fill type for the path.

This colour is used to fill the path - if you don't want the path to be filled (e.g. if you're just drawing an outline), set this to a transparent colour.

See also: setPath, setStrokeFill

◆ getFill()

const FillType & juce::DrawableShape::getFill ( ) const

inlinenoexcept

Returns the current fill type.

See also: setFill

◆ setStrokeFill()

void juce::DrawableShape::setStrokeFill ( const FillType & newStrokeFill )

Sets the fill type with which the outline will be drawn.

See also: setFill

◆ getStrokeFill()

const FillType & juce::DrawableShape::getStrokeFill ( ) const

inlinenoexcept

Returns the current stroke fill.

See also: setStrokeFill

◆ setStrokeType()

void juce::DrawableShape::setStrokeType ( const PathStrokeType & newStrokeType )

Changes the properties of the outline that will be drawn around the path.

If the stroke has 0 thickness, no stroke will be drawn.

See also: setStrokeThickness, setStrokeColour

◆ setStrokeThickness()

void juce::DrawableShape::setStrokeThickness ( float newThickness )

Changes the stroke thickness.

This is a shortcut for calling setStrokeType.

◆ getStrokeType()

PathStrokeType juce::DrawableShape::getStrokeType ( ) const

inlinenoexcept

Returns the current outline style.

◆ setDashLengths()

void juce::DrawableShape::setDashLengths ( Span< const float > newDashLengths )

Provides a set of dash lengths to use for stroking the path.

◆ setDashOffset()

void juce::DrawableShape::setDashOffset ( float dashOffset )

Provides an offset on the rendering of the associated dash array.

◆ getDashLengths() [1/2]

Span< const float > juce::DrawableShape::getDashLengths ( ) const &

inline

Returns the set of dash lengths that the path is using.

◆ getDashLengths() [2/2]

Span< const float > juce::DrawableShape::getDashLengths ( ) const &&

delete

◆ getDrawableBoundsUntransformed()

Rectangle< float > juce::DrawableShape::getDrawableBoundsUntransformed ( ) const

overridevirtual

Returns the area that this drawable covers in its original coordinate system.

These bounds are not affected by setDrawableTransform().

See also: getDrawableBounds

Implements juce::Drawable.

◆ hitTest()

bool juce::DrawableShape::hitTest ( Point< float > ) const

overridevirtual

Tests whether a given point is inside the Drawable.

Implements juce::Drawable.

◆ replaceColour()

bool juce::DrawableShape::replaceColour	(	Colour	originalColour,
		Colour	replacementColour
	)

overridevirtual

Recursively replaces a colour that might be used for filling or stroking.

return true if any instances of this colour were found.

Reimplemented from juce::Drawable.

◆ getOutlineAsPath()

Path juce::DrawableShape::getOutlineAsPath ( ) const

overridevirtual

Creates a path that describes the outline of this drawable.

Implements juce::Drawable.

◆ pathChanged()

void juce::DrawableShape::pathChanged ( )

protected

Called when the cached path should be updated.

◆ strokeChanged()

void juce::DrawableShape::strokeChanged ( )

protected

Called when the cached stroke should be updated.

◆ isStrokeVisible()

bool juce::DrawableShape::isStrokeVisible ( ) const

protectednoexcept

True if there's a stroke with a non-zero thickness and non-transparent colour.
