Types

type ClipItem added in v1.4.3 

type ClipItem struct {
	// contains filtered or unexported fields
}

ClipItem represents a single clip in a clip stack, denoted by a size and position.

func (*ClipItem) Intersect added in v1.4.3 

func (i *ClipItem) Intersect(p fyne.Position, s fyne.Size) *ClipItem

Intersect returns a new clip item that is the intersection of the requested parameters and this clip.

func (*ClipItem) Rect added in v1.4.3 

func (i *ClipItem) Rect() (fyne.Position, fyne.Size)

Rect returns the position and size parameters of the clip.

type ClipStack added in v1.4.3 

type ClipStack struct {
	// contains filtered or unexported fields
}

ClipStack keeps track of the areas that should be clipped when drawing a canvas. If no clips are present then adding one will be added as-is. Subsequent items pushed will be completely within the previous clip.

func (*ClipStack) Length added in v1.4.3 

func (c *ClipStack) Length() int

func (*ClipStack) Push added in v1.4.3 

func (c *ClipStack) Push(p fyne.Position, s fyne.Size) *ClipItem

Push a new clip onto this stack at position and size specified. The returned clip item is the result of calculating the intersection of the requested clip and it's parent.

func (*ClipStack) Top added in v1.4.3 

func (c *ClipStack) Top() *ClipItem

Top returns the current clip item - it will always be within the bounds of any parent clips.
