Types

type BitSet

type BitSet []uint64

BitSet is a set of bits that can be set, cleared and queried.

func (*BitSet) IsSet

func (s *BitSet) IsSet(i uint) bool

IsSet returns true if the given bit is set, false if it is cleared.

func (*BitSet) Set

func (s *BitSet) Set(i uint)

Set ensures that the given bit is set in the BitSet.

func (*BitSet) Unset

func (s *BitSet) Unset(i uint)

Unset ensures that the given bit is cleared (not set) in the BitSet.

type HSpace

type HSpace struct {
	widget.BaseWidget

	Width float32
}

func NewHSpace

func NewHSpace(w float32) *HSpace

func (*HSpace) CreateRenderer

func (h *HSpace) CreateRenderer() fyne.WidgetRenderer

func (*HSpace) MinSize

func (h *HSpace) MinSize() fyne.Size

type ListSelectionManager

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

func NewListSelectionManager

func NewListSelectionManager(lenFn func() int) ListSelectionManager

func (*ListSelectionManager) AreAllSelected

func (l *ListSelectionManager) AreAllSelected() bool

func (*ListSelectionManager) GetSelection

func (l *ListSelectionManager) GetSelection() []int

func (*ListSelectionManager) IsSelected

func (l *ListSelectionManager) IsSelected(row int) bool

func (*ListSelectionManager) Select

func (l *ListSelectionManager) Select(row int)

If the given row is not selected, reset the selection and select only the given row.

func (*ListSelectionManager) SelectAddOrRemove

func (l *ListSelectionManager) SelectAddOrRemove(row int)

If it is not selected, add the given row to the selection. If it is selected, unselet it.

func (*ListSelectionManager) SelectAll

func (l *ListSelectionManager) SelectAll()

func (*ListSelectionManager) SelectRange

func (l *ListSelectionManager) SelectRange(row int)

Select a range between the given row and the furthest-down row that is currently selected (which may be above the given row) Note: this is modeled after what, as far as I can tell, is Gmail's selection behavior

func (*ListSelectionManager) UnselectAll

func (l *ListSelectionManager) UnselectAll()
