Member Function Documentation

displayOrder()

std::vector< int > ml::DragList::displayOrder ( int count ) const

inline

Row indices in display order: the dragged row sits at its drop slot; identity order otherwise. The owner draws a gap where slot's index == dragIndex().

Definition at line 80 of file DragList.h.

dragIndex()

int ml::DragList::dragIndex ( ) const

inline

Definition at line 94 of file DragList.h.

dropIndex()

int ml::DragList::dropIndex ( ) const

inline

Definition at line 95 of file DragList.h.

ghostY()

float ml::DragList::ghostY ( ) const

inline

Clamped Y for the floating ghost row (owner draws the dragged row here).

Definition at line 98 of file DragList.h.

isDragging()

bool ml::DragList::isDragging ( ) const

inline

Definition at line 93 of file DragList.h.

onReorder()

void ml::DragList::onReorder ( std::function< void(int from, int to)> cb )

inline

Definition at line 38 of file DragList.h.

onTap()

void ml::DragList::onTap ( std::function< void(int index)> cb )

inline

Definition at line 39 of file DragList.h.

setGeometry()

void ml::DragList::setGeometry ( float hitX0, float hitX1, float rowTop, int count, float rowHeight )

inline

Set the active list's geometry (all in the owner's local coords). hitX0..hitX1 is the horizontal band that starts a drag (exclude per-row buttons). count==0 disables dragging.

Definition at line 34 of file DragList.h.

update()

bool ml::DragList::update ( float localX, float localY, bool down, bool live )

inline

Feed once per frame with the cursor in the SAME local coords as setGeometry, the left-button state, and whether the list is currently interactive. Returns true when the visual state changed (owner should re-render).

Definition at line 44 of file DragList.h.
