Member Function Documentation

aborted()

void NoteCreateDrag::aborted ( bool  m )

virtual

Called to abort a drag and return things to how they were before it started.

Parameters

m	true if some movement occurred, otherwise false.

Implements Drag.

active()

bool NoteCreateDrag::active ( Editing::MouseMode  m )

inlinevirtual

Parameters

m	Mouse mode.

Returns

true if this drag should happen in this mouse mode.

Reimplemented from Drag.

bool NoteCreateDrag::allow_vertical_autoscroll ( ) const

inlinevirtual

Reimplemented from Drag.

Definition at line 676 of file editor_drag.h.

finished()

void NoteCreateDrag::finished ( GdkEvent *  e, bool  m  )

virtual

Called when a drag has finished.

Parameters

e	Event describing the finish.
m	true if some movement occurred, otherwise false.

Implements Drag.

motion()

void NoteCreateDrag::motion ( GdkEvent *  e, bool  f  )

virtual

Called when a drag motion has occurred.

Parameters

e	Event describing the motion.
f	true if this is the first movement, otherwise false.

Implements Drag.

move_threshold()

std::pair<Temporal::timecnt_t,int> NoteCreateDrag::move_threshold ( ) const

inlineprivate
