Member Function Documentation

aborted()

void PatchChangeDrag::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.

bool PatchChangeDrag::allow_vertical_autoscroll ( ) const

inlinevirtual

Reimplemented from Drag.

Definition at line 728 of file editor_drag.h.

finished()

void PatchChangeDrag::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 PatchChangeDrag::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.

setup_pointer_offset()

void PatchChangeDrag::setup_pointer_offset ( )

virtual

Set up the _pointer_offset

Reimplemented from Drag.

y_movement_matters()

bool PatchChangeDrag::y_movement_matters ( ) const

inlinevirtual

Returns

true if y movement matters to this drag

Reimplemented from Drag.
