Member Function Documentation

close

bool lmms::gui::TrackView::close ( )

virtualslot

Close this track View.

Reimplemented in lmms::gui::PatternTrackView.

createClipView

void lmms::gui::TrackView::createClipView ( lmms::Clip * clip )

privateslot

Create a Clip View in this track View.

Parameters

clip	The Clip to create the view for.

createMixerMenu()

QMenu * lmms::gui::TrackView::createMixerMenu ( QString title, QString newMixerLabel )

virtual

Create a menu for assigning/creating channels for this track.

Currently instrument track and sample track supports it

Reimplemented in lmms::gui::InstrumentTrackView, and lmms::gui::SampleTrackView.

dragEnterEvent()

void lmms::gui::TrackView::dragEnterEvent ( QDragEnterEvent * dee )

overrideprotected

Start a drag event on this track View.

Parameters

dee	The DragEnterEvent to start.

dropEvent()

void lmms::gui::TrackView::dropEvent ( QDropEvent * de )

overrideprotected

Accept a drop event on this track View.

We only accept drop events that are of the same type as this track. If so, we decode the data from the drop event by just feeding it back into the engine as a state.

Parameters

de	The DropEvent to handle.

getActivityIndicator()

virtual FadeButton * lmms::gui::TrackView::getActivityIndicator ( )

inlineprivatevirtual

Reimplemented in lmms::gui::InstrumentTrackView, and lmms::gui::SampleTrackView.

getTrack() [1/2]

isMovingTrack()

bool lmms::gui::TrackView::isMovingTrack ( ) const

inline

loadSettings()

void lmms::gui::TrackView::loadSettings ( const QDomElement & element )

inlineoverrideprotectedvirtual

Implements lmms::SerializingObject.

modelChanged()

void lmms::gui::TrackView::modelChanged ( )

overrideprotectedvirtual

Register that the model of this track View has changed.

Reimplemented from lmms::gui::ModelView.

mouseMoveEvent()

void lmms::gui::TrackView::mouseMoveEvent ( QMouseEvent * me )

overrideprotected

Handle a mouse move event on this track View.

If this track container supports rubber band selection, let the widget handle that and don't bother with any other handling.

Otherwise if we've started the move process (from mousePressEvent()) then move ourselves into that position, reordering the track list with moveTrackViewUp() and moveTrackViewDown() to suit. We make a note of this in the undo journal in case the user wants to undo this move.

Likewise if we've started a resize process, handle this too, making sure that we never go below the minimum track height.

Parameters

me	The MouseEvent to handle.

mousePressEvent()

void lmms::gui::TrackView::mousePressEvent ( QMouseEvent * me )

overrideprotected

Handle a mouse press event on this track View.

• If this track container supports rubber band selection, let the widget handle that and don't bother with any other handling.
• If the left mouse button is pressed, we handle two things. If SHIFT is pressed, then we resize vertically. Otherwise we start the process of moving this track to a new position.
• Otherwise we let the widget handle the mouse event as normal.

Parameters

me	The MouseEvent to handle.

mouseReleaseEvent()

void lmms::gui::TrackView::mouseReleaseEvent ( QMouseEvent * me )

overrideprotected

Handle a mouse release event on this track View.

Parameters

me	The MouseEvent to handle.

muteChanged
