Detailed Description

View is the base class of widgets that display one or more overlaid views of data against a horizontal time scale.

A View may have any number of attached Layers, each of which is expected to have one data Model (although multiple views may share the same model).

A View may be panned in time and zoomed, although the mechanisms for doing so (as well as any other operations and properties available) depend on the subclass.

View::~View ( ) [virtual]

Deleting a View does not delete any of its layers.

They should be managed elsewhere (e.g. by the Document).

void View::setStartFrame ( int  f)

Set the widget pan based on the given first visible frame.

The frame value may be negative.

Definition at line 314 of file View.cpp.

References m_zoomLevel, and setCentreFrame().

Referenced by Pane::zoomToRegion().

int View::getCentreFrame ( ) const [inline]

Return the centre frame of the visible widget.

This is an exact value that does not depend on the zoom block size. Other frame values (start, end) are calculated from this based on the zoom and other factors.

float View::getYForFrequency ( float  frequency,
float  minFreq,
float  maxFreq,
bool  logarithmic 
) const

Return the pixel y-coordinate corresponding to a given frequency, if the frequency range is as specified.

This does not imply any policy about layer frequency ranges, but it might be useful for layers to match theirs up if desired.

Not thread-safe in logarithmic mode. Call only from GUI thread.

Definition at line 377 of file View.cpp.

Referenced by SpectrogramLayer::getYForFrequency(), SpectrogramLayer::paintDrawBufferPeakFrequencies(), and PianoScale::paintPianoVertical().

float View::getFrequencyForY ( int  y,
float  minFreq,
float  maxFreq,

Return the closest frequency to the given pixel y-coordinate, if the frequency range is as specified.

Not thread-safe in logarithmic mode. Call only from GUI thread.

Definition at line 411 of file View.cpp.

Referenced by SpectrogramLayer::getFrequencyForY(), SpectrogramLayer::getSmoothedYBinRange(), and SpectrogramLayer::getYBinRange().

void View::setZoomLevel ( int  z) [virtual]

Set the zoom level, i.e.

the number of frames per pixel. The centre frame will be unchanged; the start and end frames will change.

Definition at line 452 of file View.cpp.

References m_followZoom, m_zoomLevel, and zoomLevelChanged().

Referenced by Pane::horizontalThumbwheelMoved(), setViewManager(), viewZoomLevelChanged(), Pane::wheelVertical(), zoom(), and Pane::zoomToRegion().

void View::zoom ( bool  in) [virtual]

Zoom in or out.

Definition at line 1475 of file View.cpp.

References getZoomConstraintBlockSize(), m_zoomLevel, and setZoomLevel().

void View::scroll ( bool  right,
bool  lots,
bool  doEmit = true 
) [virtual]

Scroll left or right by a smallish or largish amount.

Definition at line 1493 of file View.cpp.

References getEndFrame(), getModelsEndFrame(), getStartFrame(), m_centreFrame, and setCentreFrame().

void View::removeLayer ( Layer v) [virtual]

Remove a layer from the view.

Does not delete the layer. (Normally this should be handled through some command abstraction instead of using this function directly.)

Definition at line 594 of file View.cpp.

References layerNameChanged(), layerParameterRangesChanged(), layerParametersChanged(), m_cache, m_deleting, m_fixedOrderLayers, m_layerStack, m_progressBars, modelAlignmentCompletionChanged(), modelChanged(), modelChangedWithin(), modelCompletionChanged(), modelReplaced(), and propertyContainerRemoved().

virtual Layer* View::getFixedOrderLayer ( int  n) [inline, virtual]

Return the nth layer, counted in the order they were added.

Unlike the stacking order used in getLayer(), which changes each time a layer is selected, this ordering remains fixed. The returned layer may be visible or it may be dormant, i.e. invisible.

Definition at line 186 of file View.h.

References m_fixedOrderLayers.

Return the layer currently active for tool interaction.

This is the topmost non-dormant (i.e. visible) layer in the view. If there are no visible layers in the view, return 0.

const Layer * View::getInteractionLayer ( ) const [virtual]

Definition at line 670 of file View.cpp.

References getInteractionLayer().

Layer * View::getSelectedLayer ( ) [virtual]

Return the layer most recently selected by the user.

This is the layer that any non-tool-driven commands should operate on, in the case where this view is the "current" one.

If the user has selected the view itself more recently than any of the layers on it, this function will return 0, and any non-tool-driven layer commands should be deactivated while this view is current. It will also return 0 if there are no layers in the view.

Note that, unlike getInteractionLayer(), this could return an invisible (dormant) layer.

Definition at line 686 of file View.cpp.

References getSelectedLayer().

virtual Layer* View::getTopLayer ( ) [inline, virtual]

Return the "top" layer in the view, whether visible or dormant.

This is the same as getLayer(getLayerCount()-1) if there is at least one layer, and 0 otherwise.

For most purposes involving interaction or commands, you probably want either getInteractionLayer() or getSelectedLayer() instead.
