... Assuming that large unsigned magnitudes with high order bit set are not the problem, but signed negatives of small magnitude may be: 1) Always cast the unsigned to signed in comparisons, not the other way. Also: 2) Cast unsigned TERM to signed by itself, before subtracting. Don't cast the result. 3) Rewrite some comparisons by moving subtracted term to other side.

\brief
|
|
Implements TrackPanel and TrackInfo.
|
|
|
|
TrackPanel.cpp is currently some of the worst code in Audacity.
|
|
It's not really unreadable, there's just way too much stuff in this
|
|
one file. Rather than apply a quick fix, the long-term plan
|
|
is to create a GUITrack class that knows how to draw itself
|
|
and handle events. Then this class just helps coordinate
|
|
between tracks.
|
|
|
|
Plans under discussion are described in \ref TrackPanelRefactor
|
|
|
|
*//********************************************************************/

|
// Documentation: Rather than have a lengthy \todo section, having
|
|
// a \todo a \file and a \page in EXACTLY that order gets Doxygen to
|
|
// put the following lengthy description of refactoring on a NEW page
|
|
// and link to it from the docs.

\class TrackPanel
|
|
\brief
|
|
The TrackPanel class coordinates updates and operations on the
|
|
main part of the screen which contains multiple tracks.
|
|
|
|
It uses many other classes, but in particular it uses the
|
|
TrackInfo class to draw the controls area on the left of a track,
|
|
and the TrackArtist class to draw the actual waveforms.
|
|
|
|
Note that in some of the older code here, e.g., GetLabelWidth(),
|
|
"Label" means the TrackInfo plus the vertical ruler.
|
|
Confusing relative to LabelTrack labels.
|
|
|
|
The TrackPanel manages multiple tracks and their TrackInfos.
|
|
|
|
Note that with stereo tracks there will be one TrackInfo
|
|
being used by two wavetracks.
|
|
|
|
*//*****************************************************************//**
|
|
|
|
\class TrackInfo
|
|
\brief
|
|
The TrackInfo is shown to the side of a track
|
|
It has the menus, pan and gain controls displayed in it.
|
|
So "Info" is somewhat a misnomer. Should possibly be "TrackControls".
|
|
|
|
TrackPanel and not TrackInfo takes care of the functionality for
|
|
each of the buttons in that panel.
|
|
|
|
In its current implementation TrackInfo is not derived from a
|
|
wxWindow. Following the original coding style, it has
|
|
been coded as a 'flyweight' class, which is passed
|
|
state as needed, except for the array of gains and pans.
|
|
|
|
If we'd instead coded it as a wxWindow, we would have an instance
|
|
of this class for each instance displayed.

|
|
\brief Planned refactoring of TrackPanel.cpp
|
|
|
|
- Move menus from current TrackPanel into TrackInfo.
|
|
- Convert TrackInfo from 'flyweight' to heavyweight.
|
|
- Split GuiStereoTrack and GuiWaveTrack out from TrackPanel.
|
|
|
|
JKC: Incremental refactoring started April/2003
|
|
|
|
Possibly aiming for Gui classes something like this - it's under
|
|
discussion:
|

|
|
</pre>
|
|
|
|
With the whole lot sitting in a TrackPanel which forwards
|
|
events to the sub objects.
|
|
|
|
The GuiStereoTrack class will do the special logic for
|
|
Stereo channel grouping.
|
|
|
|
The precise names of the classes are subject to revision.
|
|
Have deliberately not created NEW files for the NEW classes
|
|
such as AdornedRulerPanel and TrackInfo - yet.

This is a diagram of TrackPanel's division of one (non-stereo) track rectangle.
|
|
Total height equals Track::GetHeight()'s value. Total width is the wxWindow's width.
|
|
Each charater that is not . represents one pixel.
|
|
|
|
Inset space of this track, and top inset of the next track, are used to draw the focus highlight.
|
|
|
|
Top inset of the right channel of a stereo track, and bottom shadow line of the
|
|
left channel, are used for the channel separator.
|
|
|
|
"Margin" is a term used for inset plus border (top and left) or inset plus
|
|
shadow plus border (right and bottom).
|
|
|
|
TrackInfo::GetTrackInfoWidth() == GetVRulerOffset()
|
|
counts columns from the left edge up to and including controls, and is a constant.
|
|
|
|
GetVRulerWidth() is variable -- all tracks have the same ruler width at any time,
|
|
but that width may be adjusted when tracks change their vertical scales.
|
|
|
|
GetLabelWidth() counts columns up to and including the VRuler.
|
|
GetLeftOffset() is yet one more -- it counts the "one pixel" column.
|
|
|
|
FindCell() for label returns a rectangle that OMITS left, top, and bottom
|
|
margins
|
|
|
|
FindCell() for vruler returns a rectangle right of the label,
|
|
up to and including the One Pixel column, and OMITS top and bottom margins
|
|
|
|
FindCell() for track returns a rectangle with x == GetLeftOffset(), and OMITS
|
|
right top, and bottom margins
