Variable documentation
bool _
Whether a drag update operation started.
drag_update will be skipped unless this is true or gtk_drag_check_threshold() returns true.
Position _
Fade in/out position at start.
Used when moving fade in/out points.
ArrangerObject* _
The object that was clicked in this drag cycle, if any.
This is the ArrangerObject that was clicked, even though there could be more selected.
This is also used when changing values via the event viewer.
FIXME this sometimes stores project objects (that should not be free'd) and sometimes clones (eg, arranger_object_edit_begin/finish()). Only allow one type.
ArrangerSelections* _
A clone of the ArrangerSelections on drag begin.
When autofilling velocities, this is used to store the affected objects before editing.
This must contain clones only.
float _
Float value at start.
Used when changing the audio region gain.
bool _
Whether the current selections can link (ie, only regions are selected).
To be set on drag begin.
guint _
Drag start button (primary, secondary, etc.).
Can be tested against GDK_BUTTON_SECONDARY and GDK_BUTTON_PRIMARY.
bool _
Whether this is the first time the widget is drawn.
This is used for loading back the scroll positions saved in the project.
PangoLayout* _
Layout for drawing velocity text.
TODO move to Velocity if parallel processing is needed - no need now.
PangoLayout* _
Layout for drawing automation point text.
TODO move to AutomationPoint if parallel processing is needed - no need now.
int _
Cached playhead x to draw.
This is used to avoid queuing drawing at x and then drawing after it (if playhead moved). The playhead will be drawn at the location it was when the draw was queued.
