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.
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.
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.
int _
Cache for chord object height, used during child size allocation.
The note currently hovering over
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 automation point text.
TODO move to AutomationPoint if parallel processing is needed - no need now.
