Detailed Description

Represents a type of object that can be selected.

Each Selectable must be able to provide a SelectableClass for itself, so that when there are a bunch of similar objects selected, the class object knows how to deal with them as a group.

getDescriptionOfSelectedGroup()

virtual juce::String tracktion::engine::SelectableClass::getDescriptionOfSelectedGroup ( const SelectableList &  )

virtual

Must return a description of this particular group of objects.

This will be shown on the properties panel.

canBeSelected()

virtual bool tracktion::engine::SelectableClass::canBeSelected ( const Selectable &  object )

virtual

If it's possible for an object to be selected.

Things like currently recording clips should not be selectable

canClassesBeSelectedAtTheSameTime()

virtual bool tracktion::engine::SelectableClass::canClassesBeSelectedAtTheSameTime ( SelectableClass *  otherClass )

virtual

if it's possible for an object of this class to be selected at the same time as an object of the class passed in, this should return true.

Default is only to be true if the other object is actually this one.

canObjectsBeSelectedAtTheSameTime()

virtual bool tracktion::engine::SelectableClass::canObjectsBeSelectedAtTheSameTime ( Selectable &  object1, Selectable &  object2  )

virtual

This is only called if canClassesBeSelectedAtTheSameTime() has already returned true for the other object.

Returns true by default.

addClipboardEntriesFor()

virtual void tracktion::engine::SelectableClass::addClipboardEntriesFor ( AddClipboardEntryParams &  )

virtual

A class should use this to create XML clipboard entries for the given set of items.

deleteSelected()

virtual void tracktion::engine::SelectableClass::deleteSelected ( const DeleteSelectedParams &  params )

virtual

Deletes this set of objects.

The partOfCutOperation flag is set if it's being called from SelectableManager::cutSelected()

pasteClipboard()

virtual bool tracktion::engine::SelectableClass::pasteClipboard ( const SelectableList &  currentlySelectedItems, int  editViewID  )

virtual

This gives the selected items a first chance to paste the clipboard contents when the user presses ctrl-v.

If it doesn't want to handle this, it should return false, and the edit object will be offered the clipboard

canCutSelected()

virtual bool tracktion::engine::SelectableClass::canCutSelected ( const SelectableList &  selectedObjects )

virtual

selectOtherObjects()

virtual void tracktion::engine::SelectableClass::selectOtherObjects ( const SelectOtherObjectsParams &  )

virtual

Must try to find and select objects that are related to these ones in the specified way.

keepSelectedObjectOnScreen()

virtual void tracktion::engine::SelectableClass::keepSelectedObjectOnScreen ( const SelectableList &  currentlySelectedObjects )

virtual

if implemented, this should do whatever is appropriate to make these objects visible - e.g.

scrolling to them, etc.

areAllObjectsOfUniformType()

static bool tracktion::engine::SelectableClass::areAllObjectsOfUniformType ( const SelectableList &  selectedObjects )
