Detailed Description

Selection Manager stores a set of selected document objects.

Member Function Documentation

GetRuntimeOverrideSelection()

const ezDeque<const ezDocumentObject*>& ezSelectionManager::GetRuntimeOverrideSelection ( ) const

inline

Returns the current runtime override selection.

Valid, if the selection is non-empty. See SetRuntimeOverrideSelection() for details.

GetTopLevelSelection()

void ezSelectionManager::GetTopLevelSelection

(

ezDynamicArray< ezSelectionEntry > &

out_entries

)

const

Returns the subset of selected items which have no parent selected.

I.e. if an object is selected and one of its ancestors is selected, it is culled from the list. Items are returned in the order of appearance in an expanded scene tree. Their order in the selection is returned through ezSelectionEntry.

SetRuntimeOverrideSelection()

void ezSelectionManager::SetRuntimeOverrideSelection

(

const ezDeque< const ezDocumentObject * > &

selection

)

Sets a separate selection (temporarily), which is sent to the engine but not propagated to the editor.

This is used for cases where temporarily the engine should use a different selection than the editor. Currently this is used during drag-and-drop, to already show the dragged object as selected and especially to exclude it from picking, but not yet show the new object as selected in the property grids, such that users can interact with the previously selected object.

To clear a runtime override selection, simply set an empty selection.
