Detailed Description

Storage for "selected" objects.

Object selection is done by storing the "gl-ids" of selectable objects (GUIGlObjects) within internal containers of this class. Each id is stored twice - in a global container and within one of the type-aware containers.

This class allows adding and removing objects (their ids) from the lists of selected objects, saving the lists into a file, and obtaining the lists of selected objects (both all and type-aware).

Most of the adding/removing methods do not require a GUIGlObjectType as parameter, but an integer. This is done to perform the action on objects with a yet unknown type - in this case, the type is obtained internally.

Besides this, the class forces an active view of selected items to refresh its contents if an item is added/removed. For this, an FXWindow has to make itself visible to GUISelectedStorage.

Parameters

[in] updateTarget the callback for selection changes

Definition at line 283 of file GUISelectedStorage.cpp.

Here is the caller graph for this function:

◆ deselect()

void GUISelectedStorage::deselect ( GUIGlID id )

Deselects the object with the given id.

The id of the object is removed from the sub-container that is responsible for objects of the determined type using SingleTypeSelections::deselect and from the global list of chosen items if it is there.

const std::unordered_set< GUIGlID > & GUISelectedStorage::getSelected ( GUIGlObjectType type )

Returns the set of ids of all selected objects' of a certain type.

Parameters

[in] type The type of the object

Returns: A set containing the ids of all selected objects of the given type

◆ isSelected() [2/2]

bool GUISelectedStorage::isSelected	(	GUIGlObjectType	type,
		GUIGlID	id
	)

Returns the information whether the object with the given type and id is selected.

If the type is ==-1, it is determined, first. If it could not be obtained, or if the type is not covered by any selection container, a ProcessError is thrown.

Otherwise, the container holding objects of the determined type is asked whether the given id is stored using SingleTypeSelections::isSelected().

Parameters

[in]	type	The type of the object (GUIGlObjectType or -1)
[in]	id	The id of the object

Returns: Whether the object is selected

Exceptions

ProcessError If the object is not known or the type is not covered by a sub-container
