Detailed Description

A Display object which stores other Displays as children.

A DisplayGroup can have non-Display child properties as well as Display children, but they are kept separate. Non-display properties come first, and Display children come after. The Property superclass stores the non-Display properties and this class stores the Display objects in a separate list. The separation is enforced in addChild().

Member Function Documentation

void rviz::DisplayGroup::addChild ( Property child,
int  index = -1 
)
virtual

Add a child Property or Display.

Parameters
childThe child to add.
index[optional] The index at which to add the child. If less than 0 or greater than the number of child properties, the child will be added at the end.

This notifies the model about the addition.

This is overridden from Property to keep non-Display child Properties in Property's list of children and Display children in DisplayGroup's list of child Displays.

Reimplemented from rviz::Property.

Definition at line 280 of file display_group.cpp.

void rviz::DisplayGroup::addDisplay ( Display child)
virtual

Add a child Display to the end of the list of Displays.

This also tells the model that we are adding a child, so it can update widgets.

Note
This does not remove child from its parent. That must be done first to avoid problems.

Definition at line 266 of file display_group.cpp.

void rviz::DisplayGroup::addDisplayWithoutSignallingModel ( Display child)

Add a child Display to the end of the list of Displays, but without telling the model.

Property * rviz::DisplayGroup::takeChildAt ( int  index)
virtual

Take a child out of the child list, but don't destroy it.

Returns
Returns the child property at the given index, or NULL if the index is out of bounds.

This notifies the model about the removal.

This is overridden from Property to include Display children.

Reimplemented from rviz::Property.

Display * rviz::DisplayGroup::takeDisplay ( Display child)
virtual

Remove a child Display from the the list of Displays, but don't destroy it.

Returns
Returns child if it is found, or NULL if child is not found.

This also tells the model that we are removing a child, so it can update widgets.

float  ros_dt 
)
