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:

child	The 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 ) [protected, virtual]

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

Definition at line 256 of file display_group.cpp.

Property * rviz::DisplayGroup::childAtUnchecked ( int index ) const [virtual]

Return the child with the given index, without checking whether the index is within bounds.

Overridden from Property to include Display children.

Reimplemented from rviz::Property.

Definition at line 350 of file display_group.cpp.

Display * rviz::DisplayGroup::createDisplay ( const QString & class_id )

Definition at line 119 of file display_group.cpp.

void rviz::DisplayGroup::displayAdded ( rviz::Display * display ) [signal]

void rviz::DisplayGroup::displayRemoved ( rviz::Display * display ) [signal]

void rviz::DisplayGroup::fixedFrameChanged ( ) [protected, virtual]

Update the fixed frame in all contained displays.

Reimplemented from rviz::Display.

Definition at line 223 of file display_group.cpp.

Display * rviz::DisplayGroup::getDisplayAt ( int index ) const [virtual]

Return the index-th Display in this group, or NULL if the index is invalid.

Definition at line 209 of file display_group.cpp.

DisplayGroup * rviz::DisplayGroup::getGroupAt ( int index ) const [virtual]

Find the index-th child Display in this group. If the child is itself a DisplayGroup, return the pointer to it. If it is not, return NULL.

Definition at line 218 of file display_group.cpp.

Qt::ItemFlags rviz::DisplayGroup::getViewFlags ( int column ) const [virtual]

Return item flags appropriate for the given column (0 or 1) for this DisplayGroup.

Reimplemented from rviz::Display.

Definition at line 53 of file display_group.cpp.

void rviz::DisplayGroup::load ( const Config & config ) [virtual]

Load subproperties and the list of displays in this group from the given Config node, which must be a map.

Reimplemented from rviz::Display.

Definition at line 58 of file display_group.cpp.

int rviz::DisplayGroup::numChildren ( ) const [virtual]

Return the number of child objects (Property and Display).

Overridden from Property to include the number of child Displays.

Reimplemented from rviz::Property.

Definition at line 345 of file display_group.cpp.

int rviz::DisplayGroup::numDisplays ( ) const [virtual]

Return the number of child Displays.

Definition at line 340 of file display_group.cpp.

void rviz::DisplayGroup::onEnableChanged ( ) [virtual, slot]

Reimplemented from rviz::Display.

Definition at line 131 of file display_group.cpp.

void rviz::DisplayGroup::removeAllDisplays ( ) [virtual]

Remove and destroy all child Displays, but preserve any non-Display children.

Definition at line 154 of file display_group.cpp.

void rviz::DisplayGroup::reset ( ) [virtual]

Reset this and all child Displays.

Reimplemented from rviz::Display.

Definition at line 245 of file display_group.cpp.

void rviz::DisplayGroup::save ( Config config ) const [virtual]

Save subproperties and the list of displays in this group to the given Config node.

Reimplemented from rviz::Display.

Definition at line 140 of file display_group.cpp.

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.

Definition at line 315 of file display_group.cpp.

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.

Definition at line 181 of file display_group.cpp.

void rviz::DisplayGroup::update	(	float	wall_dt,
		float	ros_dt
	)		`[virtual]`

Call update() on all child Displays.

Reimplemented from rviz::Display.

Definition at line 232 of file display_group.cpp.
