Detailed Description

A single element of a property tree, with a name, value, description, and possibly children.

A Property in a property tree is a piece of data editable or at least displayable in a PropertyTreeWidget. A Property object owns the data item in question. When client code needs to be informed about changes, it can connect to the Property's aboutToChange() and changed() signals. A slot receiving the changed() signal should then ask the Property itself for the new data. Example:

RangeDisplay::RangeDisplay()
{
  color_property_ = new ColorProperty( "Color", Qt::white,
                                       "Color to draw the range.",
                                       this, SLOT( updateColorAndAlpha() ));
  alpha_property_ = new FloatProperty( "Alpha", 0.5,
                                       "Amount of transparency to apply to the range.",
                                       this, SLOT( updateColorAndAlpha() ));
}
void RangeDisplay::updateColorAndAlpha()
{
  Ogre::ColourValue oc = color_property_->getOgreColor();
  float alpha = alpha_property_->getFloat();
  for( size_t i = 0; i < cones_.size(); i++ )
  {
    cones_[i]->setColor( oc.r, oc.g, oc.b, alpha );
  }
  context_->queueRender();
}

Many subclasses of Property exist with specializations for storing specific types of data. Most of these ultimately use Property::setValue() to store the data in a QVariant.

It is important that knowledge of subclasses not be required to get and set data, so that external code can access and change properties without needing to #include and link against the code in question. For instance:

prop->subProp( "Offset" )->subProp( "X" )->setValue( 3.14 );

Sets the X component of the VectorProperty called "Offset" which is a child of prop. This works without this code needing to know about the existence of VectorProperty.

To show a Property tree in a PropertyTreeWidget, wrap the root Property in a PropertyTreeModel and call PropertyTreeWidget::setModel() with it.

Constructor & Destructor Documentation

◆ Property()

rviz::Property::Property	(	const QString &	name = `QString()`,
		const QVariant	default_value = `QVariant()`,
		const QString &	description = `QString()`,
		Property *	parent = `nullptr`,
		const char *	changed_slot = `nullptr`,
		QObject *	receiver = `nullptr`
	)

Constructor.

Parameters

name	The name of this property. Appears in the left column of a PropertyTreeWidget.
default_value	The initial value to store in the property. Appears in the right column of a PropertyTreeWidget.
description	Text describing the property. Is shown in the "help" area of a PropertyTreeWithHelp widget.
parent	The parent Property, or NULL if there is no parent at this time.
changed_slot	This should be a Qt slot specification, generated by Qt's `SLOT()` macro. It should be a slot on the receiver object, or if receiver is not specified, it should be a slot on the parent.
receiver	If receiver is non-NULL, the changed() signal is connected to the changed_slot on the receiver object.

All parameters to the constructor are optional and can all be set after construction as well.

If a parent is given, this constructor calls parent->addChild(this) to add itself to the parent's list of children.

If changed_slot is given and either parent or receiver is also, then the changed() signal is connected via QObject::connect() to the slot described by changed_slot on the parent or the receiver. If both parent and receiver are specified, receiver is the one which gets connected. If receiver is not specified, parent is used instead.

Definition at line 58 of file property.cpp.

◆ ~Property()

rviz::Property::~Property ( )

override

Destructor. Removes this property from its parent's list of children.

Definition at line 88 of file property.cpp.

Member Function Documentation

◆ aboutToChange

void rviz::Property::aboutToChange ( )

signal

Emitted by setValue() just before the value has changed.

◆ addChild()

void rviz::Property::addChild	(	Property *	child,
		int	index = `-1`
	)

virtual

Add a child property.

Parameters

child	The child property 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.

Reimplemented in rviz::ViewControllerContainer, and rviz::DisplayGroup.

Definition at line 355 of file property.cpp.

◆ changed

void rviz::Property::changed ( )

signal

Emitted by setValue() just after the value has changed.

◆ childAt()

Property * rviz::Property::childAt ( int index ) const

Return the child Property with the given index, or NULL if the index is out of bounds or if the child at that index is not a Property.

This just checks the index against 0 and numChildren() and then calls childAtUnchecked(), so it does not need to be overridden in a subclass.

Definition at line 202 of file property.cpp.

◆ childAtUnchecked()

Property * rviz::Property::childAtUnchecked ( int index ) const

virtual

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

You can override this in a subclass to implement different child storage.

Reimplemented in rviz::DisplayGroup.

Definition at line 213 of file property.cpp.

◆ childListChanged

void rviz::Property::childListChanged ( Property * this_property )

signal

Emitted after insertions and deletions of child Properties.

◆ collapse()

void rviz::Property::collapse ( )

virtual

Collapse (hide the children of) this Property.

Note: Properties start out collapsed by default.

See also: expand()

Definition at line 572 of file property.cpp.

◆ contains()

bool rviz::Property::contains ( Property * possible_child ) const

Return true if the list of children includes possible_child, false if not.

Definition at line 218 of file property.cpp.

◆ createEditor()

QWidget * rviz::Property::createEditor	(	QWidget *	parent,
		const QStyleOptionViewItem &	option
	)

virtual

Create an editor widget to edit the value of this property.

Parameters

parent	The QWidget to set as the parent of the returned QWidget.
option	A QStyleOptionViewItem with parameters of the editor widget, like the rectangle, alignments, etc.

Returns: the newly-created editor widget. The default implementation creates a QSpinBox for integer values, a FloatEdit for float or double values, or a QLineEdit for anything else.

If this function returns NULL, a QStyledItemDelegate will make an editor widget.

The widget returned by createEditor() must have one Q_PROPERTY with USER set to true. The PropertyTreeDelegate finds it, sets it with the results of PropertyTreeModel::data() after creation, and after editing is finished it reads it and calls PropertyTreeModel::setData() with the contents.

Reimplemented in rviz::RegexFilterProperty, rviz::IntProperty, rviz::EnumProperty, rviz::EditableEnumProperty, and rviz::ColorProperty.

Definition at line 525 of file property.cpp.

◆ expand()

void rviz::Property::expand ( )

virtual

Expand (show the children of) this Property.

Note: Properties start out collapsed by default.

This function only works if the property is already owned by a PropertyTreeModel connected to a PropertyTreeWidget. If this is called and the model is subsequently attached to a widget, it will not have any effect.

See also: collapse()

Definition at line 564 of file property.cpp.

◆ getDescription()

Parameters

column	0 for left column, 1 for right column.
role	is a Qt::ItemDataRole

When overriding to add new data (like a color for example), check the role for the thing you know about, and if it matches, return your data. If it does not match, call the parent class version of this function and return its result.

Return values from this function or overridden versions of it are where background and foreground colors, check-box checked-state values, text, and fonts all come from.

Reimplemented in rviz::IconizedProperty, rviz::ViewController, rviz::Display, rviz::StatusProperty, and rviz::FailedDisplay.

Definition at line 241 of file property.cpp.

Definition at line 311 of file property.cpp.

◆ load()

void rviz::Property::load ( const Config & config )

virtual

Load the value of this property and/or its children from the given Config reference.

Reimplemented in rviz::ViewController, rviz::Display, rviz::MarkerDisplay, rviz::DisplayGroup, rviz::TFDisplay, rviz::FailedViewController, rviz::VectorProperty, rviz::QuaternionProperty, and rviz::FailedDisplay.

Definition at line 440 of file property.cpp.

◆ loadValue()

void rviz::Property::loadValue ( const Config & config )

protected

Load the value of this property specifically, not including children.

This handles value_ types of string, double/float, bool, and int. If config is invalid, this does nothing.

Definition at line 463 of file property.cpp.

◆ moveChild()

void rviz::Property::moveChild	(	int	from_index,
		int	to_index
	)

virtual

Move the child at from_index to to_index.

Definition at line 433 of file property.cpp.

◆ numChildren()

virtual int rviz::Property::numChildren ( ) const

inlinevirtual

Hook to provide custom painting of the value data (right-hand column) in a subclass.

Parameters

painter	The QPainter to use.
option	A QStyleOptionViewItem with parameters of the paint job, like the rectangle, alignments, etc.

Returns: true if painting has been done, false if not. The default implementation always returns false.

To implement a custom appearance of a Property value, override this function to do the painting and return true.

If this function returns false, a QStyledItemDelegate will do the painting.

Reimplemented in rviz::ColorProperty.

Definition at line 294 of file property.h.

◆ reindexChildren()

void rviz::Property::reindexChildren ( )

private

Set row_number_within_parent_ correctly for every child. Sets child_indexes_valid_ to true when done.

Definition at line 408 of file property.cpp.

◆ removeChildren()

void rviz::Property::removeChildren	(	int	start_index = `0`,
		int	count = `-1`
	)

virtual

Remove and delete some or all child Properties. Does not change the value of this Property.

Parameters

start_index	The index of the first child to delete.
count	The number of children to delete, or -1 to delete from start_index to the end of the list.

Does not use numChildren() or takeChildAt(), operates directly on internal children_ list.

Definition at line 104 of file property.cpp.

◆ rowNumberInParent()

int rviz::Property::rowNumberInParent ( ) const

Return the row number of this property within its parent, or -1 if it has no parent.

This checks child_indexes_valid_ in the parent Property, and if it is false calls reindexChildren(). Then returns row_number_within_parent_ regardless.

Definition at line 419 of file property.cpp.

◆ save()

void rviz::Property::save ( Config config ) const

virtual

Write the value of this property and/or its children into the given Config reference.

void rviz::Property::setDescription ( const QString & description )

virtual

Set the description.

Parameters

description the new description.

Definition at line 169 of file property.cpp.

◆ setHidden()

void rviz::Property::setHidden ( bool hidden )

virtual

Hide or show this property in any PropertyTreeWidget viewing its parent.

The hidden/shown state is not saved or loaded, it is expected to be managed by the owner of the property.

Definition at line 552 of file property.cpp.

◆ setIcon()

virtual void rviz::Property::setIcon ( const QIcon & icon )

inlinevirtual

Set the icon to be displayed next to the property.

Reimplemented in rviz::IconizedProperty.

Definition at line 193 of file property.h.

◆ setModel()

void rviz::Property::setModel ( PropertyTreeModel * model )

Set the model managing this Property and all its child properties, recursively.

Definition at line 393 of file property.cpp.

◆ setName()

void rviz::Property::setName ( const QString & name )

virtual

Set the name.

Parameters

name	the new name.

Internally, the name is stored with QObject::setObjectName().

Reimplemented in rviz::Display, and rviz::StatusList.

Definition at line 155 of file property.cpp.

◆ setParent()

void rviz::Property::setParent ( Property * new_parent )

Set parent property, without telling the parent.

Unlike specifying the parent property to the constructor, setParent() does not have any immediate side effects, like adding itself to be a child of the parent. It should only be used by implementations of addChild() and takeChild() and such.

Definition at line 236 of file property.cpp.

◆ setReadOnly()

virtual void rviz::Property::setReadOnly ( bool read_only )

inlinevirtual

Prevent or allow users to edit this property from a PropertyTreeWidget.

This only applies to user edits. Calling setValue() will still change the value.

This is not inherently recursive. Parents which need this to propagate to their children must override this to implement that.

Reimplemented in rviz::VectorProperty, and rviz::QuaternionProperty.

Definition at line 436 of file property.h.

◆ setShouldBeSaved()

void rviz::Property::setShouldBeSaved ( bool save )

inline

If save is true and getReadOnly() is false, shouldBeSaved will return true; otherwise false. Default is true.

Definition at line 388 of file property.h.

◆ setValue()

bool rviz::Property::setValue ( const QVariant & new_value )

virtual

Set the new value for this property. Returns true if the new value is different from the old value, false if same.

Parameters

new_value The new value to store.

Returns: Returns true if new_value is different from current value, false if they are the same.

If the new value is different from the old value, this emits aboutToChange() before changing the value and emits changed() after.

If the value set is an invalid QVariant (QVariant::isValid() returns false), the value will not be editable in a PropertyTreeWidget.

Reimplemented in rviz::IntProperty, rviz::VectorProperty, rviz::FloatProperty, rviz::QuaternionProperty, rviz::TfFrameProperty, rviz::StatusProperty, and rviz::ColorProperty.

Definition at line 134 of file property.cpp.

◆ shouldBeSaved()

bool rviz::Property::shouldBeSaved ( ) const

inline

Returns true if the property is not read-only AND has data worth saving.

Definition at line 381 of file property.h.

◆ show()

void rviz::Property::show ( )

inline

Show this Property in any PropertyTreeWidgets.

This is a convenience function which calls setHidden( false ).

See also: show(), setHidden(), getHidden()

Definition at line 410 of file property.h.

◆ subProp()

Property * rviz::Property::subProp ( const QString & sub_name )

virtual

Return the first child Property with the given name, or the FailureProperty if no child has the name.

If no child is found with the given name, an instance of a special Property subclass named FailureProperty is returned and an error message is printed to stdout. FailureProperty::subProp() always returns itself, which means you can safely chain a bunch of subProp() calls together and not have a crash even if one of the sub-properties does not actually exist. For instance:

float width = prop->subProp( "Dimenshons" )->subProp( "Width" )->getValue().toFloat();

If the first property prop has a "Dimensions" property but not a "Dimenshons" one, width will end up set to 0 and an error message will be printed, but the program will not crash here.

This is an Order(N) operation in the number of subproperties.

Reimplemented in rviz::FailureProperty.

Definition at line 179 of file property.cpp.

◆ takeChild()

Property * rviz::Property::takeChild ( Property * child )

Remove a given child object and return a pointer to it.

Returns: If child is contained here, it is returned; otherwise NULL.

This performs a linear search through all the children.

This uses only virtual functions, numChildren(), childAtUnchecked(), and takeChildAt(), so it does not need to be virtual itself.

Definition at line 321 of file property.cpp.

◆ takeChildAt()

Property * rviz::Property::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.

Reimplemented in rviz::DisplayGroup.

Definition at line 333 of file property.cpp.

Functions to notify it of changes include PropertyTreeModel::beginInsert(), PropertyTreeModel::endInsert(), PropertyTreeModel::beginRemove(), PropertyTreeModel::endRemove(), and PropertyTreeModel::emitDataChanged(). The Property class already does this for itself, but subclasses must be aware of it if they override functions which modify the structure or contents of the tree.
