Detailed Description

Enum property.

An enum property works like a string property all the way through the system property system, except when you get a changed() signal you can call getOptionInt() to get the integer value of the current option. The integer returned will be that passed to addOption() for with the string that is currently selected.

void rviz::EnumProperty::clearOptions ( )

virtual

Clear the list of options.

Does not change the current value of the property.

Definition at line 47 of file enum_property.cpp.

QWidget * rviz::EnumProperty::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 from rviz::Property.

Definition at line 70 of file enum_property.cpp.

int rviz::EnumProperty::getOptionInt ( )

virtual

Return the int value of the currently-chosen option, or 0 if the current option string does not have an int value.

Definition at line 59 of file enum_property.cpp.

void rviz::EnumProperty::requestOptions ( EnumProperty * property_in_need_of_options )

signal

requestOptions() is emitted each time createEditor() is called.

A connection to this signal should never be made with a queued connection, because then the "emit" would return before the changes to the options in the EnumProperty were made.

A connected slot should make calls to clearOptions() and/or addOption() as needed. The option list in the EnumProperty will not be cleared before the signal is emitted.

void rviz::EnumProperty::setString ( const QString & str )

virtualslot

Set the value of this property to the given string. Does not force the value to be one of the list of options.

Definition at line 85 of file enum_property.cpp.

void rviz::EnumProperty::setStringStd ( const std::string & str )

inlineslot

Set the value of this property to the given std::string. Does not force the value to be one of the list of options.

Definition at line 79 of file enum_property.h.

void rviz::EnumProperty::sortOptions ( )

inlineslot

Sort the option strings. Does not change string/int associations.
