Detailed Description

The base class representing a single property.

It can hold a property of any type supported by TQVariant. You can also create you own property types (see Using Custom Properties in Factory doc). As a consequence, do not subclass Property, use CustomProperty instead.
Each property stores old value to allow undo. It has a name (a TQCString), a caption (i18n'ed name shown in Editor) and a description (also i18n'ed).
It also supports setting arbitrary number of options (of type option=value). See Editor for a list of options, and their meaning.

// To create a property
property = Property(name, value, caption, description); // name is a TQCString,
// value is whatever type TQVariant supports
 
// To create a valueFromList property (matching strings with strings)
TQStringList keys, strings;
keys << "one" << "two" << "three"; // possible values of the property
// Strings (possibly i18n-ed) shown in the editor instead of the values
strings << i18n("One") << i18n("Two") << i18n("Three");
property = Property(name, keys, strings, "two", caption);
 
// To create a valueFromList property (matching strings with TQVariant)
TQValueList<TQVariant> keys2;
keys2.append(1);
keys2.append(2);
keys2.append(3);
Property::ListData listData(keys2, strings);
m_set->addProperty(new Property("List2", listData, "otheritem", "List2"), group);

Note that you need to use TQVariant(bool, int) to create a boolean property value. See TQVariant docs for more details.

Sometimes, for longer property captions or these with more words, e.g. "Allow Zero Size", it's usable to provide newline characters, e.g. "Allow Zero\nSize". If caption argument of the constructors contains newline characters, caption() will return this text with substituted these characters with spaces. In such cases, captionForDisplaying() is used to get the original caption text usable (with newline, if any) for displaying within a property editor.
