Title: How to write a property editor
Question: Which are the basic steps for writing property editors ?
Answer:
Writing a property editor requires five steps:
1. Deriving a property-editor object
2. Editing the property as text
3. Editing the property as a whole
4. Specifying editor attributes
5. Registering the property editor
Delphi supplies a rich hierarchy of property-editor objects to choose from as
your starting point.
Here's the basic hierarchy;
TPropertyEditor
TOrdinalProperty
TIntegerProperty
TColorProperty
TModalResultProperty
TTabOrderProperty
TCharProperty
TEnumProperty
TSetProperty
TShortCutProperty
TFloatProperty
TStringProperty
TComponentNameProperty
TFontNameProperty
TCaptionProperty
TSetElementProperty
TClassProperty
TFontProperty
TMethodProperty
TComponentProperty

Note that a specific property in Delphi does not know anything about which property editor is used to edit it. In fact, it is really the object inspector that chooses which property editor to use. If you do not like the property editor for a specific property you can use the Tools API to completely replace
it with something else.
