- Simple string property. wxPG_STRING_PASSWORD attribute may be used
- to echo value as asterisks and use wxTE_PASSWORD for wxTextCtrl.
+typedef void* wxPGChoicesId;
- @remarks
- * wxStringProperty has a special trait: if it has value of "<composed>",

+ wxPGChoiceEntry& Insert( int index, const wxPGChoiceEntry& item );
- @subsection wxUIntProperty
+ // Delete all entries
+ void Clear();
- Like wxIntProperty, but displays value as unsigned int. To set
- the prefix used globally, manipulate wxPG_UINT_PREFIX string attribute.
- To set the globally used base, manipulate wxPG_UINT_BASE int
- attribute. Regardless of current prefix, understands (hex) values starting
- with both "0x" and "$".

- only the filename, not the entire path.
