+wxPropertyGrid is a specialized grid for editing properties - in other words
+name = value pairs. List of ready-to-use property classes include strings,
+numbers, flag sets, fonts, colours and many others. It is possible, for
+example, to categorize properties, set up a complete tree-hierarchy, add more
+than two columns, and set arbitrary per-property attributes.
+
+As this version of wxPropertyGrid has some backward-incompatible changes from
+version 1.4, everybody who need to maintain custom property classes should
+carefully read final section in @ref propgrid_compat.

-  Operations on properties should be done either via wxPropertyGrid's
-(or wxPropertyGridManager's) methods, or by acquiring pointer to a property

-automatically update grid graphics.
+  Operations on properties are usually done by directly calling wxPGProperty's
+or wxPropertyGridInterface's member functions. wxPropertyGridInterface is an
+abstract base class for property containers such as wxPropertyGrid,
+wxPropertyGridManager, and wxPropertyGridPage. Note however that wxPGProperty's
+member functions generally do not refresh the grid.

 
 

-  Property container functions operating on properties, such as SetPropertyValue or
-DisableProperty, all accept a special wxPGPropArg, argument which can automatically
-convert name of a property to a pointer. For instance:

+argument, using which you can refer to properties either by their pointer

+@section propgrid_processingvalues Processing Property Values
+
+Properties store their values internally as wxVariant, but is also possible to
+obtain them as wxAny, using implicit conversion. You can get property
+values with wxPGProperty::GetValue() and
+wxPropertyGridInterface::GetPropertyValue().
+
+Below is a code example which handles wxEVT_PG_CHANGED event:
+
+@code
+
+void MyWindowClass::OnPropertyGridChanged(wxPropertyGridEvent& event)
+{
+    wxPGProperty* property = event.GetProperty();
+
+    // Do nothing if event did not have associated property
+    if ( !property )
+        return;
+
+    // GetValue() returns wxVariant, but it is converted transparently to
+    // wxAny
+    wxAny value = property->GetValue();
+
+    // Also, handle the case where property value is unspecified
+    if ( value.IsNull() )
+        return;
+
+    // Handle changes in values, as needed
+    if ( property->GetName() == "MyStringProperty" )
+        OnMyStringPropertyChanged(value.As<wxString>());
+    else if ( property->GetName() == "MyColourProperty" )
+        OnMyColourPropertyChanged(value.As<wxColour>());
+}
+
+@endcode
+
+You can get a string-representation of property's value using
+wxPGProperty::GetValueAsString() or
+wxPropertyGridInterface::GetPropertyValueAsString(). This particular function
+is very safe to use with any kind of property.
+
+@note There is a one case in which you may want to take extra care when
+      dealing with raw wxVariant values. That is, integer-type properties,
+      such as wxIntProperty and wxUIntProperty, store value internally as
+      wx(U)LongLong when number doesn't fit into standard long type. Using
+      << operator to get wx(U)LongLong from wxVariant is customized to work
+      quite safely with various types of variant data. However, you can also
+      bypass this problem by using wxAny in your code instead of wxVariant.
+
+Note that in some cases property value can be Null variant, which means
+that property value is unspecified. This usually occurs only when
+wxPG_EX_AUTO_UNSPECIFIED_VALUES extra window style is defined or when you
+manually set property value to Null (or unspecified).

+@section propgrid_keyhandling Customizing Keyboard Handling
+
+There is probably one preference for keyboard handling for every developer
+out there, and as a conveniency control wxPropertyGrid tries to cater for
+that. By the default arrow keys are used for navigating between properties,
+and TAB key is used to move focus between the property editor and the
+first column. When the focus is in the editor, arrow keys usually no longer
+work for navigation since they are consumed by the editor.
+
+There are mainly two functions which you can use this customize things,
+wxPropertyGrid::AddActionTrigger() and wxPropertyGrid::DedicateKey().
+First one can be used to set a navigation event to occur on a specific key
+press and the second is used to divert a key from property editors, making it
+possible for the grid to use keys normally consumed by the focused editors.
+
+For example, let's say you want to have an ENTER-based editing scheme. That
+is, editor is focused on ENTER press and the next property is selected when
+the user finishes editing and presses ENTER again. Code like this would
+accomplish the task:
+
+@code
+    // Have property editor focus on Enter
+    propgrid->AddActionTrigger( wxPG_ACTION_EDIT, WXK_RETURN );
+    
+    // Have Enter work as action trigger even when editor is focused
+    propgrid->DedicateKey( WXK_RETURN );
+    
+    // Let Enter also navigate to the next property
+    propgrid->AddActionTrigger( wxPG_ACTION_NEXT_PROPERTY, WXK_RETURN );
+
+@endcode
+
+wxPG_ACTION_EDIT is prioritized above wxPG_ACTION_NEXT_PROPERTY so that the
+above code can work without conflicts. For a complete list of available
+actions, see @ref propgrid_keyboard_actions.
+
+Here's another trick. Normally the up and down cursor keys are consumed by
+the focused wxTextCtrl editor and as such can't be used for navigating between
+properties when that editor is focused. However, using DedicateKey() we can
+change this so that instead of the cursor keys moving the caret inside the
+wxTextCtrl, they navigate between adjacent properties. As such:
+
+@code
+    propgrid->DedicateKey(WXK_UP);
+    propgrid->DedicateKey(WXK_DOWN);
+@endcode

-wxPropertyGridManager inherits from wxPropertyGridInterface, and as such
-it has most property manipulation functions. However, only some of them affect

-(eg. Append()) only apply to the currently selected page.

+
+Version of wxPropertyGrid bundled with wxWidgets 2.9+ has various backward-

+
+Note that in general any behaviour-breaking changes should not compile or run

+
+@subsection propgrid_compat_general General Changes
+
+  - Tab-traversal can no longer be used to travel between properties. Now
+    it only causes focus to move from main grid to editor of selected property.
+    Arrow keys are now your primary means of navigating between properties,
+    with keyboard. This change allowed fixing broken tab traversal on wxGTK
+    (which is open issue in wxPropertyGrid 1.4).
+
+  - wxPG_EX_UNFOCUS_ON_ENTER style is removed and is now default behaviour.
+    That is, when enter is pressed, editing is considered done and focus
+    moves back to the property grid from the editor control.
+
+  - A few member functions were removed from wxPropertyGridInterface.
+    Please use wxPGProperty's counterparts from now on.
+
+  - wxPGChoices now has proper Copy-On-Write behaviour.
+
+  - wxPGChoices::SetExclusive() was renamed to AllocExclusive().
+
+  - wxPGProperty::SetPropertyChoicesExclusive() was removed. Instead, use
+    GetChoices().AllocExclusive().

 
 

+  - wxPGProperty::ClearModifiedStatus() is removed. Please use
+    SetModifiedStatus() instead.
+
+  - wxPropertyGridInterface::GetExpandedProperties() is removed. You should
+    now use wxPropertyGridInterface::GetEditableState() instead.
+
+  - wxPG_EX_DISABLE_TLP_TRACKING is now enabled by default. To get the old
+    behaviour (recommended if you don't use a system that reparents the grid
+    on its own), use the wxPG_EX_ENABLE_TLP_TRACKING extra style.
+
+  - Extended window style wxPG_EX_LEGACY_VALIDATORS was removed.
+
+  - Default property validation failure behaviour has been changed to
+    (wxPG_VFB_MARK_CELL | wxPG_VFB_SHOW_MESSAGEBOX), which means that the
+    cell is marked red and wxMessageBox is shown. This is more user-friendly
+    than the old behaviour, which simply beeped and prevented leaving the
+    property editor until a valid value was entered.
+
+  - wxPropertyGridManager now has same Get/SetSelection() semantics as
+    wxPropertyGrid.
+
+  - Various wxPropertyGridManager page-related functions now return pointer
+    to the page object instead of index.
+
+  - wxArrayEditorDialog used by wxArrayStringProperty and some sample
+    properties has been renamed to wxPGArrayEditorDialog. Also, it now uses
+    wxEditableListBox for editing.
+
+  - Instead of calling wxPropertyGrid::SetButtonShortcut(), use
+    wxPropertyGrid::SetActionTrigger(wxPG_ACTION_PRESS_BUTTON).
+
+  - wxPGProperty::GetCell() now returns a reference. AcquireCell() was removed.
+
+  - wxPGMultiButton::FinalizePosition() has been renamed to Finalize(),
+    and it has slightly different argument list.
+
+  - wxPropertyGridEvent::HasProperty() is removed. You can use GetProperty()
+    as immediate replacement when checking if event has a property.
+
+  - "InlineHelp" property has been replaced with "Hint".
+
+  - wxPropertyGrid::CanClose() has been removed. Call
+    wxPropertyGridInterface::EditorValidate() instead.
+
+  - wxPGProperty::SetFlag() has been moved to private API. This was done to
+    underline the fact that it was not the preferred method to change a
+    property's state since it never had any desired side-effects. ChangeFlag()
+    still exists for those who really need to achieve the same effect.
+
+  - wxArrayStringProperty default delimiter is now comma (','), and it can
+    be changed by setting the new "Delimiter" attribute.
+
+@subsection propgrid_compat_propdev Property and Editor Sub-classing Changes
+
+  - Confusing custom property macros have been eliminated.
+
+  - Implement wxPGProperty::ValueToString() instead of GetValueAsString().
+
+  - wxPGProperty::ChildChanged() must now return the modified value of
+    whole property instead of writing it back into 'thisValue' argument.
+
+  - Removed wxPropertyGrid::PrepareValueForDialogEditing(). Use
+    wxPropertyGrid::GetPendingEditedValue() instead.
+
+  - wxPGProperty::GetChoiceInfo() is removed, as all properties now carry
+    wxPGChoices instance (protected wxPGProperty::m_choices).
+
+  - Connect() should no longer be called in implementations of
+    wxPGEditor::CreateControls(). wxPropertyGrid automatically passes all
+    events from editor to wxPGEditor::OnEvent() and wxPGProperty::OnEvent(),
+    as appropriate.
+
+  - wxPython: Previously some of the reimplemented member functions needed a
+    'Py' prefix. This is no longer necessary. For instance, if you previously
+    implemented PyStringToValue() for your custom property, you should now
+    just implement StringToValue().
