/** @class wxPGVariantData
	@ingroup classes
    @brief wxVariantData with additional functionality.

    It is usually enough to use supplied to macros to automatically generate
    variant data class. Like so:

    @code

    // In header
    WX_PG_DECLARE_VARIANT_DATA(wxPGVariantDataMyClass,  // Name of the class
                               MyClass,  // Name of the data type
                               wxEMPTY_PARAMETER_VALUE)  // Declaration

    // In source
    WX_PG_IMPLEMENT_VARIANT_DATA(wxPGVariantDataMyClass, MyClass)

    @endcode

    If your class has operator==() implementation, then it is recommended that
    you use WX_PG_IMPLEMENT_VARIANT_DATA_WITH_EQ macro instead, since the
    plain WX_PG_IMPLEMENT_VARIANT_DATA macro only implements a simple, shallow
    equality testing.

    If your class is derived from wxObject, it is recommended that you use
    wxObject-versions of the macros (WX_PG_DECLARE_WXOBJECT_VARIANT_DATA and
    WX_PG_IMPLEMENT_WXOBJECT_VARIANT_DATA).

            - Due to technical reasons, rect's height will be default even if custom height
              was reported during measure call.

/** @class wxPropertyGrid
	@ingroup classes
    @brief
    wxPropertyGrid is a specialized two-column grid for editing properties
    such as strings, numbers, flagsets, fonts, and colours. wxPropertySheet
    used to do the very same thing, but it hasn't been updated for a while
    and it is currently deprecated.

    Please note that most member functions are inherited and as such not documented on
    this page. This means you will probably also want to read wxPropertyGridInterface
    class reference.

    <h4>Derived from</h4>

    wxPropertyGridInterface\n
    wxScrolledWindow\n
    wxPanel\n
    wxWindow\n
    wxEvtHandler\n
    wxObject\n

    <h4>Include files</h4>

    <wx/propertygrid/propertygrid.h>

    <h4>Window styles</h4>

    @link wndflags Additional Window Styles@endlink

    <h4>Event handling</h4>

    To process input from a propertygrid control, use these event handler macros to
    direct input to member functions that take a wxPropertyGridEvent argument.

    <table>
    <tr><td>EVT_PG_SELECTED (id, func)</td><td>Property is selected.</td></tr>
    <tr><td>EVT_PG_CHANGED (id, func)</td><td>Property value is modified.</td></tr>
    <tr><td>EVT_PG_CHANGING (id, func)</td><td>Property value is about to be changed. Use wxPropertyGridEvent::GetValue() to take a peek at the pending value, and wxPropertyGridEvent::Veto() to prevent change from taking place, if necessary.</td></tr>
    <tr><td>EVT_PG_HIGHLIGHTED (id, func)</td><td>Mouse moves over property. Event's property is NULL if hovered on area that is not a property.</td></tr>
    <tr><td>EVT_PG_RIGHT_CLICK (id, func)</td><td>Mouse right-clicked on a property.</td></tr>
    <tr><td>EVT_PG_DOUBLE_CLICK (id, func)</td><td>Mouse double-clicked on a property.</td></tr>
    <tr><td>EVT_PG_ITEM_COLLAPSED (id, func)</td><td>User collapses a property or category.</td></tr>
    <tr><td>EVT_PG_ITEM_EXPANDED (id, func)</td><td>User expands a property or category.</td></tr>
    <tr><td>EVT_PG_LABEL_EDIT_BEGIN (id, func)</td><td>User is about to begin editing a property label. You can veto this event to prevent the action.</td></tr>
    <tr><td>EVT_PG_LABEL_EDIT_ENDING (id, func)</td><td>User is about to end editing of a property label. You can veto this event to prevent the action.</td></tr>

    <tr><td>EVT_BUTTON (id, func)</td><td>Button in a property editor was clicked. Only occurs if the property doesn't handle button clicks itself.</td></tr>
    <tr><td>EVT_TEXT (id, func)</td><td>wxTextCtrl based editor was updated (but property value was not yet modified)</td></tr>
    </table>

    @sa @link wxPropertyGridEvent wxPropertyGridEvent@endlink

    @remarks

    - Following functions do not automatically update the screen: Append. You
      probably need to explicitly call Refresh() <b>if</b> you called one of these
      functions outside parent window constructor.

    - Use Freeze() and Thaw() respectively to disable and enable drawing. This
      will also delay sorting etc. miscellaneous calculations to the last possible
      moment.

    For code examples, see the main page.
