12 @class wxPropertyGridInterface
14 Most of the shared property manipulation interface shared by wxPropertyGrid,
15 wxPropertyGridPage, and wxPropertyGridManager is defined in this class.
18 - In separate wxPropertyGrid component this class was known as
19 wxPropertyContainerMethods.
21 - wxPropertyGridInterface's property operation member functions all accept
22 a special wxPGPropArg id argument, using which you can refer to properties
23 either by their pointer (for performance) or by their name (for conveniency).
28 class WXDLLIMPEXP_PROPGRID wxPropertyGridInterface
33 virtual ~wxPropertyGridInterface() { }
36 Appends property to the list. wxPropertyGrid assumes ownership of the
37 object. Becomes child of most recently added category.
40 - wxPropertyGrid takes the ownership of the property pointer.
41 - If appending a category with name identical to a category already in
42 the wxPropertyGrid, then newly created category is deleted, and most
43 recently added category (under which properties are appended) is set
44 to the one with same name. This allows easier adding of items to same
45 categories in multiple passes.
46 - Does not automatically redraw the control, so you may need to call
47 Refresh() when calling this function after control has been shown for
50 wxPGProperty
* Append( wxPGProperty
* property
);
53 Same as Append(), but appends under given parent property.
56 Name or pointer to parent property.
61 wxPGProperty
* AppendIn( wxPGPropArg id
, wxPGProperty
* newProperty
);
64 In order to add new items into a property with private children (for
65 instance, wxFlagsProperty), you need to call this method. After
66 populating has been finished, you need to call EndAddChildren().
70 void BeginAddChildren( wxPGPropArg id
);
73 Deletes all properties.
75 virtual void Clear() = 0;
78 Deselect current selection, if any.
80 @return Returns @true if success (ie. validator did not intercept).
82 bool ClearSelection();
85 Resets modified status of all properties.
87 void ClearModifiedStatus();
90 Collapses given category or property with children.
92 @return Returns @true if actually collapsed.
94 bool Collapse( wxPGPropArg id
);
97 Collapses all items that can be collapsed.
99 @return Returns @false if failed (may fail if value in active
100 editor cannot be validated).
105 Changes value of a property, as if by user. Use this instead of
106 SetPropertyValue() if you need the value to run through validation
107 process, and also send the property change event.
109 @return Returns @true if value was successfully changed.
111 bool ChangePropertyValue( wxPGPropArg id
, wxVariant newValue
);
116 void DeleteProperty( wxPGPropArg id
);
121 bool DisableProperty( wxPGPropArg id
);
124 Returns true if all property grid data changes have been committed. Usually
125 only returns false if value in active editor has been invalidated by a
128 bool EditorValidate();
131 Enables or disables property.
134 Name or pointer to a property.
137 If @false, property is disabled instead.
139 bool EnableProperty( wxPGPropArg id
, bool enable
= true );
142 Called after population of property with fixed children has finished.
144 @see BeginAddChildren()
146 void EndAddChildren( wxPGPropArg id
);
149 Expands given category or property with children.
151 @return Returns @true if actually expanded.
153 bool Expand( wxPGPropArg id
);
156 Expands all items that can be expanded.
158 bool ExpandAll( bool expand
= true );
161 Returns id of first child of given property.
163 @remarks Does not return private children!

180 from the first property from the top, and wxBOTTOM means that the

402 If index is < 0, property is appended in category.
404 @return Returns newProperty.
408 - wxPropertyGrid takes the ownership of the property pointer.
410 - While Append may be faster way to add items, make note that when
411 both types of data storage (categoric and
412 non-categoric) are active, Insert becomes even more slow. This is
413 especially true if current mode is non-categoric.

473 Initializes additional property editors (SpinCtrl etc.). Causes
474 references to most object files in the library, so calling this may
475 cause significant increase in executable size when linking with static

481 Replaces property with id with newly created one. For example,
482 this code replaces existing property named "Flags" with one that
483 will have different set of items:
