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
49 - This functions deselects selected property, if any. Validation
50 failure option wxPG_VFB_STAY_IN_PROPERTY is not respected, ie.
51 selection is cleared even if editor had invalid value.
53 wxPGProperty

);
56 Same as Append(), but appends under given parent property.
59 Name or pointer to parent property.
64 wxPGProperty
* AppendIn( wxPGPropArg id
, wxPGProperty
* newProperty
);
67 In order to add new items into a property with private children (for
68 instance, wxFlagsProperty), you need to call this method.
69 After populating has been finished, you need to call EndAddChildren().
73 void BeginAddChildren( wxPGPropArg id
);
76 Deletes all properties.
78 @remarks This functions deselects selected property, if any. Validation
79 failure option wxPG_VFB_STAY_IN_PROPERTY is not respected, ie.
80 selection is cleared even if editor had invalid value.
82 virtual void Clear() = 0;
85 Clears current selection, if any.
88 If set to @false, deselecting the property will always work,
89 even if its editor had invalid value in it.
91 @return Returns @true if successful or if there was no selection. May
92 fail if validation was enabled and active editor had invalid

103 Collapses given category or property with children.

108 failure option wxPG_VFB_STAY_IN_PROPERTY is not respected, ie.

116 @remarks This functions clears selection. Validation failure option
117 wxPG_VFB_STAY_IN_PROPERTY is not respected, ie. selection
118 is cleared even if editor had invalid value.
123 Changes value of a property, as if by user. Use this instead of
124 SetPropertyValue() if you need the value to run through validation
125 process, and also send the property change event.
127 @return Returns @true if value was successfully changed.

146 Returns @true if all property grid data changes have been committed. Usually
147 only returns @false if value in active editor has been invalidated by a

153 Enables or disables property.
156 Name or pointer to a property.
