13 SetWindowStyleFlag method can be used to modify some of these at run-time.
16 enum wxPG_WINDOW_STYLES
20 This will cause Sort() automatically after an item is added.
21 When inserting a lot of items in this mode, it may make sense to
22 use Freeze() before operations and Thaw() afterwards to increase
25 wxPG_AUTO_SORT
= 0x00000010,
28 Categories are not initially shown (even if added).
29 IMPORTANT NOTE: If you do not plan to use categories, then this
30 style will waste resources.
31 This flag can also be changed using wxPropertyGrid::EnableCategories method.
33 wxPG_HIDE_CATEGORIES
= 0x00000020,
36 This style combines non-categoric mode and automatic sorting.
38 wxPG_ALPHABETIC_MODE
= (wxPG_HIDE_CATEGORIES
|wxPG_AUTO_SORT
),
41 Modified values are shown in bold font. Changing this requires Refresh()
44 wxPG_BOLD_MODIFIED
= 0x00000040,
47 When wxPropertyGrid is resized, splitter moves to the center. This
48 behavior stops once the user manually moves the splitter.
50 wxPG_SPLITTER_AUTO_CENTER
= 0x00000080,
53 Display tool tips for cell text that cannot be shown completely. If
54 wxUSE_TOOLTIPS is 0, then this doesn't have any effect.
56 wxPG_TOOLTIPS
= 0x00000100,
59 Disables margin and hides all expand/collapse buttons that would appear
60 outside the margin (for sub-properties). Toggling this style automatically
61 expands all collapsed items.
63 wxPG_HIDE_MARGIN
= 0x00000200,
66 This style prevents user from moving the splitter.
68 wxPG_STATIC_SPLITTER
= 0x00000400,
71 Combination of other styles that make it impossible for user to modify
74 wxPG_STATIC_LAYOUT
= (wxPG_HIDE_MARGIN
|wxPG_STATIC_SPLITTER
),
77 Disables wxTextCtrl based editors for properties which
78 can be edited in another way. Equals calling
79 wxPropertyGrid::LimitPropertyEditing() for all added properties.
81 wxPG_LIMITED_EDITING
= 0x00000800,
84 wxPropertyGridManager only: Show tool bar for mode and page selection.
86 wxPG_TOOLBAR
= 0x00001000,
89 wxPropertyGridManager only: Show adjustable text box showing description
90 or help text, if available, for currently selected property.
92 wxPG_DESCRIPTION
= 0x00002000
96 enum wxPG_EX_WINDOW_STYLES
100 NOTE: wxPG_EX_xxx are extra window styles and must be set using SetExtraStyle()
103 Speeds up switching to wxPG_HIDE_CATEGORIES mode. Initially, if
104 wxPG_HIDE_CATEGORIES is not defined, the non-categorized data storage is not
105 activated, and switching the mode first time becomes somewhat slower.
106 wxPG_EX_INIT_NOCAT activates the non-categorized data storage right away.
108 NOTE: If you do plan not switching to non-categoric mode, or if
109 you don't plan to use categories at all, then using this style will result
110 in waste of resources.
112 wxPG_EX_INIT_NOCAT
= 0x00001000,
115 Extended window style that sets wxPropertyGridManager tool bar to not
118 wxPG_EX_NO_FLAT_TOOLBAR
= 0x00002000,
121 Shows alphabetic/categoric mode buttons from tool bar.
123 wxPG_EX_MODE_BUTTONS
= 0x00008000,
126 Show property help strings as tool tips instead as text on the status bar.
127 You can set the help strings using SetPropertyHelpString member function.
129 wxPG_EX_HELP_AS_TOOLTIPS
= 0x00010000,
132 Allows relying on native double-buffering.
134 wxPG_EX_NATIVE_DOUBLE_BUFFERING
= 0x00080000,
137 Set this style to let user have ability to set values of properties to
138 unspecified state. Same as setting wxPG_PROP_AUTO_UNSPECIFIED for
141 wxPG_EX_AUTO_UNSPECIFIED_VALUES
= 0x00200000,
144 If this style is used, built-in attributes (such as wxPG_FLOAT_PRECISION and
145 wxPG_STRING_PASSWORD) are not stored into property's attribute storage (thus
146 they are not readable).
148 Note that this option is global, and applies to all wxPG property containers.
150 wxPG_EX_WRITEONLY_BUILTIN_ATTRIBUTES
= 0x00400000,
153 With this style Validators on properties will work same as in wxPropertyGrid
156 wxPG_EX_LEGACY_VALIDATORS
= 0x00800000,
159 Hides page selection buttons from tool bar.

287 wxPropertyGrid is a specialized grid for editing properties - in other
288 words name = value pairs. List of ready-to-use property classes include
289 strings, numbers, flag sets, fonts, colours and many others. It is possible,
290 for example, to categorize properties, set up a complete tree-hierarchy,
291 add more than two columns, and set arbitrary per-property attributes.
293 Please note that most member functions are inherited and as such not
294 documented on this page. This means you will probably also want to read
295 wxPropertyGridInterface class reference.

303 @section propgrid_event_handling Event Handling
305 To process input from a property grid control, use these event handler macros
306 to direct input to member functions that take a wxPropertyGridEvent argument.
308 @beginEventTable{wxPropertyGridEvent}
309 @event{EVT_PG_SELECTED (id, func)}
310 Respond to wxEVT_PG_SELECTED event, generated when property value
311 has been changed by user.
312 @event{EVT_PG_CHANGING(id, func)}
313 Respond to wxEVT_PG_CHANGING event, generated when property value
314 is about to be changed by user. Use wxPropertyGridEvent::GetValue()
315 to take a peek at the pending value, and wxPropertyGridEvent::Veto()
316 to prevent change from taking place, if necessary.
317 @event{EVT_PG_HIGHLIGHTED(id, func)}
318 Respond to wxEVT_PG_HIGHLIGHTED event, which occurs when mouse
319 moves over a property. Event's property is NULL if hovered area does
320 not belong to any property.
321 @event{EVT_PG_RIGHT_CLICK(id, func)}
322 Respond to wxEVT_PG_RIGHT_CLICK event, which occurs when property is
323 clicked on with right mouse button.
324 @event{EVT_PG_DOUBLE_CLICK(id, func)}
325 Respond to wxEVT_PG_DOUBLE_CLICK event, which occurs when property is
326 double-clicked on with left mouse button.
327 @event{EVT_PG_ITEM_COLLAPSED(id, func)}
328 Respond to wxEVT_PG_ITEM_COLLAPSED event, generated when user collapses
329 a property or category.
330 @event{EVT_PG_ITEM_EXPANDED(id, func)}
331 Respond to wxEVT_PG_ITEM_EXPANDED event, generated when user expands
332 a property or category.
