## Typedef Documentation

typedef int(* wxPGSortCallback)(wxPropertyGrid *propGrid, wxPGProperty *p1, wxPGProperty *p2)

This callback function is used for sorting properties.

Call wxPropertyGrid::SetSortFunction() to set it.

Sort function should return a value greater than 0 if position of p1 is after p2. So, for instance, when comparing property names, you can use following implementation:

                int MyPropertySortFunction(wxPropertyGrid* propGrid,
                                           wxPGProperty* p1,
                                           wxPGProperty* p2)
                {
                    return p1->GetBaseName().compare( p2->GetBaseName() );
                }

## Enumeration Type Documentation

enum wxPG_EX_WINDOW_STYLES

Combines various styles.

Enumerator:

  wxPG_EX_INIT_NOCAT | NOTE: wxPG_EX_xxx are extra window styles and must be set using SetExtraStyle() member function. Speeds up switching to wxPG_HIDE_CATEGORIES mode. Initially, if wxPG_HIDE_CATEGORIES is not defined, the non-categorized data storage is not activated, and switching the mode first time becomes somewhat slower. wxPG_EX_INIT_NOCAT activates the non-categorized data storage right away. NOTE: If you do plan not switching to non-categoric mode, or if you don't plan to use categories at all, then using this style will result in waste of resources.
  wxPG_EX_NO_FLAT_TOOLBAR | Extended window style that sets wxPropertyGridManager tool bar to not use flat style.
  wxPG_EX_MODE_BUTTONS | Shows alphabetic/categoric mode buttons from tool bar.
  wxPG_EX_HELP_AS_TOOLTIPS | Show property help strings as tool tips instead as text on the status bar. You can set the help strings using SetPropertyHelpString member function.
  wxPG_EX_NATIVE_DOUBLE_BUFFERING | Allows relying on native double-buffering.
  wxPG_EX_AUTO_UNSPECIFIED_VALUES | Set this style to let user have ability to set values of properties to unspecified state. Same as setting wxPG_PROP_AUTO_UNSPECIFIED for all properties.
  wxPG_EX_WRITEONLY_BUILTIN_ATTRIBUTES | If this style is used, built-in attributes (such as wxPG_FLOAT_PRECISION and wxPG_STRING_PASSWORD) are not stored into property's attribute storage (thus they are not readable). Note that this option is global, and applies to all wxPG property containers.
  wxPG_EX_HIDE_PAGE_BUTTONS | Hides page selection buttons from tool bar.
  wxPG_EX_MULTIPLE_SELECTION | Allows multiple properties to be selected by user (by pressing SHIFT when clicking on a property, or by dragging with left mouse button down). You can get array of selected properties with wxPropertyGridInterface::GetSelectedProperties(). In multiple selection mode wxPropertyGridInterface::GetSelection() returns property which has editor active (usually the first one selected). Other useful member functions are ClearSelection(), AddToSelection() and RemoveFromSelection().
  wxPG_EX_ENABLE_TLP_TRACKING | This enables top-level window tracking which allows wxPropertyGrid to notify the application of last-minute property value changes by user. This style is not enabled by default because it may cause crashes when wxPropertyGrid is used in with wxAUI or similar system. Remarks: If you are not in fact using any system that may change wxPropertyGrid's top-level parent window on its own, then you are recommended to enable this style.
  wxPG_EX_NO_TOOLBAR_DIVIDER | Don't show divider above toolbar, on Windows.
  wxPG_EX_TOOLBAR_SEPARATOR | Show a separator below the toolbar.

enum wxPG_KEYBOARD_ACTIONS

## wxPropertyGrid Action Identifiers

These are used with wxPropertyGrid::AddActionTrigger() and wxPropertyGrid::ClearActionTriggers().

Enumerator:

  wxPG_ACTION_INVALID |
  wxPG_ACTION_NEXT_PROPERTY | Select the next property.
  wxPG_ACTION_PREV_PROPERTY | Select the previous property.
  wxPG_ACTION_EXPAND_PROPERTY | Expand the selected property, if it has child items.
  wxPG_ACTION_COLLAPSE_PROPERTY | Collapse the selected property, if it has child items.
  wxPG_ACTION_CANCEL_EDIT | Cancel and undo any editing done in the currently active property editor.
  wxPG_ACTION_EDIT | Move focus to the editor control of the currently selected property.
  wxPG_ACTION_PRESS_BUTTON | Causes editor's button (if any) to be pressed.
  wxPG_ACTION_MAX |

enum wxPG_VALIDATION_FAILURE_BEHAVIOR_FLAGS

## wxPropertyGrid Validation Failure behaviour Flags

Enumerator:

  wxPG_VFB_STAY_IN_PROPERTY | Prevents user from leaving property unless value is valid. If this behaviour flag is not used, then value change is instead cancelled.
  wxPG_VFB_BEEP | Calls wxBell() on validation failure.
  wxPG_VFB_MARK_CELL | Cell with invalid value will be marked (with red colour).
  wxPG_VFB_SHOW_MESSAGE | Display a text message explaining the situation. To customize the way the message is displayed, you need to reimplement wxPropertyGrid::DoShowPropertyError() in a derived class. Default behaviour is to display the text on the top-level frame's status bar, if present, and otherwise using wxMessageBox.
  wxPG_VFB_SHOW_MESSAGEBOX | Similar to wxPG_VFB_SHOW_MESSAGE, except always displays the message using wxMessageBox.
  wxPG_VFB_SHOW_MESSAGE_ON_STATUSBAR | Similar to wxPG_VFB_SHOW_MESSAGE, except always displays the message on the status bar (when present - you can reimplement wxPropertyGrid::GetStatusBar() in a derived class to specify this yourself).
  wxPG_VFB_DEFAULT | Defaults.

enum wxPG_WINDOW_STYLES

## wxPropertyGrid Window Styles

SetWindowStyleFlag method can be used to modify some of these at run-time.

Enumerator:

  wxPG_AUTO_SORT | This will cause Sort() automatically after an item is added. When inserting a lot of items in this mode, it may make sense to use Freeze() before operations and Thaw() afterwards to increase performance.
  wxPG_HIDE_CATEGORIES | Categories are not initially shown (even if added). IMPORTANT NOTE: If you do not plan to use categories, then this style will waste resources. This flag can also be changed using wxPropertyGrid::EnableCategories method.
  wxPG_ALPHABETIC_MODE | This style combines non-categoric mode and automatic sorting.
  wxPG_BOLD_MODIFIED | Modified values are shown in bold font. Changing this requires Refresh() to show changes.
  wxPG_SPLITTER_AUTO_CENTER | When wxPropertyGrid is resized, splitter moves to the center. This behaviour stops once the user manually moves the splitter.
  wxPG_TOOLTIPS | Display tool tips for cell text that cannot be shown completely. If wxUSE_TOOLTIPS is 0, then this doesn't have any effect.
  wxPG_HIDE_MARGIN | Disables margin and hides all expand/collapse buttons that would appear outside the margin (for sub-properties). Toggling this style automatically expands all collapsed items.
  wxPG_STATIC_SPLITTER | This style prevents user from moving the splitter.
  wxPG_STATIC_LAYOUT | Combination of other styles that make it impossible for user to modify the layout.
  wxPG_LIMITED_EDITING | Disables wxTextCtrl based editors for properties which can be edited in another way. Equals calling wxPropertyGrid::LimitPropertyEditing() for all added properties.
  wxPG_TOOLBAR | wxPropertyGridManager only: Show tool bar for mode and page selection.
  wxPG_DESCRIPTION | wxPropertyGridManager only: Show adjustable text box showing description or help text, if available, for currently selected property.
  wxPG_NO_INTERNAL_BORDER | wxPropertyGridManager only: don't show an internal border around the property grid. Recommended if you use a header.
