@section propgrid_basics Creating and Populating wxPropertyGrid
wxPropertyGrid is usually populated with lines like this:
@code
- pg->Append( new wxStringProperty(wxT("Label"),wxT("Name"),wxT("Initial Value")) );
+ pg->Append( new wxStringProperty("Label", "Name", "Initial Value") );
@endcode
Naturally, wxStringProperty is a property class. Only the first function argument (label)
@code
// Add int property
- pg->Append( new wxIntProperty(wxT("IntProperty"), wxPG_LABEL, 12345678) );
+ pg->Append( new wxIntProperty("IntProperty", wxPG_LABEL, 12345678) );
// Add float property (value type is actually double)
- pg->Append( new wxFloatProperty(wxT("FloatProperty"), wxPG_LABEL, 12345.678) );
+ pg->Append( new wxFloatProperty("FloatProperty", wxPG_LABEL, 12345.678) );
// Add a bool property
- pg->Append( new wxBoolProperty(wxT("BoolProperty"), wxPG_LABEL, false) );
+ pg->Append( new wxBoolProperty("BoolProperty", wxPG_LABEL, false) );
// A string property that can be edited in a separate editor dialog.
- pg->Append( new wxLongStringProperty(wxT("LongStringProperty"),
+ pg->Append( new wxLongStringProperty("LongStringProperty",
wxPG_LABEL,
- wxT("This is much longer string than the ")
- wxT("first one. Edit it by clicking the button.")));
+ "This is much longer string than the "
+ "first one. Edit it by clicking the button."));
// String editor with dir selector button.
- pg->Append( new wxDirProperty(wxT("DirProperty"), wxPG_LABEL, ::wxGetUserHome()) );
+ pg->Append( new wxDirProperty("DirProperty", wxPG_LABEL, ::wxGetUserHome()) );
// wxArrayStringProperty embeds a wxArrayString.
- pg->Append( new wxArrayStringProperty(wxT("Label of ArrayStringProperty"),
- wxT("NameOfArrayStringProp")));
+ pg->Append( new wxArrayStringProperty("Label of ArrayStringProperty",
+ "NameOfArrayStringProp"));
// A file selector property.
- pg->Append( new wxFileProperty(wxT("FileProperty"), wxPG_LABEL, wxEmptyString) );
+ pg->Append( new wxFileProperty("FileProperty", wxPG_LABEL, wxEmptyString) );
// Extra: set wild card for file property (format same as in wxFileDialog).
- pg->SetPropertyAttribute( wxT("FileProperty"),
+ pg->SetPropertyAttribute( "FileProperty",
wxPG_FILE_WILDCARD,
- wxT("All files (*.*)|*.*") );
+ "All files (*.*)|*.*" );
@endcode
@code
// Add a file selector property.
- wxPGPropety* prop = pg->Append( new wxFileProperty(wxT("FileProperty"),
- wxPG_LABEL,
- wxEmptyString) );
+ wxPGProperty* prop = pg->Append( new wxFileProperty("FileProperty",
+ wxPG_LABEL,
+ wxEmptyString) );
// Valid: Set wild card by name
- pg->SetPropertyAttribute( wxT("FileProperty"),
+ pg->SetPropertyAttribute( "FileProperty",
wxPG_FILE_WILDCARD,
- wxT("All files (*.*)|*.*") );
+ "All files (*.*)|*.*" );
// Also Valid: Set wild card by property pointer
pg->SetPropertyAttribute( prop,
wxPG_FILE_WILDCARD,
- wxT("All files (*.*)|*.*") );
+ "All files (*.*)|*.*" );
@endcode
Using pointer is faster, since it doesn't require hash map lookup. Anyway,
@code
// One way to add category (similar to how other properties are added)
- pg->Append( new wxPropertyCategory(wxT("Main")) );
+ pg->Append( new wxPropertyCategory("Main") );
// All these are added to "Main" category
- pg->Append( new wxStringProperty(wxT("Name")) );
- pg->Append( new wxIntProperty(wxT("Age"),wxPG_LABEL,25) );
- pg->Append( new wxIntProperty(wxT("Height"),wxPG_LABEL,180) );
- pg->Append( new wxIntProperty(wxT("Weight")) );
+ pg->Append( new wxStringProperty("Name") );
+ pg->Append( new wxIntProperty("Age",wxPG_LABEL,25) );
+ pg->Append( new wxIntProperty("Height",wxPG_LABEL,180) );
+ pg->Append( new wxIntProperty("Weight") );
// Another one
- pg->Append( new wxPropertyCategory(wxT("Attributes")) );
+ pg->Append( new wxPropertyCategory("Attributes") );
// All these are added to "Attributes" category
- pg->Append( new wxIntProperty(wxT("Intelligence")) );
- pg->Append( new wxIntProperty(wxT("Agility")) );
- pg->Append( new wxIntProperty(wxT("Strength")) );
+ pg->Append( new wxIntProperty("Intelligence") );
+ pg->Append( new wxIntProperty("Agility") );
+ pg->Append( new wxIntProperty("Strength") );
@endcode
Sample:
@code
- wxPGProperty* carProp = pg->Append(new wxStringProperty(wxT("Car"),
+ wxPGProperty* carProp = pg->Append(new wxStringProperty("Car",
wxPG_LABEL,
- wxT("<composed>")));

- pg->AppendIn(carProp, new wxStringProperty(wxT("Model"),
+ pg->AppendIn(carProp, new wxStringProperty("Model",

- pg->AppendIn(carProp, new wxIntProperty(wxT("Engine Size (cc)"),
+ pg->AppendIn(carProp, new wxIntProperty("Engine Size (cc)",
wxPG_LABEL,
5707) );
wxPGProperty* speedsProp = pg->AppendIn(carProp,
- new wxStringProperty(wxT("Speeds"),
+ new wxStringProperty("Speeds",
wxPG_LABEL,
- wxT("<composed>")));
+ "<composed>"));
- pg->AppendIn( speedsProp, new wxIntProperty(wxT("Max. Speed (mph)"),
+ pg->AppendIn( speedsProp, new wxIntProperty("Max. Speed (mph)",
wxPG_LABEL,290) );
- pg->AppendIn( speedsProp, new wxFloatProperty(wxT("0-100 mph (sec)"),
+ pg->AppendIn( speedsProp, new wxFloatProperty("0-100 mph (sec)",
wxPG_LABEL,3.9) );
- pg->AppendIn( speedsProp, new wxFloatProperty(wxT("1/4 mile (sec)"),
+ pg->AppendIn( speedsProp, new wxFloatProperty("1/4 mile (sec)",
wxPG_LABEL,8.6) );
// This is how child property can be referred to by name
- pg->SetPropertyValue( wxT("Car.Speeds.Max. Speed (mph)"), 300 );
+ pg->SetPropertyValue( "Car.Speeds.Max. Speed (mph)", 300 );
- pg->AppendIn(carProp, new wxIntProperty(wxT("Price ($)"),
+ pg->AppendIn(carProp, new wxIntProperty("Price ($)",
wxPG_LABEL,
300000) );

wxArrayInt arrIds;

- pg->Append( new wxEnumProperty(wxT("Diet"),

wxPG_LABEL,

arrIds,
@code

@section propgrid_processingvalues Processing Property Values
-Properties store their values internally in wxVariant. You can obtain
-this value using wxPGProperty::GetValue() or wxPropertyGridInterface::
-GetPropertyValue().
-
-If you wish to obtain property value in specific data type, you can
-call various getter functions, such as wxPropertyGridInterface::
-GetPropertyValueAsString(), which, as name might say, returns property
-value's string representation. While this particular function is very
-safe to use for any kind of property, some might display error message
-if property value is not in compatible enough format. For instance,
-wxPropertyGridInterface::GetPropertyValueAsLongLong() will support
-long as well as wxLongLong, but GetPropertyValueAsArrayString() only
-supports wxArrayString and nothing else.
-
-In any case, you will need to take extra care when dealing with
-raw wxVariant values. For instance, wxIntProperty and wxUIntProperty,
-store value internally as wx(U)LongLong when number doesn't fit into
-standard long type. Using << operator to get wx(U)LongLong from wxVariant
-is customized to work quite safely with various types of variant data.
-
-You may have noticed that properties store, in wxVariant, values of many
-types which are not natively supported by it. Custom wxVariantDatas
-are therefore implemented and << and >> operators implemented to
-convert data from and to wxVariant.
+Properties store their values internally as wxVariant, but is also possible to
+obtain them as wxAny, using implicit conversion. You can get property
+values with wxPGProperty::GetValue() and
+wxPropertyGridInterface::GetPropertyValue().
+
+Below is a code example which handles wxEVT_PG_CHANGED event:
+
+@code
+
+void MyWindowClass::OnPropertyGridChanged(wxPropertyGridEvent& event)
+{
+ wxPGProperty* property = event.GetProperty();
+
+ // Do nothing if event did not have associated property
+ if ( !property )
+ return;
+
+ // GetValue() returns wxVariant, but it is converted transparently to
+ // wxAny
+ wxAny value = property->GetValue();
+
+ // Also, handle the case where property value is unspecified
+ if ( value.IsNull() )
+ return;
+
+ // Handle changes in values, as needed
+ if ( property.GetName() == "MyStringProperty" )
+ OnMyStringPropertyChanged(value.As<wxString>());
+ else if ( property.GetName() == "MyColourProperty" )
+ OnMyColourPropertyChanged(value.As<wxColour>());
+}
+
+@endcode
+
+You can get a string-representation of property's value using
+wxPGProperty::GetValueAsString() or
+wxPropertyGridInterface::GetPropertyValueAsString(). This particular function
+is very safe to use with any kind of property.
+
+@note There is a one case in which you may want to take extra care when
+ dealing with raw wxVariant values. That is, integer-type properties,
+ such as wxIntProperty and wxUIntProperty, store value internally as
+ wx(U)LongLong when number doesn't fit into standard long type. Using
+ << operator to get wx(U)LongLong from wxVariant is customized to work
+ quite safely with various types of variant data. However, you can also
+ bypass this problem by using wxAny in your code instead of wxVariant.
Note that in some cases property value can be Null variant, which means
that property value is unspecified. This usually occurs only when
@endcode
-<b>wxPython Note:</b> Instead of ++ operator, use Next() method, and instead of
+@beginWxPythonOnly
+PropertyGridInterface has some useful pythonic iterators as attributes.
+@c Properties lets you iterate through all items that are not category
+captions or private children. @c Items lets you iterate through everything
+except private children. Also, there are GetPyIterator() and GetPyVIterator(),
+which return pythonic iterators instead of normal wxPropertyGridIterator.
+
+If you need to use C++ style iterators in wxPython code, note that
+Instead of ++ operator, use Next() method, and instead of
* operator, use GetProperty() method.
+@endWxPythonOnly
GetIterator() only works with wxPropertyGrid and the individual pages
of wxPropertyGridManager. In order to iterate through an arbitrary
wxPGVIterator it;
- for ( it = manager->GetVIterator();
+ for ( it = manager->GetVIterator(wxPG_ITERATE_ALL);
!it.AtEnd();
it.Next() )
{
to obtain its topmost non-category parent (useful, if you have deeply nested
properties).
+@section propgrid_tooltipandhint Help String, Hint and Tool Tips
+
+For each property you can specify two different types of help text. First,
+you can use wxPropertyGridInterface::SetPropertyHelpString() or
+wxPGProperty::SetHelpString() to set property's help text. Second, you
+can use wxPGProperty::SetAttribute() to set property's "Hint" attribute.
+
+Difference between hint and help string is that the hint is shown in an empty
+property value cell, while help string is shown either in the description text
+box, as a tool tip, or on the status bar, whichever of these is available.
+
+To enable display of help string as tool tips, you must explicitly use
+the wxPG_EX_HELP_AS_TOOLTIPS extra window style.
@section propgrid_validating Validating Property Values
There are various ways to make sure user enters only correct values. First, you
can use wxValidators similar to as you would with ordinary controls. Use
-wxPropertyGridInterface::SetPropertyValidator() to assign wxValidator to
+wxPropertyGridInterface::SetPropertyValidator() to assign wxValidator to
property.
Second, you can subclass a property and override wxPGProperty::ValidateValue(),
// the value to be validated.
wxVariant pendingValue = event.GetValue();
- if ( property->GetName() == wxT("Font") )
+ if ( property->GetName() == "Font" )
{
// Make sure value is not unspecified
if ( !pendingValue.IsNull() )
font << pendingValue;
// Let's just allow Arial font
- if ( font.GetFaceName() != wxT("Arial") )
+ if ( font.GetFaceName() != "Arial" )
{
event.Veto();
event.SetValidationFailureBehavior(wxPG_VFB_STAY_IN_PROPERTY |
wxPG_VFB_BEEP |
- wxPG_VFB_SHOW_MESSAGE);
+ wxPG_VFB_SHOW_MESSAGEBOX);
}
}
}
In addition, it is possible to control these characteristics for
wxPGChoices list items. See wxPGChoices class reference for more info.
+@section propgrid_keyhandling Customizing Keyboard Handling
+
+There is probably one preference for keyboard handling for every developer
+out there, and as a conveniency control wxPropertyGrid tries to cater for
+that. By the default arrow keys are used for navigating between properties,
+and TAB key is used to move focus between the property editor and the
+first column. When the focus is in the editor, arrow keys usually no longer
+work for navigation since they are consumed by the editor.
+
+There are mainly two functions which you can use this customize things,
+wxPropertyGrid::AddActionTrigger() and wxPropertyGrid::DedicateKey().
+First one can be used to set a navigation event to occur on a specific key
+press and the second is used to divert a key from property editors, making it
+possible for the grid to use keys normally consumed by the focused editors.
+
+For example, let's say you want to have an ENTER-based editing scheme. That
+is, editor is focused on ENTER press and the next property is selected when
+the user finishes editing and presses ENTER again. Code like this would
+accomplish the task:
+
+@code
+ // Have property editor focus on Enter
+ propgrid->AddActionTrigger( wxPG_ACTION_EDIT, WXK_RETURN );
+
+ // Have Enter work as action trigger even when editor is focused
+ propgrid->DedicateKey( WXK_RETURN );
+
+ // Let Enter also navigate to the next property
+ propgrid->AddActionTrigger( wxPG_ACTION_NEXT_PROPERTY, WXK_RETURN );
+
+@endcode
+
+wxPG_ACTION_EDIT is prioritized above wxPG_ACTION_NEXT_PROPERTY so that the
+above code can work without conflicts. For a complete list of available
+actions, see @ref propgrid_keyboard_actions.
+
+Here's another trick. Normally the up and down cursor keys are consumed by
+the focused wxTextCtrl editor and as such can't be used for navigating between
+properties when that editor is focused. However, using DedicateKey() we can
+change this so that instead of the cursor keys moving the caret inside the
+wxTextCtrl, they navigate between adjacent properties. As such:
+
+@code
+ propgrid->DedicateKey(WXK_UP);
+ propgrid->DedicateKey(WXK_DOWN);
+@endcode
+
@section propgrid_customizing Customizing Properties (without sub-classing)
In this section are presented miscellaneous ways to have custom appearance
-and behavior for your properties without all the necessary hassle
+and behaviour for your properties without all the necessary hassle
of sub-classing a property class etc.
@subsection propgrid_customimage Setting Value Image
@code
- wxPGProperty* colProp = new wxColourProperty(wxT("Text Colour"));
+ wxPGProperty* colProp = new wxColourProperty("Text Colour");
pg->Append(colProp);
pg->SetPropertyEditor(colProp, wxPGEditor_TextCtrlAndButton);
For example, if you have a wxFlagsProperty, you can
set its all items to use check box using the following:
@code
- pg->SetPropertyAttribute(wxT("MyFlagsProperty"),wxPG_BOOL_USE_CHECKBOX,true,wxPG_RECURSE);
+ pg->SetPropertyAttribute("MyFlagsProperty", wxPG_BOOL_USE_CHECKBOX, true, wxPG_RECURSE);
@endcode
-
+
Following will set all individual bool properties in your control to
use check box:
-
+
@code
pg->SetPropertyAttributeAll(wxPG_BOOL_USE_CHECKBOX, true);

frame/dialog constructor)
+ Splitter centering behaviour can be customized using
+wxPropertyGridInterface::SetColumnProportion(). Usually it is used to set
+non-equal column proportions, which in essence stops the splitter(s) from
+being 'centered' as such, and instead just auto-resized.

+@section propgrid_compat Changes from wxPropertyGrid 1.4
+
+Version of wxPropertyGrid bundled with wxWidgets 2.9+ has various backward-
+incompatible changes from version 1.4, which had a stable API and will remain
+as the last separate branch.
+
+Note that in general any behaviour-breaking changes should not compile or run
+without warnings or errors.
+
+@subsection propgrid_compat_general General Changes
+
+ - Tab-traversal can no longer be used to travel between properties. Now
+ it only causes focus to move from main grid to editor of selected property.
+ Arrow keys are now your primary means of navigating between properties,
+ with keyboard. This change allowed fixing broken tab traversal on wxGTK
+ (which is open issue in wxPropertyGrid 1.4).
+
+ - wxPG_EX_UNFOCUS_ON_ENTER style is removed and is now default behaviour.
+ That is, when enter is pressed, editing is considered done and focus
+ moves back to the property grid from the editor control.
+
+ - A few member functions were removed from wxPropertyGridInterface.
+ Please use wxPGProperty's counterparts from now on.
+
+ - wxPGChoices now has proper Copy-On-Write behaviour.
+
+ - wxPGChoices::SetExclusive() was renamed to AllocExclusive().
+
+ - wxPGProperty::SetPropertyChoicesExclusive() was removed. Instead, use
+ GetChoices().AllocExclusive().
+
+ - wxPGProperty::ClearModifiedStatus() is removed. Please use
+ SetModifiedStatus() instead.
+
+ - wxPropertyGridInterface::GetExpandedProperties() is removed. You should
+ now use wxPropertyGridInterface::GetEditableState() instead.
+
+ - wxPG_EX_DISABLE_TLP_TRACKING is now enabled by default. To get the old
+ behaviour (recommended if you don't use a system that reparents the grid
+ on its own), use the wxPG_EX_ENABLE_TLP_TRACKING extra style.
+
+ - Extended window style wxPG_EX_LEGACY_VALIDATORS was removed.
+
+ - Default property validation failure behaviour has been changed to
+ (wxPG_VFB_MARK_CELL | wxPG_VFB_SHOW_MESSAGEBOX), which means that the
+ cell is marked red and wxMessageBox is shown. This is more user-friendly
+ than the old behaviour, which simply beeped and prevented leaving the
+ property editor until a valid value was entered.
+ - wxPropertyGridManager now has same Get/SetSelection() semantics as
+ wxPropertyGrid.
+
+ - Various wxPropertyGridManager page-related functions now return pointer
+ to the page object instead of index.
+
+ - wxArrayEditorDialog used by wxArrayStringProperty and some sample
+ properties has been renamed to wxPGArrayEditorDialog. Also, it now uses
+ wxEditableListBox for editing.
+
+ - Instead of calling wxPropertyGrid::SetButtonShortcut(), use
+ wxPropertyGrid::SetActionTrigger(wxPG_ACTION_PRESS_BUTTON).
+
+ - wxPGProperty::GetCell() now returns a reference. AcquireCell() was removed.
+
+ - wxPGMultiButton::FinalizePosition() has been renamed to Finalize(),
+ and it has slightly different argument list.
+
+ - wxPropertyGridEvent::HasProperty() is removed. You can use GetProperty()
+ as immediate replacement when checking if event has a property.
+
+ - "InlineHelp" property has been replaced with "Hint".
+
+ - wxPropertyGrid::CanClose() has been removed. Call
+ wxPropertyGridInterface::EditorValidate() instead.
+
+ - wxPGProperty::SetFlag() has been moved to private API. This was done to
+ underline the fact that it was not the preferred method to change a
+ property's state since it never had any desired side-effects. ChangeFlag()
+ still exists for those who really need to achieve the same effect.
+
+ - wxArrayStringProperty default delimiter is now comma (','), and it can
+ be changed by setting the new "Delimiter" attribute.
+
+@subsection propgrid_compat_propdev Property and Editor Sub-classing Changes
+
+ - Confusing custom property macros have been eliminated.
+
+ - Implement wxPGProperty::ValueToString() instead of GetValueAsString().
+
+ - wxPGProperty::ChildChanged() must now return the modified value of
+ whole property instead of writing it back into 'thisValue' argument.
+
+ - Removed wxPropertyGrid::PrepareValueForDialogEditing(). Use
+ wxPropertyGrid::GetPendingEditedValue() instead.
+
+ - wxPGProperty::GetChoiceInfo() is removed, as all properties now carry
+ wxPGChoices instance (protected wxPGProperty::m_choices).
+
+ - Connect() should no longer be called in implementations of
+ wxPGEditor::CreateControls(). wxPropertyGrid automatically passes all
+ events from editor to wxPGEditor::OnEvent() and wxPGProperty::OnEvent(),
+ as appropriate.
+
+ - wxPython: Previously some of the reimplemented member functions needed a
+ 'Py' prefix. This is no longer necessary. For instance, if you previously
+ implemented PyStringToValue() for your custom property, you should now
+ just implement StringToValue().
