/** @class wxPGProperty
wxPGProperty is base class for all wxPropertyGrid properties. In
sections below we cover few related topics.
@li @ref pgproperty_properties
@li @ref pgproperty_creating
@section pgproperty_properties Supplied Ready-to-use Property Classes
Here is a list and short description of supplied fully-functional
property classes. They are located in either props.h or advprops.h.
@li @ref wxArrayStringProperty
@li @ref wxBoolProperty
@li @ref wxColourProperty
@li @ref wxCursorProperty
@li @ref wxDateProperty
@li @ref wxDirProperty
@li @ref wxEditEnumProperty
@li @ref wxEnumProperty
@li @ref wxFileProperty
@li @ref wxFlagsProperty
@li @ref wxFloatProperty
@li @ref wxFontProperty
@li @ref wxImageFileProperty
@li @ref wxIntProperty
@li @ref wxLongStringProperty
@li @ref wxMultiChoiceProperty
@li @ref wxPropertyCategory
@li @ref wxStringProperty
@li @ref wxSystemColourProperty
@li @ref wxUIntProperty
@subsection wxPropertyCategory
Not an actual property per se, but a header for a group of properties.
Regardless inherits from wxPGProperty.
@subsection wxStringProperty
Simple string property. wxPG_STRING_PASSWORD attribute may be used
to echo value as asterisks and use wxTE_PASSWORD for wxTextCtrl.
@remarks
* wxStringProperty has a special trait: if it has value of "<composed>",
and also has child properties, then its displayed value becomes
composition of child property values, similar as with wxFontProperty,
for instance.
@subsection wxIntProperty
Like wxStringProperty, but converts text to a signed long integer.
wxIntProperty seamlessly supports 64-bit integers (ie. wxLongLong).
@subsection wxUIntProperty
Like wxIntProperty, but displays value as unsigned int. To set
the prefix used globally, manipulate wxPG_UINT_PREFIX string attribute.
To set the globally used base, manipulate wxPG_UINT_BASE int
attribute. Regardless of current prefix, understands (hex) values starting
with both "0x" and "$".
wxUIntProperty seamlessly supports 64-bit unsigned integers (ie.
wxULongLong).
@subsection wxFloatProperty
Like wxStringProperty, but converts text to a double-precision floating
point. Default float-to-text precision is 6 decimals, but this can be
changed by modifying wxPG_FLOAT_PRECISION attribute.
@subsection wxBoolProperty
Represents a boolean value. wxChoice is used as editor control, by the
default. wxPG_BOOL_USE_CHECKBOX attribute can be set to true inorder to use
check box instead.
@subsection wxLongStringProperty
Like wxStringProperty, but has a button that triggers a small text editor
dialog. Note that in long string values, tabs are represented by "\t" and
line break by "\n".
@subsection wxDirProperty
Like wxLongStringProperty, but the button triggers dir selector instead.
Supported properties (all with string value): wxPG_DIR_DIALOG_MESSAGE.
@subsection wxFileProperty
Like wxLongStringProperty, but the button triggers file selector instead.
Default wildcard is "All files..." but this can be changed by setting
wxPG_FILE_WILDCARD attribute (see wxFileDialog for format details).
Attribute wxPG_FILE_SHOW_FULL_PATH can be set to false inorder to show
only the filename, not the entire path.
@subsection wxEnumProperty
Represents a single selection from a list of choices -
wxOwnerDrawnComboBox is used to edit the value.
@subsection wxFlagsProperty
Represents a bit set that fits in a long integer. wxBoolProperty
sub-properties are created for editing individual bits. Textctrl is created
to manually edit the flags as a text; a continous sequence of spaces,
commas and semicolons is considered as a flag id separator.
<b>Note: </b> When changing "choices" (ie. flag labels) of wxFlagsProperty,
you will need to use SetPropertyChoices - otherwise they will not get
updated properly.
@subsection wxArrayStringProperty
Allows editing of a list of strings in wxTextCtrl and in a separate dialog.
@subsection wxDateProperty
wxDateTime property. Default editor is DatePickerCtrl, altough TextCtrl
should work as well. wxPG_DATE_FORMAT attribute can be used to change
string wxDateTime::Format uses (altough default is recommended as it is
locale-dependant), and wxPG_DATE_PICKER_STYLE allows changing window
style given to DatePickerCtrl (default is wxDP_DEFAULT|wxDP_SHOWCENTURY).
@subsection wxEditEnumProperty
Represents a string that can be freely edited or selected from list of
choices - custom combobox control is used to edit the value.
@subsection wxMultiChoiceProperty
Allows editing a multiple selection from a list of strings. This is
property is pretty much built around concept of wxMultiChoiceDialog.
It uses wxArrayString value.
@subsection wxImageFileProperty
Like wxFileProperty, but has thumbnail of the image in front of
the filename and autogenerates wildcard from available image handlers.
@subsection wxColourProperty
<b>Useful alternate editor:</b> Choice.
Represents wxColour. wxButton is used to trigger a colour picker dialog.
@subsection wxFontProperty
Represents wxFont. Various sub-properties are used to edit individual
subvalues.
@subsection wxSystemColourProperty
Represents wxColour and a system colour index. wxChoice is used to edit
the value. Drop-down list has color images. Note that value type
is wxColourPropertyValue instead of wxColour.
@code
class wxColourPropertyValue : public wxObject
{
public:
// An integer value relating to the colour, and which exact
// meaning depends on the property with which it is used.
//
// For wxSystemColourProperty:
// Any of wxSYS_COLOUR_XXX, or any web-colour (use
// wxPG_TO_WEB_COLOUR macro - (currently unsupported) ),
// or wxPG_COLOUR_CUSTOM.
wxUint32 m_type;
// Resulting colour. Should be correct regardless of type.
wxColour m_colour;
};
@endcode
@subsection wxCursorProperty
Represents a wxCursor. wxChoice is used to edit the value.
Drop-down list has cursor images under some (wxMSW) platforms.
@section pgproperty_creating Creating Custom Properties
New properties can be created by subclassing wxPGProperty or one
of the provided property classes, and (re)implementing necessary
member functions. Below, each virtual member function has ample
documentation about its purpose and any odd details which to keep
in mind.
Here is a very simple 'template' code:
@code
class MyProperty : public wxPGProperty
{
public:
// All arguments of ctor must have a default value -
// use wxPG_LABEL for label and name
MyProperty( const wxString& label = wxPG_LABEL,
const wxString& name = wxPG_LABEL,
const wxString& value = wxEmptyString )
{
// m_value is wxVariant
m_value = value;
}
virtual ~MyProperty() { }
const wxPGEditor* DoGetEditorClass() const
{
// Determines editor used by property.
// You can replace 'TextCtrl' below with any of these
// builtin-in property editor identifiers: Choice, ComboBox,
// TextCtrlAndButton, ChoiceAndButton, CheckBox, SpinCtrl,
// DatePickerCtrl.
return wxPGEditor_TextCtrl;
}
virtual wxString GetValueAsString( int argFlags ) const
{
// TODO: Return property value in string format
}
virtual bool StringToValue( wxVariant& variant,
const wxString& text,
int argFlags )
{
// TODO: Adapt string to property value.
}
protected:
};
@endcode
Since wxPGProperty derives from wxObject, you can use standard
DECLARE_DYNAMIC_CLASS and IMPLEMENT_DYNAMIC_CLASS macros. From the
above example they were omitted for sake of simplicity, and besides,
they are only really needed if you need to use wxRTTI with your
property class.
You can change the 'value type' of a property by simply assigning different
type of variant with SetValue. <b>It is mandatory to implement
wxVariantData class for all data types used as property values.</b> Also,
it is further recommended to derive your class from wxPGVariantData, like
this:
@code
// In header file:
// (replace DECL with required data declaration, use
// wxEMPTY_PARAMETER_VALUE if none)
WX_PG_DECLARE_VARIANT_DATA(wxPGVariantMyDataClass, MyDataClass, DECL)
// In sources file:
WX_PG_IMPLEMENT_VARIANT_DATA(wxPGVariantMyDataClass, MyDataClass)
@endcode
@library{wxpropgrid}

Override to paint an image in front of the property value text or

If property's OnMeasureImage() returns size that has height != 0 but
less than row height ( < 0 has special meanings), wxPropertyGrid calls
this method to draw a custom image in a limited area in front of the
editor control or value text/graphics, and if control has drop-down
list, then the image is drawn there as well (even in the case
OnMeasureImage() returned higher height than row height).
NOTE: Following applies when OnMeasureImage() returns a "flexible"
height ( using wxPG_FLEXIBLE_SIZE(W,H) macro), which implies variable
height items: If rect.x is < 0, then this is a measure item call, which
means that dc is invalid and only thing that should be done is to set
paintdata.m_drawnHeight to the height of the image of item at index
paintdata.m_choiceItem. This call may be done even as often as once
every drop-down popup show.
@param dc
wxDC to paint on.
@param rect
Box reserved for custom graphics. Includes surrounding rectangle,
if any. If x is < 0, then this is a measure item call (see above).
@param paintdata
wxPGPaintData structure with much useful data.
@remarks
- You can actually exceed rect width, but if you do so then
paintdata.m_drawnWidth must be set to the full width drawn in
pixels.
- Due to technical reasons, rect's height will be default even if
custom height was reported during measure call.
- Brush is guaranteed to be default background colour. It has been
already used to clear the background of area being painted. It
can be modified.
- Pen is guaranteed to be 1-wide 'black' (or whatever is the proper
colour) pen for drawing framing rectangle. It can be changed as
well.
