## Constructor & Destructor Documentation

wxXmlResourceHandler::wxXmlResourceHandler | ( |  | ) |

Default constructor.

virtual wxXmlResourceHandler::~wxXmlResourceHandler | ( |  | ) |
| virtual

Destructor.

## Member Function Documentation

void wxXmlResourceHandler::AddStyle | ( | const wxString & | name,
|  | int | value
| ) |  |
| protected

Add a style flag (e.g.

`wxMB_DOCKABLE`) to the list of flags understood by this handler.

void wxXmlResourceHandler::AddWindowStyles | ( |  | ) |
| protected

Add styles common to all wxWindow-derived classes.

virtual bool wxXmlResourceHandler::CanHandle | ( | wxXmlNode * | node | ) |
| pure virtual

Returns true if it understands this node and can create a resource from it, false otherwise.

Note
  You must not call any wxXmlResourceHandler methods except IsOfClass() from this method! The instance is not yet initialized with node data at the time CanHandle() is called and it is only safe to operate on node directly or to call IsOfClass().

Implemented in wxSizerXmlHandler.

void wxXmlResourceHandler::CreateChildren | ( | wxObject * | parent,
|  | bool | this_hnd_only = `false`
| ) |  |
| protected

Creates children.

void wxXmlResourceHandler::CreateChildrenPrivately | ( | wxObject * | parent,

| ) |  |

Creates an object (menu, dialog, control, ...) from an XML node.

Should check for validity. parent is a higher-level object (usually window, dialog or panel) that is often necessary to create the resource.

If instance is non-NULL it should not create a new instance via 'new' but should rather use this one, and call its Create method.

virtual wxObject* wxXmlResourceHandler::DoCreateResource | ( |  | ) |
| pure virtual

Called from CreateResource after variables were filled.

Implemented in wxSizerXmlHandler.

wxAnimation* wxXmlResourceHandler::GetAnimation | ( | const wxString & | param = `"animation"` | ) |
