Class API¶

class wx.xrc.XmlResourceHandler(Object)¶

Possible constructors:

XmlResourceHandler()

SizerXmlHandler is a class for resource handlers capable of creating a Sizer object from an XML node.

Methods¶

__init__(self)¶: Default constructor.

AddStyle(self, name, value)¶

Add a style flag (e.g.

MB_DOCKABLE ) to the list of flags understood by this handler.

Parameters:	name (string) – value (int) –

AddWindowStyles(self)¶: Add styles common to all Window-derived classes.

CanHandle(self, node)¶

Returns True if it understands this node and can create a resource from it, False otherwise.

Parameters:	node (wx.xml.XmlNode) –
Return type:	bool

Note

You must not call any wx.xrc.XmlResourceHandler 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 .

CreateChildren(self, parent, this_hnd_only=False)¶

Parameters:	parent (wx.Object) – this_hnd_only (bool) –

CreateChildrenPrivately(self, parent, rootnode=None)¶

CreateResource(self, node, parent, instance)¶

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 not None it should not create a new instance via ‘new’ but should rather use this one, and call its Create method.

Return type:	wx.Object

DoCreateResource(self)¶

Called from CreateResource after variables were filled.
