wxXmlResource

wxXmlResource

This is the main class for interacting with the XML-based resource system.

The class holds XML resources from one or more .xml files, binary files or zip archive files.

See XML-based resource system overview for details.

Members

wxXmlResource::wxXmlResource

wxXmlResource(const wxString& filemask, int flags = wxXRC_USE_LOCALE)

Constructor.

filemask

The XRC file, archive file, or wildcard specification that will be used to load all resource files inside a zip archive.

flags

wxXRC_USE_LOCALE: translatable strings will be translated via _(). wxXRC_NO_SUBCLASSING: subclass property of object nodes will be ignored (useful for previews in XRC editors).

wxXmlResource(int flags = wxXRC_USE_LOCALE)

Constructor.

flags

wxXRC_USE_LOCALE: translatable strings will be translated via _(). wxXRC_NO_SUBCLASSING: subclass property of object nodes will be ignored (useful for previews in XRC editors).

wxXmlResource::~wxXmlResource

~wxXmlResource()

Destructor.

wxXmlResource::AddHandler

void AddHandler(wxXmlResourceHandler* handler)

Initializes only a specific handler (or custom handler). Convention says that the handler name is equal to the control's name plus 'XmlHandler', for example wxTextCtrlXmlHandler, wxHtmlWindowXmlHandler. The XML resource compiler (wxxrc) can create include file that contains initialization code for all controls used within the resource.

wxXmlResource::AttachUnknownControl

bool AttachUnknownControl(const wxString& name, wxWindow* control, wxWindow* parent = NULL)

Attaches an unknown control to the given panel/window/dialog. Unknown controls are used in conjunction with <object class="unknown">.

wxXmlResource::ClearHandlers

void ClearHandlers()

Removes all handlers.

wxXmlResource::CompareVersion

int CompareVersion(int major, int minor, int release, int revision) const

Compares the XRC version to the argument. Returns -1 if the XRC version is less than the argument, +1 if greater, and 0 if they equal.

wxXmlResource::CreateResFromNode

wxObject* CreateResFromNode(wxXmlNode* node, wxObject* parent, wxObject* instance = NULL)

Creates a resource from information in the given node.

wxXmlResource::DoFindResource

wxXmlNode* DoFindResource(wxXmlNode* parent, const wxString& name, const wxString& classname, bool recursive)

Helper function: finds a resource (calls UpdateResources) and returns a node containing it.

wxXmlResource::FindResource

wxXmlNode* FindResource(const wxString& name, const wxString& classname, bool recursive = false)

Finds a resource (calls UpdateResources) and returns a node containing it.

wxXmlResource::Get

wxXmlResource* Get()

Gets the global resources object or creates one if none exists.

wxXmlResource::GetFlags

int GetFlags()

Returns flags, which may be a bitlist of wxXRC_USE_LOCALE and wxXRC_NO_SUBCLASSING.

wxXmlResource::GetVersion

long GetVersion() const

Returns version information (a.b.c.d = d+ 256*c + 2562*b + 2563*a).

wxXmlResource::GetXRCID

int GetXRCID(const wxChar* str_id)

Returns a numeric ID that is equivalent to the string ID used in an XML resource. To be used in event tables. The macro XRCID(name) is provided for convenience.

wxXmlResource::InitAllHandlers

void InitAllHandlers()

Initializes handlers for all supported controls/windows. This will make the executable quite big because it forces linking against most of the wxWidgets library.

wxXmlResource::Load

bool Load(const wxString& filemask)

Loads resources from XML files that match given filemask. This method understands VFS (see filesys.h).

wxXmlResource::LoadBitmap

wxBitmap LoadBitmap(const wxString& name)

Loads a bitmap resource from a file.

wxXmlResource::LoadDialog

wxDialog* LoadDialog(wxWindow* parent, const wxString& name)

Loads a dialog. dlg points to a parent window (if any).

bool LoadDialog(wxDialog* dlg, wxWindow* parent, const wxString& name)

Loads a dialog. dlg points to parent window (if any).

This form is used to finish creation of an already existing instance (the main reason for this is that you may want to use derived class with a new event table).

Example:

  MyDialog dlg;
  wxTheXmlResource->LoadDialog(&dlg, mainFrame, "my_dialog");
  dlg->ShowModal();

wxXmlResource::LoadFrame

bool LoadFrame(wxFrame* frame, wxWindow* parent, const wxString& name)

Loads a frame.

wxXmlResource::LoadIcon

wxIcon LoadIcon(const wxString& name)

Loads an icon resource from a file.

wxXmlResource::LoadMenu

wxMenu* LoadMenu(const wxString& name)

Loads menu from resource. Returns NULL on failure.

wxXmlResource::LoadMenuBar

wxMenuBar* LoadMenuBar(wxWindow* parent, const wxString& name)

Loads a menubar from resource. Returns NULL on failure.

wxMenuBar* LoadMenuBar(const wxString& name)

Loads a menubar from resource. Returns NULL on failure.

wxXmlResource::LoadPanel

wxPanel* LoadPanel(wxWindow* parent, const wxString& name)

Loads a panel. panel points to parent window (if any).

bool LoadPanel(wxPanel* panel, wxWindow* parent, const wxString& name)

Loads a panel. panel points to parent window (if any). This form is used to finish creation of an already existing instance.

wxXmlResource::LoadToolBar

wxToolBar* LoadToolBar(wxWindow* parent, const wxString& name)

Loads a toolbar.

wxXmlResource::Set

wxXmlResource* Set(wxXmlResource* res)

Sets the global resources object and returns a pointer to the previous one (may be NULL).

wxXmlResource::SetFlags

int SetFlags()

Sets flags (bitlist of wxXRC_USE_LOCALE and wxXRC_NO_SUBCLASSING).

wxXmlResource::UpdateResources

void UpdateResources()

Scans the resources list for unloaded files and loads them. Also reloads files that have been modified since the last load.
