Module Summary

Functions for wxXmlResource class

Description

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.

Note that this is a singleton class and you'll never allocate/deallocate it. Just use the static get/0 getter.

wxWidgets docs: wxXmlResource

Data Types

wxXmlResource() = wx:wx_object()

Exports

new() -> wxXmlResource()
new(Options :: [Option]) -> wxXmlResource()

Types

Option = {flags, integer()} | {domain, unicode:chardata()}

Constructor.

new(Filemask, Options :: [Option]) -> wxXmlResource()

Types

Filemask = unicode:chardata()
Option = {flags, integer()} | {domain, unicode:chardata()}

Constructor.

destroy(This :: wxXmlResource()) -> ok

Destructor.

attachUnknownControl(This, Name, Control) -> boolean()

Types

This = wxXmlResource()
Name = unicode:chardata()
Control = wxWindow:wxWindow()
attachUnknownControl(This, Name, Control, Options :: [Option]) ->
                        boolean()

Types

This = wxXmlResource()
Name = unicode:chardata()
Control = wxWindow:wxWindow()
Option = {parent, wxWindow:wxWindow()}

Attaches an unknown control to the given panel/window/dialog.

Unknown controls are used in conjunction with <object class="unknown">.

clearHandlers(This) -> ok

Types

This = wxXmlResource()

Removes all handlers and deletes them (this means that any handlers added using AddHandler() (not implemented in wx) must be allocated on the heap).

compareVersion(This, Major, Minor, Release, Revision) -> integer()

Types

This = wxXmlResource()
Major = Minor = Release = Revision = integer()

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 are equal.

get() -> wxXmlResource()

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

getFlags(This) -> integer()

Types

This = wxXmlResource()

Returns flags, which may be a bitlist of ?wxXmlResourceFlags enumeration values.

getVersion(This) -> integer()

Types

This = wxXmlResource()

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

getXRCID(Str_id) -> integer()

Types

Str_id = unicode:chardata()
getXRCID(Str_id, Options :: [Option]) -> integer()

Types

Str_id = unicode:chardata()
Option = {value_if_not_found, integer()}

Returns a numeric ID that is equivalent to the string ID used in an XML resource.

If an unknown str_id is requested (i.e. other than wxID_XXX or integer), a new record is created which associates the given string with a number.

If value_if_not_found is wxID_NONE, the number is obtained via wx_misc:newId/0. Otherwise value_if_not_found is used.

Macro XRCID(name) is provided for convenient use in event tables.

Note: IDs returned by XRCID() cannot be used with the EVT_*_RANGE macros, because the order in which they are assigned to symbolic name values is not guaranteed.

initAllHandlers(This) -> ok

Types

This = wxXmlResource()

Initializes handlers for all supported controls/windows.

This will make the executable quite big because it forces linking against most of the wxWidgets library.

load(This, Filemask) -> boolean()

Types

This = wxXmlResource()
Filemask = unicode:chardata()

Loads resources from XML files that match given filemask.

Example:

Note: If wxUSE_FILESYS is enabled, this method understands wxFileSystem (not implemented in wx) URLs (see wxFileSystem::FindFirst() (not implemented in wx)).

Note: If you are sure that the argument is name of single XRC file (rather than an URL or a wildcard), use LoadFile() (not implemented in wx) instead.

See: LoadFile() (not implemented in wx), LoadAllFiles() (not implemented in wx)

loadBitmap(This, Name) -> wxBitmap:wxBitmap()

Types

This = wxXmlResource()
Name = unicode:chardata()

Loads a bitmap resource from a file.

loadDialog(This, Parent, Name) -> wxDialog:wxDialog()

Types

This = wxXmlResource()
Parent = wxWindow:wxWindow()
Name = unicode:chardata()

Loads a dialog.

parent points to parent window (if any).

loadDialog(This, Dlg, Parent, Name) -> boolean()

Types

This = wxXmlResource()
Dlg = wxDialog:wxDialog()
Parent = wxWindow:wxWindow()
Name = unicode:chardata()

Loads a dialog.

parent 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:

loadFrame(This, Parent, Name) -> wxFrame:wxFrame()

Types

This = wxXmlResource()
Parent = wxWindow:wxWindow()
Name = unicode:chardata()

Loads a frame from the resource.

parent points to parent window (if any).

loadFrame(This, Frame, Parent, Name) -> boolean()

Types

This = wxXmlResource()
Frame = wxFrame:wxFrame()
Parent = wxWindow:wxWindow()
Name = unicode:chardata()

Loads the contents of a frame onto an existing wxFrame.

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).

loadIcon(This, Name) -> wxIcon:wxIcon()

Types

This = wxXmlResource()
Name = unicode:chardata()

Loads an icon resource from a file.

loadMenu(This, Name) -> wxMenu:wxMenu()

Types

This = wxXmlResource()
Name = unicode:chardata()

Loads menu from resource.

Returns NULL on failure.

loadMenuBar(This, Name) -> wxMenuBar:wxMenuBar()

Types

This = wxXmlResource()
Name = unicode:chardata()

loadMenuBar(This, Parent, Name) -> wxMenuBar:wxMenuBar()

Types

This = wxXmlResource()
Parent = wxWindow:wxWindow()
Name = unicode:chardata()

Loads a menubar from resource.

Returns NULL on failure.

loadPanel(This, Parent, Name) -> wxPanel:wxPanel()

Types

This = wxXmlResource()
Parent = wxWindow:wxWindow()
Name = unicode:chardata()

Loads a panel.

parent points to the parent window.

loadPanel(This, Panel, Parent, Name) -> boolean()

Types

This = wxXmlResource()
Panel = wxPanel:wxPanel()
Parent = wxWindow:wxWindow()
Name = unicode:chardata()

Loads a panel.

parent points to the parent window. This form is used to finish creation of an already existing instance.

loadToolBar(This, Parent, Name) -> wxToolBar:wxToolBar()

Types

This = wxXmlResource()
Parent = wxWindow:wxWindow()
Name = unicode:chardata()

Loads a toolbar.

set(Res) -> wxXmlResource()

Types

Res = wxXmlResource()

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

setFlags(This, Flags) -> ok

Types

This = wxXmlResource()
Flags = integer()

Sets flags (bitlist of ?wxXmlResourceFlags enumeration values).

unload(This, Filename) -> boolean()

Types

This = wxXmlResource()
Filename = unicode:chardata()

This function unloads a resource previously loaded by load/2.

Returns true if the resource was successfully unloaded and false if it hasn't been found in the list of loaded resources.

xrcctrl(Window, Name, Type) -> wx:wx_object()

Types

Window = wxWindow:wxWindow()
Name = string()
Type = atom()

Looks up a control.

Get a control with Name in a window created with XML resources. You can use it to set/get values from controls. The object is type casted to Type. Example:
