Texture

gdk.texture.Texture is the basic element used to refer to pixel data.

It is primarily meant for pixel data that will not change over multiple frames, and will be used for a long time.

There are various ways to create gdk.texture.Texture objects from a gdkpixbuf.pixbuf.Pixbuf, or from bytes stored in memory, a file, or a gio.resource.Resource.

The ownership of the pixel data is transferred to the gdk.texture.Texture instance; you can only make a copy of it, via gdk.texture.Texture.download.

gdk.texture.Texture is an immutable object: That means you cannot change anything about it other than increasing the reference count via gobject.object.ObjectG.ref_, and consequently, it is a thread-safe object.

From `mixin IconT!()`

equal bool equal(gio.icon.Icon icon2): Checks if two icons are equal.
hash uint hash(): Gets a hash for an icon.
serialize glib.variant.VariantG serialize(): Serializes a #GIcon into a #GVariant. An equivalent #GIcon can be retrieved back by calling gio.icon.Icon.deserialize on the returned value. As serialization will avoid using raw icon data when possible, it only makes sense to transfer the #GVariant between processes on the same machine, (as opposed to over the network), and within the same file system namespace.
toString_ string toString_(): Generates a textual representation of icon that can be used for serialization such as when passing icon to a different process or saving it to persistent storage. Use gio.icon.Icon.newForString to get icon back from the returned string.

From `mixin LoadableIconT!()`

load gio.input_stream.InputStream load(int size, string type, gio.cancellable.Cancellable cancellable): Loads a loadable icon. For the asynchronous version of this function, see gio.loadable_icon.LoadableIcon.loadAsync.
loadAsync void loadAsync(int size, gio.cancellable.Cancellable cancellable, gio.types.AsyncReadyCallback callback): Loads an icon asynchronously. To finish this function, see gio.loadable_icon.LoadableIcon.loadFinish. For the synchronous, blocking version of this function, see gio.loadable_icon.LoadableIcon.load.
loadFinish gio.input_stream.InputStream loadFinish(gio.async_result.AsyncResult res, string type): Finishes an asynchronous icon load started in gio.loadable_icon.LoadableIcon.loadAsync.

From ObjectG

setGObject void setGObject(void* cObj, Flag!"Take" take): Set the GObject of a D ObjectG wrapper.
cPtr void* cPtr(Flag!"Dup" dup): Get a pointer to the underlying C object.
ref_ void* ref_(void* gObj): Calls g_object_ref() on a GObject.
unref unref(void* gObj): Calls g_object_unref() on a GObject.
getType GType getType(): Get the GType of an object.
gType GType gType [@property getter]: GObject GType property.
self ObjectG self(): Convenience method to return this cast to a type. For use in D with statements.
getDObject T getDObject(void* cptr, Flag!"Take" take): Template to get the D object from a C GObject and cast it to the given D object type.
connectSignalClosure ulong connectSignalClosure(string signalDetail, DClosure closure, Flag!"After" after): Connect a D closure to an object signal.
setProperty void setProperty(string propertyName, T val): Template for setting a GObject property.
getProperty T getProperty(string propertyName): Template for getting a GObject property.
compatControl size_t compatControl(size_t what, void* data)
bindProperty gobject.binding.Binding bindProperty(string sourceProperty, gobject.object.ObjectG target, string targetProperty, gobject.types.BindingFlags flags): Creates a binding between source_property on source and target_property on target.
bindPropertyFull gobject.binding.Binding bindPropertyFull(string sourceProperty, gobject.object.ObjectG target, string targetProperty, gobject.types.BindingFlags flags, gobject.closure.Closure transformTo, gobject.closure.Closure transformFrom): Creates a binding between source_property on source and target_property on target, allowing you to set the transformation functions to be used by the binding.
forceFloating void forceFloating(): This function is intended for #GObject implementations to re-enforce a floating[floating-ref] object reference. Doing this is seldom required: all #GInitiallyUnowneds are created with a floating reference which usually just needs to be sunken by calling gobject.object.ObjectG.refSink.
freezeNotify void freezeNotify(): Increases the freeze count on object. If the freeze count is non-zero, the emission of "notify" signals on object is stopped. The signals are queued until the freeze count is decreased to zero. Duplicate notifications are squashed so that at most one #GObject::notify signal is emitted for each property modified while the object is frozen.
getData void* getData(string key): Gets a named field from the objects table of associations (see gobject.object.ObjectG.setData).
getProperty void getProperty(string propertyName, gobject.value.Value value): Gets a property of an object.
getQdata void* getQdata(glib.types.Quark quark): This function gets back user data pointers stored via gobject.object.ObjectG.setQdata.
getv void getv(string[] names, gobject.value.Value[] values): Gets n_properties properties for an object. Obtained properties will be set to values. All properties must be valid. Warnings will be emitted and undefined behaviour may result if invalid properties are passed in.
isFloating bool isFloating(): Checks whether object has a floating[floating-ref] reference.
notify void notify(string propertyName): Emits a "notify" signal for the property property_name on object.
notifyByPspec void notifyByPspec(gobject.param_spec.ParamSpec pspec): Emits a "notify" signal for the property specified by pspec on object.
refSink gobject.object.ObjectG refSink(): Increase the reference count of object, and possibly remove the floating[floating-ref] reference, if object has a floating reference.
runDispose void runDispose(): Releases all references to other objects. This can be used to break reference cycles.
setData void setData(string key, void* data): Each object carries around a table of associations from strings to pointers. This function lets you set an association.
setProperty void setProperty(string propertyName, gobject.value.Value value): Sets a property on an object.
stealData void* stealData(string key): Remove a specified datum from the object's data associations, without invoking the association's destroy handler.
stealQdata void* stealQdata(glib.types.Quark quark): This function gets back user data pointers stored via gobject.object.ObjectG.setQdata and removes the data from object without invoking its destroy() function (if any was set). Usually, calling this function is only required to update user data pointers with a destroy notifier, for example:
thawNotify void thawNotify(): Reverts the effect of a previous call to gobject.object.ObjectG.freezeNotify. The freeze count is decreased on object and when it reaches zero, queued "notify" signals are emitted.
watchClosure void watchClosure(gobject.closure.Closure closure): This function essentially limits the life time of the closure to the life time of the object. That is, when the object is finalized, the closure is invalidated by calling gobject.closure.Closure.invalidate on it, in order to prevent invocations of the closure with a finalized (nonexisting) object. Also, gobject.object.ObjectG.ref_ and gobject.object.ObjectG.unref are added as marshal guards to the closure, to ensure that an extra reference count is held on object during invocation of the closure. Usually, this function will be called on closures that use this object as closure data.
connectNotify ulong connectNotify(string detail, T callback, Flag!"After" after): Connect to Notify signal.

From Paintable

newEmpty gdk.paintable.Paintable newEmpty(int intrinsicWidth, int intrinsicHeight): Returns a paintable that has the given intrinsic size and draws nothing.

serialize glib.variant.VariantG serialize(): Serializes a #GIcon into a #GVariant. An equivalent #GIcon can be retrieved back by calling gio.icon.Icon.deserialize on the returned value.
