GLTextureBuilder

gdk.gltexture_builder.GLTextureBuilder is a builder used to construct gdk.texture.Texture objects from GL textures.

The operation is quite simple: Create a texture builder, set all the necessary properties - keep in mind that the properties gdk.gltexture_builder.GLTextureBuilder.GLContext, gdk.gltexture_builder.GLTextureBuilder.guint, gdk.gltexture_builder.GLTextureBuilder.gint, and gdk.gltexture_builder.GLTextureBuilder.gint are mandatory - and then call gdk.gltexture_builder.GLTextureBuilder.build to create the new texture.

gdk.gltexture_builder.GLTextureBuilder can be used for quick one-shot construction of textures as well as kept around and reused to construct multiple textures.

Functions

build gdk.texture.Texture build(glib.types.DestroyNotify destroy, void* data): Builds a new gdk.texture.Texture with the values set up in the builder.
getContext gdk.glcontext.GLContext getContext(): Gets the context previously set via gdk.gltexture_builder.GLTextureBuilder.setContext or null if none was set.
getFormat gdk.types.MemoryFormat getFormat(): Gets the format previously set via gdk.gltexture_builder.GLTextureBuilder.setFormat.
getHasMipmap bool getHasMipmap(): Gets whether the texture has a mipmap.
getHeight int getHeight(): Gets the height previously set via gdk.gltexture_builder.GLTextureBuilder.setHeight or 0 if the height wasn't set.
getId uint getId(): Gets the texture id previously set via gdk.gltexture_builder.GLTextureBuilder.setId or 0 if the id wasn't set.
getSync void* getSync(): Gets the GLsync previously set via gdk.gltexture_builder.GLTextureBuilder.setSync.
getUpdateRegion cairo.region.Region getUpdateRegion(): Gets the region previously set via gdk.gltexture_builder.GLTextureBuilder.setUpdateRegion or null if none was set.
getUpdateTexture gdk.texture.Texture getUpdateTexture(): Gets the texture previously set via gdk.gltexture_builder.GLTextureBuilder.setUpdateTexture or null if none was set.
getWidth int getWidth(): Gets the width previously set via gdk.gltexture_builder.GLTextureBuilder.setWidth or 0 if the width wasn't set.
setContext void setContext(gdk.glcontext.GLContext context): Sets the context to be used for the texture. This is the context that owns the texture.
setFormat void setFormat(gdk.types.MemoryFormat format): Sets the format of the texture. The default is gdk.types.MemoryFormat.R8g8b8a8Premultiplied.
setHasMipmap void setHasMipmap(bool hasMipmap): Sets whether the texture has a mipmap. This allows the renderer and other users of the generated texture to use a higher quality downscaling.
setHeight void setHeight(int height): Sets the height of the texture.
setId void setId(uint id): Sets the texture id of the texture. The texture id must remain unmodified until the texture was finalized. See gdk.gltexture_builder.GLTextureBuilder.build for a longer discussion.
setSync void setSync(void* sync): Sets the GLSync object to use for the texture.
setUpdateRegion void setUpdateRegion(cairo.region.Region region): Sets the region to be updated by this texture. Together with propertyGdk.GLTextureBuilder:update-texture this describes an update of a previous texture.
setUpdateTexture void setUpdateTexture(gdk.texture.Texture texture): Sets the texture to be updated by this texture. See gdk.gltexture_builder.GLTextureBuilder.setUpdateRegion for an explanation.
setWidth void setWidth(int width): Sets the width of the texture.

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.
