Thanks, I'll test it out when I get a chance. I was able to work around
the issue for now but I imagine I'll need the ability to implement my
own container in the future.
BTW, when I try to create a value I get an error about opCall
Value handleSize = new Value(0);
vs
Value handleSize = Value(0);
I'd rather not create a value on the heap when I only need it locally.
Could you add a way to create the value with the right type to Value?
Even static constructors would work(probably could templatize it).
Although, I'm not sure how much it matters since value itself seems to
allocate on the heap ;/
public this()
{
this(new GValue);
}
But it might help reduce some memory waste.
`Value` is a class so you will need to use `new`.

Hey Mike, I bet you can answer this!
I'd like to extend a widget to add some functionality.
class MyBox : Box
{
protected GtkBox* gtkBox;
import std.typecons;
_gtk.Box Wrapped;
mixin Proxy!Wrapped;
public this(Box b)
{
this.gtkBox = b.getBoxStruct();
super(gtkBox, false);
}
}
Trying something like the above does extend the box, as far as allowing
one to replace it, I think(using the code);
auto b = new MyBox(W1);
auto p = W1.getParent();
auto c = cast(Box)W4;
c.remove(W1);
c.add(b);
So, W4 is the main boxx, W1 is the box inside the main box I replaced
with the new box b.
When running that code, nothing changes, which, assuming we are actually
using the new box, then that is fine.
But I'm pretty sure that gtk never has a clue about `MyBox`? I say this
because I'd like to simply modify the reported sizes of the box.
A gtkBox is not the same as a gtk.Box.
It seems like the best I can do is use a gtk.Container and inherit from
that.
e.g.,
class FixableSizedBox : Container
{
protected GtkContainer* gtkContainer;
import std.typecons;
_gtk.Container Wrapped;
mixin Proxy!Wrapped;
public this(Container b)
{
this.gtkContainer = b.getContainerStruct();
super(gtkContainer, false);
}
}
But even the GtkD container doesn't seem to contain any code to deal
with handling the sizes.
All I'm really looking to do is set the size of a container to whatever
I want.
If you want gtk to know about the functions you override you could use
gtkd.Implement.ImplementCLass.
It's only in master and not completely finished yet, but you could use
it to for example overrride the getPreferredHeight and getPreferredWidth
functions.
I'm not completely clear on what you want to do with the size so they
might not be the correct functions to override.
```
class MyBox : Box
{
import gtkd.Implement;
import gobject.c.functions : g_object_newv;
mixin ImplementClass!GtkBox;
this()
{
//TODO: sort out the constructor.
super(cast(GtkApplication*)g_object_newv(getType(), 0, null), true);
}
override public void getPreferredHeight(out int minimumHeight, out
int naturalHeight)
{
//Set minimumHeight and naturalHeight.
}
override public void getPreferredWidth(out int minimumWidth, out int
naturalWidth)
{
//Set minimumWidth and naturalWidth.
}
}
```
