And that (the Tuesday OR Friday part) means it's time for another

Today's topic: Changing the mouse pointer

You'll be thrilled by the heart-shaped point and tickled by the

Anyway. 'Nuff said.

I thought the suggestion was one thread in the Announce forum, 
rather than multiple threads in the Announce forum...rather than 
one thread in the Learn forum.

It's a learning resource, so wouldn't that go here? Or am I 
misinterpreting the intention of the Learn sub-forum?

If you a moderator believes it should move, please feel free.

It's a learning resource, sure, but you're also announcing a new 
blog post. Tricky.

My thinking exactly. (I would have replied with a simple, "Yup,"

A little copy/paste glitch..
code (on blog and on github) says 'text entry box' where a 
FontButton is used:


 writeln("The text entry box holds: ", fontButton.getFontName());

Yup, it was. I'm still trying to break the habit of putting 
optional stuff in angle brackets, '<' and '>,' which markdown 
doesn't like. Thanks for catching that.


 Thanks again for the Blog.


I'm delighted anybody's reading it. :)

Hmm... I'm not sure why the links didn't show up for you. I just 
double-checked and they're in the .md file and version of the 
file has been in place for at least 10 days.

Still, no harm in having them on this forum as well.

Thanks for taking an interest.

Not sure about .md or file version, but there are no links in the 
actual blog post:
http://gtkdcoding.com/2019/02/15/0010-checkbutton.html
and apparently also not in in this .md file:

This is actually the .md source file for the above html file, so

Thanks for catching yet another broken link.

Thanks for the new posts.

Link dead? It's also not listed on the blog post list. But I have 
read it some days before, and what I noticed is that you used the 
sources from ~/.dub/packages/gtk-d-...
I suspect you played with dub + gtkd by that time because I think 
they wouldn't be there otherwise. So if you use dmd in the 
example you might want to better use /usr/include/dmd/gtkd3/ 
(after installing gtkd).

I installed gtkd recently like shown here
https://github.com/gtkd-developers/GtkD/wiki
and here
https://d-apt.sourceforge.io/

which was basically this (-85 being my dmd version):

sudo wget 
https://netcologne.dl.sourceforge.net/project/d-apt/files/d-apt.list -O
/etc/apt/sources.list.d/d-apt.list
sudo apt-get update --allow-insecure-repositories && sudo apt-get 
-y --allow-unauthenticated install --reinstall d-apt-keyring && 
sudo apt-get update
sudo apt install libgtkd3-85 libgtkd3-dev libgtkd3-doc

and I compile like this:
dmd -de -w -m64 -I/usr/include/dmd/gtkd3/ -L-lgtkd-3 -run 
label_008_02_markup.d

Not sure if you need the -m64 on x64 linux with a dmd64, should 
be the default then and works without.

I'd suggest adding pictures! It's very easy to take a screen shot 
and not much harder to link them and they offer far more interest.

You're the second person to suggest this, so I'll explain my 
reasoning. I assure you, it's not because I'm lazy or don't know 
where the Print Screen button is. :)

My original plan was to include screenshots. Then I thought back 
over my own experiences with reading tutorial sites. I have a 
tendency to look at the screenshot, skim the article, 
copy-n-paste the code, and go off to do other things. I've also 
noticed this in others. It's often quite obvious someone hasn't 
read something carefully just by the questions they ask (present 
company excluded).

And I think images deter people from paying close attention while 
reading. I can't back this up with statistics or research other 
than my own, but I have noticed a decline in reading 
comprehension over the last 30 years as the Internet went from 
text-only to images and ads filling our screens.

So the bottom line is, by leaving out images, I feel I'm doing my 
bit for literacy. If there's nothing else besides text, it's all 
the reader has to engage with and I'm hoping this will engender a 
complete understanding of the subjects I cover... as much as is 
possible.

It's also why I keep the frills down to an absolute minimum. I've 
tossed thousands of words because they veered too far off topic 
or were written just to get a laugh or whatever.

And there you have it, the philosophy behind gtkDcoding.

Thanks for reading, Michelle. And keep the comments coming, 
please.

Oops! Forgot to say...

I get why you want images. You were asking about animation the 
other day, so obviously you're a visual artist. So am I and I 
know how drawn I am to imagery and I imagine most artists are.

Again, thanks for your feedback, Michelle.

then do a switch up to keep poor Timmy off balance. You can tune

As a side note, in 0004 you say:

 We can still call the constructor, even though strictly 
 speaking it’s private, because by using ‘new MyButton()’ the 
 constructor isn’t being called directly, but as part of a 
 lower-level process for instantiating the object.


I'm still new to D too, but I think it works in this scenario 
because private in D works on the module/file level. 
main/TestRigWindow/MyButton are defined in the same file (module) 
and thus can access each others private members. If you put the 
button class in its own file/module and import it then you would 
have to make its constructor public to access it.

By gar, you're right. I hadn't even looked into this because I 
assumed it was the same as PHP and C++.

Thanks for pointing this out.
