Hi Ron. Your blog is great. I have saved it for the future. (I 
know it from reddit).
I would also like to request a future blog post about animation.
I know you have done that in the past, but i am thinking of some 
animation triggered by user input (say a button, or some text 
field, which provides parameters for a circle).

Okay. I'll see what I can come up with. Lead time is 2-3 months, 
just so you're aware.

Just to make sure I know exactly what you want...

- the user inputs parameters for a circle - I'm assuming size, 
position, perhaps the fraction of the circle (half, quarter, 
two-thirds, whatever)
- the user then clicks a button and that draws the circle.

Is that more or less what you're after?

Hi Ron!

Do you still have the Maurer Rose example? Do you think it could 
fit this kind of example?

I was referring to this example I made some time ago:

https://gitlab.com/amcorbi/dmaurerrose

I think this is somewhat related to what te OP was asking for.

Assuming you are on GNU/Linux, a simple 'dub run' is all you have 
to do to make it compile and run.

Yes, it uses 'sed' to get 'constants.d' from 'constants.d.in' at 
configuration time.

So you can write your own 'constants.d' with the appropiate 
values for UIDIR and DATADIR and delete/comment the the 
preBuildCommands in dub.sdl.

Hope this helps.

Yes something in that manner.
I am not familiar with GTK, i have done a few things in QT.
I am mainly interested in the information passing.
When i make some change to the input || hit enter || hit the 
button, the scene will change accordingly.

For a more satisfying example, you could have a ball on one line. 
Below that you have a horizontal slider. Whenever you move the 
slider, the ball on the line will move accordingly.

Would you be able to do a quick sketch/rough drawing of this? 
Perhaps before and after drawings? I wanna make sure I understand 
exactly what you're looking for. I don't know if this forum will 
allow images, so perhaps we could switch over to email 
(gtkdcoding gmail.com) so you can attach them.

Another useful tutorial would be something using bindProperty 
and/or bindPropertyWithClosures. Once I used bindProperty with 
vala, but I think there is no any example to do it with gtkd.

Yes that one. Let me define a use case. We have a button spawning 
a thread doing some time consuming job (we can use 
Thread.sleep(5.seconds)). I want this button disabled so that 
user cannot spawn another thread while the first one is on duty. 
In the same time, we show a spinner while job is running. After 
completion, we want to set button enabled and to make the spinner 
invisible. Instead of setting properties of button and spinner 
separately, we can bind disabled property of the button and 
visible property of the spinner each other. In vala, we can use 
something like (pseudo code):

"this" may refer to a self pointer to an instance of derived 
spinner class:

this.bind_property("customWorkingProperty", somebutton, 
"sensitive", BindingFlags.INVERT_BOOLEAN);

bool customWorkingProperty() will be responsible for showing and 
hiding the spinner.

This is actually the subject of an up-coming post which is 
scheduled to go live on Feb. 25, 2020. It uses setSensitive() 
rather than bindProperty(), but it has the same effect.

Yes, but what if you set sensitive properties of a bunch of the 
widgets in the same time. Each time you have to write and call 
setSensitive() for each widgets. If you bind their sensitivity 
property to one single widget, you can only switch one widget's 
property, and others will set automatically.

void doWhenDownloadIsComplete1(){// a lot of code pollution
     but1.setSensitive(false);
     but2.setSensitive(false);
     .
     .
     entry2.setSensitive(false);
}

...

void doWhenDownloadIsComplete2(){ // nicer
     but1.setSensitive(false);
     // other widgets' sensitive properties are binded to of but1. 
No extra code needed.
}

Actually I have just tried this with gtkd and working:

button1.bindProperty("sensitive", entry1, "sensitive", 
GBindingFlags.DEFAULT);
