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).

Glad you like it.

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?

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 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.

I had to look this up. I'd never heard of it before. That being said...

> Do you think it could fit this kind of example?

When I say "demo" I'm talking about examples of how to do various GTK GUI stuff rather than mathematical exercises. Trying to do this mathematical/drawing exercise, I'd be waaaaaaay out of my element. The few simple math/draw examples I did in Cairo (posts #0057 to #0064) is about my limit as far as math goes.

However, I can point you at this repository of Java examples: https://github.com/iabin/Maurer-Rose/tree/master/src

Using the methods outlined in the posts I've listed, you should be able to port it over from Java to D. I'm not a mathematician, so I wouldn't be of much help.

I wish you the best of luck on this endeavour.

I found a bindProperty() function in gobject/ObjectG.d. Is this what you're referring to?

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.
