I want to write a small program with gtkd. I need to use Signals.connectData to transfer an int type parameter to the callback function. I don't know how to write it. I hope someone can help me. It would be best if you can provide a sample code. Thank!
It should be as easy as passing a pointer to your int value as data. You just need to cast it to void* as that is what is expected. More details here: https://api.gtkd.org/gobject.Signals.Signals.connectData.html
Btw, from https://docs.gtk.org/gobject/func.signal_connect_data.html :
This function is not directly available to language bindings.
I suppose GtkD guys forced generation of this method. Looks like bindings should not have it.
