Gtkada widget from scratch
I donβt have a lot of hope for this but anyway.
I need to create a widget to select a range (like a scale widget but with two cursors, one for the lower bound and another for the upper bound). This needs to be built "from scratch". According to the Gtkada documentation, I just have to take a look at the gtkdial example (gtkdial seems to be the classic example for gtk to build widget from scratch).
The example is clearly out of date, a lot of functions, packages and events donβt exist anymore.
For example Gtk.Widget.Realize_Handling is gone (instead we have on_Realize I think), the function Get_Count doesnβt exist as the event "size_request"β¦ I tried to do it on my own by reading and understanding the source code, but IβΒ m still a beginner with GTK.
Do you know if an up-to-date version of this example exists?
