Extending from GTKWidget

[lisoformio]

Hi all,

do you have example, links to examples of FreeBasic code about deriving/extending from GTKWidgets?

I only found these two examples, not in FreeBasic:

http://php-gtk.eu/it/code-snippets/exte ... ted-graphs

thanks!

Hi,

as it would happen I worked on a custom GTK widget recently, although not in FB, but it's easy enough to translate. So I've added the result to FB's examples directory:

customgtkwidget.bas
customgtkwidget.bi

Some links I've found helpful in this regard:

• Tutorial from XFCE with some actually useful explanations: http://xfc.xfce.org/docs/howto/html/custom_widgets.html
• Interesting details from the GTK+ docs, for example: https://developer.gnome.org/gtk3/stable ... model.html
• https://developer.gnome.org/gtk-tutoria ... c2180.html
• https://developer.gnome.org/gtkmm-tutor ... ts.html.en

OK! That's what I didn't find in my quest :) Thank you very much.

In the last two day I used the gtk.bi to understand how to manage extending from gtkwidget.

In customwidget.bi I find:

declare function mycustomwidget_get_type() as GType
declare function mycustomwidget_new() as GtkWidget ptr

In customwidget.bas I find:

function mycustomwidget_new() as GtkWidget ptr
return GTK_WIDGET(g_object_new(mycustomwidget_get_type(), NULL))
end function

but no code for

mycustomwidget_get_type()

Am I in misunderstanding?

Looks like it is declared by the G_DEFINE_TYPE() macro.

Code: Select all

G_DEFINE_TYPE(MyCustomWidget, mycustomwidget, GTK_TYPE_WIDGET)

OK!
