Hi all,
This is my first post in the list...
I'm a devuan nonofficial developer (and gnuinos), and i'm
building some applications in gtkmm. One of them is a graphical
interface for simple-netaid, developed by Edward Bartolo. Here
you are a demo:
www.gnuinos.org/simple-netaid-gtk3/snetaid
As you can see, there is a first application scanning the
available active wifis. This is a multithread proccess against
blocking the spinner.
Well..., i'm trying to apply some custom widgets to the project.
I had a look at the following example in the Gnome Developer's
website:
https://developer.gnome.org/gtkmm-tutorial/stable/sec-custom-widgets.html.en
and tried to simplify the example to the case of a custom widget
containing only a button. Here you are the code:
wget https://gnuinos.org/custom-widget.tar.bz2
The question is that if i set to *true* the method:
set_has_window(false);
in the CustomWidget class, then the button is not shown. On the
other hand, if i set it to *false*, i get the following bug:
(customwidget:18925): Gtk-CRITICAL **: gtk_box_pack: assertion
'gtk_widget_get_parent (child) == NULL' failed
**
Gtk:ERROR:/build/gtk+3.0-b165l9/gtk+3.0-3.14.5/./gtk/gtkwidget.c:12230:gtk_widget_real_realize:
assertion failed: (!gtk_widget_get_has_window (widget))
Aborted
Any hints?
Thanks in advance,
Aitor.
I need to add the following functions:
virtual Gtk::SizeRequestMode get_request_mode_vfunc() const;
virtual void get_preferred_width_vfunc(int& minimum_width,
int& natural_width) const;
virtual void get_preferred_height_for_width_vfunc(int width,
int& minimum_height, int& natural_height) const;
virtual void get_preferred_height_vfunc(int& minimum_height,
int& natural_height) const;
virtual void get_preferred_width_for_height_vfunc(int height,
int& minimum_width, int& natural_width) const;
virtual void on_size_allocate(Gtk::Allocation& allocation);
virtual void on_map();
virtual void on_unmap();
virtual void on_realize();
virtual void on_unrealize();
Trying again :)
Cheers,
Aitor.
