moved User:Humitos/PortingFinance to Features/GTK3/Porting/Finance: To be available / editable for any user
This page is being performed while I'm porting Finance Activity to Gtk3.
There is a [http://bugs.sugarlabs.org/ticket/3740 ticket] with some useful information that I'm using on the porting and to keep tracking this port. Besides, this wiki page will be useful to write some code snippets about what are the difficulties that I'm having on the port and maybe can be useful for someone else.
I will take [[User:Humitos/PortingGetBooks|this guide]] as reference on the Gtk3 porting.
= Gtk.EventBox =
EventBox has not <tt>get_colormap</tt> method anymore and this method is used to set the background color. Now, instead of this one I'm using <tt>Gdk.Color.parse</tt> to parse the color string:
ebox = gtk.EventBox()
ebox.modify_bg(gtk.STATE_NORMAL, ebox.get_colormap().alloc_color('#000000'))
replaced by:
replaced by:
ebox = Gtk.EventBox()
parse, color = Gdk.Color.parse('#000000')
parse, color = Gdk.Color.parse('#000000')
self.helpbox.modify_bg(Gtk.StateType.NORMAL, color)
self.helpbox.modify_bg(Gtk.StateType.NORMAL, color)
= Gtk.TreeViewColumn =
The callback function used by <tt>Gtk.TreeViewColumn.set_cell_data_func</tt> receives a new argument called: ''data''
col = Gtk.TreeViewColumn(_('Description'), renderer)
col.set_cell_data_func(renderer, self.description_render_cb)
added a new argument to the function definition:
def description_render_cb(self, column, cell_renderer, model, iter, data):
