I want to apply a certain behaviour to a label. When a lateral button is clicked, the corresponding label should rotate 90 degrees. It can be easily done in vala, but I can't discover the particular syntax on genie. The vala code I am trying to reproduce comes from elementary OS getting started guide : hello_button.clicked.connect(() => { hello_label.label = "Hello World!"; hello_button.sensitive = false; }); rotate_button.clicked.connect(() => { rotate_label.angle = 90; rotate_label.label = "Verbal"; rotate_button.sensitive = false; }); I actually managed to reproduce almost entirely the code

Background My aim is to improve a little text editor as an exercise. It is running fine after the HeaderBar was added, however I can't find a way to pack buttons in it. Code uses Granite.Widgets Gtk init Gtk.init (ref args) var app = new Application () app.show_all () Gtk.main () // This class holds all the elements from the GUI class Application : Gtk.Window _view:Gtk.TextView construct () // Prepare Gtk.Window: this.window_position = Gtk.WindowPosition.CENTER this.destroy.connect (Gtk.main_quit) this.set_default_size (400, 400) // Headerbar definition headerbar:Gtk.HeaderBar = new Gtk

the code from: Genie howto repeat a string N times as an string array Genie howto repeat a string N times as an string array def repeatwithsep (e: string, n: int, separator: string): string var elen = e.length; var slen = separator.length; var a = new StringBuilder.sized ((elen * n) + (slen * (n - 1)) + 1); for var i = 0 to (n - 1) if i != 0 a.append_len (separator, slen) a.append_len (e, elen) return (owned) a.str var a is a local variable, when a goes out of scope, it will be destroyed. why this function return (owned) a.str what is the difference between return a.str return (owned) a.str

From Linux, I'm using Meson (0.44.0) within Gnome Builder (3.26.4) for a console program that will use Gee and GXml. My intent is to write this in Genie. When I use Meson within Gnome Builder it fails but the same succeeds when invoked from the command line using valac (0.38.8) as follows: valac --pkg=gtk+-3.0 --pkg=gee-0.8 --pkg=gxml-0.16 main.gs There is no error from the above. I've tried setting up meson.build with gee and gxml as dependency and alternatively as vala_args . Same error. Checking pkg-config, I get the following: $ pkg-config --libs gxml-0.16 -L/usr/local/lib64 -lgxml-0.16

The Vala Tutorial has an example about DBus using anonymous methods . Bus.own_name (BusType.SESSION, "org.example.DemoService", /* name to register */ BusNameOwnerFlags.NONE, /* flags */ on_bus_aquired, /* callback function on registration succeeded */ () => {}, /* callback on name register succeeded */ () => stderr.printf ("Could not acquire name\n")); /* callback on name lost */ I am trying to rewrite this code in Genie, but could not manage to convert the two last lines. The Genie Tutorial only has an example on how to use a closure to define an event handler . f.my_event += def (t, a)

Below is a working code of a ToolbarButton in Genie. The objective is to get the uri for the chosen file and return it back to the construct/init of the class. The problem is that in all examples I’ve come across global _variables are used (as shown in the code below). It looks unintuitive and I fear that whenever the code gets larger, it will become more difficult to remove bugs, since these variables will start to accumulate. Is any other way of making the function openfile return the uri to a regular variable within the construct/init of the class? Here is the code: uses Granite.Widgets Gtk
