Bayan da farko post Na karanta wani tsokaci cewa zai fi kyau in fara da wani abu mai rikitarwa fiye da "hello world", to zan yi jerin abubuwa (3 na 4) post don ƙirƙirar aikace-aikace mai sauƙi (tare da vala + gtk 3).

Aikace-aikacen zai kunshi zabi mai yawa na zabi da amsar tambaya (Nau'in Trivia), wanda amsar tambayoyin 3 ba daidai ba ya kare (wasa sama da kasa), kuma makasudin shine amsar tambayoyi da yawa kamar yadda zai yiwu, ga kowace tambaya da kuke da iyakance lokacin amsawa

Zane

Babban zane na aikace-aikacenmu zai kasance:

Daga baya zamu sanya wasu maballin da zasu bamu damar 50% (kawar da amsoshi guda biyu marasa kyau), daskare lokaci, wuce tambaya. Duk ana iya amfani da su sau ɗaya kawai, ana tawaya lokacin da ake amfani da su.

Zayyana a Code
Kamar yadda zamu iya gani a cikin zane zamu iya ganin abubuwan gtk wadanda zamuyi amfani dasu:

Amsoshi -> Button.

Tambaya -> Alamar alama.

Lokaci -> Ci gabaBar.

Abubuwa mara daidai / daidai da Tambayoyi -> Lakabi.

Zamu iya ganin cewa muna da tsari na tsaye saboda haka zamu iya amfani da GBox a tsaye.

Code

int main (kirtani [] args) {Gtk.init (ref args); var taga = sabon Gtk.Window (); window.title = "aikace-aikace"; window.window_position = Gtk.WindowPosition.CENTER; taga.set_default_size (300, 340); window.destroy.connect (Gtk.main_quit); taga.set_border_width (10); // akwatin tsaye var akwatin = sabon Gtk.Box (Gtk.Orientation.VERTICAL, 0); akwatin.set_spacing (10); // Lakabi don tambaya var tambaya = sabon Gtk.Label ("Tambaya?"); // lokacin shirin bar var time_bar = sabon Gtk.ProgressBar (); timebar.set_text ("Lokaci"); time_bar.set_show_text (gaskiya ne); // Maballin amsawa var response1 = sabon Gtk.Button.with_label ("Amsa 1"); var resposta2 = sabon Gtk.Button.with_label ("Amsa 2"); var resposta3 = sabon Gtk.Button.with_label ("Amsa 3"); var resposta4 = sabon Gtk.Button.with_label ("Amsa 4"); // alamun bayanai var maki = sabon Gtk.Label ("Points: 0"); akwatin.pack_start (tambaya); akwatin.pack_start (lokaci_bar); akwatin.pack_start (amsa1); akwatin.pack_start (resposta2); akwatin.pack_start (resposta3); akwatin.pack_start (resposta4); akwatin.pack_start (maki); taga.add (akwati); taga.kashe duka (); Gtk.main (); dawowa 0;}

Don motsa "lokaci" muna amfani da GLib.Timeout inda kowane milliseconds 500 za a kunna shi (madauki ne inda canjin da ke dauke da darajar sandar mu zai karu)

GLib.Timeout.add (500, () => {// Samu ci gaban na yanzu: // (0.0 -> 0%; 1.0 -> 100%) ci gaba biyu = time_bar.get_fraction (); // Sabunta sandar: ci gaba = ci gaba + 0.01; time_bar.set_fraction (ci gaba); // Maimaita har sai 100% dawo da ci gaba <1.0;});
