Ukwenza iVala + Gtk3 app. [Inxalenye yokuqala]

Emva kokuba iposi yokuqala Ndifunde amagqabantshintshi ukuba kungangcono ndiqale ngento entsonkothileyo kunokuba "molo kwihlabathi", emva koko ndiza kwenza ulandelelwano (3 o 4) Iposi yenza usetyenziso olulula (kunye nevala + gtk 3).

Isicelo siza kubandakanya umbuzo olula wokukhetha kunye nomdlalo wokuphendula (uhlobo lweTrivia), apho uphendula imibuzo emi-3 engalunganga (umdlalo ongaphezulu), kwaye injongo kukuphendula imibuzo emininzi kangangoko, kumbuzo ngamnye onawo Ixesha elilinganiselweyo lokuphendula.

Uyilo

Uyilo oluphambili lwesicelo sethu luya kuba:

Emva kwexesha siza kufaka amaqhosha aya kuthi asinike ithuba lokukhetha i-50% (isusa iimpendulo ezimbini ezingalunganga), ixesha lokumisa ixesha, uphumelele umbuzo. Zonke zinokusetyenziswa kube kanye, ukukhubazeka kube kanye kusetyenzisiwe.

Uyilo Ikhowudi
Njengoko sibona kuyilo sinokubona izinto ze-gtk esiza kuzisebenzisa:

Iimpendulo -> Iqhosha.

Umbuzo-> Ilebheli.

Ixesha -> InkqubelaBar.

Amanqaku achanekileyo / achanekileyo kunye nemibuzo-> Ilebheli.

Siyabona ukuba sinesakhiwo esime nkqo ngoko ke sinokusebenzisa i-GBox ngokuthe nkqo.

Ikhowudi

int engundoqo (umtya [] args) {Gtk.init (ref args); var iwindow = iGtk entsha.Window (); window.title = "usetyenziso"; window.window_position = Gtk.WindowPosition.CENTER; iwindow.set_default_size (300, 340); iwindow.destroy.connect (Gtk.main_quit); iwindow.set_border_width (10); // ibhokisi ethe nkqo var box = Gtk.Box entsha (Gtk.Orientation.VERTICAL, 0); ibhokisi.set_spacing (10); // Ilebheli yombuzo var umbuzo = iGtk.Label entsha ("Umbuzo?"); // ixesha lokucwangciswa kwebha yebar yexesha_bar = i-Gtk entsha. ixesha_bar.set_text ("Ixesha"); ixesha_bar.set_show_text (yinyani); // Amaqhosha okuphendula var impendulo1 = iGtk entsha.Iqhosha.with_label ("Impendulo 1"); var resposta2 = Gtk.Button.with_label entsha ("Phendula 2"); var resposta3 = Gtk.Button.with_label entsha ("Phendula u-3"); var resposta4 = Gtk.Button.with_label entsha ("Phendula u-4"); // iilebhile info var points = Gtk.Label entsha ("Amanqaku: 0"); ibhokisi.pack_start (umbuzo); ibhokisi.pack_start (ixesha_bar); ibhokisi.pack_start (impendulo1); ibhokisi.pack_start (resposta2); ibhokisi.pack_start (resposta3); ibhokisi.pack_start (resposta4); ibhokisi.pack_start (amanqaku); iwindow.add (ibhokisi); iwindow.show_all (); IGtk.main (); buyela 0;}

Ukuhambisa "ixesha" sisebenzisa i-GLib.Ukuvala ixesha apho yonke imizuzwana engama-500 iyakwenziwa ukuba isebenze (iluphu apho umahluko oqulathe ixabiso lebha yethu uya kunyuka)

GLib.Timeout.add (500, () => {// Fumana inkqubela phambili yangoku: // (0.0 -> 0%; 1.0 -> 100%) inkqubela phambili = time_bar.get_fraction (); // Hlaziya ibha: inkqubela = inkqubela phambili + 0.01; ixesha_bar.set_fraction (inkqubela phambili);
