WebKitGTK WebView Gadget
Verfasst: 19.01.2011 23:15
Das Projekt wird in http://forums.purebasic.com/german/view ... =8&t=23313 fortgeführt.
Da ja unter Linux x64 das WebGadget nicht verfügbar ist, habe ich mal angefangen, ein Interface für das WebKitGTK zu schreiben. Genauer für den WebView-Teil davon. Aus dem WebKit werden nur die nötigen Funktionen importiert. Das ganze ist an OOP angelehnt.
System: Ubuntu 10.10 x64, benötigtes/getestetes Package: libwebkit-1.0-2
Unter x86 nicht getestet, sollte aber auch funktionieren, sofern die Bibliothek installiert und der Pfad richtig gesetzt ist: AWPB_InitWebKit("/usr/lib/libwebkit-1.0.so.2") Rückgabe ist #True bei Erfolg, sonst #False.
Das WebView-Gadget wird in einem Container-Gadget erzeugt. Dieses wird automatisch angelegt. Die übergebene GadgetID gehört zu diesem Container. Die Events der WebView können nicht mit den PureBasic-Befehlen abgefangen werden, dafür sind die Callbacks nötig. Scrollbalken werden automatisch hinzugefügt, falls nötig.
