QWebView doesn't load any external resources if it loads a html-file from qresources

由 Deadly 提交于 2019-12-23 09:41:01
问题 As described in the title my problem is that qwebview doesn't load a html file correctly if it resides in my resources.

My problem is that

Qt 4.6 Adding objects and sub-objects to QWebView window object (C++ & Javascript)

由 倾然丶 夕夏残阳落幕 提交于 2019-12-22 05:25:09
问题 I am working with Qt's QWebView, and have been finding lots of great uses for adding to the webkit window object. One thing I would like to do is nested objects... for instance: in Javascript I can... var api = new Object; api.os = new Object; api.os.foo = function(){} api.window = new Object(); api.window.bar = function(){} obviously in most cases this would be done through a more OO js-framework. This results in a tidy structure of: >>>api ---------------------------------------------------
