问题 Is there any way to display a QImage (in memory, not on filesystem) in a QWebFrame without writing the image out to a temporary file? 回答1: One option might be using the data URI scheme. You basically base64 encode your picture and write the complete data into the URL. For example: data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAABAAAAAQAQMAAAAlPW0iAAAABlBMVEUAAAD///+l2Z/dAAAAM0lEQVR4nGP4/5/h/1+G/58ZDrAz3D/McH8yw83NDDeNGe4Ug9C9zwz3gVLMDA/A6P9/AFGGFyjOXZtQAAAAAElFTkSuQmCC WebKit should support

问题 I posted the question below, trying to use the QDomDocument classes. I was advised to use the QWebkit instead, but I'm very confused how to do what I need to do with QWebkit. I've never used it before so I'm rather unsure with it. Could anyone please offer any advice? Thanks! For the record, the function is using a QByteArray that when translated to text is a standard HTML file. ORIGINAL QUESTION: I have several divs in an HTML file with different classes, like this: <div class='A'>...</div>

问题 Now this code works with the slot mechanism. However, I want to try out the signal way also. However, I am unable to do so? Any more ideas on it? I want to call function f1 of the Javascript from the QT. However, I am unable to do so. I don't see the callback being received by the JS f1(). I have followed the earlier post on it, Qt QWEBview JavaScript callback . However, I am unable to do so. Here is my code. #include <QtGui/QApplication> #include <QApplication> #include <QDebug> #include

问题 The code below works fine except one thing, it does not follow the sign-up link. However if I go to my actual browser and in console type: document.getElementById("link-signup").click() It will redirect me to the desired page.

问题 I'm trying to use QWebView to implement a blog post editor. And I have some sample html snippets to insert into the editor by triggering menu actions. However, it's not convenient as QTextEdit to insert html. As for why I don't use QTextEdit , see my test code following: QTextEdit *edit = new QTextEdit; edit->insertHtml(tr("<div class=\"gci-hello\">Hello</div>")); qDebug() << edit->toHtml(); // --> the div tag disappeared So, if I use QWebView, the div tag will be reserved. But I can't find

问题 I want to use QWebPage in a non-GUI Qt application. By that, I mean that I don't want to communicate with the window server at all. Using QtGui is not a problem, though. QWebPage internally creates some QWidget instances. Thus, using QCoreApplication is not possible. When creating a QApplication instance though, I already immediately get a MacOSX dock icon. And I don't want that. It also means that it somehow registers itself in Cocoa as a GUI application. My question is not Mac-only. I would
