I have developed an app that uses a web view and I’m having problems to publish it in the Mac App Store as more people has reported in the past.
There’s an easy solution, using an OS X native web view (I’ll explain now how to do it), but that doesn’t work for me because I have developed the UI with OpenGL and when I use an NS-control (not only a web view, a button, search field…) it doesn’t appear. Is there a way to make it work over an OpenGL surface?
Also, I think I read in the past it’s possible to compile qtwebkit without HTML5 video support (that seems to be the problem with Apple rules because it uses a private API) but now I cannot find where I read it and I’m not sure if that would work. If somebody has tried it and could explain me how to do it I would appreciate it, because I have never compiled Qt or QtWebkit.
Now, for the people that want to use a native webview in OS X this is a how to:
1) Add this line in the .pro file to use Cocoa and Webkit:
LIBS += -framework Cocoa -framework WebKit
2) As we are going to use Objective-C it’s important that the classes that use Objective-C are in a .mm file instead of .cpp . The .pro file should look like this:
SOURCES += main.cpp
OBJECTIVE_SOURCES += cocoaclass.mm
HEADERS += cocoaclass.h
3) Our NS view will be wrapped in a QMacCocoaViewContainer derived class. We will use that class in the rest of our Qt code like if it was a QWidget. This is a sample class with a webview that opens Google when it’s created.
cocoawebview.h
#ifndef COCOAWEBVIEW_H
#define COCOAWEBVIEW_H
#include <QMacCocoaViewContainer>
class CocoaWebView : public QMacCocoaViewContainer
{
public:
CocoaWebView(QWidget *parent);
};
#endif // COCOAWEBVIEW_H
cocoawebview.mm
#include "cocoawebview.h"
#include <WebKit/WebKit.h>
#include <Webkit/WebView.h>
CocoaWebView::CocoaWebView(QWidget *parent) : QMacCocoaViewContainer(0,parent)
{
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
NSRect rect = {{0, 0},{parent->width(), parent->height()}};
WebView *webView = [[WebView alloc] initWithFrame:rect frameName:nil groupName:nil];
setCocoaView(webView);
[[static_cast<WebView *> (this->cocoaView()) mainFrame] loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:[NSString stringWithString:@"http://www.google.com"]]]];
[webView release];
[pool release];
}
PS: I’m using Qt 4.8.3
