[SOLVED} Problems with QWebView

Paawan

Hi All,

I have derived a class from QWidget. Named it WebBrowser.

I then included QWebView class in the WebBrowser class.

When I try to make a QWebView object I am getting all sorts of problems.

This is what I did like any other object:

In the WebBrowser header file:

QWebView * browser;

In the WebBrowser CPP file:

browser = new QWebView;

I am getting

webbrowser.obj:-1: error: LNK2019: unresolved external symbol "__declspec(dllimport) public: __cdecl QWebView::QWebView(class QWidget *)" (_imp??0QWebView@@QEAA@PEAVQWidget@@@Z) referenced in function "public: void __cdecl WebBrowser::loadPage(void)" (?loadPage@WebBrowser@@QEAAXXZ)

webbrowser.obj:-1: error: LNK2019: unresolved external symbol "__declspec(dllimport) public: virtual __cdecl QWebView::~QWebView(void)" (_imp??1QWebView@@UEAA@XZ) referenced in function "public: virtual void * __cdecl QWebView::`scalar deleting destructor'(unsigned int)" (??_GQWebView@@UEAAPEAXI@Z)

About 18 more errors like this.

Please help.

Thanks

Hi,

Did you add

@QT += webkit@

to your pro file ?

Hi,

I now added. But still get give error messages. First one below:

webbrowser.obj:-1: error: LNK2019: unresolved external symbol "__declspec(dllimport) public: __cdecl QWebView::QWebView(class QWidget *)" (_imp??0QWebView@@QEAA@PEAVQWidget@@@Z) referenced in function "public: void __cdecl WebBrowser::loadPage(void)" (?loadPage@WebBrowser@@QEAAXXZ)

webbrowser.obj:-1: error: LNK2019: unresolved external symbol "__declspec(dllimport) public: virtual __cdecl QWebView::~QWebView(void)" (_imp??1QWebView@@UEAA@XZ) referenced in function "public: virtual void * __cdecl QWebView::`scalar deleting destructor'(unsigned int)" (??_GQWebView@@UEAAPEAXI@Z)

Try to add

@QT += webkitwidgets@

to your pro file

I did try. It did not work.

How do I check if I have the webkit libraries in my installation?

SGaist

Then which version of Qt are you using on which OS and how did you install it ?

Paawan

Hi,

The OS is Windows 8 Pro

Qt Creator 2.7.0

Qt 5.0.2 (32 bit)

Have you tried to compile/run the demos\browser example?

Paawan

Hi,

When I try to compile the application without adding QT +=webkitwidgets, the applications does not compile.

When I later add QT +=webkitwidgets it still does not compile.

But when I make a new project and before compiling add QT +=webkitwidgets everything works fine.

Not sure why it does like that but I can make progress.

Thank you all for your time.

One more thing when you are adding @QT += webkitwidgets@ if there have already @QT+= deceleration@ then just add webkitwidgets after existing line. Do not replace existing line.
