QTabWidget does not accept QHelpEngine's central widget

[dalishi]

Hi I'm following this link to embed help file into my app. The QTabWidget::addTab does not accept the QHelpContentWidget * helpEngine->contentWidget() and QHelpIndexWidget *.

QTabWidget* tWidget = new QTabWidget;
tWidget->setMaximumWidth(200);
tWidget->addTab(helpEngine->contentWidget(), "Contents");
tWidget->addTab(helpEngine->indexWidget(), "Index");

 error: no matching function for call to ‘QTabWidget::addTab(QHelpIndexWidget*, const char [6])’
     tabWidget->addTab(helpEngine->indexWidget(), "Index");
                                                             ^

Hi,

Are you missing the include for QHelpContentWidget ?

@SGaist Thanks. And I was being fool to forget this. A little surprised though that the <QHelpEngine> does not include <QHelpContentWidget> and <QHelpIndexWidget>.

There's no reason for that, the engine can be used without these two widget classes.

Hi @SGaist Thanks for the reply. Now I get the QHelpEngine worked in my application with a .qch and .qhc.
However, when I try to statically link my application to Qt (which i build myself), using

~/qt5-static-build/qtbase/bin/qmake -config release ..

there's an error:

Project ERROR: Unknown module(s) in QT: help

I found the libQt5Help.a is under /qttools/lib/ while other main modules like libQt5Gui are in /qtbase/lib/.
Do I need to specially indicate where to find the library? I have Qt += help in my .pro file.

Looks like it didn't get installed. You can call make install in the module build folder and see if it fixes that.
