Hi There,

I honestly doubt that I'm in the right group here for this question
but i couldn't find another more appropriate group - if some one could
direct me.

I got a little UI going with a QTabWidget on it. On the bottom I have
two buttons, "<< perevious" and "next>>" with which i wanna let the
user "scroll" through the tabs. Now i got problems on how to modify
the currentIndex property of the tab widget that selects which tab is
currenly being displayed.
I've tried following:
void HelloForm::NextTab(void){
if (widget.tabWidget->currentIndex()!=-1)
{
widget.tabWidget->currentIndex(TabIndex=+1);
}
}
But I'm getting: "HelloForm.cpp:62: error: no matching function for
call to ‘QTabWidget::currentIndex(int&)’
/usr/include/qt4/QtGui/qtabwidget.h:106: note: candidates are: int
QTabWidget::currentIndex() const"

Any help would be appreciated!

Thank you!

Okay, got this going by using setCurrentIndex() instead but now i'm
getting something like "IBusInputContext::createInputContext: no
connection to ibus-daemon" - that i don't understand, seems like i
need to define some kind of connection...? :o Anyone a clue what that
stands for?

Trolltech offered (and I guess now nokia offers) Qt's mailing lists through a NNTP interface,
which I can't say enough good things about. Truly remarkable stuff. Please take a look at:

You are trying to call a method, currentIndex(int&), which was never defined. QTabWidget only has
int currentIndex() const. Maybe you intended to use QTabWidget::setCurrentIndex().

You can take a look at:

Hope this helps,

See the "newbie" forum on http://www.qtcentre.org/content/
I can also highly recommend the book "C++ GUI programming with QT4" - it's
worth every cent.
