guru

Hi,
I want to create a shortcut for spacebar key in my qtapplication, I tried following code,

@QShortcut *VKey_SpaceBar = new QShortcut (QKeySequence (tr("space")), ui->chkAll );

 QObject :: connect (VKey_SpaceBar, SIGNAL(activated()), ui->chkAll, SLOT(click()));@

But, nothing happen, whats wrong in my code.

Try simply:

@QShortcut spacebarShortdcur(QKeySequence(Qt::Key_Space), this, SLOT(calcDirectorySize()), 0, Qt::WidgetWithChildrenShortcut);@
