Detailed Description

A variant of QIconView that honors KDE's system-wide settings.

This Widget extends the functionality of QIconView to honor the system wide settings for Single Click/Double Click mode, Auto Selection and Change Cursor over Link.

There is a new signal executed(). It gets connected to either QIconView::clicked() or QIconView::doubleClicked() depending on the KDE wide Single Click/Double Click settings. It is strongly recommended that you use this signal instead of the above mentioned. This way you don't need to care about the current settings. If you want to get informed when the user selects something connect to the QIconView::selectionChanged() signal.

Member Function Documentation

void K3IconView::cancelPendingHeldSignal ( )

protected

This method allows to handle correctly cases where a subclass needs the held() signal to not be triggered without calling a K3IconView::contentsDrag*Event() method (which have side effects because they forward to QIconView).

void K3IconView::doubleClicked ( Q3IconViewItem *  item, const QPoint &  pos  )

signal

This signal gets emitted whenever the user double clicks into the iconview.

Parameters

item	is the pointer to the clicked iconview item.
pos	is the position where the user has clicked, and

Note that you may not delete any QIconViewItem objects in slots connected to this signal.

This signal is more or less here for the sake of completeness. You should normally not need to use this. In most cases it's better to use executed() instead.

void K3IconView::executed ( Q3IconViewItem *  item )

signal

This signal is emitted whenever the user executes an iconview item.

That means depending on the KDE wide Single Click/Double Click setting the user clicked or double clicked on that item.

Parameters

item	is the pointer to the executed iconview item.

Note that you may not delete any QIconViewItem objects in slots connected to this signal.

void K3IconView::executed ( Q3IconViewItem *  item, const QPoint &  pos  )

signal

This signal is emitted whenever the user executes an iconview item.

That means depending on the KDE wide Single Click/Double Click setting the user clicked or double clicked on that item.

Parameters

item	is the pointer to the executed iconview item.
pos	is the position where the user has clicked

Note that you may not delete any QIconViewItem objects in slots connected to this signal.
