|
|
* 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
|
|
* QListWidget::itemClicked() or QListWidget::itemDoubleClicked()
|
|
* 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 QListWidget::itemSelectionChanged() signal.
