Member Function Documentation
|
a pure virtual function to get a QWidget, that can be added to other widgets. This function is needed to make it possible for derived classes to derive from other widgets. Implements KFileView. Definition at line 55 of file kfilepreview.h. |
|
pure virtual function, that should be implemented to clear the view. At this moment the list is already empty Implements KFileView. Definition at line 139 of file kfilepreview.cpp. References KFileView::clearView(). |
|
Delets the current view and sets the view to the given The view is reparented to have this as parent, if necessary. Definition at line 78 of file kfilepreview.cpp. References QWidget::reparent(), KFileView::setParentView(), KFileView::setSorting(), KFileView::signaler(), KFileView::sorting(), and KFileView::widget(). |
|
Definition at line 67 of file kfilepreview.h. |
|
does a repaint of the view. The default implementation calls widget()->repaint(f) Reimplemented from KFileView. Definition at line 145 of file kfilepreview.cpp. References QWidget::repaint(), and KFileView::updateView(). |
|
Removes an item from the list; has to be implemented by the view. Call KFileView::removeItem( item ) after removing it. Reimplemented from KFileView. Definition at line 157 of file kfilepreview.cpp. References KFileView::isSelected(), and KFileView::removeItem(). |
|
This hook is called when all items of the currently listed directory are listed and inserted into the view, i.e. there won't come any new items anymore. Reimplemented from KFileView. Definition at line 166 of file kfilepreview.cpp. References KFileView::listingCompleted(). |
|
Tells the view that it should highlight the item. This function must be implemented by the view. Implements KFileView. Definition at line 202 of file kfilepreview.cpp. References KFileView::setSelected(). |
|
Implements KFileView. Definition at line 193 of file kfilepreview.cpp. References KFileView::isSelected(). |
|
Clears any selection, unhighlights everything. Must be implemented by the view. Implements KFileView. Definition at line 177 of file kfilepreview.cpp. References KFileView::clearSelection(). |
|
Selects all items. You may want to override this, if you can implement it more efficiently than calling setSelected() with every item. This works only in Multiselection mode of course. Reimplemented from KFileView. Definition at line 183 of file kfilepreview.cpp. References KFileView::selectAll(). |
|
Inverts the current selection, i.e. selects all items, that were up to now not selected and deselects the other. Reimplemented from KFileView. Definition at line 188 of file kfilepreview.cpp. References KFileView::invertSelection(). |
|
The derived view must implement this function to add the file in the widget. Make sure to call this implementation, i.e. KFileView::insertItem( i ); Reimplemented from KFileView. Definition at line 127 of file kfilepreview.cpp. References KFileView::insertItem(). |
|
Clears the view and all item lists.
Reimplemented from KFileView. Definition at line 171 of file kfilepreview.cpp. References KFileView::clear(). |
|
Reimplement this to set the item having focus. Implements KFileView. Definition at line 206 of file kfilepreview.cpp. References KFileView::setCurrentItem(). |
|
Implements KFileView. Definition at line 211 of file kfilepreview.cpp. References KFileView::currentFileItem(). |
|
Sets the sorting order of the view. Default is QDir::Name | QDir::IgnoreCase | QDir::DirsFirst Override this in your subclass and sort accordingly (usually by setting the sorting-key for every item and telling QIconView or QListView to sort. A view may choose to use a different sorting than QDir::Name, Time or Size. E.g. to sort by mimetype or any possible string. Set the sorting to QDir::Unsorted for that and do the rest internally.
Reimplemented from KFileView. Definition at line 133 of file kfilepreview.cpp. References KFileView::setSorting(), and KFileView::sorting(). |
|
This overrides KFileView::actionCollection() by returning the actionCollection() of the KFileView (member left) it contains. This means that KFilePreview will never create a KActionCollection object of its own. Reimplemented from KFileView. Definition at line 254 of file kfilepreview.cpp. References KFileView::actionCollection(). |
|
pure virtual function, that should be implemented to make item i visible, i.e. by scrolling the view appropriately. Implements KFileView. Definition at line 234 of file kfilepreview.cpp. References KFileView::ensureItemVisible(). |
