- * General implementation notes
- * ----------------------------
- *
- * In Qt4.3 the QColumnView widget has a default behavior regarding the
- * active column and the selection handling, which leads to some usability
- * problems within Dolphin:
- *
- * - No matter which mouse button has been clicked: If the mouse is above
- * a folder, the folder content will be loaded in the next column. The problem
- * is that this column also will marked as 'active column' within QColumnView,
- * hence it is not possible to select more than one folder within a column.
- *
- * - The currently opened folder is not always marked in the left column when
- * doing drag & drop and selections inside other columns.
- *
- * - The currently active column is visually not recognizable.
- *
- * - It is not possible for derived classes to remove inactive columns.
- *
- * DolphinView tries to bypass those points, but this required some workarounds:
- *
- * - QColumnView internally maps the selection model from the ColumnView to the
- * active column. As the active column from the Dolphin perspective is different
- * as the active column from QColumnView, the selection model is adjusted on
- * each interaction by the methods QColumnWidget::obtainSelectionModel(),
- * QColumnWidget::releaseSelectionModel() and QColumnView::requestSelectionModel().
- * QColumnView offers no hook to adjust this behavior, so those methods have to
- * be invoked throughout the code...
- *
- * - Some copy/paste code from QColumnView is part of DolphinColumnView::createColumn(), but Qt 4.4
- * will offer a solution for this.
- *
- * - The mousePressEvent() has been customized to prevent that folders are loaded on each
- * mouse click.
- *
- * We'll try to give some input for Trolltech if the Dolphin solution is stable enough, so hopefully
- * some workarounds can be removed when switching to Qt 4.4 or later.
