Detailed Description

pqExpandableTableView extends pqTableView to add support for the following features:

• Expand/Grow table: If the user edits past the last item the view will fire a signal (editPastLastRow()) enabling observer to add new row to the table.
• Skip non-editable items: When editing, in a QTableView one can hit tab to edit the next item. However, if the next item is not editable, the editing is stopped. pqExpandableTableView makes it possible to skip non-editable items and continue with the editing.

Constructor & Destructor Documentation

pqExpandableTableView()

pqExpandableTableView::pqExpandableTableView

(

QWidget *

parent = nullptr

)

~pqExpandableTableView()

pqExpandableTableView::~pqExpandableTableView ( )

override

Member Function Documentation

setPasteEnabled()

void pqExpandableTableView::setPasteEnabled

(

bool

enable

)

Enable pasting in table from clipboard.

Default is true.

editPastLastRow

void pqExpandableTableView::editPastLastRow ( )

signal

signal fired when the user edits past the last row.

Handlers can add a new row to the table, if needed, to allow used to edit expandable tables with ease.

moveCursor()

QModelIndex pqExpandableTableView::moveCursor ( CursorAction  cursorAction, Qt::KeyboardModifiers  modifiers  )

overrideprotected

Working together with logic in closeEditor().

This methods makes it possible to skip past non-editable items.

closeEditor()

void pqExpandableTableView::closeEditor ( QWidget *  editor, QAbstractItemDelegate::EndEditHint  hint  )

overrideprotected

Overridden to set MoveToNextEditableItem so that moveCursor() can skip non-editable items.

Also if moved past the last rows/last column, this will fire the editPastLastRow() signal.

keyPressEvent()

void pqExpandableTableView::keyPressEvent ( QKeyEvent *  event )

overrideprotected

Overridden to capture Ctrl-V for pasting table data into the table.
