Detailed Description

This is an implementation of AbstractRowController that aligns a gantt view with a QTreeView.

Definition at line 26 of file kgantttreeviewrowcontroller.h.

Member Function Documentation

int TreeViewRowController::headerHeight ( ) const
overridevirtual
Returns
The height of the header part of the view.

Implement this to control how much space is reserved at the top of the view for a header

Implements KGantt::AbstractRowController.

Definition at line 37 of file kgantttreeviewrowcontroller.cpp.

QModelIndex TreeViewRowController::indexAbove ( const QModelIndex idx) const
overridevirtual
Returns
The modelindex for the previous row before idx.
See also
QTreeView::indexAbove

Implements KGantt::AbstractRowController.

Definition at line 96 of file kgantttreeviewrowcontroller.cpp.

QModelIndex TreeViewRowController::indexBelow ( const QModelIndex idx) const
overridevirtual
Returns
The modelindex for the next row after idx.
See also
QTreeView::indexBelow

Implements KGantt::AbstractRowController.

Definition at line 102 of file kgantttreeviewrowcontroller.cpp.

bool TreeViewRowController::isRowVisible ( const QModelIndex idx) const
overridevirtual
Returns
true if the row containing index idx is visible in the view.

Implement this to allow KGantt to optimize how items on screen are created. It is not harmful to always return true here, but the View will not perform optimally.

Implements KGantt::AbstractRowController.

Definition at line 53 of file kgantttreeviewrowcontroller.cpp.

Span TreeViewRowController::rowGeometry ( const QModelIndex idx) const
overridevirtual
Returns
A Span consisting of the row offset and height for the row containing idx. A simple implementation might look like
Span MyRowCtrlr::rowGeometry(const QModelIndex& idx)
{
return Span(idx.row()*10,10);
}

Implements KGantt::AbstractRowController.

Definition at line 68 of file kgantttreeviewrowcontroller.cpp.

int TreeViewRowController::totalHeight ( ) const
overridevirtual
Returns
the total height of the rows. For uniformly sized rows that would be number_of_rows*row_height.

Implements KGantt::AbstractRowController.

Definition at line 48 of file kgantttreeviewrowcontroller.cpp.
