Detailed Description
Abstract baseclass for grids. A grid is used to convert between QModelIndex'es and gantt chart values (qreals) and to paint the background and header of the view.

Constructor & Destructor Documentation
◆ AbstractGrid()
AbstractGrid::AbstractGrid | ( | QObject * | parent = nullptr | ) |
Constructor. Creates an AbstractGrid with parent parent. The QObject parent is not used for anything internally.
Definition at line 17 of file kganttabstractgrid.cpp.
◆ ~AbstractGrid()
|
override |
Destructor. Does nothing
Definition at line 23 of file kganttabstractgrid.cpp.
Member Function Documentation
◆ drawBackground()
- Todo
- document this function
Reimplemented in KGantt::DateTimeGrid.
Definition at line 73 of file kganttabstractgrid.cpp.
◆ drawForeground()
- Todo
- document this function
Reimplemented in KGantt::DateTimeGrid.
Definition at line 79 of file kganttabstractgrid.cpp.
◆ isSatisfiedConstraint()
bool AbstractGrid::isSatisfiedConstraint | ( | const Constraint & | c | ) | const |
- Returns
- true if the startpoint is before the endpoint of the constraint c.
Definition at line 50 of file kganttabstractgrid.cpp.
◆ mapFromChart() [1/2]
|
pure virtual |
Implement this to update the model data based on the location of the item. Check against the constraints list to make sure no hard constraints are violated by writing back to the model.
- Returns
- true if the update succeeded.
Implemented in KGantt::DateTimeGrid.
◆ mapFromChart() [2/2]
|
virtual |
Implement this to map from x to the corresponding location in the view. Return an invalid value if x cannot be mapped.
Reimplemented in KGantt::DateTimeGrid.
Definition at line 67 of file kganttabstractgrid.cpp.
◆ mapToChart() [1/2]
|
pure virtual |
Implement this to map from the data in the model to the location of the corresponding item in the view.
Implemented in KGantt::DateTimeGrid.
◆ mapToChart() [2/2]
|
virtual |
Implement this to map from value to the corresponding location in the view. Return a negative value if value cannot be mapped. The default implementation returns -1.0.
Reimplemented in KGantt::DateTimeGrid.
Definition at line 61 of file kganttabstractgrid.cpp.
◆ model()
QAbstractItemModel * AbstractGrid::model | ( | ) | const |
- Returns
- The QAbstractItemModel used by this grid
Definition at line 35 of file kganttabstractgrid.cpp.
◆ paintGrid()
|
pure virtual |
Implement this to paint the background of the view – typically with some grid lines.
- Parameters
-
painter – the QPainter to paint with. sceneRect – the total bounding rectangle of the scene. exposedRect – the rectangle that needs to be painted. rowController – the row controller used by the view – may be 0. widget – the widget used by the view – may be 0.
Implemented in KGantt::DateTimeGrid.
◆ paintHeader()
|
pure virtual |
Implement this to paint the header part of the view.
- Parameters
-
painter – the QPainter to paint with. headerRect – the total rectangle occupied by the header. exposedRect – the rectangle that needs to be painted. offset – the horizontal scroll offset of the view. widget – the widget used by the view – may be 0.
Implemented in KGantt::DateTimeGrid.
◆ rootIndex()
QModelIndex AbstractGrid::rootIndex | ( | ) | const |
- Returns
- the current root index for this grid
Definition at line 45 of file kganttabstractgrid.cpp.
◆ setModel
|
virtualslot |
Sets the QAbstractItemModel used by this grid implementation. This is called by the view, you should never need to call this from client code.
Definition at line 30 of file kganttabstractgrid.cpp.
◆ setRootIndex
|
virtualslot |
Sets the root index used by this grid implementation. This is called by the view, you should never need to call this from client code.
Definition at line 40 of file kganttabstractgrid.cpp.
