Detailed Description

Graphical line object that wraps a Line.

Member Function Documentation

applyToModel()

void GLine::applyToModel ( )

overridevirtual

Apply changes to the underlying model object.

Note

The base implementation does nothing and should be implemented in derived classes.

Reimplemented from GObject.

get()

Line* GLine::get ( )

overridevirtual

Return the object that is being wrapped by this class.

Note

Derived classes should change the return type of this method to match the type of the object that is wrapped by them.

Reimplemented from GObject.

handleChanged()

void GLine::handleChanged ( GObjectHandle *  handle )

overridevirtual

Called when a handle's position has changed.

The base implementation does nothing.

Parameters

handle

The handle that has been modified.

Reimplemented from GObject.

reloadFromModel()

void GLine::reloadFromModel ( )

overridevirtual

Update the graphical representation to match the object from the model.

Note

The base implementation does nothing and should be implemented in derived classes.

Reimplemented from GObject.

showHandles()

void GLine::showHandles ( bool  show = true )

overridevirtual

Display/hide the handles for this item.

The list of handles is dynamically allocated and it exists only while the handles are visible. This way, the handles do not take up memory when they are not used.

Note

The base version of this method implements only the deletion of handles, i.e. when show = true. Each subclass should implement this this method separately, optionally calling the superclass method but only as the last statement.

Reimplemented from GObject.
