Detailed Description

A graphical text object that wraps a Text.

The GText has a child item of type GDisplayText that displays the text to the user and handles text editing.

GText is responsible for:

• synchronization with the model
• manipulation of GDisplayText flags to enter/leave edit mode
• any interaction that doesn't involve text editing, e.g object selection, displaying context menus, etc.

Member Function Documentation

applyToModel()

void GText::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()

Text* GText::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.

hoverEnterEvent()

void GText::hoverEnterEvent ( QGraphicsSceneHoverEvent *  event )

overrideprotected

Hide cursor guides.

hoverLeaveEvent()

void GText::hoverLeaveEvent ( QGraphicsSceneHoverEvent *  event )

overrideprotected

Show cursor guides.

mouseDoubleClickEvent()

void GText::mouseDoubleClickEvent ( QGraphicsSceneMouseEvent *  event )

overrideprotected

On double left click: enable editing, change to IBeam cursor and hide cursor guides.

reloadFromModel()

void GText::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.
