Detailed Description

Text view widget, which allows the user to enter a large amount of arbitrary text (also useful for displaying large amounts of text in a read-only fashion)

Constructor & Destructor Documentation

hdi::core::TextView::TextView ( )

Constructs an empty TextView object.

Author
GW
Date
07/2014
Note
To test if a TextView object is empty, call isEmpty (hdi::core::Widget) on it
Empty TextView objects do not relate to any actual UI widget; they are designed to be "receivers" of some other TextView object via the overloaded assignment operator. Empty TextView objects are useless until such time (though it is safe to call any of their methods).
hdi::core::TextView::TextView ( const TextView view_)

Constructs a new TextView object from an existing TextView object (copy constructor)

Author
GW
Date

view_Existing TextView object
hdi::core::TextView::TextView ( const Rect frame_,
const std::string &  text_,
const bool  edit_ = true 
)

Constructs a text view, which can be editable or read-only.

Author
GW
Date

Parameters
frame_Frame for the text view
text_Default text in the view, as UTF-8
edit_Whether the text view is editable
virtual hdi::core::TextView::~TextView ( )
virtual

TextView destructor.

If you subclass TextView, you MUST overload this method yourself! If you don't and/or your clone() method does not return an instance of your TextView subclass, you will experience "object slicing" when adding the widget to a window.
Warning
The caller must manage the memory for the returned TextView object.

Implements hdi::core::Widget.

virtual

Convenience method to duplicate a TextView object, creating a new and identical UI element to the target (but not belonging to the same containing window)

Author
GW

A pointer to the new TextView object (and new UI element)
Warning
The caller must manage the memory for the returned TextView object.
