Detailed Description

Button widget, which can be either the default button, cancel button, or normal button in a dialog, and optionally contain an image.

Constructor & Destructor Documentation

hdi::core::Button::Button ( )

Constructs an empty Button object.

Author
GW
Date
09/2013
Note
To test if a Button object is empty, call isEmpty (hdi::core::Widget) on it
Empty Button objects do not relate to any actual UI widget; they are designed to be "receivers" of some other Button object via the overloaded assignment operator. Empty Button objects are useless until such time (though it is safe to call any of their methods).
hdi::core::Button::Button ( const Button button_)

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

Author
GW
Date
09/2013
Parameters
button_Existing Button object
hdi::core::Button::Button ( const Point loc_,
const std::string &  title_,
const WindowType  containerType_ 
)

Constructs a button using a location and window container type; height is fixed.

Author
GW
Date
09/2013
Parameters
loc_Top-left location of the button
title_Title of the button, as UTF-8
containerType_Type of window that will contain the widget
Note
The containerType_ argument is necessary for this constructor because it computes the ideal width for the new button from the initial button title string. However, Illustrator uses different font sizes for different types of windows, and we can't correctly compute the width without knowing what font size to use.
hdi::core::Button::Button ( const Point loc_,
const std::string &  title_,
const double  width_ 
)

Constructs a button using a location and width; height is fixed.

Author

Date

Parameters
loc_Top-left location of the button
title_Title of the button, as UTF-8
width_Width of the button
hdi::core::Button::Button ( const Rect frame_,
const std::string &  title_ 
)

Constructs a text button of a specific size.

Author

Parameters
frame_Position and size of the button
title_Title of the button, as UTF-8
hdi::core::Button::Button ( const Rect frame_,
const ImageIDs imageIDs_ 
)

Constructs an image button of a certain size.

Author

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