rhs	The right hand side of the initialization.

Member Function Documentation

void retro_button::down ( void ) [private]

The down method is used to perform the processing attendant to the button going down. It switches images and moves the label slightly.

Definition at line 183 of file retro_button.cc.

bool retro_button::enter_callback ( const _GdkEventCrossing * event ) [private]

The enter_callback method is used to handle the enter signal passed to us by the parent (base) class released signal. The constructor subscribes to the signal.

Definition at line 137 of file retro_button.cc.

bool retro_button::leave_callback ( const _GdkEventCrossing * event ) [private]

The fubar method is used to to handle the leave signal passed to us by the parent (base) class released signal. The constructor subscribes to the signal.

Definition at line 159 of file retro_button.cc.

retro_button& retro_button::operator= ( const retro_button & rhs ) [private]

The assignment operator. Do not use.

Parameters:

rhs	The right hand side of the assignment.

bool retro_button::pressed_callback ( const _GdkEventButton * event ) [private]

The pressed_callback method is used to handle the pressed signal passed to us by the parent (base) class pressed signal. The constructor subscribes to the signal.

Definition at line 77 of file retro_button.cc.

bool retro_button::released_callback ( const _GdkEventButton * event ) [private]

The released method is used to handle the released signal passed to us by the parent (base) class released signal. The constructor subscribes to the signal.

Definition at line 96 of file retro_button.cc.

sigc::signal<void> retro_button::signal_clicked ( void ) [inline]

The signal_clicked method is used to obtain the signal that will be issued when the button is clicked.

Definition at line 57 of file retro_button.h.

sigc::signal<void> retro_button::signal_released ( void ) [inline]

The signal_released method is used to obtain the signal that will be issued when the button is released (toggle buttons only).

Definition at line 63 of file retro_button.h.

void retro_button::up ( void ) [private]

The up method is used to perform the processing attendant to the button going up. It switches images and moves the label slightly.

Definition at line 191 of file retro_button.cc.
