void MythUIProgressBar::CopyFrom ( MythUIType * base )

protectedvirtual

Copy this widgets state from another.

void MythUIProgressBar::CreateCopy ( MythUIType * parent )

protectedvirtual

Copy the state of this widget to the one given, it must be of the same type.

Reimplemented from MythUIType.

Definition at line 186 of file mythuiprogressbar.cpp.

void MythUIProgressBar::Finalize ( void )

protectedvirtual

Perform any post-xml parsing initialisation tasks.

This is called after the widget has been created and it's state established by ParseElement() or CopyFrom(). A derived class should use this to perform any initialisation tasks which should occur after this point.
