\brief The FrameNavigator is a simple toolbar widget showing a numerical
|
|
representation of an integer timeline.
|
|
|
|
\details A FrameNavigator is a TFrameHandle viewer composed of a line edit
|
|
widget showing the current frame number, and a pair of directional
|
|
arrow buttons that move to adjacent frames.
|
|
|
|
\remark The text field actually visualizes the internal integer \p m_frame
|
|
\a +1
|
|
(e.g. when \p m_frame is 0 then 1 is visualized).
