[Oberon] Native Oberon, TextFrames.barW.

[Jörg Straube]

Hi Peter

The height of the title bar is called „menuH“. And it is dependent on the height of the default font.

„barW" is the width of the scroll bar along the left border of the text frame.
To make it visually appealing, the intersection of the horizontal title bar with the vertical scroll bar shall be a square.
Hence, „barW" is also dependent of the height of the default font.
