.height defines the height of the entire notebook object with all ist elements. If the height is defined too small, a minimum value depending on the window system will be used. The height must not be 0 since the required height cannot be calculated.

In tablefield the attribute can have the value 0. This means that the Dialog Manager shall calculate the corresponding height so that all elements can be displayed in the respective directions without a scrollbar. If the tablefield height is set at 0, it will get so wide that all lines can be displayed completely in the object.

With the toolbar, .height (without index) defines the default value for the values not set by .height[class].

Remark for the IDM for Windows

The height of a poptext cannot be specified; the window system chooses a value depending on the font.
