Description
The property contains the point size of the font assigned to the selection as a numeric value.
If the text in the current selection contains sections with different font sizes, the instance variable :selFontSize contains the value NIL. This value represents an indeterminate state that the Xbase++ application may chose to visualize in its user interface. Some word processor applications use grayed controls to visualize conflicting properties in the current selection, for example.
