IntuiTextLength

Return the length (pixel-width) of an IntuiText.

This routine accepts a pointer to an instance of an IntuiText structure, and returns the length (the pixel-width) of the string which that instance of the structure represents.

NOTE:

if the Font pointer of your IntuiText structure is set to NULL,

you'll get the pixel-width of your text in terms of the current system default font. You may wish to be sure that the field IText->ITextFont for 'default font' text is equal to the Font field of the screen it is being measured for.

IText

pointer to an instance of an IntuiText structure

Returns the pixel-width of the text specified by the IntuiText data

Would do better to take a RastPort as argument, so that a NULL in the Font pointer would lead automatically to the font for the intended target RastPort, rather than the system default font.
