Arw_SetTextSize returns a value of 0 if the font size was successfully assigned, and a value of -2 if the specified object ID number is invalid. | |||
== Usage == | |||
<syntaxhighlight>Arw_SetTextSize(ObjectID, FontSize)</syntaxhighlight> | |||
Where: | |||
:'''ObjectID''' - a numerical expression specifying the object ID number. | |||
:'''FontSize''' - a numerical expression specifying the font size. | |||
==== | == Notes == | ||
* An object-specific ID number is assigned by [[Arw_New]], [[Arw_New_s]], [[Arw_New_self]] or [[Arw_New_self_s]] when the arrow object is created. | |||
* Use [[Arw_GetActive]], [[Arw_GetFirst]] or [[Arw_GetNext]] to get the object-specific ID number of an already created arrow. | |||
