Mark Rivers object example
type: item
description: Greetings, While playing with Mark Rivers object example I noticed some interesting behavior. As he mentions in his example, Xmanager can't have the main event handler be an object method, but the event_pro keyword can! Here is my version of Mark's example. ;Begin example--------------------------------------------- function example::init base = widget_base(uvalue=self,xsize=100,ysize=100) void = widget_button(base,value='exit',event_pro='example::event') widget_control,base,/realize xmanager,'example::init',base,/no_block return,1 end pro example::event ;no need for an event variable, the implicit self is the event ;structure!!! widget_control,self.top,/destroy end pro example__define data = fltarr(30) t = {example,data:data} end ;end example--------------------------------------------------- I have only tried this out on an alpha, but if this really is a feature of 5.0 then it opens up some interesting programming possibilities. -Ronn Kling Ronn Kling Consulting
