Re: [Plib-users] Question re PUI sizes & frames

[John F. F. <joh...@cy...>]

James,

	If I remember correctly, PUI uses pixels as its units of distance.  The 
origin is the lower left-hand corner of the screen (or group), the x-axis 
extends to the right, and the y-axis extends upwards.

	Yes, you do have to create the frame first, before creating the buttons. 
 It is possible, though, to resize the frame after the buttons have been 
created.

Subject:	[Plib-users] Question re PUI sizes & frames


Hi,

I'm making some progress on modifying PUI to work with VR, but have a
couple more questions.  After a few modifications (such as replacing the
bitmapped text with GLUT vector fonts), I've got groups containing buttons
and such that I can move around & rotate at will.  Now I want to add a
nice frame around a group, but it seems that I have to create the frame
before creating the objects that go in it.  IOW the code needs to look
something like

   group = new puGroup (size...)
   frame = new puFrame (x1, y1, x2, y2);
   button1 = new puButton (x, y, label);
   button2 = new puButton (x, y, label);
   group->close ();

The problem is how to know the dimensions for frame before I create at
least one button, and find its size?

That leads to a larger question: what does PUI use as its internal
coordinate system?  At some point I'll need to add scaling of the PUI
coordinate system to the VR one, so that the menus appear at virtual world
sizes.  I'd rather not do this by trial & error, but I don't understand
the internal coordinates from the code.

Thanks,
James
