Hi Folks,
I've run into a case where an image I am creating does not scale with its
parent window. Some background - I am trying to create and application to
process data stored within a file - much like any image data with a header.
However, I am not opening anything with a standard image format.
I have a selector panel than selected the kind of data I am reading, and lets
me select the file. Based on the header information in that file, I create a
window, view, image, image representation with the appropriate parameters, and
I can already create the window and draw the contents of my file to it. It
does this initial drawing properly.
The problem is, when I grab the edge of the window to resize it, the image
that's drawn to it does not reisze with the parent window. It maintains its
original size, and stays centered in the window view.
My initialization code for the GUI elements of that window is below. Is there
a flag I am missing somewhere in this, or do I need to handle view and image
resize updates in another routine ?
Thanks all.
