Abstract

In a Presentation Manager* (PM) application, the limits of the screen is one of the challenges a programmer must face. Because PM applications are window based, sizing and positioning of controls used within an application are an area of concern. With the limited availability of screen real estate, control space requirements must be considered during the design of an application. One area of control usage is for image selection.

Image Selection from Within a Presentation Manager Application

      In a Presentation Manager* (PM) application, the limits of the
screen is one of the challenges a programmer must face.  Because PM
applications are window based, sizing and positioning of controls
used within an application are an area of concern.  With the limited
availability of screen real estate, control space requirements must
be considered during the design of an application.  One area of
control usage is for image selection.

      An image selection control may not only need to display the
image to be selected, it may need to display a brief description of
the image.  The challenge then becomes, first, how to display the
image and its description so that selection of a different image can
be made and, second, how to accomplish the first taking as little
screen real estate as possible.  A number of controls have been
defined to allow single item selection -- the listbox, the combobox,
and the popup menu are a few.

      The display of an icon or bitmap is something that can be done
using a STATIC control.  However, there is no control that allows
both the display and selection of an image to be performed in a
screen real estate efficient manner.

      The first control that comes to mind when presenting the user
with a list to select from is the listbox.  A list of items is
presented to the user and selection from the list can be made.  With
the owner draw capability of the listbox, both the image and its
description can be displayed to the user.  Unfortunately, the listbox
is a control that takes a fair amount of screen real estate.

      To save real estate, but retain the ease of use that is
provided by the listbox control, the combobox may be used in its
place.  The draw bac...
