RunScreen allows the user to control certain elements of your program at
- Selecting, Hiding and re-arranging the columns of a browse at
runtime. This is a common feature of many programs, and indeed is a
native feature in Clarion's ABC library. RunScreen offers an alternative
implementation of this feature. Read More...
- User settings are saved per user. You can save this in a datafile or
in an ini file. This means that each user can customize the display the
way he/she wants it.
Clarion already has browse column management in ABC. (Don't know how to
use it, see here
). So why use a different one? It comes down to a matter
of taste really, but these are the reasons we created a different one;
- Additional User-Interface features, like Drag & Drop columns and
Right-Click Hide-Column are supported.
- Supports not only Browse Controls, but List controls as well.
- The visual design of the management window shown to the user is
declared inside the ABC Class (called ListFormatManagerClass) inside
a Private method. This means the design will not conform to the
other visual aspects of your application. By contrast RunScreen
requires this procedure to be in your Application tree, so you have
complete control over it.
- The ListFormatManagerClass allows users to create multiple
different layouts for each browse. In our applications each user may
want a different format, but allowing them to create multiple
formats for a single browse is overkill for them. By contrast
RunScreen offers a simpler interface.
- We already have template code (like
Secwin) and hand-code in embed points that manage the which
columns are visible or not. So we needed a List Manager that worked
in conjunction with that code and which allowed other code to
control the visibility of certain columns. Also that code must work
on the correct column, even if the column has been moved by the
really interesting effect of having Runtime Column Management has been
that, as developers, we are more likely to add more fields to a browse,
even if those fields are hidden (ie have a width of zero) by default.
There is less need to exclude columns that have minimal usage, or which
clutter up the screen. We've found in our own apps that we're able to
cater for a wider variety of users, adding the columns that are only
applicable to a few users, while not cluttering up the browse for the
