Introduction
“Give back the real Windows Look & Feel to Clarion applications!”
- SysTree is the 9th product in our series of common control wrapper
classes, taking you again one step closer to the above goal.
Clarion's built-in listbox works fine for most cases. But taking
a closer look, it's quite obvious that this control is no more state
of the art. If you want to give your users the controls they know
from many other applications (including the Windows Explorer, Outlook
Express, ...), SysTree is what you need!
What SysTree is
The main part of SysTree is the wrapper class for the tree-view
common control, written in 100% pure Clarion code. It allows you
to use tree-view controls, introduced by Microsoft with Windows
95, in your Clarion applications! This powerfull class implements
over 80 methods (17 of which are virtual event handlers), giving
you full control over all the styles, settings and events without
having to struggle around in the depths of api programming.
The accompanying templates make the class easy to use. You can add
a tree-view control to your application in less than a minute, without
having to write a single line of code (the items would still have
to be added, of course - an empty control doesn't really attract
users ;-)
And there's even more: there's another
control template called SysDirTree. As you might guess from
the name, it's a tree-view control displaying file system folders!
You can have your applications display an Explorer-like view of
the local drives on your computer, using the system icons. Again,
no hand written code is necessary. And since the SysDirTree class
is derived from the SysTree class, all the above mentioned options
are available for SysDirTree, too!
What SysTree is not
This is the most frequently asked question, and yet the answer
is no: SysTree does not support file browsing. I didn't
want to re-invent the (file browsing) wheel, but concentrate on
the main part: SysTree was designed to be a wrapper class for the
tree-view control, and this to the max!
It is, however, quite easy to load the tree-view control from a
file. Given the right database layout, a single, recursive procedure
of less then 10 lines of code is enough to load the data into the
control.
