Question

Re: Explorer like user interface
You'll want to use the geometry management features in Forte.
These can be controlled using the WidthPolicy and HeightPolicy
attributes on FieldWidget (see p 160 of the Display Library manual).
You can set these in your code, or using the 'Size Policy' dialog
off the widget property sheet.
Do the following:
Create a Window class, get into the Window Workshop.
In the Window property sheet, set the Window Style to Resizable,
set Autosize Enabled.
Create your TreeView and ListView, group them into a GridField.
In the TreeView and ListView Property Sheets, under Size Policy,
set the Width Policy and the Height Policy to Parent for both
the ListView and TreeView. Also set a minimum size for each (in mils)
the minimum size will prevent you from getting too small a window.
For the GridField, also set the WidthPolicy and HeightPolicy to Parent.
You may also want top set the Column Weight to the ratio you want for
the sizing of the Tree and List, say 2:3.
Now the sizing will work. You'll just have to write the code
to get data in you TreeView and ListView. Looking at
the examples for outline field:
$FORTE_ROOT/install/examples/display/soutline.pex
is a good place to start, if you haven't done it before.
Good luck!

Hi,
I would like to design a window which is similar to Windows Explorer.
Treeview in the left side, listview in the right side. I should be
able to drag and expand the size of the treeview. How is this possible
in Forte? I tried to use STATE attribute of widgets, but did not
succeed. Could anyone suggest me how to go about it.
Thanks in advance,
Ramarao

Answer 1

Just to complete, here is a little sample in R3.F.2.0 done with
Treeview and listView.
Be aware that to give the user the possibility to resize the left
part, you should manage it yourself. If you use an outlinefield
instead, you can put WidthPolicy to seleted and then use FS_ROUTE
state to enable the user to resize it. But this occurs a bug with the
resize of the window. If you try this with the treeview, it will
be converted to FS_SELECTONLY which is nonsense here.
Also, don't forget that ListView only does Ascending Sort (Microsoft
does Ascending and Descending). So you should need to manage sort
yourself too.
Hope this helps,
