Excelent! Thanks Jan.

This works and I can place a rectangle behind it for a border and scroll the
contents as well with the mouse. .

SWEET!

I'll post a turnkey for anyone that wants to play with this idea.

I was pondering if that would work the other day. In c# there is a thing
called Panel, it is the Container for C# BUT it has an autoscroll bar
feature so that you can put a control on the panel that might grow beyond
the defined width and height.
So I thought the same thing could possibly be done with a subform as you
have done.

It would be convenient to have a sample<g>

Cool, I will take a look.
Thank you,

Greg Hill

Here you go, very rough, but works great.

It does the trick don't it<g>
I don't see drawbacks do you?

The only issue that I have at this time, is the forms "activecontrol" does
not switch to the "subform".
When focus is on the subform, the parent form's activecontrol is the
pushbutton.

Bug maybe ?? Is a subform considered a control ?? I use the activecontrol
alot in global key routines.

I think that it is WAD, you will probably have to write a function for the
enterkey at the subform level or maybe a simple loop that will add an onkey
event to each entryfield. I wonder how menus respond or even if they can be
attached. I will check.
By the way, I found it a bit frustrating that one would have to use the
mouse to re-gain focus to the parent for or vice versa, so I think the
solution for that would be to decide which object in the zorder would be the
last one and then for that objects onLostFocus do something like following:

this.parent.activeControl.setFocus() // from subform
this.s.activeControl.setFocus() // from subform

What do you think?

so I think the solution for that would be to decide which object in the
zorder would be the last one and then for that objects onLostFocus do

and the first too...for shift tab

let me think about this, kind of a fun challenge though eh?

A subform is not a control, it's literally another form. It's subclassed
(as I understand it) from the actual form class, but has special
modifications in the subclass. So no, it wouldn't be the parent form's
activeControl.

Tks Ken for your input, makes sense, but it is a child of the parent, and
when it get's focus, don't you think that it should be the active
"form"/"control" ??

I am not sure if it should or not ... while it does need/require a
PARENT property (which most forms do not), it is still a form, not a
standard "control".

Ken, do you know if the subform is anything more than just an ordinary
form with a behind-the-scenes setParent() to assign it to its "parent" form?

My understanding is that it is subclassed from the main form class, has
some minor changes (requires the parent property and you can pass it a
title if I am remembering correctly), and cannot be run as a modal form.
I cannot really recall what else.

It has to be different than using setparent() on a regular form, There are
alot of focus issues with using setparent() that don't exist with the
subform.

One other area,,,press <ctrl>W when focus is on the subform and it closes,
leaving the parent form open.
Any idea how to get around that ?

I forgot to mention that menus can easily be controled too by enabling and
disabling their items.

Example:
When the focus goes to parent form, the onGotfocus event can do the
following

form.root.menu3.enabled = false // this will disable the shortcut keys
assigned to the menu too.

Greg Hill

[Glenn Johansen]

This does work, stand by, I think I found a way to throw away the CTRL-W
keystroke without the menu.

Try running this version of the form and scrolcnt.mnu together.
By the way you can arrange this menu in a more pleasing way.

In the simple instance of this test form, this works perfect. Will not
work for me in production, but I have a new key handler that I will
replace for subforms vs regular forms. I do global key trapping for all
keystrokes on all forms.
-glenn

What won't work in production??

Jan

[Glenn Johansen]

I should have re-worded that.
I was refering to the fact that I was using the on key label command in this
test form and would have to remove those lines and check for the ctrl-w in
my forms onkey routine.

This is rather cool eh? I have already implemented this on a bunch of forms.
Makes it much easier to layout forms with LOTS of fields. Just scroll and
keep going......
