hi all,
lets say I have boxes as edit parts, and those boxes have names. when user
clicks and tries to add it to diagram, when user first clicked in pallette,
i should display a dialog box and ask for the name of this box. so, i have
this in getPalletteroot
tool = new DefaultPaletteToolEntry(new CreationTool(new
PortCreationFactory()), "In....
and as you see i implemented CreateRequest.Factory in PortCreationFactory,
and display dialog in getNewObject() and ask for name, however this doesn't
work because during this process this method is called for every pixel mouse
moves over parent.
so, how should I implement functionality I need?
thanx,
ozgur

small addition, the thing i described below, happens only when user clicks
cancel in dialog, this means i return null for getNewObject() and this
messes things up little. it works ok when user goes on and clicks ok on
dialog, in which case i return new object....
public Object getNewObject()
{
WNewArgument wna = new WNewArgument();
WizardDialog wd = new WizardDialog(null, wna);
if (wd.open() == WizardDialog.OK)
{
return new InputPortModel("asd", "asd");
}
else
return null;
}

sorry for third part but, i want to have this dialog when user just clicks
on pallette item, not when mouse moves over parent. it's clear to me that i
implemented this functionality in wrong place... where is the correct place?

If you were to continue using the CreationTool, one correct place is to do
this on Tool.activate(). However, why prompt the user before they have
clicked on the Graphical canvas? What if they activated the Tool be
accident?
You should convert to using PaletteTemplates, and the correct place will be
on the TransferDropTargetListener. On handleDrop(), you could prompt the
user for the name.
Dialogs suck. The best solution would be to generate a bogus name, and use
DirectEdit (perhaps you could invoke this immediately upon creation), and
have the user type the realy name.

Hi Randy!
Thanks for answers and idea about 'dialogs suck'. you're right, however, i'm
under heavy stress nowadays, i'll definetely consider in-place editing. the
thing i described was a very simplified version what i have, so it's not
just a label, it's a string some parts are allowed to edit, some parts are
not and so...
thanx again,
ozgur

Yeah, sometimes you need a dialog. Especially if the properties must be set
before the object can be instantiated in the model. If possible, the
properties in the dialog should be editable on the propertysheet too. I
agree the direct-edit is most effective on just a single attribute, like
"name".
