How to load a form without a menu

[VPExplorer]

Hi,

I'm re-writing an application from another language, in VP. I finished designing the main form, which in the other language is also the main window. There's no menu, doesn't need to be.

The Tyros document explains how to load a form from a menu item. But how do you load a form, automatically, when the application starts?

In the taskWindow implementatio there is a predicate named onCreate. That predicate loads a mesageForm at start-up. You can do exactly the same with your own form.

Great, thanks Thomas.

Thomas, I've searched around for a TaskWindow implementation, and cannot find any such project.

Also searched through the example projects for instances of the use of onCreate, and tried different variations in the TaskWindow.pro for my specific project, but continue to get syntax errors.

If the form is called frmMyForm, can you show an example of a fact, predicate, and clause, which would activate and display frmMyForm?

Thomas,
It is not the onShow predicate ?

Hi,
A simple exemple :

Code: Select all

predicates
    onShow : window::showListener.
clauses
    onShow(_, _CreationData):-
        _MessageForm = messageForm::display(This),
        _MyForm = frmMyForm::display(This)
        .

Yes, sorry. It is onShow.

That clears it up, ok thanks.

Perfect, thanks.
