Feature Request: TPanel with border contour

[jordiperezartigues]

I cannt find any way to warp some components in a group, somewyhing like a panel with border and lie static, not movable.
Something like TPanel(tRect, title) that draws the border, and ready to insert TViews on it.

Hola, Jordi!

If I understood you right, you can achieve this by using a plain TView with the ofFramed option set.

For example, if we modify the hello.cpp sample application like this:

void THelloApp::greetingBox()
{
    TDialog *d = new TDialog(TRect(25, 5, 56, 17), "Hello, World!");

    TView *panel = new TView(TRect(16, 2, 29, 10));
    panel->options |= ofFramed;
    d->insert(panel);

    d->insert(new TStaticText(TRect(2, 5, 14, 6), "How are you?"));
    d->insert(new TButton(TRect(16, 2, 28, 4), "Terrific", cmCancel, bfNormal));
    d->insert(new TButton(TRect(16, 4, 28, 6), "Ok", cmCancel, bfNormal));
    d->insert(new TButton(TRect(16, 6, 28, 8), "Lousy", cmCancel, bfNormal));
    d->insert(new TButton(TRect(16, 8, 28, 10), "Cancel", cmCancel, bfNormal));

    deskTop->execView(d);
    destroy(d);
}

We get the following result:

If the dialog window is resizable, then you would have to set the view's growMode accordingly.

Salutacions!

That works, to group some components when i have a lot of different naturity.

If i want to change the background color in the TView, how i do?

Another question, when i do: this->insertWindow(newWindow) from the main TApplication
Can i later recover the window? to know if i have something atached or not?
this->getWindow() or this->last() can help?

Because of the way this is implemented, the color of the TView and the border around it will always be the same as the color of the window's frame. In order to have a specific color for the border, you have to create a custom class. However, getting that to work as expected would be quite complex because you must bear in mind that the background color is also part of some palette entries of the views used in dialogs (e.g., TButton's shadow), so changing the color of this view won't automatically change the color of views that you place on top of it.

It depends on how many windows you have and what your intent is. For example, if you just want to see whether a window already exists, the idiomatic solution is to use a custom broadcast event that is handled just by your custom window class. Here's a section from the Turbo Vision 2.0 Programming Guide (page 168) that explains this. It's in Pascal, but the concepts are the same:
