Feature Request: Multi-Button MessageBox Support in Objo

manuelmrtz

I would like to request a "MessageBox" function in Objo that supports multiple buttons.

For example:

Var result = MessageBox(
    "Do you want to save your changes?",
    "Confirm",
    ["Save", "Don't Save", "Cancel"]
)

The function should return which button the user clicked.

It would also be useful to support common combinations such as:

OK
OK / Cancel
Yes / No
Yes / No / Cancel
Retry / Cancel

Optional icons such as Information, Warning, Error, and Question would also be helpful.

This would make it much easier to create confirmation and decision dialogs without building a custom window each time.

Thanks for the detailed suggestion. The good news is that you can already do this today with the MessageDialog class, which supports up to three custom-caption buttons and tells you which one was pressed:

Var dlg As New MessageDialog
dlg.Title = "Save Changes?"
dlg.Message = "Do you want to save your changes before closing?"
dlg.Icon = MessageDialogIcon.Caution
dlg.ActionButtonCaption = "Save"
dlg.AlternateActionButtonCaption = "Don't Save"
dlg.CancelButtonCaption = "Cancel"

Var result As MessageDialogButton = dlg.Show()

If result = MessageDialogButton.Action Then
    # Save the document
ElseIf result = MessageDialogButton.Alternate Then
    # Discard the changes
Else
    # Cancel — keep the document open
End If

On the desktop, Show() waits for the user to respond and returns MessageDialogButton.Action, .Alternate, or .Cancel; pressing Escape or closing the dialog counts as the Cancel button whenever one is present. The icon values are MessageDialogIcon.Note (information), .Caution (warning), .Stop (error), and .Question, and there's an Explanation property for secondary text under the main message. In web apps the same class exists with one difference: Show() returns immediately and the chosen button arrives in the Dismissed(button) event instead.

Full reference: MessageDialog.

You're right that the quick MessageBox(message) form is single-button only - it shows one OK button and returns Nothing. I've logged a feature to give MessageBox multi-button overloads that return the pressed button: feedback.objo.dev/feature/1694.

Thanks for the explanation. I wasn’t aware that MessageDialog already supported custom buttons and returned the selected button.

In that case, I think MessageDialog already covers exactly what I was looking for, so I don’t think we really need to modify MessageBox.

I like having MessageBox() as the simple one-button option and MessageDialog for situations where you need more control.

You’re doing great work with Objo, and I’d rather see your development time focused on more important features and improvements instead of duplicating functionality that already exists.

Thanks again for the explanation and for all the work you’re putting into Objo!

This has now been implemented for the next release.
