NSAlertMBS.addButtonWithTitle(title as string) as Variant

// make dialog
Var a as NSAlertMBS = NSAlertMBS.alertWithMessageText("Hello World", "First Button", "Second Button")

// add button
Var thirdButton as NSButtonMBS = a.addButtonWithTitle("Third Button")

// and show dialog
call a.runModal

Buttons are added from right to left (for left to right languages).
Returns NSButtonMBS object.

Some examples using this method:

• /MacCocoa/NSAlert Test

NSAlertMBS.beginSheetModalForWindow(win as DesktopWindow)

If the alert has an alertStyle of NSCriticalAlertStyle, it will be shown as a "critical" sheet; it will otherwise be presented as a normal sheet.
Calls later SheetDidEnd event with the result.

Please keep a reference to the dialog object alive to avoid trouble.
e.g. store reference in parent window, global property or app property.

• beginSheetModalForWindow(win as NSWindowMBS)
• beginSheetModalForWindow(win as window)

NSAlertMBS.beginSheetModalForWindow(win as NSWindowMBS)

NSAlertMBS.buttons as Variant()

Var a as NSAlertMBS = NSAlertMBS.alertWithMessageText("Hello World", "First Button", "Second Button")
Var buttons() as Variant = a.buttons

for each b as NSButtonMBS in buttons
  MsgBox b.title
next

Returns NSButtonMBS array.

NSAlertMBS.close

The SheetDidEnd event will not run.

NSAlertMBS.Constructor

Use properties to configure the dialog.

NSAlertMBS.Destructor

NSAlertMBS.layout

Can be used to indicate that the alert panel should do immediate layout, overriding the default behavior of laying out lazily just before showing panel. You should only call this method if you want to do your own custom layout after it returns. You should call this method only after you have finished with NSAlert customization, including setting message and informative text, and adding buttons and an accessory view if needed. You can make layout changes after this method returns, in particular to adjust the frame of an accessory view. Note that the standard layout of the alert may change in the future, so layout customization should be done with caution.

NSAlertMBS.runModal as Integer

Var a As New NSAlertMBS

a.messageText = "Should be do it?"

// OK button is added by default
Var e As Integer = a.runModal

NSAlertMBS.SetTextAlignment(value as Integer)

on macOS Big Sur and later, the default alignment is center.
If you show multiple lines of text, it may be easier to read with left alignment.

This calls layout method to layout the dialog.

See NSParagraphStyleMBS or NSTextMBS class for the alignment constants.
