TuiButton

Draws a button that calls your procedure when the user presses Enter on it.

Syntax

type TuiButton extends TuiWidget
    as ustring label
    as int32 id
    as TuiOnClick onclick
    as TuiStyle normal, active
end type

Description

A focusable button whose callback is a PLAIN procedure pointer. For a callback that captures something, use TuiButtonOf -- a capturing lambda cannot be converted to a procptr at all, which is error 355.

Example

#import "std/numeric"
#import "std/tui"
using tui, numeric

sub OnSave( byval id as int32 )
    print "saved, button id "; id
end sub

dim as TuiButton b
b.label = "Save"
b.id = 1
b.onclick = @OnSave
b.SetFocused( TRUE )

dim as TuiEvent e
e.kind = TUIEVENT_KEY : e.key.code = TUIKEY_ENTER
print b.HandleEvent( e )          '' true, and OnSave ran
