Methods
| Signature | Description |
|---|---|
Action() → Action | Action returns the button’s activation action (/A on its widget), or nil if none is set or the action type is unsupported. |
SetAction(act: Action) | SetAction writes the button’s activation action (/A) onto its widget(s) — typically a SubmitFormAction, ResetFormAction, GoTo/URI or JavaScript action. |
SetAppearance(a: ButtonAppearance) → error | SetAppearance applies a ButtonAppearance to the push button: it writes the /MK characteristics (/CA, /RC, /AC, /TP) and regenerates the widget’s /AP with distinct /N (normal), /R (rollover), and /D (down) appearance streams. |
SetReadOnly(v: bool) | Sets the read only value. |
Value() → string | Returns the value. |
SetValue(s: string) → error | Sets the value value. |
