\class Q3Button

\brief The Q3Button class is a compatibility base class of button
|
|
50 |
widgets

|

|
|
52 |
\compat
|
|
53 |
|
|
54 |
\bold{In new code, use QAbstractButton.}
|
|
55 |
|
|
56 |
To subclass Q3Button, you must reimplement at least drawButton()
|
|
57 |
(to draw the button's outline) and drawButtonLabel() (to draw its
|
|
58 |
text or pixmap). It is generally advisable to reimplement
|
|
59 |
sizeHint() as well, and sometimes hitButton() (to determine
|
|
60 |
whether a button press is within the button).
|
|
61 |
