|
|
|
|
The push button is perhaps the most commonly used widget in any graphical
|
|
user interface. Pushing (or clicking) a button commands the computer to
|
|
perform some action or answer a question. Common examples of buttons are
|
|
OK, Apply, Cancel, Close, Yes, No, and Help buttons.
|
|
|
|
\qml
|
|
Button {
|
|
text: "Button"
|
|
}
|
|
\endqml
|
|
|
|
Button is similar to the QPushButton widget.
|
|
|
|
You can create a custom appearance for a Button by
|
|
assigning a \l {ButtonStyle}.
