\qmltype ButtonStyle
\inqmlmodule QtQuick.Controls.Styles
\since 5.1
\ingroup controlsstyling
\brief Provides custom styling for Button.
You can create a custom button by replacing the "background" delegate
of the ButtonStyle with a custom design.
Example:
\qml
Button {
text: "A button"
style: ButtonStyle {
background: Rectangle {
implicitWidth: 100
implicitHeight: 25
border.width: control.activeFocus ? 2 : 1
border.color: "#888"
radius: 4
gradient: Gradient {
GradientStop { position: 0 ; color: control.pressed ? "#ccc" : "#eee" }
GradientStop { position: 1 ; color: control.pressed ? "#aaa" : "#ccc" }
}
}
}
}
\endqml
If you need a custom label, you can replace the label item.
