详细描述

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.

Button {
    text: "Button"
}
					

Button is similar to the QPushButton 小部件。

You can create a custom appearance for a Button by assigning a ButtonStyle .

特性文档编制

isDefault : bool

This property holds whether the push button is the default button. Default buttons decide what happens when the user presses enter in a dialog without giving a button explicit focus.

注意： This property only changes the appearance of the button. The expected behavior needs to be implemented by the user.

默认值为 false .

menu : Menu

Assign a Menu to this property to get a pull-down menu button.

默认值为 null .
