.SH DESCRIPTION
The QPushButton widget provides a push button with a text or pixmap label.
.PP
The push button (command button in Windows parlance) is perhaps the most central widget: Push it to command the computer to perform some action.
.PP
Being so central, the widget has grown to accomodate a great many variations in the past decade, and by now the "comand button" chapter of the Microsoft style guide shows about ten different states of Windows push buttons, and the text implies that there are dozens more when all the combinations of features are taken into consideration.
.PP
The most important modes or states are, sorted roughly by importance: 
.TP
Available or not ("grayed out", disabled).
.TP
Standard push button or toggling push button.
.TP
On or off (only for toggling push buttons).
.TP
Default or normal. The default button in a dialog can generally be "clicked" using the Enter or Return key.
.TP
Auto-repeat or not.
.TP
Pressed down or not.
.PP

In Qt, the QButton class provides most of the modes and other API, and QPushButton provides GUI logic. See QButton for more information about the API.
