Spinbuttons, like sliders, are widgets that allow a user to change the numeric value in the cell by interacting with a widget. The value of spinbuttons can be changed either by typing a new number into the text box or by clicking on the arrow buttons. If the buttons are clicked and held, the numeric value will spin, incrementing or decrementing depending on the arrow being held.
The properties of the spinbutton can be altered with the Properties menu item in the context menu which appears when the mouse cursor is placed over the spinbutton and one of the secondary mouse buttons is pressed.
Spinbuttons have five properties which can be configured: the worksheet cell whose value will be altered by the spinbutton, the minimum value when the thumb is at the top of its channel, the maximum value reached when the thumb is at the bottom of its channel, the smallest increment of change which is the change caused by clicking on the arrows, and the page increment which is the change which occurs when the channel is clicked.
The "Link to:" field allows the user to select a cell that will be changed in response to changes in the state of the widget. A user can type the name of a cell in the text box or may click in the text box to activate it and then click on the worksheet to select the desired cell and Gnumeric will automatically add a reference to the cell.
The other properties can be changed either by typing a new number into the text box or by using the up and down arrows to increment or decrement the width number.
