More Controls toolbar

Spin Button

Allows form users to choose a number by cycling

through the list of numbers. You can specify maximum,

minimum, default, and the step between numbers.

This control is not commonly used in Writer, as the

number is not displayed. In Calc, however, a Data tab

appears on the Control Properties dialog box, so you

can link the spin button to a cell.

Scrollbar

Creates a scrollbar, with a number of options to define

the exact appearance.

This control is not commonly used in Writer. In Calc, a

Data tab appears on the Control Properties dialog box,

allowing you to link the scroll bar to a cell.

Image Button

Behaves exactly like a push button, but displays as an

image. Choose the image in the Graphics option on the

General tab in the Control Properties dialog box.

Image Control

Only useful when the form is connected to a data

source and a field in the data source exists that can

hold images. You can add new images to the database

or retrieve and display images from it.

Date Field

Stores a date. You need to configure the earliest and

latest dates the field will accept, the default date, and

the date format. You can add a spinner.

Time Field

Works like a date field but specifies a time.

File Selection

Allows a user to select a file, either by typing the path

and name directly or by clicking on a Browse button

and choosing the file from a dialog box.

Numeric Field

Displays a number. You need to specify formatting,

maximum, minimum and default values. You can add a

spinner.

Currency Field

Works like a numeric field; additionally you can add a

currency symbol.

Pattern Field

Pattern fields are useful when the form links into a data

source. Specify an Edit Mask to restrict what a user

can enter into the field. Specify a Literal Mask to

restrict which data is displayed from the data source.

Group Box

The group box control has two different uses

depending on whether wizards are on or off.

If wizards are on, creating a group box launches the

Group Element wizard. This creates a group of options

buttons (in which only one may be selected at a time).

In most cases, using a group box is the best way to

create a set of option buttons.

If wizards are off, a group box is simply a visual box to

group together different controls. It has no effect on

the way the controls operate.
