LISTBOX Statement

Summary: Syntax

LISTBOX id, x, y, width, height[[,style]]

This statement defines a list box belonging to the LISTBOX class. It creates a rectangle that contains a list of strings (such as filenames) from which the user can make selections.

The id field takes a unique integer value that identifies the control.

The x and y fields take integer values that specify the x and y coordinates of the upper-left corner of the control. The horizontal units are 1/4 of the dialog base width unit; the vertical units are 1/8 of the dialog base height unit. The current dialog base units are computed from the height and width of the current system font. The GetDialogBaseUnits function returns the dialog base units in pixels. The coordinates are relative to the origin of the dialog box.

The width and height fields take integer values that specify the width and height of the control. The width units are 1/4 of the dialog base width unit; the height units are 1/8 of the dialog base height unit.

The optional style field can contain any combination (or none) of the following styles:

WS_BORDER

WS_VSCROLL

These styles are described in the list of window styles following the description of the STYLE statement on page 171.

In addition to these styles, the style field may contain any combination (or none) of the LISTBOX-class styles described in the list of control styles on page 194. Styles can be combined using the bitwise inclusive OR operator.

Summary: Comments

The x, y, width, and height fields can use the addition operator (+) for relative positioning. For example, 15 + 6 can be used for the x field.

The default style for LISTBOX is LBS_NOTIFY, WS_VSCROLL, and WS_BORDER.
