General Properties (Cont.)
Input Mask
This field allows you apply a mask to user input on the panel.
Note: This button property is available for Text Input buttons only.
An input mask allows you to force the user to enter the correct type of
characters (numbers vs. characters), suggest a proper format with fixed
characters, to change or force character case, to create multiple logical fields
that act as a single field, to specify a range of characters / numbers for each
field, to set the input as required or optional, and/or fill the field from the right or
the left.
The following sections describe the various types of input masks that can be
used:
• Input Mask Characters - page 252
• Input Mask Ranges - page 253
• Input Mask Next Field Characters - page 253
• Input Mask Operators - page 253
To define a literal, enter any character other than those shown in the topics
above, including spaces and symbols.
A back-slash (‘\’) causes the character that follows to be displayed as the literal
character. For example, \A is displayed as just A.
Left
Position values. The Left and Top rows indicate the position of the selected
button, in pixels, relative to the upper-left corner of the Design View window.
• You can edit these fields to apply specific positioning info for the button.
• Note that if you select the button and manually move it around on the page,
these values constantly update to indicate the button's current position.
List Column
An integer value representing the total number of columns in the List Box
button.
Note: This property is available for List Box buttons only.
Note: This property is read-only and cannot be edited. In unmanaged mode
this property is visible (but still read-only) for the unmanaged subordinate but-
tons. This way you can keep track of which row the button is identified with.
A list box column contains one or more subordinate buttons of the same width,
justified vertically. The number of subordinate buttons in a column depends on
the number of rows defined for the list box. The width of the first column is
determined at creation by the width of the list box control.
• At creation, one subordinate button is created automatically.
• The maximum number of columns that can be set/created is
• 10, and the minimum is 1.
See the List Box Buttons section on page 195 for details.
List Column Padding
List Column Padding - An integer value indicating the number of pixels
between columns of buttons.
Note: This property is present only when the List Box is in Managed Mode.
See the List Box Buttons section on page 195 for details.
List Display A string formatted as a space-delimited list of table column numbers in a List
Box Button that the columns of the List Data Table are assigned to.
Note: This button property is available for List Box buttons only, and only when
a List Table Port is assigned.
See the List Box Buttons section on page 195 for details.
