Working With Dialogs
uses the property RADIO but has the Indirect check box marked. The property
FIRST, SECOND, or THIRD is set to the check box state based on the setting of the
radio button.
Scrollbar on left side
On a scrolling field control, places the scrollbar on the left instead of the right.
(Usually used with the Right-To-Left Reading check box below.)
Integer
Restricts end users to entering only integers in this control.
Right-To-Left Reading
Indicates that the text in this control is in a language that is read right to left.
Has Border
Displays a group box frame around the radio buttons in a radio button control.
Check Value
If the end user marks the control, the value of the property in the Property field is
set to this value.
Control Attributes
Transparent
Makes the background of the control transparent.
Format Size
Tries to format displayed text as a number representing a count of bytes. The
control's text must be set to a number in units of 512 bytes. KB, MB, or GB is added
to the end of the text depending on how large the number is.
No Prefix
Displays any & (ampersand) characters in the control's text. Otherwise, &
characters do not appear and cause the next character to be underscored.
Users Language
Makes the text control use fonts created in the end user's default UI codepage. If
this is cleared, the fonts are created in the database's codepage.
No Word Wrap
Text is not wrapped to fit the control area. Instead, it is clipped at the right edge of
the control.
Multiline
Lets an edit field control accept multiple lines of text. If this is cleared, it accepts
only a single line.
Image Handle
Obtains the image from a handle rather than from the Binary table.
Icon Control
Replaces the control's text with an icon. The control's text is used as a key to the
Binary table to point to the icon data.
Pushbutton
(Check Boxes and radio button groups only.) Draws the control as if it were a
pushbutton, although its behavior is not changed.
Fixed Size
Prevents the image associated with the control from being scaled to fit the control
size. Instead, the image is cropped or centered in the control.
