Introduction to PowerBuilder
Naming
Controls
When you place controls on a
window, PowerBuilder automatically names them using standard
prefixes and a number to uniquely identify them. The full list of
controls and naming prefixes are as follows:
| Control Type |
Prefix |
| CommandButton |
cb_ |
| PictureButton |
pb_ |
| StaticText |
st_ |
| SingleLineEdit |
sle_ |
| EditMask |
em_ |
| MultiLineEdit |
mle_ |
| ListBox |
lb_ |
| TreeView |
tv_ |
| CheckBox |
cbx_ |
| RadioButton |
rb_ |
| DataWindow |
dw_ |
| DropDownListBox |
ddlb_ |
| DropDownPictureListBox |
ddplb_ |
| Picture |
p_ |
| Groupbox |
gb_ |
| Graph |
gr_ |
| OLE 2.0 |
ole_ |
| Vertical scrollbar |
vsb_ |
| Horizontal
scrollbar |
hsb_ |
| RoundRectangle |
rr_ |
| Rectangle |
r_ |
| Oval |
oval_ |
| Line |
ln_ |
| ListView |
lv_ |
The above list has
the default prefixes. If you want to have different prefixes, you
can change the defaults by selecting "Design/Options" and changing values in "Prefixes 1" and in "Prefixes 2". You can rename any of the
controls, but it's a good idea to keep the standard prefixes so
that it is easy to identify the type of object by looking at the
control name in the script. Remember the control names within a
window should be unique. That means, you can't have more than one
control with the same name in a window. You can have a control
with the same name in different windows. The names are case
insensitive. While naming, you should follow PowerBuilder naming
rules:
 |
Must start with a letter |
|
Can have up to 40 characters, but no spaces |
|
Are case insensitive (PART, Part, and part
are identical) |
|
Can include any combination of letters,
numbers, and all these special characters:
|
Dash |
|
Underscore |
|
$ Dollar sign |
|
# Number sign |
|
% Percent sign |
|
