It is possible in REALbasic to have variable variables, similar to
what PHP has with the $$ notation? For instance, can I have a
variable that holds a string that is the name of another variable or
property and somehow access the property.
Specifically, I want to check for blank edit fields in a window. The
edit fields are all named "XXXEditField". If the field is blank then
the label, named "XXXLabel" should be in red and the first blank
field should have the focus. So far my code looks like this:
for i = 0 to self.ControlCount - 1
if self.Control(i) isa EditField then
if EditField(self.Control(i)).Text = "" then
if not foundFocus then
foundFocus = true
RectControl(self.Control(i)).SetFocus
end if
dim controlName as String = Control(self.Control(i)).Name
dim labelName as String = Replace(controlName, "EditField",
"Label")
// This is where I would somehow set self.$$labelName.Color to
red.
end if
end if
next
Thanks,
Chuck Ross
