[wd17]Define Type

Hi,

Is it possible in Windev to define your own types (for a variable) ?

For example, in Delphi you can do something like this :

//define the type
Type
PossibleColors=(Red,White,Black)

//define a variable of that type
Var
Mycolor : PossibleColors

//use of the variable
If Mycolor = Red then showmessage('Color = Red')


is something like this possible in WD ?

Thx !

Hi Bart,

Sure and there's different ways to implement this:
- As a class
- An associative array
- As a structure
- As a composite variable
Check out the online help:

Hi Bart,
No!
Enumerations are not available in WX17. They will be available in WD18.

#pragma

ah thanks, great, it's the "nouveauté" 66 of WD18.
I'm a bit surprised that something common like this wasn't supported.

For the moment I will work with good old constant values.

Thx for the help !

Hi Pragma,

You're right... I didn't look at the sample more closely. Enumerations like in C# are indeed not available in pre-V18. But... Although not the same you could mimic similar behaviour by using associative arrays.

Here's an example:

aaColors is Associative array of string
aaColors = [["Red","Red"],["Blue","Blue"],["Green","Green"]]
MyColor is string = "Green"
IF NOT aaColors[MyColor] ~= "" THEN
    Info(Buildstring("The color chosen is %1", aacolors[MyColor]))
END

Cheers,

Peter H.
