Text scaling inside classes

asked Jun 29 in Bug by agillesp (640 points)

I don't know whether this is a bug or just me abusing class diagrams.

The following snippet used to result in a class containing two columns that were vertically aligned:

@startuml
skinparam
ClassAttributeFontName "Courier New"
class
MyClass {
  VeryVeryLongNameIndeed 1
  Short                  2
}
@enduml

The result now is some strange horizontal scaling on the second line:

I am currently using version 1.2018.08, although several versions before this would also do the same thing.

Is this a bug?

Maybe you can use the following example:

@startuml
hide empty members
skinparam ClassAttributeFontName "Courier"
class MyClass {
  VeryVeryLongNameIndeed\t1
  Short\t\t\t2
}
@enduml

Is this what you are expecting ?

Thanks for your response.

It does help in a lot of cases, although changing from a TrueType font (Courier New) to a bitmap font (Courier) also works without using escaped tabs.

I notice that there is a similar issue with notes, except there the "\t" solution doesn't work as it just inserts the literal characters "\t" into the note.

I have a suspicion there is an underlying bug in there somewhere, but the behaviour is not easy to understand.

It is possible this issue may be related to this one:

It seems to occur only with TrueType fonts on Windows.
