Dear Michel
Your first command works fine on 1.4. What you suggested has already been done there. Although, you
probably should call StdCmds.InitLayoutDialog first (to avoid a NIL-deref trap if the layout dialog
had not been opened manually before).
I do not understand the problem with your second command, but maybe I am missing what exactly it is
you try to achieve. In both version (1.3.3 and 1.4) it seems to work fine for me.
Note that StdCmds implements a user interface, this is the stuff needed to drive dialogs and menus
and the like. Hence, there may be some underlying assumptions that hold for user interfaces but not
when using StdCmds as a programming interface. When you "import" StdCmds as an API what you can do
is scripting user actions in the GUI. As far as my experiments showed, using your IncSize command
has exactly the same effect as opening, editing and applying the corresponding dialog manually.
StdCmds.InitSizeDialog evaluates the current state (view type, selection and so on) of the front
window to set the value in the dialog. Since I do not know exactly in which context you tried to
apply your command, it may be hard for me to reproduce your problem.
Best regards,
Wolfgang Weck
