How to get a new module name from the Delphi open tools API

Question

I wrote a wizard in Delphi XE and it works fine. However, I have not yet figured out how to access the generated unit name by default (or form name or project name) that Delphi OTA can create.

In my old-style wizard, I was able to call ToolServices.GetNewModuleName to find the available unit and form name that I could use when creating the associated source files. What is equivalent in the open tools API today?

According to the comments of the ToolsAPI module, I have to return an empty value from the IOTAModuleCreator.GetImplFileName method so that Delphi will generate the file name. I am returning an empty string from this method, but still cannot see where I can access the file name that Delphi generates.

Answer 1

There is a special method for obtaining a new form and unit name:

(BorlandIDEServices as IOTAModuleServices) .GetNewModuleAndClassName ('', UnitIdent, FormName, FileName);

I used in a few examples and it seems to work fine.

Answer 2

The IOTAModuleCreator.NewImplSource method has a parameter ModuleIdent, this is the name of the unit.

Answer 3

In my tests, it works as you expected (the ModuleIdent parameter in the ModuleIdent method gets the name of the new device). Check your implementation again, especially make sure that:

• IOTACreator.GetUnnamed returns True
• IOTACreator.GetExisting returns False
• IOTACreator.GetCreatorType returns the corresponding identifier ( sUnit , sForm , etc.). I'm not sure about this, but it can be important.

Here is a working example. I just checked it and the code still works as expected in Delphi XE.
