Delphi XE/Windows7: why do VCL controls look different in an MDI application?

Question

Delphi XE / Windows 7.

Create a new VCL application, put a TCombobox on your form.

Create a new MDI application, do the same thing.

Why do the controls look different and how can I solve?

Other controls behave the same way. The same thing happens when I place controls on my mdi child forms in the MDI application.

Answer 1

The MDI application template in XE (and earlier versions) has runtime themes disabled. Simply enable it in the project options to resolve the difference.

This setting in the MDI application template was modified in XE2.
