Converting Delphi 7 property editor to Delphi XE2

由 拥有回忆 提交于 2019-12-07 19:10:27
问题 First of all, I have never written a property editor from scratch, but had some help with one in another question. Refer to the accepted answer there. This was in Delphi 7, and now I have started using XE2 and I have to make sure my property editor is compatible with both 7 and XE2.

由 半城伤御伤魂 提交于 2019-12-06 11:39:52
