Delphi XE2: Possible to instantiate a FireMonkey Form in VCL application?

由 a 夏天 提交于 2019-11-27 07:06:51
Prior to Delphi XE2, we have VCL only to create GUI apps. Delphi XE2 states that: Caution: FireMonkey (FMX) and the Visual Component Library (VCL) are not compatible and cannot be used in the same project or application. That is, an application must be exclusively one or the other, either FireMonkey or VCL. The incompatibility is caused by framework differences between FireMonkey (FMX) and VCL. My application is a pure VCL application that is built with runtime packages. All VCL forms are stored in a runtime package. If I am going to create a FireMonkey form and store in a package, do I have

Previous posting/answer The objective is to change the cell attributes (Font, style, colour etc...) of the value I am about to return as the cell "Value". In the example below;

How to free a component in Android / iOS

The same seems to happen not only for TEdit but for any component using Android or iOS. Short Answer There are two rules that should be followed when releasing any TComponent descendant object under Delphi ARC compilers (currently Android and iOS): using DisposeOf is mandatory regardless of object having owner or not in destructors or in cases where reference is not going out of scope shortly after
