In this post, you’ll learn how to use the GetInterfaceEntry method or DelphiVCL.Application.GetInterfaceEntry to return the entry for a specific interface implemented in a class. GetInterfaceEntry returns the class entry for the interface specified by the IID parameter.
Note:
In Delphi Code, IID can be an interface name. The compiler replaces this name with the actual GUID. COM…
In this post, you’ll learn how to use the GetHashCode method or DelphiVCL.Application.GetHashCode is used to return an integer containing the hash code. By default, calling GetHashCode on an object returns an integer representing the virtual address at which the object…
This section lists all routines and classes included in Delphi’s VCL, split by categories. You can use these lists to navigate according to your needs.
VCL CategoryUnit(s)Additional ControlsVcl.ActnColorMaps, Vcl.ActnCtrls, Vcl.ActnMan, Vcl.ActnMenus, Vcl.ActnPopup…
We can use the CreateHandle method or DelphiVCL.Application.CreateHandle to generate a main window for the application if it does not already have one.
Do not call CreateHandle directly. In EXEs, the application’s constructor calls CreateHandle. In DLLs, it does not.
CreateHandle encapsulates much of what traditional Windows programs write in WinMain. For example, CreateHandle…
In this post, we’ll use the Create method of the DelphiVCL.Application object, & DelphiVCL.Application.Create, to create a new VCL-based application.Do not call Create directly. Each GUI application automatically creates an instance of an application object.
In this post, we’ll use the DialogHandle property or DelphiVCL.Application.DialogHandle provides a mechanism for using non-VCL dialog boxes in an application. Learning how to do it will allow you to easily build GUIs with Python Program Maker.
Use DialogHandle when…
In this post, we’ll use the FieldAddress method or DelphiVCL.Application.FieldAddress to return the address of a published object field. Learning how to do it will allow you to easily build GUIs with Python Coding Software.
FieldAddress is used internally by the component streaming system to access a specified published field of an object. FieldAddress returns a pointer to the field…
In this post, we’ll use the FindComponent method or DelphiVCL.Application.FindComponent to indicate whether a given component is owned by the component. Learning how to do it will allow you to easily build GUIs with Python Windows GUI Builder.
FindComponent…
In this post, we’ll use the Free method or DelphiVCL.Application.Free to destroy an object and free its associated memory, if necessary. Learning how to do it will allow you to easily build GUIs with Python Development Tools.
Use Free to destroy an object. Free…
In this post, we’ll use the Equals method or DelphiVCL.Application.Equals to check whether the current instance and the Obj parameter are equal. The function has one Obj parameter of the TObject type. Learning how to do it will allow you to easily build GUIs with Python Build Tools.
By default, the Equals method shows whether the addresses corresponding to the current object and the Obj…
