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…
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 displaying a modeless dialog box that was created using the CreateDialog API function. Assigning the handle of the modeless…
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…
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 automatically calls the destructor if the object reference is not nil. Any object instantiated at run time that does not have…
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…
In this post, we’ll use the EndFunctionInvoke method or DelphiVCL.Application.EndFunctionInvoke to block the caller until the specified ASyncResult completes. Learning how to do it will allow you to easily build GUIs with Python Build Tools.
Returns the result from…
In this post, we’ll use the EnumAllWindowsOnActivateHint property or DelphiVCL.Application.EnumAllWindowsOnActivateHint is a Boolean variable used for hint displaying. Learning how to do it will allow you to easily create GUIs with Python Programming Software.
EnumAllWindowsOnActivateHint is used internally by VCL for hint displaying. Do not use it directly.
Let’s browse all the…
