Are you looking for Python development tools that can be used in bioinformatics and to create a graphical user interface (GUI)?
You can build scalable Bioinformatics systems easily by combining these 6 powerful Python libraries and Python4Delphi for the GUI building part. Python4Delphi (P4D) is a free tool that allows you to execute Python scripts, create new Python modules and types in…
In this post, you’ll learn more about HintMouseMessage or DelphiVCL.Application.HintMouseMessage method regulates the display of hint windows. This method is called automatically when the mouse passes over control with a Hint. Applications rarely, if ever, call…
In this post, you’ll learn more about FreeOnRelease method or DelphiVCL.Application.FreeOnRelease is used to free the interface reference for components that were created from COM classes. FreeOnRelease is called when an interface implemented by the component is…
In this post, you’ll learn how to use the FreeNotification method or DelphiVCL.Application.FreeNotification to ensure that AComponent is notified that the component is going to be destroyed.
Use FreeNotification to register AComponent as a component that should be notified when the component is about to be destroyed. It is only necessary to register components this way when they are in a…
In this post, you’ll learn more about the GetInterface method or DelphiVCL.Application.GetInterface is used to retrieve a specified interface. GetInterface retrieves the interface designated by a GUID or type name. The basic implementation of GetInterface uses the GUID…
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…
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 is stored.
Notes:
GetHashCode is supposed to be overridden in user-derived classes, to provide consumer objects with…

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…
