When running dir() to DelphiVCL library or any DelphiVCL methods and properties in all previous sections, you might find many of Python’s built-in objects and properties. Previously, we already discussed about __doc__, __file__, __loader__, __name__, __package__,__spec__, __class__, __contains__, __delattr__, __dir__, __eq__, __format__, __ge__, __getattribute__, __getitem__, __gt__, __hash…
DelphiVCL.Point or TPoint is used to define a pixel location on-screen.
The TPoint type defines the integer type X and Y coordinates of a pixel location on-screen, with the origin in the upper-left corner. X and Y specify the horizontal and vertical coordinates of a…
DelphiVCL.Persistent or TPersistent is the ancestor for all objects that have assignment and streaming capabilities. TPersistent encapsulates the behavior common to all objects that can be assigned to other objects, and that can read and write their properties to and from a…
DelphiVCL.Label or TLabel is a non-windowed control that displays text on a form.
Use Label to add text that the user cannot edit on a form. This text can be used to label another control and can set focus to that control when the user types an accelerator key. The Caption property can be used to define an accelerator key to a label control.
Because Label is not a descendant of WinControl…

DelphiVCL.TabSheet is an individual page in a PageControl object.
We use TabSheet to represent a single page in tabbed page control. Tab sheets are typically referred to as pages. PageControl maintains an indexed array of its tab sheets in its Pages property. Users can…
DelphiVCL.PageControl is a set of pages used to make a multiple page dialog box.
We can use PageControl to create a multiple page dialog or tabbed notebook. PageControl displays multiple overlapping pages that are TabSheet objects (we will discuss TabSheet in another article).
The user selects a page by clicking the page’s tab that appears at the top of the control.
You…
delphivcl.Panel or TPanel implements a generic panel control.
We can use TPanel to put an empty panel on a form. Panels have properties for providing a beveled border around the control, as well as methods to help manage the placement of child controls embedded in the…
Specifies a page in a DelphiVCL.Notebook or TNotebook control.
The DelphiVCL.Page or TPage class implements a page in a TNotebook control.
Let’s browse all the properties, methods, and built-in properties of the DelphiVCL.Page using dir()…
DelphiVCL.Object or TObject is the ultimate ancestor of all objects and components.
DelphiVCL.Object encapsulates fundamental behavior common to objects by introducing methods that:
Create, maintain, and destroy instances of the object by allocating, initializing, and freeing required memory.
Respond when object instances are created or destroyed.
Return class-type and instance…
