delphivcl.CreateComponent is a function to create a specified component.
We call CreateComponent to create an instance of ComponentClass at the position specified by the Left and Top parameters with the size specified by the Width and Height parameters. The new component will be a child of the component specified by the Parent parameter.
We can browse all the properties, methods, and built-in properties of the delphivcl.CreateComponent using dir() command:
|
1 2 3 |
import delphivcl dir(delphivcl.CreateComponent) |
See the responses in command prompt:
Here is the working example of the implementation of delphivcl.CreateComponent to create a Main Panel inside your (previously created) basic form:
|
1 2 3 |
# Create a Main Panel component pnlMain = CreateComponent('TPanel',Owner) pnlMain.SetProps(Parent=self, Caption="",align = "alClient", Name = "MainPanel") |
Run the complete script, to get the following result:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 |
from delphivcl import * # Create a Class to build a basic Form class MainForm(Form): def __init__(self, Owner): self.Caption = "Introduction to VCL Components" self.Name = "BaseForm" self.SetBounds(10, 10, 700, 650) # Create a Main Panel component pnlMain = CreateComponent('TPanel',Owner) pnlMain.SetProps(Parent=self, Caption="",align = "alClient", Name = "MainPanel") # Initialize your application def main(): Application.Initialize() Application.Title = "MyDelphiApp" f = MainForm(Application) f.Show() FreeConsole() Application.Run() Application.Destroy() main() |
The result:
We will talk more about the Main Panel or TPanel in the next Section.

Note for beta release users
In practice, the only difference between DelphiVCL for Python release version and the beta version is only in how you write the DelphiVCL. Here is the example for how you import the library:
- Release version:
|
1 |
from delphivcl import * |
- Beta version:
|
1 |
from DelphiVCL import * |
