Create a Specific Component using DelphiVCL.CreateComponent
By Muhammad Azizul Hakim April 27, 2021

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:

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:

# 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:

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.
