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 panel.
You can also use panels to group controls together, similar to the way you can use a group box, but with a beveled border (or no border) rather than the group box outline. Panels are typically used for groups of controls within a single form. If you intend to use the same grouping in other forms, you may want to use a frame instead.
We can browse all the properties, methods, and built-in properties of the delphivcl.Panel using dir() command:
|
1 2 3 |
import delphivcl dir(delphivcl.Panel) |
See the responses in command prompt:
Here is the working example of the implementation of delphivcl.Panel 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:

Note for beta release users
In practice, the only difference between DelphiVCL4Python 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 * |
