Description
delphivcl.Memo is a wrapper for a Windows multiline edit control.
We use Memo to put a standard Windows multiline edit control on a form. Multiline edit boxes allow the user to enter more than one line of text. They are appropriate for representing lengthy information.
Note: Under Windows, there may be a limit of 64k of text for this control.
Browse all the properties, methods, and built-in properties of the delphivcl.Memo using dir() command:

Code example
Here is the working example of the implementation of delphivcl.Memo:
|
1 2 3 4 |
# Memo memoEvent = Memo(pgOne) memoEvent.SetProps(Parent=pgOne) memoEvent.SetBounds(75,15,350,300) |
To see the result, let’s run the complete script:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 |
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, 500, 450) # Create a Main Panel component pnlMain = CreateComponent('TPanel',Owner) pnlMain.SetProps(Parent=self, Caption="",align = "alClient", Name = "MainPanel") # Page control creation pgConMain = PageControl(pnlMain) pgConMain.Name = "MyPageControl" pgConMain.Parent = pnlMain pgConMain.Align = "alClient" # Tabsheet one pgOne = TabSheet(pnlMain) pgOne.PageControl = pgConMain pgOne.Caption = "Tab 1" # Memo memoEvent = Memo(pgOne) memoEvent.SetProps(Parent=pgOne) memoEvent.SetBounds(75,15,350,300) # Initialize your application def main(): Application.Initialize() Application.Title = "MyDelphiApp" f = MainForm(Application) f.Show() FreeConsole() Application.Run() Application.Destroy() main() |

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 * |
