Project: Console Application Runner Classes
Unit: PJConsoleApp
Classes: TPJCustomConsoleApp, TPJConsoleApp
Applies to: ~>3.0
property ScreenBufferSize: TSize;
Specifies the size of a console’s screen buffer in character columns and rows. If either dimension is zero or negative the default buffer size is used.
The property defaults to (0, 0).
If a console application shares a console this property has no effect. See UseNewConsole for more information about shared consoles.
The individual fields of the property are read-only so the property must be set by first creating a TSize record containing the required buffer size information and then assigning the record to the property. For example:
var
Size: TSize;
App: TPJConsoleApp;
begin
// assume App contains a valid TPJConsoleApp instance
Size.cx := 120; // 120 columns
Size.cy := 300; // 300 rows
App.ScreenBufferSize := Size;
end;
The MakeSize routine has been provided to make this process easier. The following code has the same effect as the above:
var
App: TPJConsoleApp;
begin
// assume App contains a valid TPJConsoleApp instance
App.ScreenBufferSize := MakeSize(120, 300);
end;
The property is public in TPJConsoleApp and protected in TPJCustomConsoleApp.
