Button array

[22255565]

Good Morning,
I'm starting using borland delphi 6.0 in my university, I had used Visual Basic, but delphi is similar.But I have a problem, in VB6 , if I copy and paste a button it creates a button array. for example button1(1) will be the name of the pasted object. But in delphi I cannot make the same, but I need to do that. If anyone Knows how to do that I will aprecciate the help.

Thanks

Why do you want a button array? What is your goal?

You can handle collections of components in two ways: iterate theough all the components on the form and test for TButtons; or make an explicit array in code (e.g. a TList of the buttons you want).

If these techniques interest you, reply and I will be more explicit.

Cheers

You cant as in VB make an array of button at design time, but u can at run time.

2 choices:

1- Place all your buttons on your form, (they wont be an array but each a single objet). In your code .. make an array of TButton
//var
// MyArray : array[0..4] of TButton;
then on the form create event write asign your form button to the array.
// MyArray[0]:=Button1;
// .....
// MyArray[4]:=Button5;
thats it

2- Dont put your button on your form
in your code make an array of Tbutton
//var
// MyArray : array[0..4] of TButton;
in form create event create the buttons
//for cpt=0 to 4 do
//{ Myarray[cpt]:=TButton.create(self)
/*self for current FORM because its a form event*/
//Myarray[cpt].parent:=self;
//Myarray[cpt].onclick:=MyOnClickCode;
/*here set other attribute (i.e top, left, caption..)*/
}
U just have to create the MyOnClickCode; function with the same parameter that onclick usualy use and thats it..

i know there is other way to do it.. but those r easy, efficient and fast to code..

A third approach: Put all the buttons on in the designer, in FormCreate put a routine that puts them into an array.
