I have an array of buttons:
class Window : MainWindow{
private Button[4] bArr;
this(){
Button btn_1 = new Button();
Button btn_2 = new Button();
Button btn_3 = new Button();
Button btn_4 = new Button();
Button[4] bArr = [btn_1,btn_2,btn_3,btn_4];
}
private void letButtonsFlash(){
for(int i = 0; i < 4; i++){
writeln(this.bArr[i].getName());
}
}
}
i don't understand why i get an 'Access Violation' - Error in
the 'for'-loop?
Okay, i solved it, instead of:
Button[4] bArr = [btn_1,btn_2,btn_3,btn_4];
this:
bArr = [btn_1,btn_2,btn_3,btn_4];
I would also suggest you use a foreach loop to iterate over the
buttons:
private void letButtonsFlash()
{
foreach(button; bArr)
{
writeln(button.getName());
}
}
//Also, question to anyone: should a ref be used here?
No, ref for classes is pointless. The ptr destination is always
the same heap chunk, whatever you use the original pointer or not.
