控件style你知我知
2006-02-04 13:55:22 来源:WEB开发网一般控件我可以通过给于我们的属性设置,但我们不可能满足这些属性
比如我们要edit1.text只能是数字,虽然我可以在edit.change监控,但
其控件style已提供相应的style,下面是代码----还有一些style自己
试一下。
var
defstyle: dWord;
begin
defstyle := GetWindowLong(Edit1.Handle, GWL_STYLE);
SetWindowLong(Edit1.Handle, GWL_STYLE, defstyle or ES_NUMBER)
end;
