delphi AdvBadgeGlowButton1 标题用例
delphi use case on AdvBadgeGlowButton1 caption
如何根据徽章标题使用案例陈述?
尝试过:
procedure TForm2.Button1Click(Sender: TObject);
begin
case AdvBadgeGlowButton1.Caption of
'Test' : showmessage('Test')
end;
'' : showmessage('Empty')
end;
但我得到了:
[dcc32 Error] Unit2.pas(29): E2001 Ordinal type required [dcc32 Error]
Unit2.pas(30): E2010 Incompatible types: 'Integer' and 'string'
case
不能用于非 ordinal types 的值(通常为整数值),如错误消息所述。您需要改用 if..else
。
procedure TForm2.Button1Click(Sender: TObject);
begin
if AdvBadgeGlowButton1.Caption = 'Test' then
ShowMessage('Test')
else if AdvBadgeGlowButton1.Caption = '' then
ShowMessage('Empty')
else
ShowMessage('Got unknown caption ' + AdvBadgeGlowButton1.Caption);
end;
