如何根据徽章标题使用case语句? 尝试过:
procedure TForm2.Button1Click(Sender: TObject);
begin
case AdvBadgeGlowButton1.Caption of
'Test' : showmessage('Test')
end;
'' : showmessage('Empty')
end;
但得到了:
[dcc32错误] Unit2.pas(29):需要E2001序数类型[dcc32错误]
Unit2.pas(30):E2010不兼容的类型:“整数”和“字符串”
答案 0 :(得分:0)
case
不能用于非ordinal types的值(通常是整数值)。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;
