我需要Warning: This will result in...显示在新行和红色字体上。我在TLama's solution中找到InnoSetup: How to add line break into component description，但结果为List index out of bounds(0)，因为您可以看到，该任务会在我的脚本中有条件地显示。
答案 0 :(得分：2)
如果您尝试更新RIGHT JOIN中的TasksList，则必须获得例外，因为此时InitializeWizard尚未填充，无论任务是有条件的还是不
只有在您转到“选择其他任务”页面后才会填充TasksList。
因此，您只需在CurPageChanged(wpSelectTasks)中更新任务标题。在此之前测试not WizardIsComponentSelected('Slasher')（在Inno Setup 6.0.2之前TasksList）（有关详细信息，请参阅代码中的注释）。
IsComponentSelected我很确定无法改变某项特定任务的颜色。您所能做的就是为应该具有不同颜色的每组任务创建单独的procedure CurPageChanged(CurPageID: Integer);
begin
if CurPageID = wpSelectTasks then
begin
{ This has to be kept in sync with the expression in "Components" parameter }
{ of the respective task. Though note that in your specific case the test }
{ is redundant as when "Slasher" is selected, you have no tasks, }
{ and the "Tasks" page is completely skipped, so you do not even get here. }
{ Before Inno Setup 6.0.2, use IsComponentSelected. }
if not WizardIsComponentSelected('Slasher') then
begin
WizardForm.TasksList.ItemCaption[0] :=
'Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed id' + #13#10 +
'venenatis erat, ac vehicula sapien. Etiam convallis ligula eros,' + #13#10 +
'in ullamcorper turpis pulvinar sit amet.';
end;
end;
end;
（并使用其TNewCheckListBox属性设置颜色。）
如果您想了解更多详细信息，请提出单独的问题。换行符和颜色是两个不同的问题。
