问题描述

是否可以在选择其他任务页面上拆分任务列表，如下图所示?

Is it possible splitting tasklist at Select Additional Tasks page like in the picture below?

示例:

谢谢.

推荐答案

否，Inno安装程序不支持多列(选中)列表框.

No, Inno Setup does not support multi-column (check) list boxes.

但是您可以轻松实现具有标准选择其他任务" 页面的外观的自定义页面，只需三个单独的复选框即可.然后，您可以使用 Check参数代替 Tasks参数将自定义任务绑定到诸如Files，Icons，等

But you can easily implement a custom page with look and feel of the standard "Select Additional Tasks" page, just with three separate check list boxes. Then, you can use the Check parameter instead of the Tasks parameter to bind custom tasks to sections likes Files, Icons, etc.

Source: "FileForSubTask_0_1.txt"; DestDir: "{app}"; Check: GetCustomTask(0, 1);
Source: "FileForSubTask_0_2.txt"; DestDir: "{app}"; Check: GetCustomTask(0, 2);

var
  CustomSelectTasksPage: TWizardPage;
  TasksLists: array of TNewCheckListBox;

const
  TaskColumns = 3;

procedure InitializeWizard();
var
  TasksList: TNewCheckListBox;
  I, GapWidth: Integer;
begin
  CustomSelectTasksPage :=
    CreateCustomPage(
      wpSelectTasks, SetupMessage(msgWizardSelectTasks),
      SetupMessage(msgSelectTasksDesc));

  SetArrayLength(TasksLists, TaskColumns);

  GapWidth := ScaleX(16);

  for I := 0 to TaskColumns - 1 do
  begin
    TasksList := TNewCheckListBox.Create(WizardForm);
    TasksList.Width :=
      (CustomSelectTasksPage.SurfaceWidth - (GapWidth * (TaskColumns - 1))) div
        TaskColumns; 
    TasksList.Left := I * (TasksList.Width + GapWidth);
    TasksList.Top := 0;
    TasksList.Height := WizardForm.InnerNotebook.Height - ScaleY(8);

    TasksList.BorderStyle := bsNone;
    TasksList.Color := clBtnFace;
    TasksList.ShowLines := False;
    TasksList.MinItemHeight := ScaleY(22);
    TasksList.ParentColor := True;
    TasksList.WantTabs := True;

    TasksList.Parent := CustomSelectTasksPage.Surface;

    TasksLists[I] := TasksList;
  end;

  TasksLists[0].AddCheckBox('TASK 0:0', '', 0, False, True, False, False, nil);
  TasksLists[0].AddCheckBox('Subtask 0:1', '', 1, False, True, False, False, nil);
  TasksLists[0].AddCheckBox('Subtask 0:2', '', 1, False, True, False, False, nil);

  TasksLists[1].AddCheckBox('TASK 1:0', '', 0, False, True, False, False, nil);
  TasksLists[1].AddCheckBox('Subtask 1:1', '', 1, False, True, False, False, nil);
  TasksLists[1].AddCheckBox('Subtask 1:2', '', 1, False, True, False, False, nil);

  TasksLists[2].AddCheckBox('TASK 2:0', '', 0, False, True, False, False, nil);
  TasksLists[2].AddCheckBox('Subtask 2:1', '', 1, False, True, False, False, nil);
  TasksLists[2].AddCheckBox('Subtask 2:2', '', 1, False, True, False, False, nil);
end;


function GetCustomTask(ListIndex: Integer; TaskIndex: Integer): Boolean;
begin 
  Result := TasksLists[ListIndex].Checked[TaskIndex];
end;
