我已使用
在InnoSetup脚本的“其他任务”页面中添加了一个复选框[Tasks]
Name: "StartMenuEntry" ; Description: "Start my app when Windows starts" ; GroupDescription: "Windows Startup"; MinVersion: 4,4;
我想在wpSelectTasks
页面显示时初始化此复选框,并在单击Next
按钮时读取值。我无法弄清楚如何访问复选框`checked'值。
function NextButtonClick(CurPageID: Integer): Boolean;
var
SelectTasksPage : TWizardPage ;
StartupCheckbox : TCheckbox ;
begin
Result := true ;
case CurPageID of
wpSelectTasks :
begin
SelectTasksPage := PageFromID (wpSelectTasks) ;
StartupCheckbox := TCheckbox (SelectTasksPage... { <== what goes here??? }
StartupCheckboxState := StartupCheckbox.Checked ;
end ;
end ;
end ;

任务复选框实际上是WizardForm.TasksList
复选框列表框中的项目。如果你知道他们的索引,你可以很容易地访问它们。请注意,项目可以分组(只是你的情况),每个新组也在该检查列表框中也有一个项目,所以对于你的情况,项目索引将是1:
[Setup]
AppName=TasksList
AppVersion=1.0
DefaultDirName={pf}\TasksList
[Tasks]
Name: "TaskEntry"; Description: "Description"; GroupDescription: "Group";
[code]
function NextButtonClick(CurPageID: Integer): Boolean;
begin
Result := True;
if CurPageID = wpSelectTasks then
begin
if WizardForm.TasksList.Checked[1] then
MsgBox('First task has been checked.', mbInformation, MB_OK)
else
MsgBox('First task has NOT been checked.', mbInformation, MB_OK);
end;
end;
procedure CurPageChanged(CurPageID: Integer);
begin
if CurPageID = wpSelectTasks then
WizardForm.TasksList.Checked[1] := False;
end;
以下说明当您有两个具有不同组的任务时,WizardForm.TasksList
检查列表框的外观如何:
要按说明访问任务复选框,请尝试以下操作:
[Setup]
AppName=Task List
AppVersion=1.0
DefaultDirName={pf}\TasksList
[Tasks]
Name: "Task"; Description: "Task Description"; GroupDescription: "Group 1";
[code]
function NextButtonClick(CurPageID: Integer): Boolean;
var
Index: Integer;
begin
Result := True;
if CurPageID = wpSelectTasks then
begin
Index := WizardForm.TasksList.Items.IndexOf('Task Description');
if Index <> -1 then
begin
if WizardForm.TasksList.Checked[Index] then
MsgBox('First task has been checked.', mbInformation, MB_OK)
else
MsgBox('First task has NOT been checked.', mbInformation, MB_OK);
end;
end;
end;
procedure CurPageChanged(CurPageID: Integer);
var
Index: Integer;
begin
if CurPageID = wpSelectTasks then
begin
Index := WizardForm.TasksList.Items.IndexOf('Task Description');
if Index <> -1 then
WizardForm.TasksList.Checked[Index] := False;
end;
end;

上面的答案很棒。给了我我需要的东西。
我有一个案例,我有一堆辅助安装程序,我使用'checkonce'选项,但我希望重新检查文件夹是否丢失(例如用户手动清除安装文件夹) ,例如
[Tasks]
Name: "InstallPython" ; Description: "Install Python" ; Flags: checkedonce
Name: "InstallNPP" ; Description: "Install Notepad++" ; Flags: checkedonce
[Code]
procedure CurPageChanged(CurPageID: Integer);
var
ItemIx: Integer;
begin
if CurPageID = wpSelectTasks then begin
if not DirExists(ExpandConstant('{app}')) then begin
for ItemIx := 0 to (WizardForm.TasksList.Items.Count - 1) do
WizardForm.TasksList.Checked[ItemIx] := True;
end
end
end;
