我在InnoSetup脚本的“Additional Tasks”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按钮时读取该值.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 ;
解决方法
任务复选框实际上是
WizardForm.TasksList
检查列表框中的项目.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.',MB_OK); end; end; procedure CurPageChanged(CurPageID: Integer); begin if CurPageID = wpSelectTasks then WizardForm.TasksList.Checked[1] := False; end;
下面说明了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.',MB_OK) else MsgBox('First task has NOT been checked.',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;
