Inno-setup：基于现有页面类型的自定义向导页面

Question

我决定在基于 inno-setup 的安装程序中创建自定义向导页面。但我不想从头开始创建它。我想采用 TInputDirWizardPage 并修改它，例如添加一个组合框。是否可以？怎么做呢？

Answer 1

我自己想出来了。所以我会回答我自己的问题。示例代码如下：

[Code]
const DB_PAGE_CAPTION='Select Application Database Folder';
  DB_PAGE_DESCRIPTION='Where should application database files be installed or where     your database files already are?';
  DB_PAGE_SUBCAPTION='In case of new installation select the folder in which Setup should install application database files, then click Next. Or select folder where previous version of application stored database files, then click Next';

var databasePage : TInputDirWizardPage;//this is predefined form declaration
    CheckListBox : TNewCheckListBox;  //this is new element i'm about to add to page

procedure createDatabaseWizardPage; //creating page
begin
databasePage :=CreateInputDirPage(wpSelectDir,
DB_PAGE_CAPTION,
DB_PAGE_DESCRIPTION,
DB_PAGE_SUBCAPTION,
False, '');
databasePage.Add('');

databasePage.buttons[0].Top:=databasePage.buttons[0].Top+ScaleY(70);//moving predefined 
databasePage.edits[0].Top:=databasePage.edits[0].Top+ScaleY(70);    //elements down.
databasePage.edits[0].Text:=ExpandConstant('{commonappdata}\my app');//default value

CheckListBox := TNewCheckListBox.Create(databasePage);//creating and modifying new checklistbox
CheckListBox.Top := 40 + ScaleY(8);
CheckListBox.Width := databasePage.SurfaceWidth;
CheckListBox.Height := ScaleY(50);
CheckListBox.BorderStyle := bsNone;
CheckListBox.ParentColor := True;
CheckListBox.MinItemHeight := WizardForm.TasksList.MinItemHeight;
CheckListBox.ShowLines := False;
CheckListBox.WantTabs := True;
CheckListBox.Parent := databasePage.Surface;//setting control's parent element
CheckListBox.AddRadioButton('New Installation', '', 0, True, True, nil);
CheckListBox.AddRadioButton('Update existing copy', '', 0, False, True, nil);
end;


procedure InitializeWizard;
begin
createDatabaseWizardPage(); 
end;

谢谢大家！ :-)
