我的程式碼如下,
可是 Button 按下去,
只有出現
ListView1.Columns.Add;
ListView1.Columns.Add;
的效果, Listview 那邊會多兩格. 可是檔案名跟圖標都沒有列出來,
請問有人可以跑出他範例的樣子嗎?
謝謝.
unit Unit1; interface uses Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms, Dialogs, ImgList, ComCtrls, StdCtrls; type TForm1 = class(TForm) ListView1: TListView; ImageList1: TImageList; Button1: TButton; procedure Button1Click(Sender: TObject); private { Private declarations } public { Public declarations } end; var Form1: TForm1; implementation {$R *.dfm} uses ShellApi; procedure LV_InsertFiles(strPath: string; ListView: TListView; ImageList: TImageList); var i: Integer; Icon: TIcon; SearchRec: TSearchRec; ListItem: TListItem; FileInfo: SHFILEINFO; begin // Create a temporary TIcon Icon := TIcon.Create; ListView.Items.BeginUpdate; try // search for the first file i := FindFirst(strPath '*.*', faAnyFile, SearchRec); while i = 0 do begin with ListView do begin // On directories and volumes if ((SearchRec.Attr and FaDirectory <> FaDirectory) and (SearchRec.Attr and FaVolumeId <> FaVolumeID)) then begin ListItem := ListView.Items.Add; //Get The DisplayName SHGetFileInfo(PChar(strPath SearchRec.Name), 0, FileInfo, SizeOf(FileInfo), SHGFI_DISPLAYNAME); Listitem.Caption := FileInfo.szDisplayName; // Get The TypeName SHGetFileInfo(PChar(strPath SearchRec.Name), 0, FileInfo, SizeOf(FileInfo), SHGFI_TYPENAME); ListItem.SubItems.Add(FileInfo.szTypeName); //Get The Icon That Represents The File SHGetFileInfo(PChar(strPath SearchRec.Name), 0, FileInfo, SizeOf(FileInfo), SHGFI_ICON or SHGFI_SMALLICON); icon.Handle := FileInfo.hIcon; ListItem.ImageIndex := ImageList.AddIcon(Icon); // Destroy the Icon DestroyIcon(FileInfo.hIcon); end; end; i := FindNext(SearchRec); end; finally Icon.Free; ListView.Items.EndUpdate; end; end; procedure TForm1.Button1Click(Sender: TObject); begin // Assign a Imagelist to the ListView ListView1.SmallImages := ImageList1; // Show Listview in Report Style and add 2 Columns ListView1.ViewStyle := vsReport; ListView1.Columns.Add; ListView1.Columns.Add; LV_InsertFiles('c:\tmp', ListView1, ImageList1); end; end. |
