需要个类似资源管理器的东西, 首先试了下 TDriveComboBox、TDirectoryListBox、TFileListBox, 嘿! Win31 时代的东西, 不是一般地丑.

试了下 Vcl.Shell.ShellCtrls 下的 TShellComboBox、TShellTreeView、TShellListView, 非常满意! 并且 TShellComboBox 也可以免掉了.


unit Unit1;

interface

uses
Winapi.Windows, Winapi.Messages, System.SysUtils, System.Variants, System.Classes, Vcl.Graphics,
Vcl.Controls, Vcl.Forms, Vcl.Dialogs, Vcl.FileCtrl, Vcl.StdCtrls,
Vcl.ComCtrls; type
TForm1 = class(TForm)
procedure FormCreate(Sender: TObject);
private
procedure TreeViewOnChange(Sender: TObject; Node: TTreeNode);
public
end; var
Form1: TForm1; implementation {$R *.dfm} uses Vcl.Shell.ShellCtrls; var
C: TShellComboBox;
T: TShellTreeView;
L: TShellListView; procedure TForm1.FormCreate(Sender: TObject);
begin
C := TShellComboBox.Create(Self);
T := TShellTreeView.Create(Self);
L := TShellListView.Create(Self); C.Parent := Self;
T.Parent := Self;
L.Parent := Self;
T.Width := Screen.Width div 4; C.Align := alTop;
T.Align := alLeft;
L.Align := alClient; T.ShellComboBox := C;
L.ShellTreeView := T; L.ViewStyle := vsList; T.OnChange := TreeViewOnChange;
end; procedure TForm1.TreeViewOnChange(Sender: TObject; Node: TTreeNode);
begin
Caption := T.SelectedFolder.PathName;
end; end.
