範例
下列程式碼範例示範如何初始化 ListView 控制項。 此範例會 ColumnHeader 建立 物件,並設定資料行標頭的 Text 、 TextAlign 和 Width 屬性。 此範例也會將專案和子專案加入至 ListView 。 若要執行此範例,請將下列程式碼貼到表單中,並從表單的建構函式或 Load 事件處理常式呼叫 PopulateListView
方法。
private:
void PopulateListView()
{
ListView1->Width = 270;
ListView1->Location = System::Drawing::Point( 10, 10 );
// Declare and construct the ColumnHeader objects.
ColumnHeader^ header1;
ColumnHeader^ header2;
header1 = gcnew ColumnHeader;
header2 = gcnew ColumnHeader;
// Set the text, alignment and width for each column header.
header1->Text = "File name";
header1->TextAlign = HorizontalAlignment::Left;
header1->Width = 70;
header2->TextAlign = HorizontalAlignment::Left;
header2->Text = "Location";
header2->Width = 200;
// Add the headers to the ListView control.
ListView1->Columns->Add( header1 );
ListView1->Columns->Add( header2 );
// Specify that each item appears on a separate line.
ListView1->View = View::Details;
// Populate the ListView.Items property.
// Set the directory to the sample picture directory.
