Specifies the width of the column.
property Width: TWidth;
__property TWidth Width;
The Width property determines the default width of the column, in pixels. List columns can be resized at runtime by dragging their borders.
C++ Examples:
/* This example shows how to use the OnColumnClick and OnCompare events of a list view to let users sort the columns in a report-style list view by clicking on the column headers. This requires a global variable to keep track of the column that was clicked. The OnColumnClick event handler sets the global variable to indicate the column to sort and calls AlphaSort: */ void __fastcall TForm1::FormCreate(TObject *Sender) { TListItem *Item; TListColumn *Column; const char imagenames[3][20] = { "C++ Image", "Borland Image", "Delphi Image"}; const char Col2Array[3][40] = { "Documentation for the C++ icon.", "Borland icon.", "Delphi icon." }; // Create a ListView item for each image in the ImageList ListView1->SmallImages = ImageList1; ListView1->LargeImages = ImageList1; for (int i = 0; i < ImageList1->Count; i++) { Item = ListView1->Items->Add(); Item->Caption = imagenames[i]; Item->ImageIndex = i; Item->SubItems->Add(Col2Array[i]); } // Create two columns to show during viewing as vsReport Column = ListView1->Columns->Add(); Column->Caption = "Column 1"; Column->Width = 200; Column = ListView1->Columns->Add(); Column->Caption = "Column 2"; Column->Width = 200; ListView1->ViewStyle = vsReport; } int ColumnToSort = 0; /* The OnColumnClick event handler sets the global variable to indicate the column to sort and calls AlphaSort: */ void __fastcall TForm1::ListView1ColumnClick(TObject *Sender, TListColumn *Column) { ColumnToSort = Column->Index; dynamic_cast<TCustomListView *>(Sender)->AlphaSort(); } /* The OnCompare event handler causes the list view to sort on the selected column: */ void __fastcall TForm1::ListView1Compare(TObject *Sender, TListItem *Item1, TListItem *Item2, int Data, int &Compare) { if (ColumnToSort == 0) Compare = CompareText(Item1->Caption,Item2->Caption); else { int ix = ColumnToSort - 1; Compare = CompareText(Item1->SubItems->Strings[ix], Item2->SubItems->Strings[ix]); } }
