Descrição

Note: This command only works with array type list boxes.

The LISTBOX Get row color command returns the color of a row or a cell in the list box designated by the object and * parameters.

Passing the optional * parameter indicates that the object parameter is an object name (string). If you do not pass this parameter, it indicates that the object parameter is a variable. In this case, you pass a variable reference instead of a string. You can designate a list box or a list box column in the object parameter:

When object designates a list box, the command returns the color of the row.
When object designates a list box column, the command returns the color of the cell.

In row, pass the number of the row whose color you want to get.

Note: The command does not take any hidden/shown states of the list box rows into account.

In the colorType parameter, you can pass either the Listbox background color or Listbox font color constant ("List Box" theme) in order to find out the background or font color for the row. If you omit this parameter, the font color is returned.

Warning: a color assigned to a row is not necessarily displayed in every cell of the row (see example). If conflicting color values are set using properties for list boxes or list box columns, an order of priority is applied. For more information, refer to the Design Reference manual.

 vColor:=LISTBOX Get row color(*;"Col5";3)

 vColor2:=LISTBOX Get row color(*;"List Box";3)

 vColor3:=LISTBOX Get row color(*;"List Box";Listbox background color)

  // vColor contains 0xFFFF00 (yellow)

  // vColor2 contains 0x00FF (blue)

  // vColor3 contains 0x00FF0000 (red)
