Opacity (Property)

In french: Opacité

The Opacity property is used to get and define the opacity percentage for a window, or for controls in a window or page. This gives you the ability to make a window transparent (or a control found in a window or in a page).

Remarks:

This property can also be applied to a page control.
This property may not be supported by the former browsers (Internet Explorer 5.5 and earlier, ...).
For a Color variable, the opacity value is not included between 0 and 100 but between 0 and 255.

Example

// Make the window invisible little by little (fade out)
i is int
FOR i = 1 TO 100
WIN_EditWindow.Opacity = 100 - i
END
Close()
