- by the Close function,
- by the ReturnedValue property used before closing the window.
- The style of the popup windows is applied to the window opened by OpenPopup. If a title bar was defined in the editor, this title bar is reduced and the window cannot be maximized or minimized.
- The popup window is opened below the control that calls OpenPopup. If there is not enough space to open the window, the window will be opened either above the control, or below the control to the left.
Parameters passed to the window to open The parameters are retrieved in the event "Global declarations" of the window. The first line of code of this event must correspond to the following line:
PROCEDURE <Window name> (<Parameter1> [, <Parameter2> [, ...]])
Limitations - OpenPopup must be executed from the code of a control.
