<Window name>: Character string (with or without quotes)

Name of window to open.

<Parameter 1>: Type of value sent to the window (optional)

Remarks

Characteristics of the popup window

The window is automatically closed when it loses focus or during the call to Close. The current value is returned to the control that opened the popup window by one of the following methods:
- by RESULT used in the "Closing" event associated with the window,
- by Close,
- by ..ReturnedValue used before closing the window.
The style of 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 is running 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 "Global declarations" window event. The first code line of this event must correspond to the following line:

PROCEDURE <Window name> (<Parameter1> [, <Parameter2> [, ...]])

See Window with parameters for more details.

Limits

OpenPopup must be run from the code of a control.
The control from which OpenPopup is run must be visible.
A window that is not a modal window cannot be opened from a popup window. Open must be used to open a window. Opening a modal window from a popup window does not automatically close the popup window. In this case, you must process the return value of Open and you must use Close to close the popup window.
A popup window cannot be opened from a popup window.
