Stored procedures
Opens a modal WINDEV window.
Open is also used to:
  • define the display position of window,
  • pass parameters to the window.
During the call to Open, the following actions are run:
  • the event "Global declarations" of the window is run,
  • the "Initializing" events of the controls in the window are run (the order is undefined),
  • the window "Initializing" event is run,
  • displaying the window (this window becomes the current window).
For more details on the events associated with a window, see Events associated with a window.
Remark: The controls found in the previous window are disabled.
Mobile platforms:
  • iOS and UWP: Open is not available. Use OpenMobileWindow instead.
  • Android: Using Open in Android is not recommended. We recommend that you use OpenMobileWindow. If it is necessary to process the value returned by the window, use the event "Closing a child window" of the calling window.

Example
// Open and reposition the "EditWindow" window
// The Value1 and Value2 parameters are passed to the event
// "Global declarations" of "EditWindow"
// ReturnedValue will retrieve the returned value
// when the "EditWindow" window is closed
ReturnedValue = Open("EditWindow, 10, 15", Value1, Value2)
// Open a window at given position by using variables
x, y are int
x = MouseXPos(mpScreen)
y = MouseYPos(mpScreen)
Open(StringBuild("WIN_Popup,%1,%2", y, x))
Syntax
<Result> = Open(<Window name> [, <Parameter 1> [... [, <Parameter N>]]])
<Result>: Type corresponding to the retrieved value (optional)
Value returned by the popup window when it is closed. This value is returned:
  • by the RETURN keyword in the "Closing" event associated with the window,
  • by the Close function,
  • by the ReturnedValue property used before closing the window.
<Window name>: String or window name
Corresponds to:
  • the name of the window to be opened.
  • the name and full path of the window (".WDW" file) to be opened.
By default, the window is displayed according to the position defined in the editor. You have the ability to define the display position of the window. The window name is completed by the display coordinates of window when it is opened. This parameter has the following format:
"<Window name>, <Y>, <X>"
where:
  • <Window name>: name (or name and full path) of window to open.
  • <Y>: Y-coordinate (in pixels) of window (in relation to the top left corner of screen or parent window).
  • <X>: X-coordinate (in pixels) of window (in relation to the top left corner of screen or parent window).
Remark: The coordinates are ignored if the window is defined as centered in the editor.
<Parameter 1>: Type of value sent to the window (optional)
First parameter that will be passed to the "Global declarations" event of the window to open. This parameter is passed by reference and it is considered as being a variable global to the window.
<Parameter N>: Type of value sent to the window (optional)
Nth parameter that must be passed to the "Global declarations" event of the window to open. This parameter is passed by reference and it is considered as being a variable global to the window.
Remarks

Parameters passed to the window to open

The parameters are retrieved in the event "Global declarations" of the window. Simply write the following line of code at the start of the event:
PROCEDURE <Window name>(<Parameter1> [, <Parameter2> [, ...]])

For more details, see Window with parameters.

Window opening mode

The window is opened in modal mode:
  • the result of Open will be known once the window is closed,
  • the user will not be able to click in one of the parent windows of the current window.
To manage modeless windows, use OpenChild or OpenSister.
To manage MDI, use MDIOpen.

Number of opened windows

The number of windows that can be opened simultaneously depends on the available memory.

Closing a window

A window opened with Open can be closed with Close (without parameters) from any event associated with the window or a control in the window.
If a parent window is closed, its child windows are also closed.

Title of window to open

By default, the window title is the one defined in the editor.
To modify the window title, use NextTitle or CurrentTitle.
Reports and QueriesWindows

Minimized window

If the current window is minimized, the entire project is minimized.
The displayed icon is:
  • the one of the current window if the current window has an icon,
  • the one of the current project if the current window has no icon.

Opening a component window

To open a component window, all you have to do is use the name of the component window (the component being included in the project). For example:
Open(ComponentWindow)
If a conflict occurs with a project element, the name of the element must be prefixed by the name of the component. For example:
Open(MyComponent.Window)
To use the name of the window in a variable, specify the name of the component. For example:
sWindow is string = "MyComponent.MyWindow"
Open(sWindow)
Component: wd270obj.dll
Minimum version required
  • Version 9
