- Title of the window to be opened
- Minimized window
- Opening a component window
In french: Ouvre
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).
Remark: The controls found in the previous window are disabled.
In Java, the modal windows appear in the taskbar.
- 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.
This function is available only to simplify the Webification of WINDEV projects. In a WEBDEV site, this function has the same behavior as PageDisplayDialog
// 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))
<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
- 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 can define the display position of the window. The window name is completed by the window display coordinates when opened. This parameter has the following format:
"<Window name>, <Y>, <X>"
- <Window name>: name (or name and full path) of window to open.
- <Y>: Y-coordinate (in pixels) of window (in relation to the upper-left corner of the screen or parent window).
- <X>: X-coordinate (in pixels) of window (in relation to the upper-left corner of the 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.
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.
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 the window to be opened
By default, the window title is the one defined in the editor.
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:
If a conflict occurs with a project element, the name of the element must be prefixed by the name of the component. For example:
To use the name of the window in a variable, specify the name of the component. For example:
sWindow is string = "MyComponent.MyWindow"
