<Page>.OpenChild (Función)
 No disponible
Opens a non-modal child window. <Page>.OpenChild is also used to: - define the display position of child window,
- pass parameters to the child window.
The following events are run when <Page>.OpenChild is called: - "Global declarations" of the child window,
- control initialization codes (undefined order),
- processes/events after the call to the <Page>.OpenChild function of the parent window,
- the child window is displayed.
Remark: By default, the child window retains focus once opened. // Open the child window named "WIN_EditWindow"
// without positioning and without passing parameters
WIN_EditWindow.OpenChild()
// Open the child window named "WIN_EditWindow".
// The value of the "EDT_EditCustomer" control is passed as parameter to the event
// "Global declarations" of "WIN_EditWindow".
WIN_EditWindow.OpenChild(EDT_EditCustomer)
// -- Event "Global declarations" of "WIN_EditWindow"
// Retrieve the parameters
PROCEDURE WIN_EditWindow(Customer)
Customer.ReadSeek(CustomerName, Customer)
IF Customer.Found() = True THEN
FileToScreen()
ELSE
Error("No customer matches")

<Window>.OpenChild([<Parameter 1> [... [, <Parameter N>]]])
<Window>: Nombre de ventana - Name of child window to open.
- Name and full path of child window (".WDW" file) to open.
<Parameter 1>: Tipo de valor enviado a la ventana (opcional) First parameter that will be passed to the "Global declarations" event of the window to open. This parameter is passed by value and is considered a variable global to the window.
This parameter cannot be a variable of type array (arrays can only be passed by reference). <Parameter N>: Tipo de valor enviado a la ventana (opcional) Nth parameter that must be passed to the "Global declarations" event of the window to open. This parameter is passed by value and is considered a variable global to the window.
This parameter cannot be a variable of type array (arrays can only be passed by reference). Observaciones Parameters passed to the child window to open The parameters are retrieved in the "Global declarations" event of the window. Simply write the following line of code at the start: PROCEDURE <Window name> (<Parameter1> [, <Parameter2> [, ...]]) These parameters are passed by value, not by reference.
Window opening mode The window is opened in non-modal mode: - the child window becomes the current window.
- once the child window is opened, the processes following the call to <Page>.OpenChild in the parent window are run.
- the user will have the ability to click one of the parent windows of opened window.
Position of parent window The parent window always remains below the child window, even if the parent window is in edit. If this situation is not suitable, the child window must be opened by OpenSister (providing that the parent window is a non-modal window). Limitation <Page>.OpenChild must not be called in the project initialization code.
Closing a window A window opened with <Page>.OpenChild can be closed with Close (without parameters) from any event: - of the window,
- of a window control.
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 the window of a component To open the window of a component, simply use the name of the component window (component included in the project). For example: OpenChild(ComponentWindow)
If a conflict occurs with a project element, the element name must be prefixed by the component name. For example: OpenChild(MyComponent.Window)
To use the name of the window in a variable, the name of the component must be specified. For example: sWindow is string ="MyComponent.MyWindow"
OpenChild(sWindow)
