Opens a non-modal child window. OpenChild is also used to: - define the display position of child window,
- pass parameters to the child window.
The following events are run when OpenChild is called: - "Global declarations" of the child window,
- control initialization codes (undefined order),
- processes/events after the call to the OpenChild function of the parent window,
- the child window is displayed.
Remark: By default, the child window keeps focus once it is opened.  Versions 24 and later New in version 24

Syntax
Open a daughter window Hide the details
OpenChild(<Window> [, <Parameter 1> [... [, <Parameter N>]]])
<Window>: String or window name - Name of child window to open.
- Name and full path of child window (".WDW" file) to open.
<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 value and is considered a variable global to the window.
This parameter cannot correspond to an array variable (arrays can only be passed by reference). <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 value and is considered a variable global to the window.
This parameter cannot correspond to an array variable (arrays can only be passed by reference).
Opening a child window while defining its position and its display level Hide the details
OpenChild(<Window name [ + <Level>]> [, <Parameter 1> [... [, <Parameter N>]]])
<Window name [ + <Level>]>: Character string + Integer constant Used to specify: - the window to open (<Window name>). This parameter can correspond to:
- Name of child window to open.
- Name and full path of child window (".WDW" file) to open.
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:
"[<Alias>] = <Nom de la fenêtre> [, <Y>, <X>]"
where:- <Alias>: alias of the window if the same window is opened several times.
- <Window name>: name of the child window to open.
- <Y>: vertical display coordinate (in pixels) of window (in relation to the top left corner of screen or parent window).
- <X>: horizontal display coordinates (in pixels) of window (in relation to the top left corner of screen or parent window).
Remarks: - The coordinates are ignored if the window is defined as centered in the editor. It is advisable to use the WinSize function to change the display position of a window.
- the window display level (<Level>):
| | | Above | Window opened above all its sibling windows. | | AboveAll | Window opened above all the other windows (including the windows of other applications).
|
If one of these constants is used, the name of the window must be enclosed in quotes.
Remark: If two windows are opened with the same constant (Above or AboveAll), the second window will be opened above the first one.
It is recommended to use the WinStatus function to change the display level of a window.
<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 value and is considered a variable global to the window.
This parameter cannot correspond to an array variable (arrays can only be passed by reference). <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 value and is considered a variable global to the window.
This parameter cannot correspond to an array variable (arrays can only be passed by reference). Remarks Parameters passed to the child 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:
PROCEDURE <Nom de la fenêtre> (<Paramètre1> [, <Paramètre2> [, ...]])
These parameters are passed by value and not by reference.Opening mode of window 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 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). Limitations - The OpenChild function must not be called in the initialization code of a project.
Closing a window A window opened with OpenChild can be closed with ferme (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 window to open 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:
OpenChild(FenêtreDuComposant)
If a conflict occurs with a project element, the element name must be prefixed by the component name. For example:
OpenChild(MonComposant.Fenêtre)
To use the name of the window in a variable, the name of the component must be specified. For example:
sFenêtre is string ="MonComposant.MaFenêtre"
OpenChild(sFenêtre)
