Events associated with internal windows
Warning: Do not confuse "Internal Window Field" and "Internal Window": the "Internal Window Field" is a type of field and the "Internal Window" is a type of window.. WINDEV and WINDEV Mobile manage the following events by default for the "Internal Window" controls:
| | | Event | Runtime condition |
|---|
| Selection by swipe | Internal window with browse by swipe. Run once the new internal window was displayed and loaded. | | After loading the internal window | Executed when the internal window is changed by ChangeSourceWindow. This event is run after the "Global declarations" and "Initialization" events of the new internal window. This event allows you, for example, to initialize controls or to restore values in the internal window. | | Before unloading the internal window | Executed when the internal window is changed by ChangeSourceWindow. This event is run before the closing event of the initial internal window. This event is used, for example, to save the values present in the internal window. |
WINDEV and WINDEV Mobile manage the following events by default for the Internal Windows: | | | Event | Runtime condition |
|---|
| Declaration of global variables | Declaration of variables global to the window. This is the first code run when opening the window.
This code is run before the declaration code of the global variables of the host window (window in which the internal window is included).
You can, for example, call a procedure of the internal window from the declaration code of global variables of the host window. | | End of initialization | Executed when window is opened.
The events are run in the following order:- Initializing the window controls
- Initializing the window
- Focus gain
| | Closing | Executed when closing the window.
Remark: Re-entering one of the Edit control fields in this code prevents the window from closing. | | Enables you to group together the code for updating the window's fields: field content, status (visible, grayed, etc.), label to be updated, etc. This event can receive parameters. Simply declare a procedure in the event. For example:
PROCEDURE AskForRefresh(RefreshType is boolean)
This event is started upon request by the following functions: When these functions are called, you can specify the value of the parameters expected by the event. | | Entry | Optional event:
Executed when the cursor enters in the Internal Window control. | | Exit | Optional event:
Executed when changing control (when going from the Internal Window control to another control of the window). | | Whenever modified | Run whenever the control content is modified | | Set the Value property | Executed each time the Value property is specified for the Internal Wndow (directly or with the Value property). This code is used to retrieve the parameters passed to the internal window for example. | | Get the Value property | Executed each time the Value property of the internal window is retrieved. This code allows the internal window to return a value to the window that hosts the Internal Window control. |
Overview Several optional events can be added.
To add an optional event: - Select the desired control.
- Display the code window of this control (F2 key).
- Click the link "Add other events to xxx" at the bottom of the window code, after the last event.
- All the optional events available for the control are displayed.
- Check the optional event to add and validate.
Note: Several optional events can be selected. - The selected optional event is automatically added to the events managed by the control.
To disable an optional event, simply perform the same operations to display the list of optional events. Then simply uncheck the optional events to delete.
Note: If the deactivated code contains WLanguage code, this code is automatically deleted.. For example, you can use the following events: - the mouse hover over the control,
- left mouse button down, up, double click,
- right mouse button down, up, double click,
- mouse wheel, etc.
Optional event: Start of dequeue Executed when the user starts scrolling an Internal Window control. This event is used to scroll through the content of the control, if necessary. Reminder: The ScrollbarPosition function is used to find out the position of the elevator. Note: This event is available both for the Internal window field and for internal windows.. Optional event: During dequeue Executed when the user scrolls an Internal Window control. This event is used to scroll through the content of the control, if necessary. Reminder: The ScrollbarPosition function is used to find out the position of the elevator. Note: This event is available both for the Internal window field and for internal windows.. Optional event: End of dequeue Executed when the user stops scrolling an Internal Window control. This event is used to scroll through the content of the control, if necessary. Reminder: The ScrollbarPosition function is used to find out the position of the elevator. Note: This event is available both for the Internal window field and for internal windows.. Optional event: Before skin template change Executed before the skin template is changed using function ChangeSkinTemplate.. Allows you to memorize certain style options for fields present in the internal window (for example, in the case of an internal window present in a component).. Note: This event is only available for internal windows.. Optional event: After skin template change Executed after the skin template has been changed using function ChangeSkinTemplate.. Enables you, for example, to reapply certain style options to fields present in the internal window (for example, in the case of an internal window present in a component)..
