Overview of the Looper control
A Looper control is used to repeat the controls found in a specific area. More precisely, a Looper control is a "container" control that is used to repeat several times all the controls (edit controls, static controls, combo boxes, ...) included in it.
The Looper control simplifies the display and the input of information.
Compared to the Table control, the Looper control presents richer interfaces as all types of controls can be repeated.
The information displayed in the Looper control can:
  • be defined by programming: this is referred to as memory Looper control.
  • come from a data file or from a query: this is referred to as browsing Looper control.
  • come from a WLanguage variable: this is referred to as Looper control on source.

Notes:
  • Versions 18 and later
    According to the platforms, the Looper controls can be displayed:
    • vertically (by default on all the platforms).
    • horizontally.
      In WEBDEV, this type of control corresponds to the Linear Looper controls.

    Creating a Looper control
    To create a Looper control:
    1. In the window or page editor, click (or select "Insert .. Control .. Looper").On the "Creation" pane, in the "Data" group:
      • WINDEV expand "Looper" and select "Looper (vertical)".
        Versions 18 and later
        WINDEVWindows Note: You can create a horizontal looper via "Horizontal looper".

    2. Click the position where the control will be created in the window or page. The wizard for creating a Looper control starts automatically.
    Notes:
    • Versions 20 and later
      WINDEV The dimensions of created control are optimized in order to occupy the available space at the specified position. If the control size does not suit you, press Ctrl + Z: the default control size will be restored.

    Creating a horizontal Looper control

    You also have the ability to create horizontal Looper controls. In this case, the control will include a horizontal scrollbar used to scroll the different rows.
    To create a horizontal Looper control:
    1. On the "Creation" pane, in the "Data" group, expand "Looper" and select "Horizontal looper".
    2. Click the position where the control will be created in the window or page. The wizard for creating a Looper control starts automatically.
    To display the control characteristics, select "Description" from the popup menu of control.

    Attributes of a Looper control
    WINDEVUniversal Windows 10 AppJava

    Attributes of a Looper control in WINDEV or WINDEV Mobile

    A Looper control includes controls that are repeated on each row.
    Versions 16 and later
    WINDEVWindows The content of the tables, charts, ... can differ in each row. See Display a different content on each row for more details.
    New in version 16
    WINDEVWindows The content of the tables, charts, ... can differ in each row. See Display a different content on each row for more details.
    WINDEVWindows The content of the tables, charts, ... can differ in each row. See Display a different content on each row for more details.
    To find out or modify the characteristic of a control (its value, its color, ...), all you have to do is handle this control by programming.
    Note: For compatibility with WEBDEV, you also have the ability to use the attributes. In this case, to find out or modify the characteristic of a control (its value, its color, ...), all you have to do is handle this control or the corresponding attribute by programming.
    Vocabulary
    To easily handle a Looper control, you must be familiar with the following vocabulary:
    NameDefinition
    AttributeAn attribute corresponds to the association between the control found in the looper and the property of this control that will be modified on each row.
    For each attribute, you must define:
    • the attribute name.
    • the name of the control in the looper.
    • the property of the control that will be modified on each row (value, color, etc.).
    WINDEV Reminder: The attributes are not mandatory.
    Browsing looperThe Looper control is based on a data file or on a query. A record found in the data file is displayed on each row. Two types of browsing Looper controls are available:
    • Browsing looper "Loaded in memory": The content of the looper is loaded in memory then it is displayed. The access to the different control elements is faster. This mode is reserved for the data files containing less than 100 000 records.
    • Browsing looper in "Direct access (no limit)": The Looper control displays the content of the data file or query directly. The current record corresponds to the selected element. Each move performed in the control involves an access to the linked data file. This mode is reserved for the data files containing more than 100 000 records.
    Memory looperThe Looper control is not based on a data file or on a query. The elements displayed in the control are defined by the developer (by programming).
    Looper on sourceThe Looper control is based on a variable (global to the project, to the window or to the page, class member, etc.).
    Notes

    Swapping a Table control and a Looper control

    WINDEV, WINDEV Mobile and WEBDEV allow you to automatically transform a Table control into a Looper control:
    1. Select the Table control to transform.
    2. Select "Control .. Swap .. Table to Looper".On the "Modification" pane, in the "Transformations" group, expand "Refactoring and swapping" and select "Table to Looper".

    Refactoring: creating a Looper control from the selected controls

    WINDEV, WINDEV Mobile and WEBDEV allow you to automatically create a Looper control from the controls currently selected:
    1. Select the requested controls.
    2. Select "Control .. Refactoring .. Create a looper from the selection".On the "Modification" pane, in the "Transformations" group, expand "Refactoring and swapping" and select "Create a looper from the selection".
