Variable row content
The Looper controls allow you to customize the appearance of rows: layout, content, ...

Implementation

To create a Looper control with variable content:
  1. Creating a memory Looper control (filled by programming). This control must be a vertical Looper control containing a single column.
  2. Display the Looper control description window.
  3. In the "Content" tab of control description:
    • Check "Use an internal window per row".
    • Indicate the mode for unloading the internal windows:
      • Never: The internal windows are loaded when the associated row is visible in the control. The unload is never performed when using the control. It is performed when closing the window. This mode is recommended if there are few internal windows and if they do not contain too many controls .
        Benefit: The entire data is always available
        Drawback: Large memory consumption.
      • When the row is no longer visible (option selected by default): The internal windows are loaded when the associated row is visible in the control. The unload is performed when the row is not visible anymore. This mode is recommended for the non-editable Looper controls. Indeed, if an internal window allows the input, the content typed by the user is lost when this internal window is no longer visible.
        Benefit: Consumes few memory.
        Drawback: Loss of information typed by the user.
      • Row not visible + IW containing read-only controls: The internal windows are loaded when the associated row is visible in the control. The unload is performed according to the type of row:
        • If the row contains no control allowing the user input, the associated internal window is unloaded when it is no longer visible.
        • If the row allows the input, the associated internal window is never unloaded.
  4. Validate the description window of control.
  5. Create the different internal windows corresponding to the rows of Looper control.

    Modifies a row corresponding to an internal window in a memory Looper control.

Characteristics of internal windows

The characteristics regarding the width and height of internal windows are as follows:
  • Height: The height of the row using an internal window exactly corresponds to the height of internal window defined in edit. The height of internal window cannot exceed the height of Looper control.
  • Width:
    • If the width of internal window is smaller than the width of Looper control, the width of internal window is automatically increased and anchors are applied.
    • If the width of internal window exceeds the width of Looper control, the internal window is automatically truncated.
    In most cases, we advise you to create the internal window with the smallest possible width and to use anchors.
Note: If the internal window includes controls adapted to content, the row height will be increased or reduced according to the content.

The unload is performed when the row is not visible anymore. This mode is recommended for the non-editable Looper controls. Indeed, if an internal window allows the input, the content typed by the user is lost when this internal window is no longer visible.
        Benefit: Consumes few memory.
        Drawback: Loss of information typed by the user.
      • Row not visible + IW containing read-only controls: The internal windows are loaded when the associated row is visible in the control. The unload is performed according to the type of row:
        • If the row contains no control allowing the user input, the associated internal window is unloaded when it is no longer visible.
        • If the row allows the input, the associated internal window is never unloaded.
  4. Validate the description window of control.
  5. Create the different internal windows corresponding to the rows of Looper control.
  6. Add the internal windows into the Looper control via the following functions:
    Versions 23 and later
    LooperAddIW
    New in version 23
    LooperAddIW
    LooperAddIW
    Adds a row corresponding to an internal window at the end of a memory Looper control.
    Versions 23 and later
    LooperInsertIW
    New in version 23
    LooperInsertIW
    LooperInsertIW
    Inserts a row corresponding to an internal window into a memory Looper control.
    Versions 23 and later
    LooperModifyIW
    New in version 23
    LooperModifyIW
    LooperModifyIW
    Modifies a row corresponding to an internal window in a memory Looper control.

Characteristics of internal windows

The characteristics regarding the width and height of internal windows are as follows:
  • Height: The height of the row using an internal window exactly corresponds to the height of internal window defined in edit. The height of internal window cannot exceed the height of Looper control.
  • Width:
    • If the width of internal window is smaller than the width of Looper control, the width of internal window is automatically increased and anchors are applied.
    • If the width of internal window exceeds the width of Looper control, the internal window is automatically truncated.
    In most cases, we advise you to create the internal window with the smallest possible width and to use anchors.
Note: If the internal window includes controls adapted to content, the row height will be increased or reduced according to the content.
