Report on Looper control
Overview
The report on Looper control is used to directly print the information displayed in a Looper control (browsing looper, memory looper or looper on source) found:
  • in a window or page of application. This window or page must be displayed when printing the report.
  • in an internal window or an internal page. The window (or the page) that displays the internal window (or the internal page) must be displayed.

Important

Reports & Queries cannot be used to create reports on Looper control. However, you have the ability to customize the reports on Looper control created in the standard report editor (color, fonts, size, ...).
A report on Looper control can print:
  • all rows displayed in the Looper control.
  • the rows selected by the user (for multiselection Looper controls where the rows are selected with the Ctrl key). This option is not available in WEBDEV.
Characteristics of report on Looper control
If the report is based on a Looper control:
  • Each row found in the Looper control corresponds to a record.
  • Each attribute of Looper control corresponds to a Static control (even the attributes that do not correspond to a value).
For a table report, the order in which the columns are displayed in the report corresponds by default to the order of attributes in the window currently edited.
A report on Looper control can be created:
  • from the window editor. The created report corresponds to a table report.
  • from the report editor. The wizard for report creation starts and it allows you to choose the type of report to create (table, form, ...).
Once the report on Looper control is created, you can:
  • modify the data source of report ("Data" tab of report description).
  • add or delete Static controls linked to the Looper control associated with the report.
Caution: The test of a report on Looper control cannot be run from the report editor because the window or the page containing the Looper control must be opened. To run the test of a report on Looper control, you must:
  • create (if necessary) a button in the window or in the page of Looper control. This button is used to print the report on Looper control (iPrintReport).
    Case of internal windows: If the Looper control is found in an internal window, the button should be created in the internal window (and not in the host window).
  • run the test of the window containing the Looper control then run the report test (via the button).
    Case of internal windows: the test must be run from the window that is hosting the internal window.
Creating a report on Looper control from the window editor
Creating a report on Looper control from the report editor
The report editor allows you to create any type of report based on a Looper control (table, form, ...).
Once the report is created, the print must be programmed in WLanguage. See Printing a report on Looper control for more details.

Creating a report on Looper control from the report editor

To create a report on Looper control from the report editor:
  1. Click New among the quick access buttons.
    • The element creation window appears: click "Report" then "Report". }
    • The report creation wizard starts.
  2. Choose the layout of your report (table, form, label, ...). See The different types of reports for more details.
  3. Select (if necessary) the report template to use. A report template is used to comply with a specific page layout. See The report templates for more details.
  4. Select the data source of report ("From a Table or Looper control").
  5. Select the Looper control on which the report will be based. Only the Table and Looper controls found in the windows or in the pages of current project are proposed.
  6. For each attribute of the Looper control displayed in the report:
    • specify whether the column must be printed or not via the checkmark.
    • type the corresponding caption. This caption will be displayed:
      • before the control. For example:
        =Caption before the control
      • in the column header (for the Table reports). For example:
        Caption in the columns

        This caption can be modified in the report editor.
    • select the block where the control associated with the attribute of Looper control will be printed. The positions of different controls can be modified in the report editor. See Report blocks for more details.
  7. Modify (if necessary) the display order of controls in the report with the arrow buttons found on the right of table.
  8. If the Looper control associated with the report contains at least one numeric item, calculations can be performed on these items. Specify the calculation performed for each item (sum, average, ...). Two types of calculations are available:
    • general calculation: a Calculated control will be created in the End of document block.
    • calculation on break: a Calculated control will be created in the Break footer block. In the calculations on break, the calculation result is re-initialized after each break. To perform a calculation on break, a break must be found in the report currently created.
  9. Depending on the type of report currently created, indicate the specific options.
    Type of reportSpecific options
    Report on formForm image, printing the form image, ...
    Options presented in Report on form
    Label reportFormat of labels, number of identical copies, ...
    Options presented in Label report
  10. Specify the format of sheet on which the report will be printed. The report is printed in A4 format by default.
    Remark: By default, the report controls are displayed in a single column. To create a multi-column report, the requested number of columns must be specified in the "Format" tab of the description window of report.
  11. Select the skin template of report if necessary.
  12. Type the name and title of report (name of ".WDE" file corresponding to the report). This name will be used to identify the report in your programs.
  13. Validate the report creation.
  14. The report editor automatically proposes to change the report format if the following conditions are fulfilled:
    • the report currently created includes a table.
    • the report format does not allow to display all table columns.
  15. Specify (if necessary) the mode for reducing the report size:
    • Print the report on several pages. In this case, the end user will have to group the pages. See Multi-page print for more details.
    • Use the landscape mode.
    • Reduce the report size. Caution: according to the reduction percentage, the printed report may become unreadable.
  16. The report currently created is displayed in the report editor.
Printing a report on Looper control

Printing a report on Looper control

A report on Looper control must be printed from the window displaying the Looper control to print. If the button was not created automatically, you must:
  1. Create a button in the window (or page) containing the Looper control.
  2. Configure the report print destination:
  3. Specify the name of report to print with iPrintReport.
Remarks:
  • If additional parameters must be passed to the report, these parameters must be specified in iPrintReport, after the name of report to print. See Report with parameters for more details.

Important

In Reports & Queries, a report can be printed:
  • by starting a print ( Print icon ).
  • by running the report test ( Report Go ).
Therefore, no programming is required to print the report.
WEBDEV - Server code

WEBDEV example

The information to print is in the Looper control named "LOOP_Customer" found in the "PAGE_Customer" page.
The report to print is named "RPT_LOOPCustomer" and it is displayed in a PDF file when clicking the "BTN_Print" button.
In this example, the click code of "BTN_Print" button is as follows:
// Generates a unique file name
UniqueFileName is string = fWebDir() + "\" + ...
"RPT_Customer_" + DateSys() + TimeSys() + ".pdf"
// Configures the print destination
iDestination(iPDF, UniqueFileName)
// Prints the report based on the "LOOP_Customer" control
iPrintReport(RPT_LOOPCustomer)
// Displays the report in PDF format
FileDisplay(UniqueFileName, "application/pdf")
// Deletes the file
fDelete(UniqueFileName)
Minimum version required
  • Version 22
