Printing the content of a table (AAF)
By default, a Table field offers an automatic context menu enabling the user to perform a number of operations on the data displayed in the Table field.. One of the options in this context menu allows the user to print the contents of the Table control ("Print" option). Principle Several cases may occur: - If the developer has created a report on this Table control, the report is printed.
- If no report is linked to this Table control, the user can:
- directly print the content of a Table control.
- start "Reports & Queries" (if it is installed on the user computer).
Differences between run and test mode: In test mode, the "Print" option lets you print directly or create a table report. This report will automatically be linked to Table control and will be proposed by default to the user. Remarks: - The "Print" option in the Table control context menu requires the print libraries of the WINDEV framework.
- In the code, AAFDisable with the aafPrintReportOnTable constant, removes the "Print" option for the specified Table control.
Printing the report created by the developer If the developer has created a report based on the Table control, the "Print" option will directly print the report. No specific programming is required. Directly print the content of the Table control The content of a Table control can be directly printed in the following cases: - the developer has not created a report for the Table control.
- Reports and Queries is not installed on the user computer,
- the application cannot be used to start Reports and Queries.
The content of the Table control is directly displayed in the report viewer. If the Table control has too many rows (more than 10,000), it asks the user for confirmation (the print job can take quite long and be memory intensive). If necessary, the application: - proposes to print in landscape mode,
- informs that all the columns will not be printed on the same page. In this last case, the user has the ability to resize the columns. If no resizing is performed, the content of the Table control will be printed on several pages if necessary.
The print characteristics are as follows: - The print title corresponds to the title of the Table control. If no title was specified for the control, the text "Report on table (AAF)" is printed.
- The column titles are printed on each page.
- The printout respects the background colors used for the different cells in the Table field.
- The print job does not reflect the RTF attributes of the text in the Table control.
- Counters, totals, etc. defined for the Table field are not printed.. Only a row counter can be printed below the Table control. The caption corresponds to the caption defined for the counter in the window editor.
- Today's date is printed in the upper-right corner.
- The number of the current page and the total number of pages are printed in the lower-right corner.
- The horizontal merge of columns is kept, except in the following cases:
- merge with an invisible column
- merge of columns that "overlay" over 2 pages.
- Images in Table controls are printed only if their path is specified. Images in memos are not printed.
- The printout takes into account the writing direction specified with the TextDirection property in the window and/or in the Table field.
- Columns defined as non exportable and non printable will not be printed (VisibleInExportAndPrint property or "Export and print" option in the "General" tab of the column description window).
Printing from Reports and Queries Reports and Queries is automatically started. The report is automatically created in Reports and Queries. The user can format it according to his own requirements. All you have to do is save the report in order for this one to be linked to the table and to be printed. If the developer creates a specific report for the Table control in a forthcoming version, the report created by the user will be used at runtime. If "Reports & Queries" is not installed on the user computer, it can be installed automatically by the user. Characteristics of the created report: - The created report is a "Report based on Table" report.
- If the report is automatically created in "Reports & Queries", the merge of columns is ignored.
