After you build the DataWindow object and fill in print specifications, you can place it in a DataWindow control on a window or form, as described in “Putting a DataWindow object into a control”.
To allow users to print the report, your application needs code that performs the printing logic. For example, you can place a button on the window or form, then write code that is run when the user clicks the button.
To print the contents of a single DataWindow control or DataStore, call the Print method. For example, this PowerBuilder statement prints the report in the DataWindow control dw_Sales:
dw_Sales.Print(TRUE)
For information about the Print method, see the DataWindow Reference. For information about using nested reports to print multiple DataWindows, see “Using nested reports”.
For PowerBuilder applications only If the window has multiple DataWindow controls, you can use multiple PrintDataWindow method calls in a script to print the contents of all the DataWindow controls in one print job.
These statements print the contents of three DataWindow controls in a single print job:
int job
job = PrintOpen("Employee Reports")
// Each DataWindow starts printing on a new page.
PrintDataWindow(job, dw_EmpHeader)
PrintDataWindow(job, dw_EmpDetail)
PrintDataWindow(job, dw_EmpDptSum)
PrintClose(job)
For information about PowerBuilder system functions for printing, see the PowerScript Reference.
