How to set focus to a window control?
Two methods can be used to set focus to a control: First method: using SetFocusAndReturnToUserInput or SetFocus SetFocusAndReturnToUserInput (or SetFocus) gives focus to the specified control and it allows you to go back in edit to the window without running the WLanguage code found after the call to the function. Code example:
IF EDT_CODE = "" THEN
SetFocusAndReturnToUserInput(EDT_CODE)
// Code not run
ELSE
SetFocusAndReturnToUserInput(EDT_HEADING)
// Code not run
END
// Code not run
Second method: using ScreenFirst ScreenFirst is used to store the control that will gain focus. The WLanguage code that follows the call to the function continues to run. This allows you to change the control on which you want to be positioned before going back in edit to the window. Code example:
// Depending on the result of processes 1 and 2
// the position is set at the end of the process on EDT_QTY or EDT_DISCOUNTCODE
// Run process part 1
...
IF nResPart1 = 0 THEN ScreenFirst(EDT_QTY)
...
// Run process part 2
...
IF bResPart2 = False THEN ScreenFirst(EDT_DISCOUNTCODE)
...
