如果您运行的辅助窗口执着,你可以做这样的事情:
在调用窗口:
/* In definitions */
DEFINE VARIABLE ghSecondWindow AS HANDLE NO-UNDO.
/* In a trigger */
RUN secondWindow.w PERSISTENT SET ghSecondWindow.
/* Whenever you want to shift focus */
RUN setFocus IN ghSecondWindow.
在 “SecondWindow”:
PROCEDURE setFocus:
/* Replace FILL-IN-1 with any widget that can gain focus */
APPLY "ENTRY" TO FILL-IN-1 IN FRAME {&FRAME-NAME}.
END PROCEDURE.
然而,如果你不运行持久性窗口,您仍然可以通过步行窗口小部件树,第一个当前窗口,然后第二个窗口(一旦您已经本地化它)来实现此目的。
快速和难看的代码放在调用窗口,无论你想焦点转移。这可能不适合您的需求,因此可能需要重写。此外错误检查是几乎不在这里,并与可能的永恒循环处理没有错误检查是不是真正的最佳实践:
DEFINE VARIABLE hWin AS HANDLE NO-UNDO.
DEFINE VARIABLE hWidget AS HANDLE NO-UNDO.
/* Get the first child (widget) of the session */
ASSIGN
hWin = SESSION:FIRST-CHILD.
/* Loop through all widgets in the session */
loop:
DO WHILE VALID-HANDLE(hWin):
/* We've identified the correct Window! */
IF hWin:TYPE = "WINDOW" AND hWin:TITLE = "Secondary Window" THEN DO:
/* ** Very Ugly** this could use better error checking etc! */
/* Get the second field-group of the window */
/* This will depend on your layout with different frames etc */
/* What we really have is WINDOW:DEFAULT-FRAME:FIELD-GROUP:FIELD-GROUP */
/* Field groups are really only present in the widget tree - they lack visual */
/* representation */
/* Read about field-groups in the online help! */
ASSIGN
hWidget = hWin:FIRST-CHILD:FIRST-CHILD:FIRST-CHILD.
/* Loop through all widgets of the field-group */
DO WHILE VALID-HANDLE(hWidget).
/* We've found the correct fill-in, give it focus */
IF hWidget:TYPE = "FILL-IN" AND hWidget:LABEL = "Fill 1" THEN DO:
APPLY "ENTRY" TO hWidget.
LEAVE loop.
END.
/* Next window of the correct window */
hWidget = hWidget:NEXT-SIBLING.
END.
END.
/* Next widget of the session */
hWin = hWin:NEXT-SIBLING.
END.
你也可以做的“widget树走”递归如果你喜欢它!
