Par2: Multiple files on multiple browse tabs using Name() 1998-08-31 -- Lew Strock Where MyFile uses GLO:MyFile for its Name() and you want to display
different physical files on each tab of a browse:
CODE SNIP for the tab changing files for browsing in a listbox
ThisWindow.TakeNewSelection
|
OF ?CurrentTab
! change to another file as directed by tabs
ACCESS:MyFile.Close
Case Choice(?CurrentTab)
Of 1 !Score
GLO:MyFile = 'C:\c1.dat'
Of 2 !Penalty
GLO:MyFile = 'C:\c2.dat'
Of 3 !Bonus
GLO:MyFile = 'C:\c3.dat'
Of 4 !Tie Breaker
GLO:MyFile = 'C:\c4.dat'
End
ACCESS:MyFile.Open
ACCESS:MyFile.UseFile
BRW1.ResetFromFile()
! End of "Control Event Handling"
END
This worked as expected. BUT, using Edit in Place ...
I found that after getting the tabs to switch files for the browser's listbox
there was another problem. All related to event driven design.
If a choice to insert or change a record was made, a mouseclick on a tab
other than the one related to the current file would give the "new" tab focus.
But, nothing else would happen.
So a "NEW' tab would appear as the active BUT showing the "OLD" listbox
records. Not good.
A "solution" was found.
CODE SNIP to get a browse engaged in insert or change
activity to focus entirely on a NEW tab selection
ThisWindow.TakeFieldEvent
|
CASE Field()
|
OF ?CurrentTab
|
CASE EVENT()
OF EVENT:TabChanging
ThisWindow.TakeNewSelection ! the TRICK
|
The trick gives to desired result. I don't know if it's the right solution though.
But, it works.
