Selezione con il mouse

Selezione con il mouse
Domanda sicuramente ...banale.
In una DataBrowser come quella dell'esempio cosa devo fare per poter scegliere il record evidenziato con il doppio click del mouse in alternativa alla scelta con il Default Button?
Grazie per i suggerimenti...

Re: Selezione con il mouse
Your Defaultbutton has the code to return the complete record?
Pseudocode:
GfBBrowser inherit Databrowser
Method MouseButtonDoubleclick(..)
Super: Method MouseButtonDoubleclick(..)
Self:Owner:yourButtonname
...

Hi Karl,
this is the code (ButtonOk is the default button) but when you double click nothing happens.
What did I forget?
Thank you!

Code: Select all
method MouseButtonDoubleClick(oMouseEvent) class ScegliSchBrowse
local nButtonID as int
nButtonID := IIf(oMouseEvent == NULL_OBJECT, 0, oMouseEvent:ButtonID)
super:MouseButtonDoubleClick(oMouseEvent)
//Put your changes here
self:Owner:ButtonOK() // Return choice code to the Owner
return nil

Re: Selezione con il mouse
Hi all!
Riprendo X# dopo alcuni mesi in cui ho fatto altro.
In una dataBrowse non riesco a selezionare un record usando DoubleClick.
Di seguito il mio codice, sia con ButtonDoubleClick() che con MouseButtonDoubleClick(), come di seguito.
Per capire meglio cosa sbaglio allego un piccolo AEF di esempio.
Grazie per ogni suggerimento: certamente c'è qualcosa che manca...

Hi Gian,
Unfortunately due to the way the VOSDK and the DataBrowser is designed, you need to trap this at the browser level, in a subclass. Create one like this:
and then in the Init() of your StdDataWindow add this just after the SUPER:Init() call, in order to tell it to create the databrowser using your new class:
then, you can define a method in the window to do what you want:

Code: Select all
CLASS ParentDataBrowser INHERIT DataBrowser
METHOD CellDoubleClick() CLASS ParentDataBrowser

Send(SELF:Owner,#SubFormCellDoubleClick)
END IF
RETURN NIL
Code: Select all
SUPER:Init(oParentWindow)
SELF:BrowserClass := #ParentDataBrowser

Re: Selezione con il mouse
Hi Chris,
thanks for your time!
In VO it works well; in XIDE it gives me this error: and this is the line of code that generates the error (line 54):
and this is the DoOpenFile() method
Thanks for the tips

Gian,
Add a constructor to the class
Robert
Add a constructor to the class
Code: Select all
CLASS ParentDataBrowser INHERIT DataBrowser
CONSTRUCTOR(oOwner, xID, oPoint, oDimension)
SUPER(oWin, xID, oPoint, oDimension)
RETURN
METHOD CellDoubleClick() CLASS ParentDataBrowser
IF IsMethod(SELF:Owner,#SubFormCellDoubleClick)
Send(SELF:Owner,#SubFormCellDoubleClick)
END IF
RETURN NIL

If you remove the line
then the browser opens?

Re: Selezione con il mouse
If I remove the line:
there is a new error:
"..description : No exported method 'SETSTANDARDSTYLE'
Subsystem : BASE
GenCode : EG_NOMETHOD No exported method"
at line:.
If I remove this line too, the browser opens but Double Click doesn't work...
