[libreoffice-users] Re: Issues with date fields in dialogues

Hi Robert,

What you say is of course all true. But it's not to do with database records (my original 
experiments were in fact on a spreadsheet), but the data as held in the dialog(ue).

Your method (thanks again) of copying a UNO Date into the field works fine, as does changing the 
text. But the underlying data seems to be in two places at once - never good design :)  - and what 
you read depends on how it was written.

I'm trying to work out if this is part of the design of dialogues, or an unwanted side-effect (i.e. 
a bug). And I'm looking for guidance as to whether I should put it into bugzilla and see what 
happens.

Best regards,

Peter

You could work with a view on the dialog and with the model. The view 
only shows, what you could see on the screen. Could be there is some 
content behind which will be saved if you press the SAVE-Button. The 
model has content, which could be saved. 

I don't know much about dialogs, in form-controls the text could be 
changed and nothing would be saved by the database, because the value 
of the control hasn't been saved. 

If I will change a date in a form I write down 
oDateField.BoundField.updateDate( unoDate ) 
and this changes both: The content I could see and the content behind 
for the database. It works as typing it in the field. 

Regards 

Robert
