[Frogface-general] Validation in frogface

[Declan M. <dec...@fr...>]

Hi Ganesh,

I've worked out how the validation works in Frogface. It's pretty 
straightfoward. There are two types. One type of validation is an input mask 
which you create when you design the form graphically in QT4 Designer. The 
other type is a QValidator that you set in the main form of the application - 
in our case that is DiveDashboard.cpp. I've been practicing using QValidators 
to help me do regular expression validation. Anyway, here is what will need 
to be done for the next phase of the project.

* Validate maxlength of Dive Centre in Dive Brief tab (
the file divedashboardwidget.ui will need to be opened in QT Designer and the 
maxLength property on the Dive Centre field set to something sensible like 30
characters

* Validate max depth to be a decimal value (to 1 decimal place) less than 
1000. I've just been working on this - it's nearly there - but you can enter 
numbers greater than 1000.0 which is incorrect. We'll have to make that 
regular expression work harder :-) It's around around line 360 in 
DiveDashboard.cpp. That's where the regex is defined. For more info, search 
for QRegExp in QT Assistant in order to help get more info on QT's regex's.
* Validate average depth to a decimal value (to 1 decimal place) less than 
1000. So basically, we must make it the validate the same way as max depth.

I don't think the Time In, Time Out and Surf Int fields are saving correctly 
so I'll look at that next. Would you like to look at this validation issue 
above? As ever there's no rush either way :-) I wonder will we have anything 
for the QT4 competition :-) :-) :-)

All the best,
Dec
