<lekma> morning everyone
*** johannesV has joined #gnuenterprise
<johannesV> good morning
<lekma> johannesV: do you have tri-state checkboxes wxpython widgets?
*** yure has joined #gnuenterprise
<johannesV> lekma, yes
<johannesV> the checkbox-widget could be set up to have three states, true, false and 'not-set'
<lekma> how the 'not-set' state is visually rendered ?
<lekma> different background?
<johannesV> yes, i think so
<johannesV> on xp i think the box is gray
<johannesV> haven't checked though on all platforms here right now
<johannesV> i'm not sure if gnue-forms supports tri-state-checkboxes at all atm
<johannesV> but i'm sure we will with the 0.6 series
<johannesV> since we do have that third state (=NULL)
<johannesV> ah, well, that tri-state version of a checkbox is not available in wx.MGL, wx.Mac, and wx.GTK (if built against gtk1.2)
<lekma> johannesV since we do have that third state (=NULL) <-- what do you mean?
<johannesV> well, a boolean value might be null in the db
<lekma> you can't have a boolean = NULL in db, can you?
<lekma> !!!
<johannesV> so what state of a checkbox should then be displayed
<johannesV> false ?
<johannesV> oh, i think it depends on the db and wether it's set to a not null constraint
<johannesV> but with sqlite it's surely possible to have it set nullable
<lekma> so will gnue appserver support null boolean?
<lekma> cause it has impacts on building conditions
<johannesV> and postgres allows having nullable booleans  too
<johannesV> why should appserver care about that ? every property which is set as nullable could have a null state (=containing a python None)
<johannesV> or am i missing something now ?
<lekma> well for expressing a condition, if appserver supports null boolean i'll need a four state widget
<lekma> true, false, null and undefined
<johannesV> isn't null the same as undefined ?
<lekma> undefined being no condition
<lekma> undefined --> []
<lekma> null --> ["eq" , ["field", balbal], ["Cons", None/null/whatever]]
<johannesV> i would treat null and undefined the same (at least for booleans)
<johannesV> null --> ["isnull", ["field", blabal]]
<lekma> yes
<lekma> from th widget/usert pov you can't treat null and undefined the same
<lekma> if the widget as a "state == undefined" then there is no need to express a condition, return all true/false/null
<lekma> so i really need to know how appserver will support null boolean, but not right now :)
