Chapter12:BuildingFormswithXforms
OpenOffice.org2.0nowallowstocreateformsbasedontheopenW3CXFormsstandard.
WithXFormsitisveryeasytoimplementsimplelogicwithoutanyprogramming.
Thissimpleexampledescribescreationofaformsdocumentwhichcanbeusedtocreateand
collectdata­setsofapredefinedstructureinordertoexchangethisdatawithotherparties.
1. Usercreatesanewdocumentasshownabove.
2. Useraddsformcontrolsandlaysoutofthedocument.
3. Whenlayoutiscompleted,,theusercanstarttoworkonthepropertiesoftheindividual
formcontrols.Thefirststepisbindingthecontrolstotheirrespectivecounterpartsin
theinstancedata.
4. Asubmissioncontrolisaddedbytheuser.Normallytheinstancedataissavedtogether
withthedocumentortoalinkedinstance.Byusingasubmitbutton,theinstancedata
canbesenttoaserver,toanemailrecipientorbesavedtoafile.
5. Theusercannowswitchoffdesign­modeforuse.Wherethefinishedformistobe
sharedwithothers,theusershouldalsosettheformtoopeninusagemodebydefault.
