Update QSQLTableModel in QT C++ -
i created 1 dialog used bindvalues
in sql database, , can save every new record sucessfully. problem i've got dialog qsqltablemodel
shows information database. every time make new record must close program , run again see changes in showinformationdialog()
. know way such don't need close program update information in showinformationdialog()
?
you can use select()
method of qsqltablemodel
class repopulate model data database. bound views updated automatically. suggest connecting signal wherever update data in database (i.e. dialog updating sql database) custom slot in showinformationdialog()
calls select()
of qsqltablemodel
object. assume have qmainwindow
object parent of both dialogues best place establish connection.
also since showinformationdialog()
's model used viewing data consider using qsqlquerymodel
. if used setquery()
method should used instead of select()
otherwise (the connection of signal showinformationdialog()
's slot) same.
