Member Function Documentation

tristate KexiQueryView::afterSwitchFrom ( int mode ) [protected, virtual]

called by KexiDialogBase::switchToViewMode() right after dialog is switched to new mode By default does nothing. Reimplement this if you need to do something after switching to this view.
Returns:
true if you accept or false if a error occupied and view shouldn't change If there is no error but switching should be just cancelled (probably after showing some info messages), you need to return cancelled.

Reimplemented from KexiViewBase.
Definition at line 105 of file kexiqueryview.cpp.

tristate KexiQueryView::executeQuery ( KexiDB::QuerySchema * query ) [protected]

Executes query query, filling the table view with query results.
Returns:
true on success, false on failure and cancelled when user has cancelled execution (for example when she pressed the Cancel button of the "Enter Query Parameter" input dialog.

tristate KexiQueryView::storeData ( bool dontAsk = false ) [protected, virtual]

Tells this view to store data changes on the backend. Called by KexiDialogBase::storeData(). Default implementation:

makes a deep copy of sdata
stores object schema data sdata in 'kexi__objects' internal table using Connection::storeObjectSchemaData(). If dontAsk is true, no question dialog will be shown to the user. The default is false.

Reimpelment this for your needs. Should return true on success or cancelled when the task should be cancelled.

KexiDB::SchemaData * KexiQueryView::storeNewData ( const KexiDB::SchemaData & sdata,

bool & cancel

) [protected, virtual]

Tells this dialog to create and store data of the new object pointed by sdata on the backend. Called by KexiDialogBase::storeNewData(). Default implementation:

makes a deep copy of sdata
stores object schema data sdata in 'kexi__objects' internal table using Connection::storeObjectSchemaData(). Reimpelment this for your needs. Requirements:
deep copy of sdata should be made
schema data should be created at the backend (by calling KexiViewBase::storeNewData(const KexiDB::SchemaData& sdata)), or using Connection::storeObjectSchemaData() or more specialized method. For example, KexiAlterTableDialog uses Connection::createTable(TableSchema) for this (tableschema is SchemaData subclass) to store more information than just a schem adata. You should use such subclasses if needed. Should return newly created schema data object on success. In this case, do not store schema object yourself (make deep copy if needed).
