protectedslot

Definition at line 763 of file kexiquerydesignerguieditor.cpp.

◆ afterSwitchFrom()

tristate KexiQueryDesignerGuiEditor::afterSwitchFrom ( int mode)
protectedvirtual

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.

◆ beforeSwitchTo()

tristate KexiQueryDesignerGuiEditor::beforeSwitchTo ( int mode,
bool & dontStore )
protectedvirtual

called by KexiDialogBase::switchToViewMode() right before dialog is switched to new mode By default does nothing. Reimplement this if you need to do something before 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. Set dontStore to true (it's false by default) if you want to avoid data storing by storeData() or storeNewData().

testing primary key here is too simplified; maybe look ar isForeignKey() or indices..

◆ storeData()

tristate KexiQueryDesignerGuiEditor::storeData ( bool dontAsk = false)
protectedvirtual

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.

◆ storeNewData()

KexiDB::SchemaData * KexiQueryDesignerGuiEditor::storeNewData ( const KexiDB::SchemaData & sdata,
bool & cancel )
protectedvirtual

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).
