//! Interface for main Table Designer's commands
/*! This interface has been specified to enable invoking Table Designer's commands
at application's level. This is used in the "altertable" test suite, available in
kexi/tests/altertable Kexi source code directory.
KexiTableDesignerInterface is implemented by KexiTableDesignerView, so it's enough
to use dynamic_cast:
\code
KexiDialogBase *dlg = KexiMainWindowImpl::self()->currentDialog();
if (dlg) {
KexiTableDesignerInterface* designerIface
= dynamic_cast<KexiTableDesignerInterface*>( dlg->selectedView() );
if (designerIface) {
//for example, delete row #3
designerIface->deleteRow( 3, true );
}
}
\endcode
Methods of KexiTableDesignerInterface are also used by classes of KexiTableDesignerCommands
namespace (KCommand derivatives) for implementing commands execution and unexecution.
All the methods contain addCommand argument. Set if to true to get the command added
to the undo/redo buffer, what will look like real user's action. This is also needed
to poperly generate arguments for commiting the "alter table" operation.
