The KexiFormView lass provides a data-driven (record-based) form view .
The KexiFormView can display data provided "by hand" or from KexiDB-compatible database source.
This class provides a single view used inside KexiDialogBase. It takes care of saving/loading form, of enabling actions when needed. One KexiFormView object is instantiated for data view mode and a second KexiFormView object is instantiated for design view mode.

Inserts autofields onto the form at pos position. sourceMimeType can be "kexi/table" or "kexi/query", sourceName is a name of a table or query, fields is a list of fields to insert (one or more) Fields are inserted using standard KFormDesigner::InsertWidgetCommand framework, so undo/redo is available for this operation.
If multiple fields are provided, they will be aligned vertically. If pos is TQPoint(-1,-1) (the default), position is computed automatically based on a position last inserted field using this method. If this method has not been called yet, position of TQPoint(40, 40) will be set.
Called by:
- slotHandleDropEvent() when field(s) are dropped from the data source pane onto the form
- KexiFormManager is a used clicked "Insert fields" button on the data source pane.
todo unnamed query colums are not supported
todo add autolabel using field's caption or name
todo this is hardcoded!
todo this name can be invalid for expressions: if so, fall back to a default class' prefix!

- Returns
- preferred size hint, that can be used to resize the view. It is computed using maximum of (a) otherSize and (b) current KMDI dock area's size, so the view won't exceed this maximum size. The method is used e.g. in KexiDialogBase::sizeHint(). If you reimplement this method, do not forget to return value of yoursize.boundedTo( KexiViewBase::preferredSizeHint(otherSize) ).

◆ setForm()
◆ setUnsavedLocalBLOB()
Assigns id local (static) BLOB's identifier for widget widget. Previously assigned BLOB will be usassigned. If id is 0, BLOB is unassigned and no new is assigned.
This method is called when a widget supporting BLOB data (currently, images from KexiDBImageBox, within KexiDBFactory) has BLOB assigned by identifier id. BLOB identifiers are defined by KexiBLOBBuffer (KexiBLOBBuffer::self() instance).
The data collected by this method is used on form's design saving (in design mode). Local BLOBs are retrieved KexiBLOBBuffer::self() and stored in "kexi__blobs" 'system' table. Note that db-aware BLOBs (non local) are not handled this way.
- Todo
- if there already was data assigned, remember it should be dereferenced

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. - See also

◆ storeNewData()
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).
