bool KexiDBForm::cursorAtStart  )  [virtual]
 

Returns:
true if the item widget's cursor (whatever that means, eg. line edit cursor) is at the beginning of editor's contents. This can inform table/form view that after pressing "left arrow" key should stop editing and move to a field on the left hand.

Implements KexiDataItemInterface.

QString KexiDBForm::dataSource  )  const [inline]
 

Returns:
the name of the data source for this widget. Data source usually means here a table or query, a field name or an expression.

Reimplemented from KexiFormDataItemInterface.

Definition at line 63 of file kexidbform.h.

QCString KexiDBForm::dataSourceMimeType  )  const [inline]
 

Returns:
the mime type of the data source for this widget. Data source mime type means here types like "kexi/table" or "kexi/query" in.the data source is set to object (as within form or subform) or is empty if the data source is set to table field or query column.

Reimplemented from KexiFormDataItemInterface.

Definition at line 64 of file kexidbform.h.

void KexiDBForm::drawRects const QValueList< QRect > &  list,
int  type
[virtual]
 

This function draws the rects in the list in the Form, above of all widgets, using double-buffering. type can be 1 (selection rect) or 2 (insert rect, dotted).

Implements KFormDesigner::FormWidget.
