Inheritance diagram for KexiFormView:

Detailed Description
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.

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.

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 QPoint(-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 QPoint(40, 40) will be set. Called by:

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.

Reimplemented to update resize policy. Definition at line 917 of file kexiformview.cpp. |

Handles field(s) dropping from the data source pane onto the form.

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

|
Called after loading the form contents (before showing it). Also called when the form window (KexiDialogBase) is detached (in KMDI's Child Frame mode), because otherwise tabstop ordering can get broken. |
Member Data Documentation
|
Reimplemented after KexiViewBase. Updates actions (e.g. availability). Definition at line 177 of file kexiformview.h. |
|
For new (empty) forms only: Our form's area will be resized more than once. We will resize form widget itself later (in resizeEvent()). Definition at line 201 of file kexiformview.h. |
|
Database cursor used for data retrieving. It is shared between subsequent Data view sessions (just reopened on switch), but deleted and recreated from scratch when form's "dataSource" property changed since last form viewing (m_previousDataSourceString is used for that). Definition at line 185 of file kexiformview.h. |
|
True, if m_query is created as temporary object within this form. If user selected an existing, predefined (stored) query, m_queryIsOwned will be false, so the query object will not be destroyed. Definition at line 194 of file kexiformview.h. |
|
Used in setFocusInternal().
Definition at line 204 of file kexiformview.h. |
|
Used in setUnsavedLocalBLOBs().
Definition at line 215 of file kexiformview.h. |
|
Stores geometry of widget recently inserted using insertAutoFields() method. having this information, we'r eable to compute position for a newly inserted widget in insertAutoFields() is such position has not been specified. (the position is specified when a widget is inserted with mouse drag & dropping but not with clicking of 'Insert fields' button from Data Source pane) Definition at line 212 of file kexiformview.h. |
