KexiDataAwarePropertySet Class Reference
#include <kexidataawarepropertyset.h>
Detailed Description
This helper class handles data changes of a single object implementing KexiDataAwareObjectInterface (e.g. KexiTableView) inside a KexiViewBase container.It is currently used in KexiAlterTableDialog and KexiQueryDesignerGuiEditor, and may be used for similar purposes, when each KexiDataAwareObjectInterface's row can be associated with single KoProperty::Set object, and given KexiDataAwareObjectInterface object has to inform the world about currently selected row/buffer.
Following functionality is built-in:
- auto-initializing after resetting of table view's data
- destroying single buffer that is associated with deleted row
- inserting single buffer that and associating it with new row
- all buffers are cleared when view's data is cleared (using clear())
- setting view's 'dirty' flag when needed
- signalling via KexiVieBase::propertyBufferSwitched() that current property buffer has changed (e.g. on moving to other row)

Constructor & Destructor Documentation
|
You can instantiate KexiDataAwarePropertySet object for existing tableView and view. tableView can have data assigned (KexiDataAwareObjectInterface::setData()) now but it can be done later as well (but assigning data is needed for proper functionality). Any changed reassignments of table view's data will be handled automatically. Definition at line 29 of file kexidataawarepropertyset.cpp. |
Member Function Documentation
|
Inserts buf buffer at row position. If there was a buffer at this position before, it will be destroyed. If newOne is true, the property buffer will be marked as newly created, simply by adding "newrow" property. The buffer buf will be owned by this object, so you should not delete this buffer by hand but call removeCurrentPropertySet() or remove(uint) instead. Note that buffer's parent (QObject::parent()) must be null or qual to this KexiDataAwarePropertySet object, otherwise this method will fail with a warning.

Removed a buffer at row position. Definition at line 79 of file kexidataawarepropertyset.cpp. |
|
Emmited when row is deleted. KexiDataAwareObjectInterface::rowDeleted() signal is usuallly used but when you're using KexiDataAwarePropertySet, you never know if currentPropertySet() is updated. So use this signal instead. |
|
Emmited when row is inserted. Purpose of this signal is similar to rowDeleted() signal. |
|
Called on selecting another cell in a tableview.
